Within Hearts of Iron IV, there are several types of data structures, used to store data to be used for later. This can be used in-game as a way to check if some effect block was executed or not, as a counter of sorts, or something else.
Constants
Constants serve as a way to use the same value with a reference. The constants are marked with the @ symbol when defining or using them. An example definition is the following:
@CONSTANT_1 = 10 @CONSTANT_2 = "TAG_my_idea"
This can later be used in the file as, for example, cost = @CONSTANT_1. These definitions can be in any point of the file.
Constants are available in the vast majority of game files, including most, if not all, *.txt and *.gui files. Constants can be used as a way to link several values to be the same if they can easily be changed at any point in the development. However, constants that store a string for its value can only be used in triggers and the attributes of elements and windows, trying to use them in an effect will result in an "invalid database object for effect/trigger" error.
For example, if there is a large decision system where every decision is intended to have the same cost, then these constants may be used if the political power cost gets changed mid-development for better balance.
Another example would be a scripted GUI container: if a large multitude of elements are to be at the same X or Y position, it might be worth it to link them to be a constant in case their position could be changed for better appearance or to fit in another GUI element.
Example decision file that utilises constants:
@CONSTANT_1 = 10
@CONSTANT_2 = "TAG_my_idea"
TAG_decision_category = {
TAG_decision = {
icon = test_icon
cost = @CONSTANT_1
complete_effect = {
if = {
limit = {
has_ideas = @CONSTANT_2
}
add_stability = 0.1
}
}
}
}
Defines
- 主条目：Defines
Defines are a particular type of constant that are used within internal calculations only, defined within /Hearts of Iron IV/common/defines/*.lua files. These cannot be referenced in any other files and are only used within the internal, unchangeable code.
Some of the things included in the defines are that events by default stay for 13 days before auto-selecting the first option[1] or that the ai_will_do value is 50% higher for focuses which were unlocked by the just-completed focus[2]. Most defines are numerical in nature, but some can be strings or blocks, such as the end date at which the game over screen appears[3] or the list of experience need for a division to progress to the next level[4].
The list of defines is vast and touches on every mechanic in the game, so if something can't be changed within the mechanic's respective files, it may be worth to check defines. Defines don't include the Modifiers#Static modifiers, which can serve a similar purpose but with modifier blocks.
As defines are Lua code rather than a PDXscript-interpreted file, any Lua code can go in there, however modules allowing to go out of this directory are not available. As a consequence of this, there is no need to copy the entire file to edit it. Defines, including graphical defines, are merely a Lua-contained array, and it is possible to modify a single member of the array in Lua using, for example, NDefines.NGame.START_DATE = "1936.1.2.12". Each of these lines is contained on a separate line and there are no commas separating them, such as the following:
NDefines.NGame.START_DATE = "1936.1.2.12" NDefines.NGraphics.COUNTRY_FLAG_TEX_MAX_SIZE = 2048
This goes into a separate file set to be evaluated after the base game defines, which is done by making the filename be later in the alphabetical order (decided by Unicode character IDs). As most Unicode characters (including every uppercase or lowercase letter) have larger IDs than the code used for the number 0, the filename is almost irrelevant.
In the base game files, the graphical defines are set to be merged into NDefines in the last line of the base game file. However, since Lua does not create copies of tables by default, the base game's NDefines contains pointers to the actual elements, which are contained within NDefines_Graphics regardless. For this reason, modifying either NDefines or NDefines_Graphics works for changing graphical defines.
A mod should never contain the 00_defines.lua and 00_graphics.lua files within of itself: these files are commonly changed even in minor game updates, and having a define missing from a file results in the mod being unstable, potentially having a crash on startup.
Flags
In this case, flags are used in the sense of a computer variable that is used to set data to and later read it from, commonly but not necessarily of a boolean value (i.e. either 0 or 1). For editing the flags used for representing countries in-game, see Country creation for the starting flags and cosmetic tags for changing them in the middle of the game.
Flags within PDXScript are a 32-bit signed integer, ranging from -2147483648 to 2147483647. A flag can only be set to a specific value (Potentially for a certain amount of days), modified in an additive way by a certain value and read, no other operations can be done. Variables serve as a more operational alternative, with far more capacity for changing (Such as multiplication or non-integer values, reading game values, being able to set to other database entries rather than numbers, etc). Flags are still recommended to use as a boolean value, as these are more optimised than the variables, and so using variables will lead to an unnecessary increase in memory usage and will lead to the game running slower compared to flags.
Flags are divided into 5 scopes:
- Global. These can be read from anywhere in the game, without the need for scoping.
- Country. These are assigned to individual countries, being impossible to assign or read elsewhere. A country flag can have different values depending on which country it's checked in.
- State. These are assigned to individual states, being impossible to assign or read elsewhere. A state flag can have different values depending on which state it's checked in.
- Character. These are assigned to individual characters, being impossible to assign or read elsewhere. A character flag can have different values depending on which character it's checked in.
- Military industrial organisation. The
mioshortnening is used in code for them, such asset_mio_flag.
In general, the same principles apply to them with little changes. While unit leader flags exist, these are marked as deprecated and are likely to be removed within the next updates.
A flag can be set in any effect block. There is no file where flags need to be defined, they will exist if set and stop existing when cleared.
The simplest formatting for setting a flag is set_country_flag = my_flag_name. This will create the country flag (If it did not exist otherwise) and set it to be a value of 1. This has no tooltip and so it will be invisible to the player. custom_effect_tooltip may be used to tell the player that something will be done, if wanting to keep them in the know.
Afterwards, that flag can be checked with has_country_flag = my_flag_name as a trigger. This is set to be true if the flag was set, regardless of which value it has. This will create a tooltip using the flag's name as the localisation key. As such, my_flag_name: "Has my flag" will make that appear when the country flag is checked.
If a flag is no longer useful, it can be cleared by using clr_country_flag = my_flag_name, which'll mark it as no longer being set. This also has no tooltip and the player will not be aware unless specifically told with the custom effect tooltip that the flag was cleared.
The exact same principles apply with global, state, and character flags. The only differences are in the used effects/triggers (In which case the word country is swapped with the type's name like set_global_flag, has_state_flag, or clr_character_flag) scopes in which they can be set and where they can be checked. For global flags, it can be done in any scope rather than the 'global' scope: it can be set in either country, state, character, or rare other scopes.
Flags can also be targeted towards a certain country. This is usually done by appending the @TAG to the name of the flag, though it can be placed anywhere within the tag name except for the first character. For example, set_country_flag = my_targeted_flag_@PREV will set it to be targeted towards the country represented by PREV, which we'll take as TAG. This just appends the PREV's tag to the flag's name. After this, has_country_flag = my_targeted_flag_TAG will come up as true for the same country it was set in. This can be used to create dynamic flags without relying on meta effects. You cannot have more than one target specifier in a single tag, You can only use @ROOT, @PREV, @FROM, and @THIS, even @PREV.PREV does not work. Both of these restrictions do not apply to targeted variables, so those may be a more flexible alternative if you need.
Example
The most common use of flags is to simply to mark a certain event (in the generic sense of a word, not necessarily the in-game event mechanic) as having occurred, such as an election, an invasion, a diplomatic deal, et cetera. For example, here's an event that starts off an election campaign in the country:
country_event = {
id = algeria_election.0 # Namespace is assumed to exist.
title = algeria_election.0.t
desc = algeria_election.0.desc
is_triggered_only = yes
immediate = {
set_country_flag = ALG_1936_elect_campaign # Since set_country_flag has no tooltip, no need to hide it.
}
option = {
< ... > # Irrelevant what's in the option
}
}Flags provide a way to mark that this event has been received, in this case set within the immediate effect block of the event.
