cocos creater改变父节点，显示的位置不改变（代码里）

//var huapin = childs[3].getChildByName('k').children[0]

//          var pos1 = huapin.convertToWorldSpaceAR(cc.p(0,0));
//            var pos2 = this.node.convertToNodeSpaceAR(pos1);
            
  //          huapin.setPosition(pos2)
    //        huapin.parent = this.node

 function changeParent(node, parent){
            var pos1 = node.convertToWorldSpaceAR(cc.p(0,0));
            var pos2 = parent.convertToNodeSpaceAR(pos1);
            node.setPosition(pos2)
            node.parent = parent
        }
