[AS3]TweenMax的围绕中心点旋转实例

新建一个sprite作为一个container，通过target.parent来替换target的位置和x,y
然后target坐标归0,0
container.addChild(target);

两个tweenMax，一个旋转target，一个移动container

override protected function doEffect():void{ 
                        if(this.target.parent!=null){ 
                                container=new Sprite(); 
                                container.x=this.target.x; 
                                container.y=this.target.y; 
                                 
                                this.target.parent.addChildAt(container,this.target.parent.getChildIndex(this.target)); 
                                container.addChild(this.target); 
                                this.target.x=0; 
                                this.target.y=0; 
                                 
                                TweenMax.to(container,time-0.1,{x:x,y:y}); 
                                 
                                TweenMax.to(target,time,{ease:Cubic.easeOut,transformAroundCenter:{ 
                                        rotation:(round*360*direction) 
                                },onComplete:completeHandler}); 
                                 
                        }else{ 
                                 
                                TweenMax.to(target,time,{ease:Cubic.easeOut,transformAroundCenter:{ 
                                        rotation:(round*360*direction) 
                                },x:x,y:y,onComplete:completeHandler}); 
                                 
                        } 
 
                } 
                 
                private function completeHandler():void{ 
                        if(container!=null){ 
                                container.parent.addChildAt(this.target,container.parent.getChildIndex(container)); 
                                this.target.x=container.x; 
                                this.target.y=container.y; 
                        } 
                        container=null; 
                         
                        effectComplete(); 
                }
