gaia note

Q:偵測目前的scene
A:var myParentSrc:String = page.branch;//取得paga路徑 ex:index/nav/home


if(ExternalInterface.available){//只有ExternalInterface可用时才执行JS调用。
Tracking.track(“alert”, route);
}


Q:一開始發布甚麼都沒有居然會自己有背景!!
A:new Scaffold(this);這行註解調


Q:左上角的menu如何刪除
A:先刪除每個page的new Scaffold(this);這行，再把Scaffold.swf刪掉


Q:換頁中間的loading哩?
A:跟一開始LOADING依樣


Q:取得上一層的路徑 
A:var myParentSrc:String = page.getParent().src;//但是nav= =


Q:直接去某一頁
A:Gaia.api.goto("index/nav/about");


Q:右鍵不要menu
A:<site title="Gaia Framework Site: %PAGE%" menu="false">//menu設為false


Q:除了page nav跟preloading切開?!不能直接發!?
A:放在INDEX.FLA(待測，MAIN等於一個LOADER


Q:preloader一直是黑色的！？
A:一切都是誤會!!沒有什麼顏色效果設定需要改，把場景上的刪掉再重新拉出來就變彩色的了...

Q:一執行一片空白!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
A:可以用ADDED_TO_STAGE來載入 BUT仍有一些問題
或是寫隻CLASS!(待測...
如果用ADDED_TO_STAGE來載入除了preloader跟nav有些問題之外，其他page好像ok

Q:menu 跑的影格名稱找不到!
A:無解!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
用原始方法解決吧.........
