实战用法

此 trigger 常用于防御战争相关的事件或决策场景，例如为正在被侵略的国家解锁特殊援助选项、激活抵抗加成 idea，或触发"本土保卫战"类型的剧本事件。下面示例展示一个决策：仅当本国处于针对特定敌国的防御战争时才可用。

available = {
    has_defensive_war_with = FROM
}

也可在事件触发条件中使用，判断玩家国家是否正被某目标国侵略：

trigger = {
    has_defensive_war_with = ROOT
}

配合关系

[has_defensive_war](/wiki/trigger/has_defensive_war)：has_defensive_war 只判断"是否存在任何防御战争"，而 has_defensive_war_with 精确到对手国家，两者常嵌套或并列使用，先粗筛再精确锁定目标。
[any_enemy_country](/wiki/trigger/any_enemy_country)：可在 any_enemy_country 的子条件中配合使用，遍历敌国并用 has_defensive_war_with 筛选出真正的攻击方，逻辑更严谨。
[has_war_goal_against](/wiki/trigger/has_war_goal_against) (见下注)／[can_declare_war_on](/wiki/trigger/can_declare_war_on)：配合后者可在 AI 策略或决策中区分"防御中"与"可宣战"两种互斥状态，避免逻辑冲突。
[add_ideas](/wiki/effect/add_ideas)：当条件满足时添加"全国动员"类 idea，赋予防御方战时加成，是最典型的 effect 配合方式。

常见坑

scope 方向混淆：trigger 的执行 scope 必须是其中一方（Country A），而填入的 target 是另一方（Country B），含义是"A 对 B 拥有防御战争"。新手容易把双方搞反，导致条件始终不触发——务必确认"谁在 scope 里、谁是参数"。
target 写错标签格式：target 只接受 THIS/ROOT/PREV/FROM/OWNER 等动态 scope 关键词，不能直接写国家 tag 字符串（如 GER），否则脚本解析会静默失败，条件永远为假。

Hands-On Notes

Hands-on notes are AI-generated and checked against the vanilla command vocabulary — treat them as a starting point, not authoritative reference. The definition above is the game's own documentation.

Hands-On Usage

This trigger is commonly used in defensive war-related events or decision scenarios, such as unlocking special aid options for invaded nations, activating resistance bonus ideas, or triggering "homeland defense" type scripted events. The example below shows a decision that is only available when your country is in a defensive war against a specific enemy.

available = {
    has_defensive_war_with = FROM
}

It can also be used in event trigger conditions to check whether the player's nation is being invaded by a target nation:

trigger = {
    has_defensive_war_with = ROOT
}

Synergy

[has_defensive_war](/wiki/trigger/has_defensive_war): has_defensive_war only checks "whether any defensive war exists", while has_defensive_war_with pinpoints the opposing nation. Both are often nested or used in parallel—first coarse filtering, then precise target identification.
[any_enemy_country](/wiki/trigger/any_enemy_country): Can be used within any_enemy_country subscopes to iterate through enemy nations and filter actual attackers with has_defensive_war_with, providing more rigorous logic.
[has_war_goal_against](/wiki/trigger/has_war_goal_against) (see note below) / [can_declare_war_on](/wiki/trigger/can_declare_war_on): When combined, these allow distinguishing between "currently defending" and "can declare war" as mutually exclusive states in AI strategies or decisions, avoiding logical conflicts.
[add_ideas](/wiki/effect/add_ideas): When conditions are met, adds "full mobilization" type ideas to grant the defending nation wartime bonuses—the most typical effect synergy.

Common Pitfalls

Scope direction confusion: The trigger's execution scope must be one party (Country A), while the filled target is the other party (Country B). The meaning is "A has a defensive war against B". Beginners often reverse the two sides, causing the condition to never trigger—always confirm "who is in scope and who is the parameter".
Target tag format error: The target only accepts dynamic scope keywords like THIS/ROOT/PREV/FROM/OWNER, and cannot directly write nation tag strings (e.g., GER). Otherwise the script parsing will silently fail and the condition will always be false.
