【入门夯实】Lua type判定：祖玛教主对话的参数类型闸门

local function onTalk(actor, task)
    if task.step >= 3 then           -- task为字符串时当场炸
        sendmsg(actor, 1, "可挑战祖玛教主")
    end
end

local function onTalk(actor, task)
    if type(task) ~= "table" then    -- 类型闸门先收口
        sendmsg(actor, 1, "任务数据异常，请重新接取")
        return
    end
    if task.step >= 3 then
        sendmsg(actor, 1, "可挑战祖玛教主")
    end
end
