Conditions (also known as Triggers) are used to check whether certain conditions are fulfilled in the game's current state or not, without being able to change anything in the game's state.[a] These return a boolean (true or false), which may be interpreted by the block where it's used. Usually blocks that allow using triggers are an AND unless stated otherwise, which would instantly stop execution upon receiving a single false statement and return false.

The list of triggers may be outdated. A complete, but unsorted, list of triggers can be found in /Hearts of Iron IV/documentation/triggers_documentation.html or /Hearts of Iron IV/documentation/triggers_documentation.md. As of 1.12.14, this file was last updated in the version 1.11.4.


Operators

File:Ambox outdated info.png
這部分內容可能已不適合當前版本，最後更新於1.13。

Every trigger uses one of the three operators: The equality sign = or the comparison signs > and <.

The equality sign can either mean strict equality (Unlike previous games in the series where it checked for being equal or greater than) or can serve as a way to introduce a block of additional triggers, as in has_opinion = { target = GRE value < -10 }. The comparison signs serves as strict comparison: has_political_power > 100 will not be true if the country has exactly 100 political power, for instance.

Not all triggers support the equality sign or comparison signs. See the details for each trigger in the notes for it. If not stated otherwise, the trigger only supports the equality sign.

Context scopes

File:Ambox outdated info.png
這部分內容可能已不適合當前版本，最後更新於1.13。

There are three general scopes all triggers operate in:

  • country
  • state
  • character

They give context to a trigger by stating what the trigger is checking against.

Each country acts as a sub-scope of the general country scope, i.e. GER = { } will check only against Germany, whereas any_country will check against all countries. Likewise for states and characters.

Triggers won't work in scopes they are not assigned to. Country triggers will not work for states or vice-versa.

Scopes

主條目：Scopes

These don't serve as triggers, but rather as scopes that change for whom the triggers are being checked. Each one also serves as an AND statement.

Trigger scopes

These can only be used as triggers; trying to use them as effects will result in nothing happening.

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.

Flow control tools

These are triggers that serve as more of a way to establish a connection in how triggers are evaluated. Each one serves as a trigger scope with additional arguments and can be used regardless of scope.

Flow control tools:
Name Additional parameters Examples Description Notes Version Added
AND None 
AND = {
    original_tag = GER
    has_stability > 0.5
}
 Returns false if any sub-trigger returns false, true otherwise. Evaluation stops at the first false sub-trigger. Only necessary within OR statements and NOT statements, as everything else is implicitly AND. 1.0
OR None 
OR = {
    original_tag = ENG
    original_tag = USA
}
 Returns true if any sub-trigger returns true, false otherwise. Evaluation stops at the first true sub-trigger. 1.0
NOT None 
NOT = {
    has_stability > 0.5
    has_war_support > 0.5
}
 Returns false if any sub-trigger returns true, true otherwise. Evaluation stops at the first true sub-trigger. Equivalent to a NOR rather than a NAND. 1.0
count_triggers amount = <int>
The amount of triggers that need to be fulfilled. 
count_triggers = {
    amount = 2
    10 = { state_population = 100000 }
    11 = { state_population = 100000 }
    12 = { state_population = 100000 }
}
 Sums the results of all sub-triggers (false=0, true=1) and returns true if the sum is at least amount. 1.5
if limit = <trigger block>

else_if = <if-trigger>
Alternative condition. Optional.
else = <AND-trigger>
Final alternative condition. Optional. 

if = {
    limit = {
        has_dlc = "Poland: United and Ready"
    }
    has_political_power > 100
}
else_if = {
    limit = {
        has_dlc = "Waking the Tiger"
    }
    has_war_support > 0.5
}
else = {
    always = no
}
If limit is true, the sub-triggers are evaluated like an AND-trigger. If limit is false, else_if blocks are tried in sequence and finally else (if present). Otherwise true is returned. Both nested (As in inside of if = { ... }) and unnested (As in the example) else and else_if exist. In case of overlap, unnested is preferred.

Can be useful for tooltip management: same as in effects, if the limit is unmet, nothing appears. If it is met, then the limit is hidden while the condition outside of the limit appears in the tooltip.

if = { limit = { trigger_1 = yes } trigger_2 = yes } is equivalent to OR = { NOT = { trigger_1 = yes } trigger_2 = yes }, but generates a different tooltip.

