Flow control[edit | edit source]

Ambox outdated info.png
Please help with verifying or updating this section. It was last verified for version 1.24.

These are effect scopes that alter the flow of execution in some way.

Hidden effect[edit | edit source]

It is possible to hide the automatic tooltip that effect generate, especially if you want the result of the effect to be hidden to the player.

You can do this by using the hidden_effect scope around the effects you wish to hide. The format is as follows: 

hidden_effect = {
    <effects>
}

Tooltip[edit | edit source]

It is possible to display the automatic tooltip that effects generate without actually executing the effects.

You can do this by using the tooltip scope around the effects. The format is as follows: 

tooltip = {
    <effects>
}

If, Else if and Else[edit | edit source]

The if, else_if and else scopes are used to introduce effects within an effect scope that hidge on a set of trigger values.

The if scope was introduced in Patch 1.1. The format is as follows: 

if = {
    limit = {
        <triggers>
    }
    
    <effects>
}

In Patch 1.23, support for else_if and else was added. The format is as follows: 

if = {
    limit = {
        <triggers>
    }
    <effects>
}   
 
# optional - executed when the trigger values return false, and the else_if trigger values return true
else_if = {
    limit = {
        <triggers
    }
    <effects>
}
    
# optional - executed when the trigger values return false
else = {
    <effects>
}

Note that you can nest if scopes, allowing for multiple layers of triggers and effects.

While[edit | edit source]

The while scope is used to repeat execution of a set of effects whilst a set of trigger values remain true.

Introduced in Patch 1.18, the format is as follows: 

while = {
    limit = {
        <triggers>
    }
    
    <effects>
}

Note:

  • A while scope loop will continue for 100,000 loops if the trigger values never become false. After which, it will terminate.
  • A while scope will produce no tooltip.

Due to the nature of execution flow in game, you ideally need to add effects within the while scope effect section that make the trigger values false. There is no way to reduce the execution rate, so the effects will be triggered multiple times a second otherwise.

Trigger switch[edit | edit source]

The trigger_switch scope is used in conjunction with triggers that return single, discrete values. You list each trigger value you wish to act on, and add the effects within. The first valid trigger from the top will occur, the rest are skipped.

The format is as follows: 

trigger_switch = {
    on_trigger = <trigger>
    <trigger value> = { <effect> }
    <trigger value> = { <effect> }
}

As an example, let's say you want to add 1 stability for western countries, and remove 1 stability for eastern countries. You can do this with an if scope, but it will be more verbose compared to a trigger_switch: 

trigger_switch = {
    on_trigger = technology_group
    western = { add_stability = 1 }
    eastern = { add_stability = -1 }
}

Random and random lists[edit | edit source]

It is possible to randomly execute effects with both the random and random_list scopes.

The random scope is used to add a single random roll to a set of effects. The format is as follows: 

random = { 
    chance = 50 

    <effects>
}

The chance is out of 100, and only displays integer values in game, although it does accept decimal values.

The random_list scope is used to add different sets of effects to a single random roll. The format is as follows: 

random_list = {
    <chance> = {
        <effects>
    }
    <chance> = {
        <effects>
    }
}

Note that the chance total will be out of 100. If the chance values used do not add up to 100, they will be scaled to maintain the same ratio.

The random_list accepts parameters as chance values when in a file in a scripted_effect. For example: 

random_list = {
    $chance_of_secondary$ = { set_country_flag = jewish_advisor }
    $chance_of_primary$ = { set_country_flag = state_religion_advisor }
    $chance_of_secondary$ = { set_country_flag = protestant_or_coptic_advisor }
    $chance_of_secondary$ = { set_country_flag = reformed_or_orthodox_advisor }
    $chance_of_tertiary$ = { set_country_flag = heathen_advisor }
}

Note: It is important to understand that both of these scopes may not always return a random result. This occurs when they are used in a non-seeded script location. An example of this are decisions and any events in the same event chain, using a random scope there will always return the same result everytime the decision is done. To get around this, use a temporary province triggered modifier anywhere to trigger a (separate) event in its on_activation on the next day, or use an on action like on_adm_development for same-day results.

Scripted effects[edit | edit source]

Scripted effects are essentially macros that can be used in events, decisions, etc. to improve readability. By keeping the messy code within a scripted effect, it can be easier to maintain readability.

Scripted effects are found in /Europa Universalis IV/common/scripted_effects/*.txt.

Here is a scripted effect that reduces 7 lines down to one: 

clear_religious_scholar_modifiers_effect = {
	remove_country_modifier = hanafi_scholar_modifier
	remove_country_modifier = hanbali_scholar_modifier
	remove_country_modifier = maliki_scholar_modifier
	remove_country_modifier = shafii_scholar_modifier
	remove_country_modifier = ismaili_scholar_modifier
	remove_country_modifier = jafari_scholar_modifier
	remove_country_modifier = zaidi_scholar_modifier
}

In the event the following is added to execute the scripted effect: 

clear_religious_scholar_modifiers_effect = yes

Scripted effects now accepted parameters in Patch 1.23. This means you can pass along data into the scripted effect, allowing for much more generalized usage.

To define a parameter within a scripted effect, simply surround the key with $ marks. i.e. $DURATION$.

Here is a scripted effect that adds or extends any province modifier passed to it: 

add_or_extend_province_modifier_effect = {
	if = {
		limit = {
			has_province_modifier = $MODIFIER$
		}
		extend_province_modifier = { name = $MODIFIER$ duration = $DURATION$ }
	}
	else = {
		add_province_modifier = { name = $MODIFIER$ duration = $DURATION$ }
	}
}

In the event the following is added to execute the scripted effect: 

add_or_extend_province_modifier_effect = { MODIFIER = pasha_removed_modifier DURATION = 3650 }

Scripted Effects/Triggers can also accept a special type of argument trigger, which enables a certain block of code when called from in the original event location. This allows for specific actions to be run by the script without the usage of extensive if/else statements.

To define such an argument within a scripted effect, surround the block of code with square brackets [. i.e. [[fort]]

Here is an example of such an argument:

add_latest_building = {
	[[fort]
		if = {
			limit = { $builder$ = { mil_tech = 24 } }
			add_building = fort_18th
		}
		else_if = {
			limit = { $builder$ = { mil_tech = 19 } }
			add_building = fort_17th
		}
		else_if = {
			limit = { $builder$ = { mil_tech = 14 } }
			add_building = fort_16th
		}
		else = {
			add_building = fort_15th
		}
	]
	[[tax]
		if = {
			limit = { $builder$ = { adm_tech = 19 } }
			add_building = cathedral
		}
		else = {
			add_building = temple
		}
	]
}

In the event file the following can be used to call the scripted effect:

add_latest_building = { builder = ROOT fort = yes }
