trigger · pc_is_state_claimed

Hands-On Usage

pc_is_state_claimed is commonly used in mod scenarios related to peace conferences, such as post-war peace conference or territorial allocation systems, where it determines whether a state has been claimed by a party without dispute, thereby deciding whether to allow further diplomatic or construction actions. A typical scenario is using it within an available block to restrict a decision so it can only be triggered when the current state has been claimed without dispute.

# Using within a decision available block scoped to STATE
available = {
    pc_is_state_claimed = yes
    is_owned_by = ROOT
}

Synergy

• [pc_is_state_claimed_by](/wiki/trigger/pc_is_state_claimed_by): Can be used in conjunction to further precisely determine which country made the claim after confirming the state is claimed, resulting in more rigorous logic.
• [has_contested_owner](/wiki/trigger/has_contested_owner): pc_is_state_claimed checks for "uncontested" claims; pairing it with this trigger allows you to distinguish between contested and uncontested states, building more complete conditional branches.
• [is_owned_by](/wiki/trigger/is_owned_by): Claims and actual control are two different things; typically you need to confirm both the state's ownership and claimed status to avoid logical gaps.
• [add_claim_by](/wiki/effect/add_claim_by): When used together in an effect block, if claim conditions are not met, you can use this effect to add claims, forming a complete "check → remedy" workflow.

Common Pitfalls

1. Confusing "claims" with "cores": Beginners often conflate pc_is_state_claimed with [is_core_of](/wiki/trigger/is_core_of), but the former is specific to the Peace Conference system context. Using it outside peace conference flows may always return false, rather than the expected territorial ownership judgment.
2. Overlooking the "uncontested" requirement: This trigger requires that the claim be uncontested; if a state is claimed by multiple parties with disputes, the result is false. If you only use it to check "whether anyone claimed it" without considering disputes, you may encounter unexpected logic errors. In such cases, pair it with [has_contested_owner](/wiki/trigger/has_contested_owner) for supplementary checks.
