用Flash AS代码制作鼠标点击图片缓冲放缩动画效果

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;
}
};
};
}