1.0
hidden_trigger None 
hidden_trigger = {
    country_exists = GER
}
 Hides the triggers from the tooltip shown to the player. Also serves as an AND statement. 1.0
custom_trigger_tooltip tooltip = <string>
The localisation key to use. 
custom_trigger_tooltip = {
    tooltip = sunrise_invasion_tt		
    any_state = {
        is_owned_by = JAP
        is_on_continent = europe
        is_coastal = yes
    }
}
 Hides the triggers from the tooltip shown to the player and instead uses the specified localisation key. Also serves as an AND statement. When required to be false (as with NOT), the game will use the same localisation key but with _NOT appended (as in sunrise_invasion_tt_NOT in the example). If it doesn't exist, the same tooltip as for being true will get re-used, possibly causing player confusion. 1.0

Variables

File:Ambox outdated info.png
這部分內容可能已不適合當前版本，最後更新於1.13。
Variable-related triggers:
Name Parameters Examples Description Notes Version Added
has_variable <variable>
The variable to check. 
has_variable = my_var
 Checks if the specified variable exists for the current scope. 1.5
check_variable var = <variable>
The variable to check.

value = <float> / <variable>
The value to check for.
compare = <type>
The type of comparison. Optional, can use < or > instead. 

check_variable = {
    var = my_var
    value = 10
    compare = greater_than_or_equals
}

check_variable = {
    my_var > 10
}
Check the specified variable for the current scope. Possible compare types:
  • less_than
  • less_than_or_equals
  • greater_than
  • greater_than_or_equals
  • equals
  • not_equals
 1.5

Remember that variables need to refer to the scope they were set in. This means you can't check a country variable in a state scope without scoping the variable.

For example, to get the country variable whilst in a state scope, you'd do the following: 

<country> = {
    <state> = {
        limit = {
            check_variable = { from.my_country_var > 0.0 }
        }
    }
}

See Variables for more information.

Meta triggers

File:Ambox outdated info.png
這部分內容可能已不適合當前版本，最後更新於1.13。

Meta triggers are a system added with 1.6 with 炮手就位炮手就位[4] used in the exact same manner as meta effects: in order to tie a trigger block to a dynamic localisation entry. This is usually used in conjunction with scripted localisation for non-numerical checks. This also can serve in order to place a variable check where one is not possible.
Meta triggers work in any scope that supports triggers, including combat scope.

The following arguments go inside of a scripted trigger:

  • text = { ... } is a trigger block used by the meta trigger. In here, any string that must be made dynamic is marked with the square brackets on each side as [EXAMPLE].
  • EXAMPLE = "..." is a string that will serve as the dynamic replacement for [EXAMPLE] within text = { ... }. This accepts dynamic localisation to a limited degree, such as getting a variable's value with [?var_name] or some namespaces like [ROOT.GetTag].
  • debug = yes, if added, will add the final output in the user directory's /Hearts of Iron IV/logs/game.log file for debugging purposes.

For example, the following can be used with has_equipment to make it depend on a variable's value: 

meta_trigger = {
    text = {
        has_equipment = { [EQUIPMENT_ARCHETYPE] > 100 }
    }
    EQUIPMENT_ARCHETYPE = "[GetEquipmentArchetype]"
}

In this case, GetEquipmentArchetype is scripted localisation. An example definition of scripted localisation in this case is as such: 

defined_text = {
    name = GetEquipmentArchetype
    text = {
        trigger = {
            check_variable = { v = 0 }
        }
        localization_key = artillery_equipment
    }
    text = {
        localization_key = infantry_equipment
    }
}

Scripted triggers

File:Ambox outdated info.png
這部分內容可能已不適合當前版本，最後更新於1.13。

Scripted triggers serve a similar purpose to functions in that they can be defined in /Hearts of Iron IV/common/scripted_triggers/*.txt and then used elsewhere as a shortened version. Alongside that, the game has certain base game scripted triggers that are checked directly in the game's code determining triggers for functions that cannot be changed.

A scripted trigger is defined simply as 

scripted_trigger_name = {
	<triggers>
}

This example can be used as a trigger in regular code as scripted_trigger_name = yes or scripted_trigger_name = no.

For example, this would be the definition in any scripted trigger file: 

state_is_in_area = {
    OR = {
        state = 120
        state = 121
        state = 123
        state = 124
        state = 125
    }
}

This can then be used in any other trigger block, such as a national focus' available section: 

focus = {
    id = TAG_focus_id   # Optional attributes, other than available, have been omitted
    available = {
        capital_scope = {
            state_is_in_area = yes
        }
    }
}

If there are several definitions of scripted triggers with the exact same name, the game will make the scripted trigger be the one that was evaluated later, as decided by file names and order in files.

