实现用滑块控制图片缓动左右播放的功能

Flash  as中用滑块mc控制的pic_mc的图片缓动播放的制作

代码如下:
left = bar_mc._x+dragBox_mc._width/2;
right = bar_mc._x+bar_mc._width-dragBox_mc. _width/2;
bottom = top=bar_mc._y;
//确定滑块可移动的左右及上下边界
this.dragBox_mc.onPress = function() {
    this.startDrag(true,left,top,right,bottom);
    box_mc.onEnterFrame = function() {
        var _posX:Number = (dragBox_mc._x-left)/(right-left)*(mask._width-this._width)+mask._x;
        this._x += (_posX-this._x)*.2;
        Math.abs(_posX-this._x)<.2 && delete this.onEnterFrame;
    };
};
this.dragBox_mc.onRelease = this.dragBox_mc.onReleaseOutside=function () {
    this.stopDrag();
};
