effect · set_war_support

Hands-On Usage

set_war_support is commonly used in national focuses, events, or decisions to force war support to a fixed value, making it ideal for narrative moments requiring precise control over morale (such as resetting a nation's morale to zero or maxing it out after a historical event trigger). Unlike add_war_support, which applies relative adjustments, this command directly overwrites the current value, suited for "reset" scenarios rather than "fine-tuning" needs.

# An event causes the nation to fall into war weariness; directly force war support down
country_event = {
    id = my_mod.5
    option = {
        name = my_mod.5.a
        set_war_support = 10   # Force to 10%, not an addition to the current value
    }
}

Synergy

• [add_war_support](/wiki/effect/add_war_support): The two are complementary—set_war_support anchors the initial value firmly, then add_war_support applies dynamic fine-tuning afterward, avoiding cumulative errors.
• [add_stability](/wiki/effect/add_stability): War support and stability are typically adjusted in tandem within the same event, jointly reflecting shifts in the domestic political climate.
• [has_war_support](/wiki/trigger/has_war_support) (note: use the corresponding war support trigger from the whitelist)—should actually be paired with [has_bombing_war_support](/wiki/trigger/has_bombing_war_support) or [has_casualties_war_support](/wiki/trigger/has_casualties_war_support) as precondition checks to confirm the current morale threshold before deciding whether forced overwrite execution is necessary.
• [add_ideas](/wiki/effect/add_ideas): Often used together in the same option to narratively explain why war support fluctuates sharply, maintaining logical consistency in the game's presentation.

Common Pitfalls

1. Logic errors from mixing with add_war_support: Beginners often use set_war_support = 50 when war support is already high, expecting it to "add up to 50"—but this command directly overwrites the value. If the current value is already above the target, support will actually decrease. Always check with [has_war_support](/wiki/trigger/has_war_support)-type triggers first to decide which command to use.
2. Unvalidated numeric ranges: Passing values outside the game's allowed range (typically 0–100) may cause the engine to truncate silently or produce unexpected behavior. It's recommended to enforce valid ranges in your script logic itself rather than relying on engine-side boundary protection.
