Effects (also known as Commands) are used in order to affect the game dynamically from within a specific scope. They are a one-time change to the current condition of the game, without the ability to have a lasting effect. Instead, modifiers are used to have a continuous, everlasting effect on the game's condition that can be represented with a number. Effect blocks cannot be used to apply modifiers directly, however they can add something that can apply modifiers, most commonly with add_ideas.

Effects are used throughout the game in numerous scopes, most commonly edited effect blocks are national focus rewards, event options and decision effects.

Note that certain effects may take a value from a variable, i.e. add_manpower = var:my_var This is noted by <variable> in an effect's parameters. See Variables for information on the variable effects.

The list of effects may be outdated. A complete, but unsorted, list of effects can be found in /Hearts of Iron IV/documentation/effects_documentation.html or /Hearts of Iron IV/documentation/effects_documentation.md.

Scopes

主条目：Scopes

Scopes serve as special effect types that modify the entity that serves as the context for the effects being executed, such as GER = { add_political_power = 150 } adding 150 political power to 德意志国.

Effect scopes

NOTE: Some of these scopes may have no countries/states that match the criteria

Effects with scopes

Effects that change the scope include the following:

• start_civil_war, which changes it to the rebelling dynamic country.
• create_dynamic_country, which changes it to the newly-created dynamic country.

Dual scopes

The following scopes can be used either as effect or trigger scopes; some can also be used as the right side of some effects and triggers as a target. If usage as a target is possible, it's marked within the table.

Several dual scopes may have a scope that varies depending on where it's used, such as variables, which can be set to anything.

Dual scopes:

Name	Usage	Target type	Example	Description	Usable as target	Version Added
TAG	Always usable	Country scope	SOV = { country_event = my_event.1 }	The country defined by the tag or tag alias. Tag aliases are defined in /Hearts of Iron IV/common/country_tag_aliases, as a way to refer to a specific country (such as a side in a civil war) in addition to its actual tag. If the country with the exact tag doesn't exist, but a dynamic country originating from the specified tag does, the scope will refer to the dynamic country.	✓	1.0
<state_id>	Always usable	State scope	123 = { transfer_state_to = SCO }	The state defined by this id.	✓	1.0
<character>	not within Character scope	Character scope	ENG_theodore_makhno = { set_nationality = UKR }	On game versions prior to 1.12.8, the character must be already recruited by the country this is scoped from.	✓	1.11
mio:<MIO>	Always usable	MIO scope	mio:AST_cockatoo_doe_organization = { … }	The MIO identified by that ID as defined within the /Hearts of Iron IV/common/military_industrial_organization/organizations/*.txt file.	✓	1.13
ROOT	Always usable	Depends on usage	ENG = { FRA = { GER = { declare_war_on = { target = ROOT type = annex_everything } } } } #GER declares war on ENG (if there is no scope before ENG)	Targets the root node of the block, an inherent property of each block. Most commonly, this is the default scope: for example, ROOT within a national focus will always refer to the country doing the focus and ROOT within a event will always refer to the country getting the event. However, some blocks do distinguish between the default scope and ROOT, such as certain scripted GUI contexts or certain on actions. If a block doesn't have ROOT defined (such as on_startup in on actions), then it is impossible to use it.	✓	1.0
THIS	Always usable	Depends on usage	set_temp_variable = { target_country = THIS }	Targets the current scope where it's used. For example, when used in every_state, it will refer to the state that's currently being evaluated. Primarily useful for variables (as in the example, where omitting it wouldn't work) or for built-in localisation commands, where some scope must be specified. More rarely, this may help with scope manipulation when using PREV. Since omitting it makes no difference in how the code gets interpreted, there is little to no usage outside of these cases.	✓	1.0
PREV	Always usable	Depends on usage	FRA = { random_country = { GER = { declare_war_on = { target = PREV type = annex_everything } } } } #Germany declares war on random_country	Targets the scope that the current scope is contained in. Can have additional applications where the assumed default scope differs from the ROOT, such as in state events or some on_actions. Can be chained indefinitely as PREV.PREV. Commonly results in broken-looking tooltips: what's shown to the player doesn't always correlate with reality. See also: PREV usage.	✓	1.0
FROM	Always usable	Depends on usage	declare_war_on = { target = FROM type = annex_everything } FROM = { load_oob = defend_ourselves }	Can be chained indefinitely as FROM.FROM. Used to target various hardcoded scopes inherent to the block, often a secondary scope in addition to ROOT. For example: In events, this refers to the country that sent the event (i.e. if the event was fired using an effect, then it's the ROOT scope where it was fired). In targeted decisions or diplomacy scripted triggers, this refers to the scope that is targeted.	✓	1.0
overlord	Within country scope only	Country scope	overlord = { … }	The overlord of the country if it is a subject. Subject to the 'invalid event target' error.	X	1.3
faction_leader	Within country scope only	Country scope	faction_leader = { add_to_faction = FROM }	Faction leader of the faction the country is a part of. Subject to the 'invalid event target' error.	X	1.10.1
owner	Within state, character, or combatant scope only	Country scope	owner = { add_ideas = owns_this_state }	In state scope, the country that owns the state. In combatant scope, the country that owns the divisions. In character scope, the country that has recruited the character. Subject to the 'invalid event target' error when used for a state.	X	1.0
controller	Within state scope only	Country scope	controller = { ROOT = { create_wargoal = { target = PREV type = take_state_focus generator = { 123 } } } }	The controller of the current state. Subject to the 'invalid event target' error.	X	1.0
capital_scope	Within country scope only	State scope	capital_scope = { … }	The state where the capital of the current country is located in. Subject to the 'invalid event target' error in rare cases.	X	1.0
event_target:<event_target_key>	Always usable	Depends on usage	event_target:my_event_target = { … }	Saved event target or global event target, with no space after the colon. Subject to the 'invalid event target' error.	✓	1.0
var:<variable>	Always usable	Depends on usage	var:my_variable = { … } add_to_faction = my_variable or add_to_faction = var:my_variable	Variable set to a scope. When used as a target rather than a scope, the var: can be omitted in most cases.	✓	1.5

