Just forgot to mention that I made a blog for my new prefix “professor” in Kean university.

If you are interested in learning flash or checking out some AS3 for Flash IDE example I used in class, you can go to mediamultimedia.wordpress.com

If you are pretty new to Flash / AS3, there are some Flash IDE based examples in class blog for people to download.

If you want to build something like keyboard shortcut or want to catch global mouse activity, you might need to use

stage.addEventListener(KeyboardEvent.KEY_DOWN,onKeyPressed);
//or
stage.addEventListener(MouseEvent.CLICK,onMouseClicked);

You might need to access “stage” from sub-classes. To get “stage” from document class you can try:

addEventListener(Event.ADDED_TO_STAGE, onAddStage);
private function onAddStage(evt:Event):void{
//var myParent:Sprite=Sprite(evt.target)
//myParent.stage.addEventListener(KeyboardEvent.KEY_DOWN,onKeyPressed);
//sprite裡面的stage property 已經可以因為被放到Stage的事件之後被使用
this.stage.addEventListener(KeyboardEvent.KEY_DOWN,onKeyPressed);
}

如果今天new一個DisplayObject然後reference給一個property variable,addChild,之後 removeChild 然後那個property variable又reference給另一個DisplayObject.

那原先的DisplayObject就再也access不到了對吧？ 這樣子Garbage Collection會釋放出記憶體嗎？

不管有沒有 把 reference 先設成 null,再重新 reference, GC都會把他清掉.只是快慢問題而已.好像沒有記憶體越用越多的問題….

ex:

b=new SpriteClassA();

a.addChild(b);

b.remove()//自己fadeout之後 parent.removeChild(this)

b=new SpriteClassB();

a.addChild(b);
