调用方式
Conditions.weapon.enchantObservation(value, cache)
记录依赖项 Conditions.weapon.enchantObservation,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 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.
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 | 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
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
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。
插件如何调用它
源码
Conditions/weapon.lua,第 60 行。在游戏中为只读;“复制”会生成一份可编辑的副本。
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