Any scope

Can be used in country, state or character scopes.

Variables

This section is transcluded from Data structures § 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.

Variable-related arguments:

Name	Parameters	Examples	Description	Notes
set_variable	var = <variable> The variable to modify or create. value = <decimal>/<variable> The value to set the variable to. tooltip = localisation_keyLocalisation used by the operation. Optional.	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. min = <decimal> The minimum possible value, defaults to 0. max = <decimal> The maximum possible value, defaults to 1. integer = <bool> Sets if the variable must be an integer or if it can be decimal. Defaults to false.	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.
add_to_variable	var = <variable> The variable to add to. value = <decimal>/<variable> The value to add to the variable. tooltip = localisation_keyLocalisation used by the operation. Optional.	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. value = <decimal>/<variable> The value to subtract from the variable. tooltip = localisation_keyLocalisation used by the operation. Optional.	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. value = <decimal>/<variable> The value to multiply the variable by. tooltip = localisation_keyLocalisation used by the operation. Optional.	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. value = <decimal>/<variable> The value to divide the variable by. tooltip = localisation_keyLocalisation used by the operation. Optional.	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. value = <decimal>/<variable> The value to modulo the variable by. tooltip = localisation_keyLocalisation used by the operation. Optional.	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. min = <decimal>/<variable> The minimum value of the variable after the clamp. max = <decimal>/<variable> The maximum value of the variable after the 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.

The reserve_dynamic_country effect can be used if the dynamic country does not yet exist in order to ensure that it does not get overwritten by other creations of dynamic countries. If this is not done, the dynamic country will immediately stop existing if no states are transferred in the same scope. Every state of the original country immediately gets set as a dynamic country's core: if that's unneeded, the cores would need to be removed after creation.	1.9

Flow control

These scopes are used within effect scopes to control the execution of effects.

If statements

An if statement allows an execution of effects to only be done if certain triggers are met. Conditional statements are represented with the if = { ... } effect. limit = { ... } inside of the if statement serves as a trigger block that defines the conditions when it should be executed, and everything else directly inside of if = { ... } is interpreted as the effects that should be executed if the condition is true.

For example, the following will add 10% 稳定度 to the country this is executed on if it has positive 政治点数 and below 90% stability:

if = {
    limit = {
        has_political_power > 0
        stability < 0.9
    }
    add_stability = 0.1
}

If the limit is not met, then none of the effects inside will be executed. If it is, then each one will be. If the limit is omitted, it defaults to being always true.

The effects must be inside of the if statement to be tied to the limit. For example, this will always give 100 政治点数, regardless of what country is played:

if = {
    limit = { tag = BHR }
}                         # Closes if = { ... }. Since no effects are inside, this means that the if statement does absolutely nothing
add_political_power = 100 # Outside of if = { ... }, so it will always give 100 political power, even if not playing as BHR

Optionally, else_if = { ... } (with limit = { ... } serving in a similar fashion) and else = { ... } can be added. If the initial limit within if = { ... } is false, it moves on to the next else_if = { ... }, checking the limit there. If the limit there is false, then it moves on to the next one, until hitting an end or an else = { ... }.
Two variants exist: nested and unnested. In the first case, the else_if or else is put directly inside of the preceding if or else_if, while in the second case it's put right after. In case of overlap, unnested if statements are preferred. Here is an example using unnested if statements:

if = {
    limit = {
        stability < 0.3 # If stability is below 30%, add 30%.
    }
    add_stability = 0.3
}
else_if = {
    limit = {
        stability < 0.6 # Otherwise, if it's below 60% (i.e. 30-59%), add 20%
    }
    add_stability = 0.2
}
else = {
    add_stability = 0.1 # If there's 60-100% stability, add 10%
}

Within the tooltip, only effects that would be executed are shown. The effects within an unfulfilled if statement (or an else/else_if that's not read due to the if statement being met) will be hidden from the player, and so will the trigger. In order to avoid player confusion, custom effect tooltips can be used to tell the player what this effect block would do, such as being used within an else.

