Conditions.build.imbueObservation

调用方式

Conditions.build.imbueObservation(value, cache)

记录依赖项 Conditions.build.imbueObservation，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 temporary enchant ID on the main hand, or the off hand when value.offhand is set, for the WEAPON_IMBUE condition. Uses the cached GetWeaponEnchantInfo, or the platform's composed reader on clients with C_PaperDollInfo.GetTemporaryEnchantmentInfo, and returns false when that hand has no temporary enchant.

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`	Enchant ID of the temporary enchant, false when the hand has none, or nil when it cannot be read.
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。

该版本不可用（原因见提示）
仅在暴雪的弃用兼容层开启时

游戏 API
`C_PaperDollInfo.GetTemporaryEnchantmentInfo`
`GetWeaponEnchantInfo`

秘密值（正式服和永久服）

在正式服和永久服上，游戏交给插件的是秘密值。此辅助函数会检查它读取的内容（addon.Platform:CanReadValue），遇到无法比较的秘密值时返回 nil 并附上原因（例如 restricted-value），而不是返回该秘密值。请将 nil 视为不可用，而不是假。

源码

Conditions/build.lua，第 88 行。在游戏中为只读；“复制”会生成一份可编辑的副本。

Conditions.build.imbueObservation(value, cache)

    local reader = GetWeaponEnchantInfo
    if C_PaperDollInfo and C_PaperDollInfo.GetTemporaryEnchantmentInfo then reader = addon.Platform.ComposedWeaponEnchantInfo end
    if type(reader) ~= "function" then return nil, "missing-api" end
    ---@diagnostic disable-next-line: unbalanced-assignments
    local ok, main, _, _, mainID, off, _, _, offID = pcall(Functions.cache.getCached, cache, reader)
    if not ok then return nil, "api-error" end
    local enchanted, id = main, mainID
    if value.offhand then enchanted, id = off, offID end
    if not addon.Platform:CanReadValue(enchanted) or not addon.Platform:CanReadValue(id) then return nil, "restricted-value" end
    if enchanted == nil or enchanted == false or enchanted == 0 then return false end
    if type(id) ~= "number" then return nil, "invalid-weapon-observation" end
    return id
