Conditions.weapon.swingSpeed

调用方式

Conditions.weapon.swingSpeed(value, cache)

记录依赖项 Conditions.weapon.swingSpeed，然后按该名称调用。带命名空间的调用不会传入 self：请使用冒号调用，或自行传入该对象。

作用

Reads the player's main-hand, or off-hand when value.offhand is set, attack speed from the cached UnitAttackSpeed for the swing timer conditions. An off-hand check with no off-hand speed returns false.

参数

名称	类型	作用
`value`	`table`	Condition settings; a truthy offhand field selects the off hand.
`cache`	`table \| nil`	Evaluation-pass cache passed to getCached, or nil to read directly.

返回值

1	`number \| boolean \| nil`	Swing speed in seconds, false when there is no off-hand weapon, or nil when unavailable.
2	`string \| nil`	Reason for nil: missing-api, api-error, restricted-value or invalid-weapon-observation.

版本

内置辅助函数在每个版本上都会注册。不同的是它们读取的游戏 API；某个 API 缺失时，辅助函数会改用后备方案，或返回 nil 并附上原因。

插件如何调用它

武器攻击间隔 (evaluate)

local speed,reason=swingSpeed(value,cache)

武器攻击间隔剩余时间 (evaluate)

local speed,reason=swingSpeed(value,cache)
