在框架中找到CustomSettings，新增：

_GT(typeof(EventTriggerListener)),

重新生成Wrap。
編寫lua程式碼：

--主入口函式。從這裡開始lua邏輯

require "Common/define"

function Main()                 
    AddEvent();
end

--場景切換通知
function OnLevelWasLoaded(level)
    Time.timeSinceLevelLoad = 0
end

function AddEvent()
    local btn=GameObject.Find("btn");
    EventTriggerListener.Get(btn).onPointerClick = EventTriggerListener.Get(btn).onPointerClick+Onclick;
end

function Onclick(obj)
    print('lua click trigger! from GameObject:'.. obj.name);
end

在define.lua中需新增

EventTriggerListener = LuaFramework.EventTriggerListener;

大功告成，筆者也是剛剛接觸LuaFramework，博文只是作為學習筆記與大家分享，希望能與大家共同進步。

好了，祝進步。

每天進步一點點。
