【引擎触发】装备穿戴：换装属性重算与装备位校验的引擎实现

---穿戴：校验通过后走引擎接口
function Equip.wear(actor, where, makeIndex)
    local item = Equip.locate(actor, makeIndex)
    if not item then
        sendmsg(actor, 1, "物品不存在或已失效")
        return false
    end
    local def = Equip.defOf(item)
    if def.needLevel and actor:GetLevel() < def.needLevel then
        sendmsg(actor, 1, "等级不足，需 " .. def.needLevel .. " 级")
        return false
    end
    if def.needJob and not Equip.jobOk(actor, def.needJob) then
        sendmsg(actor, 1, "职业不符")
        return false
    end
    takeonitem(actor, where, makeIndex)
    sendmsg(actor, 1, "已装备 " .. item:GetName())
    return true
end

---卸下：背包空间校验加引擎接口
function Equip.unwear(actor, where, makeIndex)
    if not Equip.bagHasSpace(actor) then
        sendmsg(actor, 1, "背包已满，无法卸下")
        return false
    end
    takeoffitem(actor, where, makeIndex)
    sendmsg(actor, 1, "已卸下装备")
    return true
end