Diplomacy scripted triggers

File:Ambox outdated info.png
這部分內容可能已不適合當前版本，最後更新於1.13。

Diplomacy scripted triggers fall into two mutually exclusive groups: deciding availability and deciding visibility. By default, these are defined in /Hearts of Iron IV/common/scripted_triggers/diplomacy_scripted_triggers.txt and /Hearts of Iron IV/common/scripted_triggers/00_diplo_action_valid_triggers.txt respectively. While it is possible to also use them as regular scripted triggers, they will also modify the prerequisites of being able to do a diplomatic action between 2 countries.

A diplomacy scripted trigger is identified by the naming pattern of DIPLOMACY_<action>_ENABLE_TRIGGER for availability, such as DIPLOMACY_GUARANTEE_ENABLE_TRIGGER, and is_diplomatic_action_valid_<action> for visibility, such as is_diplomatic_action_valid_stage_coup. In the base game, diplomacy scripted triggers are used to implement the game rules and add some country-specific exceptions, such as the 聯合王國的國旗 聯合王國 being unable to release its colonies with the 炮手就位炮手就位 DLC. Checking the base game's contents beforehand or copying it to the mod would ensure that the mod won't accidentally break any existing game rules.

Generally, the pattern in localisation keys used for the button usually matches up with the internal ID of a diplomatic action. If the diplomatic action doesn't already have a scripted trigger in the base game, entirety of localisation can be searched for the name of the button to find the name of the action. For example, a the English localisation entry of DIPLOMACY_CANCEL_GENERATE_WARGOAL_TITLE:0 "Cancel Justification" would suggest that the diplomatic action of cancelling justification is CANCEL_GENERATE_WARGOAL.

Know tokens for is_diplomatic_action_valid_<action> are:

  • declare_war, for the Declare War button
  • generate_wargoal, only affects the war goal menu by greying out the send button
  • guarantee, for the Guarantee Independence button
  • docking_rights, for the request docking rights button
  • offer_docking_right, for the offer docking rights button
  • create_faction, for the create faction button
  • assume_faction_leadership, for the assume leadership of faction button
  • kick_from_faction, for the kick from faction button
  • join_faction, for the ask to join faction button
  • request_access_to_licence_production, for the negotiate license button
  • embargo, for the embargo button
  • send_volunteers, only affects the sent volunteers menu by greying out the send button
  • stage_coup, for the stage coup button
  • boost_party_popularity, for the boost party popularity button

Within a diplomacy scripted trigger, the default scope is the country that does the trigger, while FROM is the target of the action. For availability, the trigger's tooltip is shown to the player when hovering over the diplomatic action; in case of country-specific restrictions, using conditional statements can ensure that the tooltip would only be generated when needed rather than between any pair of nations.

For example, this trigger will prevent BHR from revoking a guarantee on QAT, while still ensuring the game rule works otherwise: 

DIPLOMACY_REVOKE_GUARANTEE_ENABLE_TRIGGER = {
    if = {
        limit = {
            has_game_rule = {
                rule = allow_revoke_guarantees
                option = BLOCKED
            }
        }
        custom_trigger_tooltip = {
            tooltip = RULE_ALLOW_REVOKE_GUARANTEES_BLOCKED_TOOLTIP
            always = no
        }
    }
    if = {
        limit = {
            tag = BHR
            FROM = { tag = QAT }
        }
        custom_trigger_tooltip = {
            tooltip = NO_REVOKING_ON_QAT_TT
            always = no
        }
    }
}

Resistance initiation triggers

The behaviour of resistance being automatically initiated is decided by the should_initiate_resistance scripted trigger, by default defined in /Hearts of Iron IV/common/scripted_triggers/00_resistance_initiate_triggers.txt. If it is unfulfilled, the resistance will never initiate unless forced via the the force_enable_resistance effect. Likewise, the resistance will always occur if it's true unless forcefully disabled.

The scripted trigger's behaviour can be overwritten with state-specific scripted triggers, which should be named should_initiate_resistance with the list of state IDs suffixed at the end, separated by underscores. For example, this ensures that when a state 321 or 123 is controlled by the 聯合王國的國旗 聯合王國, resistance would get initiated if and only if they're national territory of 法國的國旗 法國; otherwise, the normal behaviour is used: 

should_initiate_resistance_123_321 = {
	if = {
		limit = {
			tag = ENG
		}
		is_core_of = FRA
	}
	else = {
		should_initiate_resistance = yes # If this is not done, resistance would always activate due to overwriting that scripted trigger.
	}
}

References and notes

^ a: Triggers are able to set and modify temporary variables. This temporary variable itself may be then used separately to change the game's state, such as in a MTTH block or if the trigger block is used in some effect's limit = { ... } (most commonly if statements or effect scope limits), though the usage of the variable to change the game's state is not a trigger by itself.
