呼叫方式
Conditions.weapon.enchantObservation(value, cache)
記錄相依項目 Conditions.weapon.enchantObservation,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
Reads whether the main hand, or the off hand when value.offhand is set, has a temporary weapon enchant for the weapon conditions, with its expiration and charges. Uses the cached GetWeaponEnchantInfo or the platform's composed reader.
參數
| 名稱 | 類型 | 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. |
傳回值
| 1 | boolean | nil | True when enchanted, false when not, or nil when it cannot be read. |
|---|---|---|
| 2 | number | nil | Time until the enchant expires, as the API reports it; only when enchanted. |
| 3 | number | nil | Charges remaining, as the API reports them; only when enchanted. |
| 4 | string | nil | Reason for nil: missing-api, api-error, restricted-value or invalid-weapon-observation. |
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。
插件如何呼叫它
原始碼
Conditions/weapon.lua,第 60 行。在遊戲中為唯讀;「複製」會產生一份可編輯的複本。
Conditions.weapon.enchantObservation(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,nil,nil,"missing-api" end
-- The protected cached API returns both hands' original tuple unchanged.
---@diagnostic disable-next-line: unbalanced-assignments
local ok, main, mainExpires, mainCharges, _, off, offExpires, offCharges = pcall(addon.getCached, cache, reader)
if not ok then return nil,nil,nil,"api-error" end
local enchanted, expires, charges=main,mainExpires,mainCharges
if value.offhand then enchanted,expires,charges=off,offExpires,offCharges end
if not addon.Platform:CanReadValue(enchanted) then return nil,nil,nil,"restricted-value" end
if enchanted==nil or enchanted==false or enchanted==0 then return false end
if enchanted~=true and enchanted~=1 then return nil,nil,nil,"invalid-weapon-observation" end
return true,expires,charges