In order to utilise this, the has_country_flag trigger will have to be used similarly to this example decision:
ALG_1936_campaign_category = { # Decision category is assumed to exist and contain 'allowed = { tag = ALG }'
ALG_1936_select_candidate_A = {
available = {
has_country_flag = ALG_1936_elect_campaign
}
icon = ALG_elect
cost = 50
fire_only_once = yes
complete_effect = {
country_event = algeria_election.1
}
}
}
This will work fine, however, as is, the player will see either a 
check mark or a 
cross next to 'ALG_1936_elect_campaign', with no indication what that truly means. In order to correct that, a localisation entry can be added to any working localisation file (i.e. is an *.yml file within the /Hearts of Iron IV/localisation/ folder or any of its subfolders, has the internal name of the language in the end of filename before the extension, and is encoded in UTF-8 with the byte order mark present):
ALG_1936_elect_campaign: "The 1936 election campaign is currently ongoing"
In order to clear the flag when needed, the clr_country_flag effect would be used as such:
country_event = {
id = algeria_election.100 # Namespace is assumed to exist.
title = algeria_election.100.t
desc = algeria_election.100.desc
is_triggered_only = yes
option = {
name = algeria_election.100.a
trigger = {
has_country_flag = ALG_candidate_A_won
}
clr_country_flag = ALG_1936_elect_campaign
< ... > # Irrelevant what else is in the option
}
option = {
name = algeria_election.100.b
trigger = {
has_country_flag = ALG_candidate_B_won
}
clr_country_flag = ALG_1936_elect_campaign
< ... > # Irrelevant what else is in the option
}
< ... > # Other potential options
}
Note that neither of the effects that modify country flags have tooltips, so a custom effect tooltip can be used to notify the player in some cases.
Everything is the exact same for flags of other scope types.
Non-boolean usage
This will cover the non-boolean usage of flags. Variables usually do this job better, but this still has some usages.
The set_<type>_flag effect can also be expanded with the optional days and value arguments. This will appear like the following:
set_state_flag = {
flag = my_state_flag
days = 50
value = 3
}This in particular will set the flag my_state_flag to the state to be equal to 3 for 50 days. After these 50 days end, the flag will be cleared completely, reset to 0. If days are left out, the flag will be set to that value forever. If the value is left out, the flag will not be changed.
And the trigger if a flag is set can also be expanded as such:
has_global_flag = {
flag = my_global_flag
value > 2
days > 30
date < "1938.1.1"
}While the flag and the value arguments are self-explanatory, days checks how many days it was since the flag was set (Not how many are remaining), while the date checks the date at which the flag is set. Every argument aside from the flag one is optional, just assumed to be always true if not set. This trigger will still always fail if the flag was never set or if it was cleared.
Additionally, it is possible to modify a flag as such:
modify_character_flag = {
flag = my_character_flag
value = 4
}This adds the amount to the flag, with negatives being possible. However, there's one catch: this does nothing if the flag is not set, having a value of 0.
Each of the preceding examples can be used for any flag type.
Debugging
The following console commands exist for debugging variables. In console commands, the 'current scope' is what is currently selected: the country opened in diplomacy, the state selected, the unit leader that's selected. If left out, assumes to be the player country.
| Name | Parameters | Examples | Description |
|---|---|---|---|
| set_country_flag | <flag>The name of the flag to set. |
set_country_flag my_flag |
Sets the country flag for the country controlled by the player. |
| set_global_flag | <flag>The name of the flag to set. |
set_global_flag my_flag |
Sets the global flag. |
| list_flags | <scope>Optional. Changes the scope from the currently-selected scope to what's specified.
|
list_vars |
Lists currently active flags in the console window, with their value. Context senstive if nothing (global_flag), country (country_flag) or state (state_flag) is selected when entering this command. |
Event targets
Event targets serve as a primitive way to set a pointer to a scope (country, state, character) to be referred to later. Any single event target can only point towards a single scope at a time, however a scope may have several event targets at the same time. Similarly to flags, there is no set folder for event targets, they can be assigned in any event block.
There are two types of event targets: regular and global. The difference between them is purely when they get cleared.
A scope can be checked if it has an event target assigned using has_event_target = name_of_event_target.
Global event targets
Global event targets can be declared using save_global_event_target_as = my_event_target as an effect. This will create the global event target with the name of my_event_target and it will last forever. Afterwards, it can be referred to as event_target:my_event_target, both as a scope and as a target.
If save_global_event_target_as = my_event_target is used when the event target is already set, the event target will change scopes to the one where the effect is used.
Additionally, clear_global_event_target = my_event_target (to be used in any scope, not necessarily the event target) will clear the specified global event target entirely, while clear_global_event_targets = ROOT will clear every global event target from the specified scope.
For example, by using start_civil_war as an effect block, the following will assign the TAG_democratic_side event target to the revolter:
start_civil_war = {
size = 0.5
ideology = democratic
save_global_event_target_as = TAG_democratic_side
}
After this, TAG_democratic_side event target will refer to the democratic side. For example, this code later in another effect block can be used to transfer a state and a part of the armies to the event target:
event_target:TAG_democratic_side = {
transfer_state = 123
}
transfer_units_fraction = {
target = event_target:TAG_democratic_side
size = 0.2
}
It would make sense to clear the event target after it no longer exist, such as by using the on_civil_war_end on action.
When using the event target as a scope for a namespace in localisation, the event_target: prefix is not needed, instead it'll look like [TAG_democratic_side.GetName].
Regular event targets
Regular event targets can be declared using save_event_target_as = my_event_target as an effect. The difference between regular and global event targets is in when they get cleared. While global event targets are used forever and can only be cleared manually, regular event targets only last as long as the effect block does (carrying over into events fired within as well), clearing automatically afterwards, and there is no way to clear them manually.
For example, this in an effect block will save a random owned and controlled state as the event target target_state and then fire the event mod_event.0 in 10 days:
random_owned_controlled_state = {
save_event_target_as = target_state
}
country_event = { id = mod_event.0 days = 10 }
Assuming no other events, this event target will only exist within this effect block and the event mod_event.0 (Where it can be used in its corresponding trigger or effect blocks). If the event mod_event.0 fires another event within a corresponding effect block, this event target will exist in that event as well, meaning that this carries over to the entire mod_event.0-starting event chain. For example, the generic event generic.23 ([From.GetNameDefCap] Demands Control of [demanded_prov_target.GetName]) uses this with demanded_prov_target as the event target. In order to make ROOT demand the state 123 from TAG using this, this effect block will be used:
123 = {
save_event_target_as = demanded_prov_target
}
TAG = {
country_event = generic.23
}
Event targets can be used in most effect blocks, they are called event targets only because they carry over to events. However, there are a few effect blocks, such as scripted diplomatic actions, where event targets are impossible to set.
Country tag aliases
Country tag aliases are somewhat similar to event targets: they are used as pointers towards a specific scope, a single alias can point towards a single scope, and a single scope can have several aliases. However, there are differences. Primarily, country tag aliases can only point towards countries (as per the name) and they are set and cleared entirely automatically without any manual involvement. A country tag alias can point towards a non-existing country.
Country tag aliases are stored within /Hearts of Iron IV/common/country_tag_aliases/*.txt files. Each country tag alias is stored as a separate block within the file, with the name of the block being the name of the alias. Additionally, the country tag aliases serve as a trigger block, so any trigger can be used within. These are the arguments that can be used within:
variable = global.var_name- This will make sure that the country tag alias is equivalent to the country that the specified variable points to, in this casevar_nameassigned to the global scope.event_target = my_event_target- This will make sure that the country tag alias is equivalent to the country that the specified regular event target points to, in this casemy_event_target.global_event_target = my_event_target- This will make sure that the country tag alias is equivalent to the country that the specified global event target points to, in this casemy_event_target.original_tag = TAG- This puts every country that originates from TAG (created with start_civil_war or create_dynamic_country) as a possible target for the alias. In this case, further specification is needed with triggers. This is equivalent to the original_tag trigger, but this is treated as an argument here as it does make certain errors go away.targets = { ABC DEF GHI }- This is a whitespace-separated list of country tags that the country tag alias can select. In this case, further specification is needed with triggers.target_array = global.my_array- This puts every country that's within the specified array (my_arrayin the global scope in this case) as a possible target for the country tag alias. In this case, further specification is needed with triggers.country_score = { ... }- This is a MTTH block evaluated for each country. The country which has the highest total score will be picked for the country tag alias, provided the conditions imposed by every other argument are met.fallback = TAG- This is what the country tag alias will point to if no country fulfills the conditions specified within triggers or other arguments.
Here are some examples of country tag aliases:
MOD = {
targets = { ABC DEF GHI }
has_country_flag = my_flag
country_score = {
base = 1
modifier = {
add = 2
tag = ABC
}
modifier = {
add = 1
tag = DEF
}
}
fallback = ABC # This will point to ABC, DEF, or GHI if they have the specified country flags. ABC is prioritised over DEF, which is prioritised over GHI. If neither have the country flag, defaults to ABC.
