Scopes

A scope is the context that conditions and commands are used in.

Overview

All script scopes operate on one of two internal scopes: country and province. Scopes that are for a country scope will not function correctly when used in a province scope.

Additionally, all script scopes operate in one of two type scopes: effect and trigger. Using an effect scope within a trigger scope will not work, and vice versa. There are scopes that operate in both type scopes.

Which base scopes are effect and which are trigger depends on the feature you are modding. For example, in a decision: potential = { } and allow = { } are trigger scopes, whereas effect = { } is an effect scope. This is normally self-evident in most cases.

Dynamic scopes

Four script scopes are unique in that they change their contents depending on where they are used. They can be used in both effect and trigger scopes.

Scope	Description	Example	Notes
ROOT	The base scope.	The ROOT scope in a country event is the country that the event fires for.
FROM	The calling scope.	The FROM scope in a country event would be the ROOT scope of another event that called it (via the country_event = {} effect).
PREV	The previous scope.	If you change the scope to FRA = { } and then to change scope to capital_scope = { } within it, the PREV scope is FRA = { }.
THIS	The current scope.	If you change scope to FRA = { } and then the THIS scope is FRA = { } whilst used within the FRA = { } scope.	This is useful for effects and triggers when you want to point to a scope that isn't the ROOT scope without more scope switching.

Logic scopes

There are three trigger scopes used to alter the boolean value of a trigger, or set of triggers. They are AND, OR and NOT.

The AND scope groups a set of triggers together, and returns true only if all triggers nested within return true as well. This scope is the default scope for all trigger scopes, so you don't need to explicitly use a AND scope most of the time.

AND = {
    tag = FRA
    stability = 1
}

The OR scope splits multiple sets of triggers, returning true if one of the sets of triggers nested within return true. This scope is used to make triggers return valid on state 1 or state 2 or state 3, and so on. Often the AND scope is used within the group multiple triggers together.

stability = 1
OR = {
    tag = FRA
    tag = CAS
}

The NOT scope inverts the truth value of a returned trigger. This allows you to check for the opposite instance of all triggers without needing an different trigger to do so. It also reverses the x or greater behaviour with numbers in triggers, making it less than x.

NOT = { stability = 1 }    # Returns true when stability is less than 1

There is no "implication" scope. If you need to express one (e.g. P → Q, "if P then Q"), use the logical equivalent with OR and negation instead (¬P ∨ Q, "(not P) or Q"). For example, the game encodes one of the conditions for using various religious CBs - "If Art of War is active and attacker and defender are both members of the Holy Roman Empire: the Peace of Westphalia has not occurred" - as something like the following:

OR = {
    NOT = { has_dlc = "Art of War" }
    is_part_of_hre = no
    FROM = { is_part_of_hre = no }
    hre_religion_treaty = no
}

Subscopes

Many scopes return multiple subscopes. For example, every_owned_province = { } returns every owned province scope. This means any effect within this scope is executed in every province subscope. Likewise for trigger scopes, just with comparison instead.

A quick reference on which scopes operate in this way:

Scope Prefix	Type	Description
all_<scope>	Trigger	Requires valid trigger matches for all subscopes.
any_<scope>	Trigger	Requires valid trigger matches for one subscope in the set.
every_<scope>	Effect	Applies effects to all subscopes.
random_<scope>	Effect	Applies effects to one random subscope.

Limit scope

For all effect scopes, you can nest a limit = { } to filter the returned subscopes.

For example, the following returns subscopes of countries that have 3 Stability:

every_country = {
    limit = {
        stability = 3
    }
}

Trigger scopes are inherently used for filtering, so do not require a limit scope.

Tradenode scopes

Theoretically tradenode scopes are province scopes. However, in practice you need to be within a tradenode scope to use tradenode effect and trigger scopes.

This means you cannot do this:

ROOT = {
    every_privateering_country = {
    
    }
}

Rather, you need to do this:

ROOT = {
    random_active_trade_node = {
        every_privateering_country = {
            
        }
    }
}

Dual scopes

Dual scopes can be used in both effect and trigger contexts. However they operate differently in either context.

In an effect scope, a dual scope will act like every_<scope> and apply effects to all subscopes.

In an trigger scope, a dual scope will act like any_<scope> and match for one subscope in the set.

You can alter this for dual scopes that return more than one subscope by including the type = all line within the dual scope. This will make the dual scope match for all subscopes.

<region> = {
    
    type = all
}

Effect scopes

All effect scopes that potentially match multiple subscopes, plus if, can be limited with the limit = { } scope within. For example:

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

Scopes that choose one random subscope (e.g. random_owned_province) make their choice after applying the limit.
