这一段写成AS3应该怎么写啊，急求

var muover:Number = 0; var muout:Number = 0; var muclick:Number = 1; for (var i:Number = 1; i<6; i++) { this["btn"+i].bg._visible = 0; this["btn" + i].bg.stop(); this["btn"+i].num = i; this["btn"+i].btn.onRollOver = function() { muover = this._parent.num; }; this["btn"+i].btn.onRollOut = function() { muover = muout; }; this["btn"+i].onEnterFrame = function() { if (this.num == muover) { this.nextFrame(); } else { this.prevFrame(); } if (this.num == muclick) { this.bg._visible = 1; this.bg.play(); } }; this["btn"+i].btn.onRelease = function() { this._parent.bg._visible = 1; this._parent.bg.gotoAndPlay(1); this._parent._parent["btn"+muclick].bg.gotoAndStop(1); this._parent._parent["btn"+muclick].bg._visible = 0; muclick = this._parent.num; this._parent._parent["img"].gotoAndPlay("m"+muclick); }; }
 提示：您可以先修改部分代码再运行