Random effects

If you want an effect to have a random chance to be done or have nothing happen otherwise, the random = { ... } block is the simplest way to accomplish that:

random = {
    chance = 80
    add_stability = 0.4
    add_war_support = 0.3
}

This in particular will have an 80% chance to add 40% stability and 30% war support and, accordingly, a 20% chance to do nothing. The chance here is on the scale from 0 to 100.

If you want the game to choose between effect blocks, random_list can be used instead. For example, if you wanted an effect to randomly given the player one out of four bonuses, you'd do the following:

random_list = {
    10 = {
        add_stability = 0.5
    }
    10 = {
        add_manpower = 10000
    }
    10 = {
        add_war_support = 0.5
    }
    10 = {
        army_experience = 100
    }
}

The number is not the chance, but the weight for each option, as they don't have to add up to 100 or any number. An option with the weight of 20 is twice as likely to be picked as the option with the chance of 10, for instance. In total, the probability for an option to be picked is equal to the weight of the option divided by the sum of all weights.

It is also possible to use modifiers (akin to MTTH blocks) to affect the weight of each possible random effect or to use variables as chances.

random_list = {
    30 = {
        modifier = {
            factor = 1.3
            has_country_flag = inward_perfect_flag
        }
        add_stability = 0.5
    }
    25 = {
        add_manpower = 10000
    }
    20 = {
        add_war_support = 0.5
    }
    my_variable = { # Taking "my_variable" as the variable's name, both "var:my_variable" and "my_variable" are valid options, left up to the developer's preference.
        army_experience = 100
    }
}

If the country flag inward_perfect_flag is set, it'll multiply the above chance of 30 by 1.3 to get 39. Meanwhile, my_variable will take the value of the according temp variable or the current scope's variable as the weight of the option.

Note that if you want to create a repeatable decision including a random list, by default the same decision will pick the same random result every time it is triggered in a game. You can reverse this behaviour by including the following line in the decision block:

fixed_random_seed = no

This is only for decisions. Elsewhere, random seed is unfixed by default, making this argument unnecessary to set to "no".

Tooltip manipulation

参见：Localisation

The "tooltip" in this case refers to the text shown to the player in-game that explains what the effect block changes within the game, such as "+50 政治点数".

There are 3 ways to edit the tooltip within an effect block:

• hidden_effect = { ... } is used in order to hide the effects within from the tooltip, making their execution not get shown to the player.
• effect_tooltip = { ... } is, instead, used in order to put the effects into the tooltip without actually executing them.
• custom_effect_tooltip = my_localisation_key is used in order to put an arbitrary paragraph of text as an effect that will get executed.

For example, this sample focus' completion reward utilises all three:

completion_reward = { 
    hidden_effect = {
        every_subject_country = { country_event = my_event.1 }
    }
    custom_effect_tooltip = send_event_to_subjects_tt
    effect_tooltip = {
        add_political_power = 100
    }
    custom_effect_tooltip = reject_war_tt
}

In this case, send_event_to_subjects_tt and reject_war_tt are localisation keys defined within any /Hearts of Iron IV/localisation/english/*_l_english.yml file encoded with UTF-8-BOM, assuming the English language.

 send_event_to_subjects_tt: "Sends a demand to our every subject.\nIf they agree, we get the following for each subject:"
 reject_war_tt: "If they reject the demand, we gain a wargoal against them."

In-game, this will appear as such:

Effect: Sends a demand to our every subject. If they agree, we get the following for each subject: Political Power: +100 If they reject the demand, we gain a wargoal against them.

Noticably, the effect that fires the country event gets hidden from the tooltip. After completing the focus, the only thing that happens is that every subject country receives an event with the ID of my_event.1, the country does not immediately gain 100 political power.

Meta effects

Meta effects allow you to use non-dynamic effects (the ones that do not accept modifiers and can only use static tokens or constant values) as if they were accepting variables.

add_equipment_to_stockpile = {
    type = infantry_equipment_2
    amount = eq_amount
}

In the effect shown above, amount of equipment added is dynamic and can be set using the variable "eq_amount". However, this effect does not let you use a variable as equipment type. You can not store "infantry_equipment_2" in a variable and use it here.

