【引擎触发】magtagfunc：对目标施法的联动钩子

---magtagfunc(X): 对目标人物使用技能触发
---以群体治疗术（技能 ID 24）为例
function magtagfunc24(self, roleObject)
    local player = class(self)
    if not player then return end
    local target = getplayerbyname(roleObject)
    if not target then return end
    -- 治疗的联动：附带清除一个中毒状态
    local poisoned = getplayvar(roleObject, 2, "Poisoned")
    if poisoned and poisoned ~= "" then
        setplayvar(roleObject, "HUMAN", "Poisoned", "", 1)
        sendmsg(roleObject, 1, "中毒状态被驱散")
        sendmsg(self, 1, "毒素已被治疗驱散")
    end
end

---施毒术（技能 ID 13）的毒源记录
function magtagfunc13(self, roleObject)
    local player = class(self)
    if not player then return end
    -- 记录毒源：谁在何时施的毒
    setplayvar(roleObject, "HUMAN", "PoisonedBy",
        player:GetName(), 0)
    setplayvar(roleObject, "HUMAN", "PoisonedAt",
        os.time(), 0)
    sendmsg(self, 1, "施毒成功，目标已中毒")
end