}
ARB = {
target_array = global.arab_countries
has_cosmetic_tag = ARABIA_UNITED # This will point to any country in the global.arab_countries array if they have the ARABIA_UNITED cosmetic tag, provided they exist.
exists = yes
}
This is most commonly used with start_civil_war or create_dynamic_country. For example:
SDA = {
original_tag = SDI
has_country_flag = SDI_side_A
}
In order for this country tag alias to get used for side A of the civil war, it must have the country flag set. This is usually done directly in the effect that spawns it:
start_civil_war = {
ideology = neutrality
size = 0.5
set_country_flag = SDI_side_A
} After doing this, it's possible to use SDA as if it's a regular country tag, e.g. SDA = { add_political_power = 100 } or transfer_state_to = SDA.
separate from the method above another easier method to give custom tag to a dynamic d## country eg d04 (this method does not require a flag to be set)
in common\country_tag_aliases\tag_aliases.txt add
INA = { #new tag
original_tag = INS
has_government = monarchism #change monarchism to democratic etc to define which faction you want
}
The INA tag above will be functional without any other changes e.g. INA = { add_political_power = 100 }
using a limit
if = { ## Put this inside completion reward in a focus to create a custom cosmetic tag for a dynamic country,
limit = { ##checks both conditions below match
any_country = { original_tag = INS } ##INS is original country Tag
NOT = { has_government = democratic } ## democratic/neutrality etc is government type change it to usually the government type of the original country or , custom ideologies can be used here too.
} ## if the civil war has MORE than 2 factions of differing government types copy the NOT line and enter the third factions government type.
set_cosmetic_tag = INA ## set any country matching the above conditions to cosmetic tag INA that can be used.
}
To Change a Dynamic country Name the name file you need is \localisation\countries_cosmetic_l_english.yml
add the below lines (rename inside " " to suit your needs)
INA:0 "Indonesia Royalist uprising" #INA is new cosmetic tag created above INA_AST_autonomy_puppet_DEF:0 "Royal $OVERLORDADJ$ Indies" # will change name to overlords adjective
Variables
A variable within Hearts of Iron IV is a signed 32-bit fixed point number with scaling of [math]\displaystyle{ \frac{1}{1000} }[/math]. As such, it ranges from -2 147 483.648 to 2 147 483.647. Adding further amounts above or below the variable will result in an overflow, causing the value go from the maximum to the minimum or vice-versa.
Variables are not stored within any particular file and can be created dynamically with any effect or (temporary variables-only) trigger. Each database object (such as countries, states, ideas, or even equipment types) has a unique internal numeric ID, which can be assigned to a variable. For example, setting a variable's value to a country tag will make it take on the ID of the tag, and then the variable will be taken as a country when used as a target or as a scope. For tokenizable database types, a token: prefix is necessary when assigning a literal, for example: var_name = token:some_idea_name.
When using a variable as a scope, the var: prefix is needed, however in some cases the prefix is optional: most notably when using it as the target of an effect or trigger. For example, in transfer_state = var:my_state_variable, the var: can be omitted with no difference (For some cases, there will be logged errors, yet it will work in-game), but in var:my_country_variable = { transfer_state = 123 } the var: is mandatory. Despite functioning similarly to a scope, the var: prefix is optional when a variable is used as a weight inside of random_list. Same as with event targets, using variables in localisation for namespaces does not require the var: prefix, such as [var_name.GetName]. A good rule of thumb is that when passing a variable in a place where a raw token (rather than, say, a quoted string, a number, or a numeric state ID) is acceptable, it must usually be prefixed with var: so that the parser can distinguish whether the token being passed is meant to reference a database object or a variable. If var: is absent in a location where it should be present, the code may work, but the game will often complain in the error log. In general, it is best to err on the side of caution in this regard, as what may result in a merely-complaining error in one context, might result in an effect-nullifying, or worse, trigger-falsifying, error in another context. However, var: is always optional in variable and array manipulation operators (including check_variable), and so it can be elided in those operators for readability's sake.
Within their names, variables can have any word character, i.e. the 26 English letters (Either lowercase or uppercase), underscores, and the decimal digits from 0 to 9. However, a variable name cannot begin with a decimal digit, so a name like 123_my_variable is invalid. This requirement common in many programming languages, and is implemented here for the same reason that the var: prefix exists: so that the parser can determine what syntactic type a token will be from the first (few) characters, and therefore doesn't have to worry about backtracking as much. In addition, it is recommended to avoid any names by variables that are already used for something else. For example, naming a variable capital can prevent any subsequent usage of the game variable with the same name within the internal code. A common naming convention to avoid overlap is to add a prefix signifying where it's used, such as the country's tag (POL_capital) or the name of the mechanic (Usually shortened like PC_capital).
Variable types
There are two types of variables: regular and temporary. There are the following differences between the two:
- Different effects are used to set and modify regular and temporary variables. Typically, the difference is just in changing
variabletotemp_variable. - Temporary variables only exist within the effect or trigger block where they're defined, similarly to regular event targets (although without carrying over to events). This does not mean they don't survive outside of the scope where they're defined, but the 'entire effect block, such as a focus reward or an event option. Meanwhile, regular variables exist forever. Note that this, however, does not always function properly in regards to scripted effects or triggers: temporary variables defined within of them may not still exist outside of them within the same effect/trigger block. However, a temporary variable defined before the scripted effect or trigger's usage will always carry on into it and get modified properly within.
- Due to the previous point, temporary variables can be defined and modified in trigger blocks as well as in effect blocks. This enables them to be computed as-needed in scripted triggers called from the
triggerblock of scripted localizations. Meanwhile, regular variables are restricted to only being defined in effect blocks. - Temporary variables are unscoped: they will remain the same regardless of in which scope they're defined and where they're checked. Meanwhile, regular variables are restricted to scopes, so that the variable has different values depending on which scope it's checked in, such as how different countries may have different stability values.
Scoping
Scoping only exists for regular variables. They can and must be assigned to countries, states, characters, and to the global scope.
If nothing else is specified, the current scope, or THIS, is used as the scope of the variable. For example, ABC = { set_variable = { my_var = 1 } } will set the variable with the name of my_var within the scope of ABC. CBA = { check_variable = { my_var = 1 } } would then come up as false, since it checks for the variable only within CBA, while the variable is set in ABC.
The scope where the variable is read can be changed by prepending any dual scope that can be used as a target before the variable's name, separated with a dot, such as PREV.PREV.var_name being the value of var_name as checked for PREV.PREV or event_target:my_event_target.var_name. This also includes global in order to assign it globally, which is necessary to scope into global. Other variables, if pointing to a scope, can also be used, but the var: is unneeded. Variables must be chained using the : separator (rather than the usual dot), such as ABC.capital:var_name being the variable var_name as it's assigned to the capital state of the country ABC, where capital is a built-in variable pointing to the capital state of the country. Note that the scope specifier preceding capital is separated from it by a . since it is a static (that is, non-variable) scope. The way to intuit this syntax is that the whole ABC.capital clause forms a variable scope specifier, in which var_name is accessed.
Here are some examples of scoped variable references:
var_name # Scopes to THIS GER.var_name # Scopes to GER 123.var_name # Scopes to state 123 global.var_name # Scopes to global province_controllers^1234:capital:var_name # Scopes to the capital state of the country that controls the province 1234.
In practice, scoping to distinguish variables may look like this:
every_country = {
set_variable = { weighted_manpower = 0 } # Reset the counter to default in case it already exists
every_owned_state = {
set_variable = { weighted_manpower = state_population_k } # Completely unrelated to the above variable due to being in a different scope
if = {
limit = {
NOT = { is_core_of = PREV } # Is core of the owner
}
divide_variable = { weighted_manpower = 10 } # Divides the state's equivalent
}
add_to_variable = { PREV.weighted_manpower = weighted_manpower } # Adds to the owner's counter
}
}In this case, each state has a weighted_manpower variable which is equal to the population in thousands if it's a core of the owner at the time of being set and it's divided by 10 otherwise. Each country will also have a weighted_manpower variable, which sums up the weighted manpower of each state. Despite having the same name, these variables are completely unrelated to each other due to one being country-level and the other being state-level.
Trigger usage
Only temporary variables can be modified within a trigger block. Regular variables can only be used in effects, while temporary can be used in both triggers and effects.
However, there's one aspect of triggers that's important to know: when each scope stops evaluating. If a scope stops evaluating, then the variable will not be modified anymore. In general, trigger scopes that can select multiple targets are divided into two groups: all_<scope type> and any_<scope type>. The first group, requiring all targets to meet triggers, evaluates each target in order and stops when it encounters one where the triggers aren't met. The second group, requiring any target to meet triggers, evaluates each target and stops when it encounters a true one.
