[要求]
按下鼠标拖动图片缓冲放大并移到最前面，松开鼠标停止拖动图片缓冲缩小。
[步骤]
导入几张图片分别转为影片元件，拖到主场景，实例名分别为pic0_mc、pic1_mc、pic2_mc……在帧上写如下代码：
for (var d:Number = 0; d<=2; d++) {
this["pic"+d+"_mc"].onPress = function() {
mx.behaviors.DepthControl.bringToFront(this);//移到最前
startDrag(this);
this.onEnterFrame = function() {
this._xscale += (200-this._xscale)/4;//缓冲放大
this._yscale += (200-this._yscale)/4;
if (this._xscale>=200) {
delete this.onEnterFrame;
}
};
};
this["pic"+d+"_mc"].onRelease = function() {
stopDrag();
this.onEnterFrame = function() {
this._xscale -= (this._xscale-100)/4;//缓冲缩小
this._yscale -= (this._yscale-100)/4;
if (this._xscale<=100) {
delete this.onEnterFrame;
}
};
};
}
