详细描述

EvaluationContext backed by one borrowed RPG actor and SkillDefinition.

The actor and definition are observed only for the synchronous call to Condition::evaluate; this context does not own or retain them beyond that call. Attributes and resource amounts are read from the canonical AttributeSet. Tags include both skill-definition tags and active RPG status tags.

构造及析构函数说明

SkillConditionContext()

eve::rpg::SkillConditionContext::SkillConditionContext	(	const RPGActor *	actor,
		const SkillDefinition &	definition,
		SkillConditionQueries	queries = {}
	)

Bind a read-only actor/skill pair for one synchronous evaluation.

参数

actor	Borrowed actor; it must outlive the evaluation call.
definition	Borrowed skill definition; it must outlive the call.
queries	Optional read-only authority and policy providers.