Empty trigger blocks are considered true by default, so one would instantly stop the validation of the second group (any_ triggers). For this reason, since scope limits are not supported in trigger scopes, then the proper usage for modifying temp variables would be an if statement that modifies the variable if the limit is met with no other triggers that can come up as true or false coming up.
Localisation
- Parts of this section are transcluded from Localisation § Formatting variables
In order to display the value of a variable in localisation, [?var_name] is used, with the question mark signifying that it's a variable. The question mark is mandatory in order to distinguish the variable from the event targets. For example, such a localisation value will work: var_value_tt: "There are [?num_of_dogs] dog(s) in the country"
By default, the scope where this is used gets assumed. Scoping works the same way as it does with variables regularly: GER_var_value_tt: "There are [?GER.num_of_dogs] dog(s) in [GER.GetNameWithFlag]"
When the variable is a scope by itself, the question mark is still mandatory to use to distinguish from event targets: target_tt: "The target country is [?target_country.GetName]". Variables can only be displayed in UI that supports dynamic localisation, otherwise it will appear exactly as in the localisation file. List of such UI elements and necessary conditions for them to support dynamic localisation can be found in Localisation § Namespaces.
If the variable points to a certain address with more localised text, such as a country, namespaces can be used in the same manner as with a regular tag or event target: most_dogs_tt: "[?most_dogs.GetNameDefCap] has the most dogs out of any country." Question marks are still mandatory to include in this case.
Variables have a unique way for applying colouring, also allowing extra formatting characters. These are applied after a pipe placed at the end of the variable's name, such as [?my_variable|R] that will turn the colour of the variable my_variable red. If no colouring is applied, it will use the same colour as regular text: the §-colour block, textbox's text_color_mode, or the font's default colour in that order.
The list of formatting characters that are restricted to variables only are the following:
| Code | Effect |
|---|---|
| * | Converts the variable to SI units—appends "K" or "M" and divides the variable appropriately, such as 65 536 becoming 65.53K and 1 500 000 becoming 1.50M. Displays 2 decimals after the dot by default. |
| ^ | Same as *. |
| = | Prefixes the variable with + if the value is positive or - if it is negative. |
| 0..9 | Controls the number of decimals to display. Due to the nature of the game's variables, there are no more than 3 decimals that can be shown. Using any digit greater than 3 will instead have the same result as 3. |
| % | Converts the variable to percentage, multiplying by 100 and appending a %. By default, will show 2 digits after the decimal point, though the second digit will always be 0. |
| %% | Appends a percentage to the end of the variable without multiplying by 100. |
| + | Colours the variable green if positive, yellow if zero, red if negative. |
| - | Colours the variable red if positive, yellow if zero, green if negative. |
Any unrecognised symbols will neither change how the variable is localised nor get recognised as an error in-game. For example, it's common practice in the base game to prepend a dot before the digit used to control the amount of displayed digits as [?var|.1]. In case of overlap between mutually-exclusive rules, the last-used one will be prioritised. However, static colouring has a lower priority than dynamic colouring (e.g. [?var|+Y] will be treated as [?var|+]), and using %% will also override %.
Some examples of formatting characters in usage:
l_english: loc_key: "Democratic party popularity: [?party_popularity@democracy|%G0]" loc_key_2: "Modifier token's value: [?modifier@my_modifier|.1%%+]" pol_power_trigger_tt: "Has more than [?var_name|Y] political power"
Within these examples, the first string depicts the current scope's democratic popularity as a percentage multiplied by 100 (%), in green (G), rounded to a whole number with 0 decimals (0). The second string displays the my_modifier modifier token's value as a 'good' number (+ making it green if positive, red if negative), with a percentage sign appended in the end (%%) and rounded to a number with one decimal (.1). The third string displays the variable in yellow colouring (as is common in the base game's tooltips), leaving it unchanged otherwise.
By default, variable-related arguments such as set_variable or check_variable do not have a tooltip. For some of these arguments, such as add_to_temp_variable, it is possible to set a tooltip with an optional tooltip = localisation_key argument within. Others, such as check_variable, do not support this and a custom tooltip must be used instead, whether it's for effects or for triggers.
This tooltip argument is notable since the value of that localisation key allows using two strictly-internal variables marked with dollar signs: $LEFT$ and $RIGHT$.
$LEFT$ represents the variable's value before the operation, while $RIGHT$ represents the variable's value after the operation. This can be used to let the player know the current and/or the potential value of the variable in the same localisation key without taking up more space with custom_effect_tooltip.
Here's an example of it being done:
add_to_variable = {
var = num_dogs
value = ENG.num_cats
tooltip = add_cats_to_dogs_tt
}This is the effect itself. Within localisation, this would be done:
add_cat_to_dogs_tt: "Adds [ENG.GetAdjective] cats to our $LEFT$ dog(s) to get $RIGHT$ in total."
Additional usage
By default, an unset variable is equal to zero when checked. However, the game also provides a null coalescing operator for variables, used with a question mark. For example, cost = var_name?100 within a decision will result in the cost of the decision being the same as var_name for the country. However, if that variable was never set or was cleared beforehand, then the decision will cost 100 
政治点数 instead of 0.
Similarly to flags, a variable can be set as targeted by appending the target with @TAG. However, there are differences: in variables this does not append the target's ID to the name but stores it as a separate variable, as well as it being possible to target far more than countries, but also, for example, states or ideology groups. A variable reference var_name_@GER would resolve to a variable named var_name_GER. If called in a scope where PREV= { tag = ENG }, a variable reference var_name_@PREV would resolve to a variable named var_name_ENG. This can even be applied to temporary variables. You can also target variables using the syntax var_name_@var:target_var_name, regardless of the type of their value: be it country, state, token, even a raw integer. Variables targeting tokenizable types such as ideology groups and ideas provides a powerful alternative to scoped variables for associating a set of variable fields together, enabling one to get around the fact that ideas, ideologies, etc. do not have their own scopes. Generally, when you target a token, it is pasted in as its underlying integer ID (a number in the ten-thousands, usually), but this generally works fine, because it's consistent; the only problem is it's not human-readable. In general, variable targeting is substantially more optimized than meta-effect/trigger token pasting, not to mention more readable and understandable, so should be preferred wherever feasible.
It is technically possible, under some circumstances, to use multiple target specifiers in one variable name, usually strung together back-to-back at the end of the name, like var_name_@THIS_@PREV. However, this is extremely inconsistent, and the exact rules that govern how it behaves are currently an open question.
Operators
The following is a list of variable-related effects and triggers. Variable-modifying effects have an equivalent for temporary variables, with temp_variable being used instead of variable, and these temporary variable operators are also valid triggers, as described above. Every operator can be used with variables that do not exist, assuming a value of 0 unless a null-coalescing operator is used.
| Name | Parameters | Examples | Description | Notes |
|---|---|---|---|---|
| set_variable | var = <variable>The variable to modify or create.
|
set_variable = {
var = my_variable
value = 100
tooltip = set_var_to_100_tt
}
set_temp_variable = { temp_var = ROOT.overlord }
|
Sets a variable's value to the specified amount, creating it if not defined. | Shortened version exists with set_variable = { <variable> = <value> }.
|
| set_variable_to_random | var = <variable>The variable to modify or create.
|
set_variable_to_random = {
var = random_num
max = 11
integer = yes
}
set_temp_variable_to_random = my_var |
Sets a variable's value to the specified amount, creating it if not defined. The result will be greater than or equal than the minimum and strictly less than the maximum. | Shortened version exists with set_variable_to_random = <variable>, setting it to a decimal between 0 and 1. Can be used in triggers.
|
| clear_variable | <variable>Variable to clear. |
clear_variable = my_variable |
Clears the value from the memory entirely. | Can only be used on regular variables. |
| check_variable | var = <variable>Variable to compare.
|
check_variable = {
var = my_var
value = 10
compare = greater_than_or_equals
}
check_variable = { var_name > 10 }
|
Compares the value of a variable. Used as a trigger. | Temporary and regular formatting use the exact same formatting. Shortened variant exists as check_variable = { <variable> < <value> }, where the operator in the middle is an equality sign (=), greater than sign (>), or a lesser than sign (<). The comparison type is always strict in this case: check_variable = { var_name > 10 } will come up as false if var_name is exactly 10.
