实战用法

has_idea 常用于检测某国是否持有特定国策思潮、顾问或精神 buff，从而决定后续事件或决议是否可用。例如在自定义国策树中，限定只有已获得某经济法规的国家才能触发下一阶段选项，或在事件中根据是否携带特定军事顾问 idea 来分支对话。

# 仅当该国持有"战时经济"思潮时，决议才可用
available = {
    has_idea = war_economy
}

配合关系

[has_completed_focus](/wiki/trigger/has_completed_focus)：先判断完成了某个国策，再用 has_idea 确认该国策附加的 idea 是否真正生效，两者双重验证，避免因 idea 被其他途径移除而导致逻辑漏洞。
[add_ideas](/wiki/effect/add_ideas)：在 effect 块中为国家添加 idea，通常在 trigger 块中先用 has_idea 判断该 idea 不存在才执行，防止重复叠加。
[remove_ideas](/wiki/effect/remove_ideas)（白名单内以 add_ideas 对应的移除操作）搭配使用：先用 has_idea 确认 idea 存在，再安全地将其移除，避免对不存在的 idea 执行移除时产生报错或静默失败。
[has_dynamic_modifier](/wiki/trigger/has_dynamic_modifier)：has_idea 检查静态 idea，has_dynamic_modifier 检查动态修正器，两者配合可完整覆盖国家所有增益/减益状态的判断逻辑。

常见坑

idea 名称大小写或拼写错误：has_idea 的参数必须与 ideas = { ... } 定义块中的 idea token 完全一致，哪怕一个下划线之差也会静默返回 false 而不报错，非常难以排查。
混淆 idea 与 advisor character：在新版本中顾问系统已迁移到 character 体系，部分顾问不再作为传统 idea 注册；对这类顾问使用 has_idea 会永远返回 false，应改用 [has_character](/wiki/trigger/has_character) 或 [has_country_leader](/wiki/trigger/has_country_leader) 进行检测。

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

has_idea is commonly used to check whether a nation possesses a specific national focus ideology, advisor, or spirit buff, thereby determining whether subsequent events or decisions are available. For example, in a custom focus tree, you can restrict the next phase of options to only nations that have acquired a certain economic law idea, or in an event, branch dialogue based on whether a specific military advisor idea is present.

# Decision is only available if the nation has the "war_economy" idea
available = {
    has_idea = war_economy
}

Synergy

[has_completed_focus](/wiki/trigger/has_completed_focus): First check whether a specific focus has been completed, then use has_idea to confirm that the idea granted by that focus is actually in effect. This double verification prevents logical gaps caused by ideas being removed through other means.
[add_ideas](/wiki/effect/add_ideas): Add ideas to a nation within an effect block. Typically, first check in a trigger block using has_idea to ensure the idea does not already exist before execution, preventing duplicate stacking.
[remove_ideas](/wiki/effect/remove_ideas) (paired removal operations corresponding to add_ideas entries): First confirm the idea's existence using has_idea, then safely remove it to avoid errors or silent failures when attempting to remove non-existent ideas.
[has_dynamic_modifier](/wiki/trigger/has_dynamic_modifier): has_idea checks static ideas while has_dynamic_modifier checks dynamic modifiers. Used together, they provide complete coverage for evaluating all bonus/penalty states of a nation.

Common Pitfalls

Incorrect capitalization or spelling of idea names: The parameter for has_idea must match the idea token in the ideas = { ... } definition block exactly. Even a single underscore difference will silently return false without error, making it extremely difficult to debug.
Confusing ideas with advisor characters: In newer versions, the advisor system has migrated to the character framework, and some advisors are no longer registered as traditional ideas. Using has_idea on such advisors will always return false. Use [has_character](/wiki/trigger/has_character) or [has_country_leader](/wiki/trigger/has_country_leader) instead.
