is_researching_technology 常用于在某项研究进行中时动态解锁决策、触发事件或给予奖励，例如当国家正在研究某一坦克科技时弹出情报事件或加速进度。也可用于 AI 策略的 limit 块，避免 AI 重复触发与研究相关的行为。
# 当国家正在研究机械化步兵时，才允许激活某个特定决策
available = {
is_researching_technology = mechanised_infantry
}
[can_research](/wiki/trigger/can_research)：先用 can_research 确认该科技是否合法可研，再用 is_researching_technology 确认是否已经在队列中，两者配合避免逻辑空洞。[add_tech_bonus](/wiki/effect/add_tech_bonus)：在研究进行中奖励科研加成，配合 is_researching_technology 作为触发条件，实现"研究中追加 buff"的设计。[has_completed_focus](/wiki/trigger/has_completed_focus)：常见组合是先判断某国策已完成，再判断是否正在研究对应科技，构建层级解锁条件。[amount_research_slots](/wiki/trigger/amount_research_slots)：与研究槽数量条件并列使用，确保国家在资源充足时才触发相关奖励或事件。is_researching_technology 只检查正在研究中（即占用研究槽），不代表该科技已经解锁完毕；若要判断科技是否已研完，应使用 has_tech（注意：has_tech 不在本 scope 白名单内，但属于游戏内置 trigger，请勿与本 trigger 混淆）。technologies 文件夹中定义的 token 完全一致（区分大小写），填写显示名称或本地化字符串会导致条件永远返回假且不报错，极难排查。Hands-on notes are AI-generated and checked against the vanilla command vocabulary — treat them as a starting point, not authoritative reference.

is_researching_technology is commonly used to dynamically unlock decisions, trigger events, or grant rewards while a particular technology is being researched. For example, you can pop an intelligence event or accelerate research progress when a nation is researching a specific tank technology. It can also be used in the limit block of AI strategies to prevent the AI from repeatedly triggering research-related behaviors.
# Only allow activating a specific decision when the country is researching mechanised infantry
available = {
is_researching_technology = mechanised_infantry
}
[can_research](/wiki/trigger/can_research): First use can_research to confirm whether the technology is legally researchable, then use is_researching_technology to confirm whether it's already in the queue. Using both together avoids logical gaps.[add_tech_bonus](/wiki/effect/add_tech_bonus): Award research bonuses while research is in progress, using is_researching_technology as the trigger condition to implement the "add buff during research" design pattern.[has_completed_focus](/wiki/trigger/has_completed_focus): A common combination is to first check if a certain national focus is completed, then check whether the corresponding technology is being researched, creating hierarchical unlock conditions.[amount_research_slots](/wiki/trigger/amount_research_slots): Use alongside research slot quantity conditions to ensure the nation triggers relevant rewards or events only when resources are sufficient.is_researching_technology only checks if a technology is currently being researched (i.e., occupying a research slot), not whether it has been fully unlocked. To determine if a technology has been completed, use has_tech instead (note: has_tech is not on this scope's whitelist, but it is a built-in game trigger—do not confuse it with this trigger).technologies folder (case-sensitive). Using display names or localization strings will cause the condition to always return false without error, making it extremely difficult to debug.
