详细描述

Read-only EvaluationContext backed by one card instance and definition.

Both pointers are borrowed only for the synchronous evaluate call. Card attributes expose the definition's cost/attack/health, while resource, authority and policy lookups are supplied by the owning game/profile.

构造及析构函数说明

CardPlayConditionContext()

eve::card::CardPlayConditionContext::CardPlayConditionContext	(	const CardData *	card,
		const CardDefinition &	definition,
		CardPlayConditionQueries	queries = {}
	)

Bind a card instance and definition for one evaluation.

参数

card	Borrowed card instance; it must outlive the evaluation call.
definition	Borrowed definition; it must outlive the call.
queries	Optional read-only providers for external capabilities.