|
| has_variable | <variable>Variable to check. |
has_variable = my_variable |
Checks if the value was set, regardless of its amount. Used as a trigger. | A variable is considered set even if its value is 0, as long as it wasn't cleared. |
| add_to_variable | var = <variable>The variable to add to.
|
add_to_variable = {
var = my_variable
value = 100
tooltip = add_100_to_var_tt
}
add_to_temp_variable = { temp_var = num_owned_states }
|
Increases a variable's value by the specified amount, creating it if not defined. | Shortened version exists with add_to_variable = { <variable> = <value> }.
|
| subtract_from_variable | var = <variable>The variable to subtract from.
|
subtract_from_variable = {
var = my_variable
value = 100
tooltip = sub_100_from_var_tt
}
subtract_from_temp_variable = { temp_var = num_owned_states }
|
Decreases a variable's value by the specified amount, creating it if not defined. | Shortened version exists with subtract_from_variable = { <variable> = <value> }. Equivalent to adding a negative amount.
|
| multiply_variable | var = <variable>The variable to multiply.
|
multiply_variable = {
var = my_variable
value = 100
tooltip = multiply_var_by_100_tt
}
multiply_temp_variable = { temp_var = num_owned_states }
|
Multiplies a variable's value by the specified amount. | Shortened version exists with multiply_variable = { <variable> = <value> }.
|
| divide_variable | var = <variable>The variable to divide.
|
divide_variable = {
var = my_variable
value = 100
tooltip = divide_var_by_100_tt
}
divide_temp_variable = { temp_var = num_owned_states }
|
Divides a variable's value by the specified amount. | Shortened version exists with divide_variable = { <variable> = <value> }.
|
| modulo_variable | var = <variable>The variable to modulo.
|
modulo_variable = {
var = my_variable
value = 50
tooltip = get_modulo_of_var_by_50_tt
}
modulo_temp_variable = { temp_var = num_controlled_states }
|
Makes the variable become the remainder of Euclidean division of the variable by the specified value. | Shortened version exists with modulo_variable = { <variable> = <value> }.
|
| round_variable | <variable>The variable to round. |
round_variable = my_variable round_temp_variable = temp |
Rounds the variable towards the closest integer value. | If exactly between two integers (Such as 1.5), the larger option gets chosen. |
| clamp_variable | var = <variable>The variable to clamp.
|
clamp_variable = {
var = my_var
min = 0
}
clamp_temp_variable = {
var = my_var
min = 0
}
|
Clamps the variable to ensure its value is between the two specified numbers, raising to the minimum if smaller or lowering to the maximum if larger. | Either min or max can be omitted, in which case it'll not be checked. Does nothing if the variable is already in the range between min and max. This only changes the current value of the variable, it can still go beyond the minimum or the maximum after the clamp. |
Usage examples
A common usage for variables is to grant a more 'complex' effect or a trigger. This is best done with temporary variables, as they can be set in either triggers or effects and they're not bound to scopes making operations on them more simple.
For example, the following can take 0.1% of every controlled state's population and add it directly to the manpower pool if the country has more democratic party support than fascist and communist party support combined:
if = {
limit = {
set_temp_variable = { fascom_pop = party_popularity@fascism }
add_to_temp_variable = { fascom_pop = party_popularity@communism }
check_variable = { party_popularity@democratic > fascom_pop } # Completely hidden from the player.
} # 'limit = {}' is always hidden so it doesn't matter here, but use custom_trigger_tooltip when wanting the player to be aware.
hidden_effect = { # Every controlled state can look weird to the player otherwise.
set_temp_variable = { temp_manpower = 0 } # Optional, can be omitted as variables are assumed to be 0 if unset.
every_controlled_state = {
add_to_temp_variable = { temp_manpower = state_population_k } # Executed in the state's scope, so state_population_k is of the state.
} # Temp variables are unscoped so it doesn't matter where they're edited.
} # For regular varibles, "add_to_variable" would need to scope into the correct country such as with "PREV.temp_manpower".
add_manpower = var:temp_manpower # 'add_manpower = temp_manpower' also works
}
Since temporary variables can be set in triggers, they can be used as an alternative version of count_triggers, to count the amount of scopes where the trigger is fulfilled instead of counting the amount of fulfilled triggers:
if = {
limit = {
all_country = { # all_-typed scopes iterate over each entity until encountering a false, making them preferred over any_-typed ones that will exit out at a true.
if = { # Direct limiting is only supported in effect scopes.
limit = {
has_country_flag = example_flag
}
add_to_temp_variable = { flag_counter = 1 } # Assumed to be zero if unset
}
}
check_variable = { flag_counter > 9 }
}
country_event = example.0 # The event fires if at least 10 countries have the example_flag flag.
}
Additionally, it is common for a variable to be a counter of something within a mechanic. For example, let CAN_beavers be a counter of beavers within the country.
When using variables in this sense, it is better to use scripted effects to modify them, in order to make changes to the variable easier. For example, a small gain in beavers could be the following:
CAN_beavers_small_add = {
custom_effect_tooltip = CAN_beavers_small_add_tt # Tooltip for the player to be aware.
add_to_variable = { CAN_beavers = 100 } # Adds 100 beavers.
}
However, if 100 seems like too little, the scripted effect can be changed and it'll immediately apply the changes every single time that scripted effect was used without needing to find them manually. These effects may also share a single 'recalculating' scripted effect in common. This can be used to clamp the variable between a minimum and a maximum, to have an instant effect as soon as some variable value is reached, or to have another variable 'tied' to the value to be kept at an exact or a dynamic ratio. For example, these scripted effects can be used with the same CAN_beavers example:
CAN_beavers_calibrate = {
clamp_variable = { # The variable will be kept between these levels by calling this each time the variable is changed.
var = CAN_beavers
min = 0
max = 2000
}
set_variable = { CAN_beavers_modifier = CAN_beavers }
divide_variable = { CAN_beavers_modifier = 1000 } # Another variable tied to the base value, as long as the scripted effect is called upon each change of CAN_beavers.
if = {
limit = {
check_variable = { CAN_beavers = 0 }
}
country_event = CAN_beavers_extinction.0 # The event gets fired as soon as CAN_beavers hits 0.
}
}
CAN_beavers_small_add = { # Same as before, but with calling the previous effect
custom_effect_tooltip = CAN_beavers_small_add_tt
add_to_variable = { CAN_beavers = 100 }
CAN_beavers_calibrate = yes
}
CAN_beavers_small_remove = { # Another example of a variable-modifying effect
custom_effect_tooltip = CAN_beavers_small_remove_tt
add_to_variable = { CAN_beavers = -100 } # 'subtract_from_variable = { CAN_beavers = 100 }' also works.
CAN_beavers_calibrate = yes
}
After creating these scripted effects, these can be used within any effect block to modify the variable at will. Showing its value in localisation to the player would also be helpful, such as within a decision category or in scripted GUI. Variables cannot be used within idea modifiers directly, dynamic modifiers can be used instead.
Remember that variables are not necessarily used as numbers only. For example, the simplest way to make the current ideology group to change to the one that's the most popular (aside from the ruling party) would be a set_politics = { ruling_party = highest_party_ideology@exclude_ruling_party }. Similarly, some event target-type variables can be used to cut down on code, such as transfer_state = GER.capital immediately transferring the capital of GER to the current scope.
MTTH variables
MTTH variables allow to dynamically create a MTTH block to be used as a variable. These are stored within /Hearts of Iron IV/common/mtth/*.txt files, where each MTTH variable is a separate block, the name of which gets taken as the MTTH variable.
As per the name, the MTTH variables serve as a MTTH block, so everything that applies to MTTH blocks applies here: The starting base is defined with factor or base and then each modifier = { ... } begin a trigger block needed to be fulfilled for the add (for adding) or/and factor (for multiplying) within to be applied.
For example, the following is an example of a /Hearts of Iron IV/common/mtth/*.txt file:
my_mtth_variable_1 = {
base = 10
modifier = {
factor = 10
is_major = yes
}
modifier = {
add = -10
tag = FRA
}
}
my_mtth_variable_2 = {
base = other_variable
factor = 0.5
add = 10
}
This can be called the same way as a game variable, but somewhat differently: set_variable = { my_var = mtth:my_mtth_variable_1 }. This will check the MTTH block for the scope where it's checked and return the total result as a variable.
