マルチタッチのイベントハンドラ

ズームの検出

private someFunction():void{
  ...
  mouse.addEventListener(TransformGestureEvent.GESTURE_ZOOM , onZoom);
  ...
}

private function onZoom(e:TransformGestureEvent):void{
  var m:Sprite = e.target as Sprite;
  m.scaleX = e.scaleX;
  m.scaleY = e.scaleY;
}

回転の検出

private someFunction():void{
  ...
  mouse.addEventListener(TransformGestureEvent.GESTURE_ROTATE , onRotate);
  ...
}

private function onRotate(e:TransformGestureEvent):void{
  var m:Sprite = e.target as Sprite;
  m.rotation += e.rotation;
}
