[AS3] error 1013 The private attribute may be used only on class property definitions.

#1013 The private attribute may be used only on class property definitions.

In my case, make the private function() contain into the package tag is a solution:
確保把 private的function 包在package裡。

Bad code:

package { import flash.display.*; import flash.events.*; public class zoom_picture2 extends MovieClip { private var itemOfNumber:Number = 10; right_btn.addEventListener(MouseEvent.CLICK,onClickbtn); } } private function onClickbtnl(e:MouseEvent):void { trace("hallo"); }

Good code:

package { import flash.display.*; import flash.events.*; public class zoom_picture2 extends MovieClip { private var itemOfNumber:Number = 10; right_btn.addEventListener(MouseEvent.CLICK,onClickbtn); } private function onClickbtnl(e:MouseEvent):void { trace("hallo"); } }