Debugging variables
There are the following arguments that can be used in trigger or effect blocks:
| Name | Parameters | Examples | Description | Notes |
|---|---|---|---|---|
| log | <string>What to write in the log. |
log = "Current value of myVar in [THIS.GetName]: [?myVar]" |
Creates an entry in the /Hearts of Iron IV/logs/game.log file in the user directory and, if console is open and debug mode is turned on, in console as well. | While it nominally has nothing to do with variables, its most common use is for variables. |
| print_variables | file = <string>The name of the file, not counting the file extension. Defaults to "variable_dump".
|
print_variables = {
file = my_file
text = "These variables are printed at [GetDateText]"
append = yes
print_global = yes
}
print_variables = {
file = my_file_2
var_list = { temp1 temp2 temp3 }
}
|
Dumps the specified variables from the current scope and optionally the global scope into a log file with the specified name. | The log will be within /Hearts of Iron IV/logs/variable_dumps/ in the user directory. |
Additionally, the following console commands exist for variables. In console commands, the 'current scope' is what is currently selected: the country opened in diplomacy, the state selected, the unit leader that's selected. If left out, assumes to be the player country.
| Name | Parameters | Examples | Description |
|---|---|---|---|
| set_var | <variable>The variable to get the value of.
|
set_var my_variable 10 |
Changes the value of the variable within the specified scope. |
| get_var | <variable>The variable to get the value of. |
get_var my_variable |
Prints the value of the variable in console. |
| list_vars | <scope>Optional. Changes the scope from the currently-selected scope to what's specified.
|
list_vars |
Lists the variables and their values as within the currently-selected scope. |
Token-valued variables
When one uses a literal of the form token:some_tokenizable_value, what is actually returned is an integer variable (commonly with a large value), with an internal flag set so that it is interpreted as an index into a central table of token strings that exists within the game's memory. This can be placed into a variable and passed around freely, it can be compared for equality to other token variables, and it can even be treated as a numeric in arithmetic even if usages for such cases are rare if nonexistent. Variables that have the token flag set can be distinguished in the output of the list_vars console command by dint of being automatically translated into their underlying raw-token strings. For example, some_var_name = token:some_tokenizable_value (27012).
When the variable contains a token value, it is possible to use the GetTokenKey localisation function (such as [?some_var_with_token_value.GetTokenKey]) to get the token string value of the variable, token: prefix not included. This is useful for pasting in meta-effects and meta-triggers, however note that the token: prefix is still required if using it within the set_(temp_)variable operator. With some token-valued variables (specifically, those backed by named database objects of a tokenizable datatype), it is possible to use GetTokenLocalizedKey to retrieve the value of the localisation key with the same name as the token itself. This can be used to produce and/or define human-readable names, but it can also be taken advantage of to pass around arbitrary localisation values.
At present (1.12), known tokenizable datatypes include (but are probably not limited to):
- Ideas: These are generally the most flexible tokenizable datatype to use for a token that represents some arbitrary value by using a dummy idea. They can also carry an effectual payload in their
on_addclauses, which can be used to pass around effects, or better yet, to return a set of variables encoding information relevant to the token value. - Everything listed in /Hearts of Iron IV/common/script_enums.txt
- Ideologies/Ideology groups
- Technologies
- Equipment types - Sometimes this is a bit inconsistent with regards to the archetype/non-archetype distinction, so be wary.
- Operations
- Characters/Unit leaders: These are finicky in the game's core. When a character is promoted to a unit leader position, all tokenizations of that character's token will begin to return a different value, representing the token for the unit leader with the same identifier, which is linked to, but not the same as, the original character. The unit leader version of the token returns the same
GetTokenKeyandGetTokenLocalizedKey, but it is not numerically equal to the character version of the token. This can come into play if code compares the equality of two character-pointing variables. - Decisions
- Buildings
Advanced use of tokens
Using tokenizable values in variables is the key to a number of advanced techniques that enable relatively seamless abstraction and metaprogramming, with a minimum of scripted-localisation boilerplate code. These techniques are, however, difficult to learn how to apply and can be unintuitive for those not already experienced. Therefore, caution is advised.
It is often useful to define related dummy tokenizable database entries, especially ideas, to represent arbitrary (possibly enumerable) custom datatypes. In most cases, ideas are preferable, however there can be uses for other token types, such as technologies if the code is to implement something that can't be done with a regular idea. The reason for idea preference is little to no downstream effects simply from existing, ease to define in bulk with minimal syntactic overhead, and ease to separate different custom datatypes by using custom idea categories and by placing the definitions for different custom datatypes in different files within /Hearts of Iron IV/common/ideas/. Decisions or technologies are common alternatives for custom datatypes with different usages, but generally datatypes other than these have too much downstream baggage (i.e. their very existence has consequences elsewhere, such as custom building types appearing automatically in certain UIs) to be worth using for dummy values.
Using a systematic naming scheme, custom tokenizable datatypes can also convey multiple related localisation keys, similarly to the approach that the base game does for country naming with separate TAG, TAG_DEF, and TAG_ADJ keys. An example of that would be creating an idea foo_bar to act as the key identifier of the custom data value, whose localisation value carries the human-readable name of the data value, and another idea foo_bar_description (NOT foo_bar_desc, this collides with the localisation key generated for foo_bar) to carry the localisation value for the description that would be associated with the data value identified by foo_bar. This description localisation can be accessed with a meta-effect or meta-trigger (including in scripted localisation), such as set_temp_variable = { description_var = token:[IDEA_TOKEN]_description } (where IDEA_TOKEN = "[?idea_var_name.GetTokenKey]"). This allows accessing [?description_var.GetTokenLocalizedKey] in localisation where description_var is visible, such as the localization_key following the scripted localisation trigger block where the pasting meta-trigger is called.
As far more advanced usage, it is possible to rig up the dummy tokenizable values with arbitrary localisation payloads that carry fragments of Clausewitz code which can then be pasted together in meta-effects (or triggers) to approximate true token string manipulation or at least concatenation, as there's presently no way to split strings, token or otherwise. This is probably most useful for encoding a set of suffixes that can be applied to an idea token to dynamically navigate within the custom datatype's naming scheme. For example, if the mod has a custom datatype representing positions within a government such as the Secretary of State and the Attorney General, such that it might have a base idea position_attorney_general, a corresponding description idea (suffixed with _description), a singular name idea (suffixed with _singular, carrying the name of the data value in singular form, like "Attorney General"), and a plural name idea (suffixed with _plural, carrying the name in plural form, like "Attorneys General"), it is possible to select which name to use by having a dummy idea called enum_position_name_singular with the localisation value "_singular", and another called enum_position_name_plural with the localisation value "_plural". After that, the mod may pass one of the enum_position ideas in a variable and then paste its GetTokenLocalizedKey after the GetTokenKey of the base idea in a meta-effect/trigger to produce either token:position_attorney_general_singular or token:position_attorney_general_plural. This is a contrived example, and is also possible to be done using a scripted localisation system with hard-coded entries to access the singular vs. plural ideas, but this approach has far more use in more complex systems where creating a scripted localisation file can prove to be far too bulky.
From 1.12 onwards, anything defined in /Hearts of Iron IV/common/script_enums.txt can be freely tokenized, even if defined in a totally custom enumeration block, seperate from the ones hard-coded into the game. It is therefore theoretically possible to define arbitrary tokens of a custom enum type in this file. However, for compatibility reasons, using script_enums for custom enumeration types should be avoided, as this will ensure that the mod will not be compatible with any other mod that overwrites that file, no matter which mod gets priority on the file. As before, it's preferable to have a custom idea category with a set of dummy ideas in their own file that will not be overridden by other mods representing the values the custom enum can take on. This pattern is a useful replacement for passing around arbitrary integers that have some enumerable meaning when interpreted by code, especially if those integers are interpreted to yield names in scripted localisation, in which case this pattern can substantially remove the need for scripted localisation boilerplate by allowing defining the localised name for each enum member directly in a localisation file, as similarly to defining the localised name for an idea.
Technically, any raw token used in the language can actually be tokenized: for instance, token:set_stability (that is, a token literal of the name of the set_stability effect) is perfectly valid, and yields a token for which GetTokenKey and GetTokenLocalizedKey both return set_stability. However, this is rarely useful (especially since it does not apply to scripted effect and trigger names), and arguably counts as a bug; it mostly just provides an interesting peek into the internals of the tokenization system, indicating that it most likely delegates to a pre-existing string de-duplication system built into the Clausewitz engine.