However, meta effects will let you use variables and scripted localization within them to build effects as if they were texts and run them. Let's make previous effect accept equipment type and equipment level as variables stored in "eq_type" and "eq_level".

set_variable = { eq_type = 1 } # Sets the equipment type to "1", which determines the equipment given using scripted localisation, included below
set_variable = { eq_amount = 10 } # Sets the amount of equipment given to 10
set_variable = { eq_level = 2 } # Sets the equipment level to 2, which is used directly in the meta effect, no scripted localisation required

meta_effect = { # The actual meta effect. This can go anywhere you need it: in a decision, in a scripted effect, in a scripted GUI click effect, etc...
    text = {
        add_equipment_to_stockpile = {
            type = [EQ_TYPE]_[EQ_LEVEL]
            amount = eq_amount
        }
    }
    EQ_LEVEL = "[?eq_level|.0]" # Gets the "eq_level" variable and saves it as "EQ_LEVEL" for the meta effect to use
    EQ_TYPE = "[This.GetEquipmentName]" # Gets the equipment type from scripted localisation, included below, based on the "eq_type" variable, and saves it as "EQ_TYPE" for the meta effect to use
}

# The scripted localization for the "eq_type" variable, which goes in a scripted localisation file
defined_text = { # Since the "eq_type" variable in this example is equal to 1, the equipment given by the effect is "artillery_equipment"
    name = GetEquipmentName
    text = {
        trigger = {
            check_variable = { eq_type = 0 }
        }
        localization_key = "infantry_equipment"
    }
    text = {
        trigger = {
            check_variable = { eq_type = 1 }
        }
        localization_key = "artillery_equipment"
    }
}

As you can see, we have created a meta_effect that takes two arguments. These arguments will be used replacing the parameters [EQ_TYPE] and [EQ_LEVEL] inside the meta effect. EQ_LEVEL will be replaced by [?eq_level|.0] which is the integer value of eq_level (in this case 2.000 becomes 2). EQ_TYPE is a bit more complicated, it is being replaced by a scripted localization. This scripted localization will check eq_type variable and depending on its value it will return the key token for the equipment. If it is 0, it will return "infantry_equipment". If it is 1, it will return "artillery_equipment".

So the final result is [EQ_TYPE] is being replaced by "artillery_equipment" and [EQ_LEVEL] is being replaced by "2" and in the end our effect will be built as:

add_equipment_to_stockpile = {
    type = artillery_equipment_2
    amount = eq_amount
}

which will give you 10 artillery_equipment_2.

debug = yes can be added to meta effects. Which will print the final effect to game.log when the effect is executed and make debugging easier.

Scripted effects

Scripted effects serve a similar purpose to functions in that they can be defined in /Hearts of Iron IV/common/scripted_effects/*.txt and then used elsewhere as a shortened version. A scripted effect will never run by itself and requires being used as an effect elsewhere to be executed. Alongside that, the game allows the creation of custom console commands, which are scripted effects.

A scripted effect is defined simply as

scripted_effect_name = {
	<effects>
}

This example can be used as an effect in regular code as scripted_effect_name = yes.

Scripted effects can be accessed in console by typing e scripted_effect_name to run them.

To create a custom console command, the scripted effect's name should begin with d_. The console command itself does not include d_, so d_test_command would be run in console as test_command
In custom console commands, the country running the command is FROM, while ROOT is the selected country, state, or character. Anything entered after the console command, separated by spaces like test_command 123 321 GER is added to the 'args' temp array. An example of a scripted effect which will transfer every state entered as an argument to the country that runs the console command is

d_transfer_states = {
	for_each_scope_loop = {
		array = args
		FROM = {
			transfer_state = PREV
		}
	}
}

used like transfer_states 123 321

Useful scripted effects

These scripted effects are defined in base game and might be useful to keep in the mod to cut down on the amount of code. As scripted effects, all of these use a boolean value as argument.

Base game scripted effects:

Name	Scope	Example	Description	Notes
instantiate_collaboration_government	Country	instantiate_collaboration_government = yes	Creates a collaboration government, with the current scope as overlord.	The target of the collaboration government is stored in the country_to_initiate temp variable.
upgrade_economy_law	Country	upgrade_economy_law = yes	Switches the economy law one level towards total mobilisation.	If already on total mobilisation, adds 150 政治点数. Must be adjusted manually for new laws.
gain_random_agency_upgrade	Country	gain_random_agency_upgrade = yes	Grants a random available intelligence agency upgrade.	Only results in an agency being created if one doesn't exist.
add_ruling_to_dem	Country	add_ruling_to_dem = yes	All of the ruling party's popularity gets added to the 民主主义 ideology group.	Requires manual adjustment if new ideologies are added. See also: add_ruling_to_fas, add_ruling_to_com, add_ruling_to_neu
