呼叫方式
Core.point_conditions.pointIdentity(self, unit, key)
記錄相依項目 Core.point_conditions.pointIdentity,然後以該名稱呼叫。含命名空間的呼叫不會傳入 self:請使用冒號呼叫,或自行傳入該物件。
作用
Observes whether unit exists and, if so, its class, for the point-resource selectors. For the player it reuses a class stored in self.longtermCache under key when it was recorded against the same UnitClass function, and otherwise stores the freshly read class there.
參數
| 名稱 | 類型 | 作用 |
|---|---|---|
self | RMAddon | Rotation Master addon instance. |
unit | string | Unit token to observe. |
key | any | Long-term cache key for the player's class; only used for "player". The addon passes a private table. |
傳回值
| 1 | table | nil | {exists=false}, or {exists=true, class=token}; nil when unavailable. |
|---|---|---|
| 2 | string | nil | The platform observer's reason for nil. |
版本
內建輔助函式在每個版本上都會註冊。不同的是它們讀取的遊戲 API;某個 API 不存在時,輔助函式會改用備用方式,或傳回 nil 並附上原因。
- 該版本無法使用(原因請見提示)
- 僅在暴雪的棄用相容層開啟時

機密值(正式版與永久)
在正式版與永久上,遊戲交給插件的是機密值。此輔助函式會檢查它讀取的內容(addon.Platform:CanReadValue),遇到無法比較的機密值時,會傳回 nil 並附上原因(例如 restricted-value),而不是傳回該機密值。請將 nil 視為無法使用,而非假。
範例
-- needs the dependency Core.point_conditions.pointIdentity
local record, reason = Functions.cache.getCached(cache, Core.point_conditions.pointIdentity, addon, "target")
if not record then return nil, reason end
return record.exists and record.class == "ROGUE"原始碼
Core/point_conditions.lua,第 27 行。在遊戲中為唯讀;「複製」會產生一份可編輯的複本。
Core.point_conditions.pointIdentity(self, unit, key)

local nativeClass=UnitClass
local longterm=self.longtermCache
if not platform:CanReadValue(longterm) or type(longterm)~='table' then longterm=nil end