Modifier tokens
- This section is transposed from Modifiers § Modifier definitions
Modifier definitions allow the creation of a custom modifier, which can be accessed as a variable when you wish to use it. After being defined, they function entirely like a new variable, being possible to read as a variable with the same modifier@modifier_name procedure. They will not have any effect by default and function only as a way to change the variable's value in an additive way with modifier blocks.
Each modifier token is defined within /Hearts of Iron IV/common/modifier_definitions/*.txt files as a separate code block, where the name of the code block serves as the ID of the modifier definition. There are the following arguments that can go inside of it:
color_type = gooddecides the colour of the modifier's value itself. There are three values,good,bad, andneutral.neutralis permamently yellow, whilegoodturns the positive values green and negative values red.badis the reversal ofgood.value_type = percentagedecides the way the number will show up in the tooltip. There are the following values this argument can be set to:numberwill make the exact value of the modifier show up. 0.02 will show up like "Modifier definition: 0.02".percentagewill make the modifier show up as a percentage on the scale from 0 to 1. 0.2 will show up like "Modifier token: 20%".percentage_in_hundredwill make the modifier show up as a percentage on the scale from 0 to 100. 10 will show up like "Modifier token: 10%".yes_noshows up as a boolean: anything larger than 1 will shows up asyes, while 0 will show up asno.
precision = 1decides how many numbers will be shown after the period in the tooltip. For example, if it is set to 1, the tooltip will show 0.341 as if it was 0.3. Note that the game inherently does not support more than 3 decimal numbers, so it cannot be larger than 3.postfixdecides what will be added after the value of the modifier in the tooltip. Allowed values are 'none' (Default), 'days', 'hours', and 'daily'.categorydecides on the category of the modifier. By default, the category is 'all', which makes it be in every single category. Certain tooltips will only show modifiers if they belong to a certain category. It is possible to set multiple categories for the same modifier definition by defining them one after another.
- The allowed values are 'none', 'all', 'country', 'state', 'unit_leader', 'army', 'naval', 'air', 'peace', 'politics', 'ai', 'defensive', 'aggressive', 'war_production', 'military_advancements', 'military_equipment', 'autonomy', 'government_in_exile', and 'intelligence_agency'.
The modifier definition's ID is also used as the localisation key needed to change the name of the modifier depending on the currently turned on language.
Examples
modifier_definition_example = {
color_type = good
value_type = number
precision = 1
postfix = daily
category = country
category = state
}
modifier_definition_example_2 = {
color_type = bad
value_type = percentage
}
Using in variables
The function of modifier definitions is to modify the value of a game variable, which can be read by other variables. You can set a variable to be equal to the sum of all values of the same modifier token in the current scope by doing set_variable = { var_name = modifier@modifier_token_name }. This example will set var_name to be equal to the total value of modifier_token_name.
Note that, unlike countries and states, unit leaders use leader_modifier@modifier_definition_name or unit_modifier@modifier_definition_name in their scopes.
Example usage of making a modifier token create civilian factories in random core states monthly, in any on action file:
| Example |
|---|
on_actions = {
on_monthly = {
effect = {
if = {
limit = {
check_variable = { modifier@modifier_definition_example > 0 }
}
for_loop_effect = {
start = 0
end = modifier@modifier_definition_example
random_owned_controlled_state = {
limit = {
is_core_of = ROOT
free_building_slots = {
building = industrial_complex
size > 0
include_locked = no
}
}
add_building_construction = {
type = industrial_complex
level = 1
instant_build = yes
}
}
}
}
}
}
}

Arrays
Arrays are similar to variables, but they instead store a collection of variables.
An array in the game is structured with indexes starting from 0. arrayname^0 as a variable refers to the first item of arrayname, arrayname^1 refers to the second item in the array, and so on. In order to obtain the total amount of items within the given array, arrayname^num is used. An array is assumed to have no elements by default, if not already created, with add_to_array or add_to_temp_array usually being used to create an array.
Temporary and regular arrays exist, with the same distinction between them as in variables: temp arrays can be set and modified in triggers and effects, are unscoped, and cleared after the effect/trigger block ends; regular arrays can only be set or modified in effects, are linked to a specific scope, and persist forever until cleared manually.
A single element of an array is considered a variable in every regard: set_variable = { arrayname^0 = 10 } will set the first element to be equal to 10 (with set_temp_variable used for temporary arrays), check_variable = { arrayname^0 > 10 } is also valid syntax, and [?arrayname^0] will print the value of the element in localisation. However, the element must already exist for it to be edited. There is no simple way to print an entire array in localisation, however a recursive scripted localisation can be used, which modifies the value of a temporary variable by one until hitting the array's size each time that it's used.
Arguments
The following arguments exist for arrays. Similarly to variables, temporary versions exist by replacing array with temp_array.
| Name | Parameters | Examples | Description | Notes |
|---|---|---|---|---|
| add_to_array | array = <array>The array to modify.
|
add_to_array = {
array = global.my_countries
value = THIS.id
}
add_to_temp_array = { temp_states = THIS }
|
Adds an element to the array either at the specified index, defaulting to the end otherwise. | Shortened version exists with add_to_array = { <array> = <value> }.
|
| remove_from_array | array = <array>The array to modify.
|
remove_from_array = {
array = global.my_countries
index = 0
}
remove_from_temp_array = { temp_states = THIS }
|
Removes an element from the array with the specified value or index. | Shortened version exists with remove_from_array = { <array> = <value> }. If neither value nor index are specified, then the last element is deleted.
|
| clear_array | <array>The array to clear. |
clear_array = global.my_countries clear_temp_array = temp_states |
Clears the array, removing every element inside. | |
| resize_array | array = <array>The array to modify.
|
resize_array = {
array = global.countries_by_states
value = 10
size = global.countries^num
}
resize_temp_array = { temp_states = 20 }
|
Resizes the array, removing or adding elements in the end if necessary. | Shortened version exists with resize_array = { <array> = <size> }.
|
| find_highest_in_array | array = <array>The array to modify.
|
find_highest_in_array = {
array = global.countries_by_states
value = temp_largest_country
index = temp_country_index
}
|
Finds the largest value in the array and assigns its value and index to a temporary variable. | Either value or index are optional to specify. |
| find_lowest_in_array | array = <array>The array to modify.
|
find_lowest_in_array = {
array = global.countries_by_states
value = temp_largest_country
index = temp_country_index
}
|
Finds the smallest value in the array and assigns its value and index to a temporary variable. | Either value or index are optional to specify. |
Meanwhile, the following triggers exist that are array-related. As with variables, these are the exact same for temporary and regular variables.
| Name | Parameters | Examples | Description | Notes |
|---|---|---|---|---|
| is_in_array | array = <array>The array to check.
|
is_in_array = {
array = global.my_countries
value = THIS.id
}
is_in_array = { temp_states = THIS }
|
Checks if any value within the array is the same as the specified value. | Shortened version exists with is_in_array = { <array> = <value> }.
|
| any_of | array = <array>The array to check.
|
any_of = {
array = temp_numbers
value = v
index = i
multiply_temp_variable = { v = i }
check_variable = { v > political_power } # Checks if the value multiplied by the index is larger than the political power of the country this is checked in.
}
|
Checks if any value within the array fulfills the triggers, halting and returning true if that's the case. | The scope does not change from the one this is checked in by default, requiring one of scopes. |
| any_of_scopes | array = <array>The array to check.
|
any_of_scopes = {
array = global.majors
tooltip = has_more_states_than_any_other_major_tt
NOT = { tag = PREV }
check_variable = { num_owned_controlled_states > PREV.num_owned_controlled_states }
}
|
Checks if any value within the array fulfills the triggers, halting and returning true if that's the case, scoping into each element in the array. | Appending _NOT to the tooltip's key (such as has_more_states_than_any_other_major_tt_NOT in the example) results in the localisation key used if this any_of_scopes is put inside of NOT = { ... }. Since this changes scopes, PREV would, unless there's deeper scoping, refer to the scope this trigger is checked in.
|
| all_of | array = <array>The array to check.
|
all_of = {
array = temp_numbers
value = v
index = i
multiply_temp_variable = { v = i }
check_variable = { v > political_power } # Checks if the value multiplied by the index is larger than the political power of the country this is checked in.
