--定义模块

    AllLuaBehaviourList = List:New(),
    AllLuaBehaviourDic = Dictionary:New(),
    UpdateLuaBehaviourList = List:New(),
}

--给对象添加LuaBehaviour组件，并关联对应的模块
function LuaBehaviourManager:Add(trans, table)
    if self.AllLuaBehaviourDic:ContainsKey(table) then
        return
    end
    local _luaBehaviour = UnityUtils.RequireLuaBehaviour(trans);
    self.AllLuaBehaviourList:Add(_luaBehaviour);
    self.AllLuaBehaviourDic:Add(table, _luaBehaviour);

    table._ActiveSelf_ = trans.gameObject.activeSelf;

    table._OnDestroy_ = function(obj)
        if obj.OnDestroy then
            obj:OnDestroy();
        end
        self:Remove(obj);
    end

--LuaBehaviour组件销毁时，自动移除

    end
end

function LuaBehaviourManager:Update(deltaTime)
    for i=1,self.UpdateLuaBehaviourList:Count() do
        if self.UpdateLuaBehaviourList[i]._ActiveSelf_ then
            self.UpdateLuaBehaviourList[i]:Update(deltaTime);
        end
    end
end
