实战用法

set_research_slots 常用于国策完成、事件触发或特定条件达成后，直接将某国的研究槽数量设定为目标值，例如为一个弱小国家提供开局增益，或在剧本中模拟技术爆发期。与仅增加单个槽的命令不同，它适合需要"精确控制总量"的场合（如将研究槽固定为某个数值，而不管当前是多少）。

# 国策完成后将研究槽设为 5
focus = {
    id = SCI_research_boom
    ...
    completion_reward = {
        set_research_slots = 5
    }
}

配合关系

[add_research_slot](/wiki/effect/add_research_slot) — 两者互补：set_research_slots 用于精确设置总量，add_research_slot 用于在现有基础上增减，结合使用可实现"先重置再叠加"的复杂逻辑。
[amount_research_slots](/wiki/trigger/amount_research_slots) — 触发条件配合：在执行 set_research_slots 前，先用此 trigger 检查当前研究槽数量，避免意外降低已有槽位（如玩家通过其他途径已获得更多槽）。
[add_ideas](/wiki/effect/add_ideas) — 研究槽改动常与国家精神绑定，用 add_ideas 同步添加提供研究加成的 idea，形成完整的科研强化包。
[add_tech_bonus](/wiki/effect/add_tech_bonus) — 同场景下常见搭档，在设置槽位的同时给予特定科技的研究加速，模拟国家科研力的整体提升。

常见坑

误用"设置"当"增加"：新手有时想给国家"再加一个槽"，却用了 set_research_slots = 4，结果若该国已有 4 个槽则毫无效果，若已有 5 个槽则反而会减少槽位。需要增加时应优先使用 add_research_slot。
忽略 scope 检查：此命令只在 COUNTRY scope 下有效，若在 state 或 character 等 scope 中误用，脚本不会报错但命令会被静默忽略，排查时容易遗漏。

Hands-On Notes

Hands-On Usage

set_research_slots is commonly used after focus completion, event triggers, or when specific conditions are met to directly set a country's research slot count to a target value. For example, it can provide early-game bonuses to a weaker nation or simulate a period of technological surge in a scenario. Unlike commands that only increment a single slot, it is suited for situations requiring "precise total control"—such as fixing research slots to a specific number regardless of the current amount.

# Set research slots to 5 upon focus completion
focus = {
    id = SCI_research_boom
    ...
    completion_reward = {
        set_research_slots = 5
    }
}

Synergy

[add_research_slot](/wiki/effect/add_research_slot) — Complementary tools: set_research_slots provides exact total assignment, while add_research_slot increments based on the current value. Combined, they enable "reset then stack" workflows.
[amount_research_slots](/wiki/trigger/amount_research_slots) — Condition checking: Before executing set_research_slots, use this trigger to verify the current slot count and avoid unexpectedly reducing slots the player may have gained through other means.
[add_ideas](/wiki/effect/add_ideas) — Research slot changes are often paired with national spirits. Use add_ideas to simultaneously grant ideas that provide research bonuses, forming a complete research enhancement package.
[add_tech_bonus](/wiki/effect/add_tech_bonus) — Common companion in the same scenario: while setting slot count, grant research acceleration for specific technologies to simulate an overall boost to national research capability.

Common Pitfalls

Confusing "set" with "add": Beginners sometimes intend to give a country "one more slot" but use set_research_slots = 4, resulting in no effect if the country already has 4 slots, or reducing slots if it already has 5. When incrementing, prioritize add_research_slot.
Neglecting scope validation: This command only works in COUNTRY scope. If misused in state or character scopes, the script will not error but the command is silently ignored—a trap easy to miss during debugging.