}
|
Checks if every value within the array fulfills the triggers, halting and returning false if any one doesn't. | The scope does not change from the one this is checked in by default, requiring one of scopes. |
| all_of_scopes | array = <array>The array to check.
|
all_of_scopes = {
array = global.majors
tooltip = has_more_states_than_every_other_major_tt
OR = {
tag = PREV
check_variable = { num_owned_controlled_states < PREV.num_owned_controlled_states }
}
}
|
Checks if every value within the array fulfills the triggers, halting and returning false if any one doesn't, scoping into each element in the array. | Appending _NOT to the tooltip's key (such as has_more_states_than_every_other_major_tt_NOT in the example) results in the localisation key used if this any_of_scopes is put inside of NOT = { ... }. Since this changes scopes, PREV would, unless there's deeper scoping, refer to the scope this trigger is checked in.
|
The following effects also exist in addition used, with arrays. While some are nominally unrelated to arrays, they are often used in conjunction.
| Name | Parameters | Examples | Description | Notes |
|---|---|---|---|---|
| for_each_loop | array = <array>The array to check.

add_stability = v
}
10 = {
divide_temp_variable = { v = 100 }
add_war_support = v
}
}
}
|
Runs an effect once for every element in the array. | The scope does not change from the one this is checked in by default, requiring one of scopes. |
| for_each_scope_loop | array = <array>The array to check.
|
for_each_scope_loop = {
array = global.majors
if = {
limit = {

}
random_owned_controlled_state = {
transfer_state_to = PREV.PREV
}
}
}
|
Runs the effects for every scope within the array. | Equivalent to a every_<...> effect scope type, with additional break. Since this changes scopes, PREV would, unless there's deeper scoping, refer to the scope the effect is executed in.
|
| random_scope_in_array | array = <array>The array to check.
|
random_scope_in_array = {
array = global.countries
break = break
limit = {
is_dynamic_country = no
exists = no
any_state = {
is_core_of = PREV # Is core of the currently-checked country
}
}
random_core_state = {
transfer_state_to = PREV # Transfers to the currently-selected country.
}
}
|
Runs the effects for a random scope within the array. | Equivalent to a random_<...> effect scope type, with additional break. Since this changes scopes, PREV would, unless there's deeper scoping, refer to the scope this effect is executed in.
|
| while_loop_effect | limit = { <triggers> }An AND trigger block deciding when the effect would repeat.
|
while_loop_effect = {
limit = {
any_country = {
num_owned_controlled_states > 10
}
}
random_country = {
limit = {
num_owned_controlled_states > 10
}
random_other_country = {
limit = {
num_owned_controlled_states < 10
}
PREV = {
random_owned_controlled_state = {
transfer_state_to = PREV.PREV
}
}
}
}
}
|
Runs the effects as long as the limit is fulfilled. | The limit is only checked at the beginning and once the effect block is executed. Can't run for more than 1000 times by default[5]. |
| for_loop_effect | start = <decimal>/<variable>The value at which the evaluation starts. Default to 0.
|
for_loop_effect = {
end = 4
value = temp
if = {
limit = {
NOT = {
count_triggers = {
amount = 2
check_variable = { temparr^temp < temparr^0 }
check_variable = { temparr^temp < temparr^1 }
check_variable = { temparr^temp < temparr^2 }
check_variable = { temparr^temp < temparr^3 }
}
}
}
add_to_array = { potential_max = temp }
}
}
|
Runs the effects as long as the limit is fulfilled. | The limit is only checked at the beginning and once the effect block is executed. Can't run for more than 1000 times by default[5]. Comparison types are the same as used in check_variable. |
Scorers
Scorers are defined within /Hearts of Iron IV/common/scorers/country/*.txt files, serving as a sorted list of targeted countries, based on how well they did in the specified MTTH block. The scorer has the primary country which the scorer is used for and targeted countries.
Each scorer is a separate block within the file, with the name of the block being the name of the scorer. The scorer then has the targets = { ... } block that encompasses everything else about the scorer.
Scorers target countries similarly to targeted decisions but with differences, with the following arguments being used within of targets = { ... }:
targets = { TAG, TAG }- A list of country tags, including other dual scopes such as overlord, that can be targeted by this scorer. Unlike targeted decisions, this seems to be comma-separated.target_array = global.majors- The array to target. The default scope is the primary country.target_root_trigger = { ... }- The trigger block which the primary country must fulfill for the target to work.target_trigger = { ... }- The trigger block that target country must fulfill for the target to work.targets_dynamic = yes- If set, makes the dynamic countries possible targets. Defaults to no.target_non_existing = yes- If set, makes non-existing countries possible targets. Defaults to no.score = { ... }- This is the MTTH block itself that ranks the countries in the list. By default, THIS (the default scope) is the target, FROM is the primary country initialising the check.
For example, the following is a scorer that sorts every major country depending on the amount of states they own:
majors_owned_states = {
targets = {
target_array = global.majors # Global is not the default scope, scope into it.
targets_dynamic = yes
target_non_existing = yes # As implausible as this is, this is likely technically possible by using the set_major effect.
score = {
factor = num_owned_states
}
}
}
After defining a scorer, there is the way to use it: an argument, similar to arrays and variables. Similarly to them, regular and temporary versions exist, which decides whether the variable/array it's writing to is regular or temporary. Both can only be used inside of country scope. Regular versions can only be used in effects, and temporary versions can be used in effects and triggers.
| Name | Parameters | Examples | Description | Notes |
|---|---|---|---|---|
| get_highest_scored_country | scorer = <scorer>The scorer to use.
|
get_highest_scored_country = {
var = majors_owned_states
value = largest_major
}
get_highest_scored_country_temp = {
var = majors_owned_states
value = largest_major
}
|
Sets the specified variable to be the highest-scoring country within the scorer, as checked for the country where this is used. | |
| get_sorted_scored_countries | scorer = <scorer>The scorer to use.
|
get_sorted_scored_countries = {
scorer = majors_owned_states
array = major_owners
values = major_states
}
get_sorted_scored_countries_temp = {
scorer = majors_owned_states
array = major_owners
values = major_states
}
|
Creates two arrays of countries and their corresponding values, sorted in the ascending order. | Values with the same index are connected: in the example, major_owners^0 is the country that got major_states^0 points in the majors_owned_states scorer. |
Example
Scorers can be helpful to create a sorted list of scopes by a certain element, such as political power. For example, the following can be used to find the countries with the most infantry equipment and send an event to the top three that are at peace with ROOT:
Within the scorer file:
infantry_equipment_sort = {
target_array = global.countries
targets_dynamic = yes
score = {
factor = num_equipment@infantry_equipment
}
}
Within an effect block:
ROOT = {
get_sorted_scored_countries_temp = {
scorer = infantry_equipment_sort
array = temp_inf_eq_countries
}
for_each_scope_loop = {
array = temp_inf_eq_countries
break = break
if = {
limit = {
NOT = {
tag = ROOT
has_war_with = ROOT
}
}
add_to_temp_variable = { v = 1 }
country_event = equipment_please.0
}
if = {
limit = {
check_variable = { v = 3 }
}
set_temp_variable = { break = 1 }
}
}
}
Game variables
| File:Ambox outdated info.png | 这部分内容可能已不适合当前版本，最后更新于1.13。 |
Game variables are read-only variables that are used to read certain aspects of the game, such as the current political power that the player has. These cannot be modified using any variable-modifying argument, but they can serve as the value within them (such as add_to_temp_variable = { temp = GER.army_experience } adding the amount of army experience that GER has to the temp temporary variable). Some are targeted, requiring one more argument in the target's place. For example, modifier has a modifier token as the target, so it would be used as set_temp_variable = { temp = modifier@consumer_goods_factor }, where consumer_goods_factor is the name of the modifier used as the argument.
Remember that to get global-scoped game variables, it is necessary to scope into global as global.year rather than leaving out the scope. A list of game variables can be found within /Hearts of Iron IV/documentation/dynamic_variables_documentation. A large portion of purely numeric Triggers also have corresponding game variables that are not mentioned in the documentation. The following game variables exist in the game (Some duplicates are omitted):

|---|---|---|
| year | None. | The current year, such as 1936. |
| date | None. | The ID of the current date. This can be localised in a multitude of different ways, using the localisation functions beginning with GetDateString. This variable functions by having one game hour be 0.001, with 0 of the variable corresponding to the date 1st January -5000, 1:00.
|
| num_days | None. | The amount of days passed since the start of year 0. The value on the 1st of January 1936 is 706640. |
