如何阻止物品返回原位

Question

这是一个拖放匹配游戏，我的问题是当我匹配错误时，如何阻止项目返回到原来的位置？我希望这些物品留下来。请为我详细解释，不胜感激。

您应该从每个发布函数中删除else条件。更新代码如下：

    right_mc.visible=false; 
    wrong_mc.visible=false;
    var orig1X:Number=item1_mc.x;  
    var orig1Y:Number=item1_mc.y;
    var orig2X:Number=item2_mc.x;
    var orig2Y:Number=item2_mc.y;
    var orig3X:Number=item3_mc.x;
    var orig3Y:Number=item3_mc.y; 
    item1_mc.addEventListener(MouseEvent.MOUSE_DOWN, dragTheObject);
    item1_mc.addEventListener(MouseEvent.MOUSE_UP, item1Release);
    item2_mc.addEventListener(MouseEvent.MOUSE_DOWN, dragTheObject);   
    item2_mc.addEventListener(MouseEvent.MOUSE_UP, item2Release);   
    item3_mc.addEventListener(MouseEvent.MOUSE_DOWN, dragTheObject);    
    item3_mc.addEventListener(MouseEvent.MOUSE_UP, item3Release);    
    done_btn.addEventListener(MouseEvent.CLICK, checkAnswers);    
    reset_btn.addEventListener(MouseEvent.CLICK, reset);
    item1_mc.buttonMode=true;    
    item2_mc.buttonMode=true;    
    item3_mc.buttonMode=true;

    function dragTheObject(event:MouseEvent):void 
    { 
        var item:MovieClip=MovieClip(event.target); 
        item.startDrag();

        if (dropZone1_mc.hitTestPoint(item.x,item.y))
        { 
            item.x=dropZone1_mc.x; 
            item.y=dropZone1_mc.y; 
        }

        { 
            item.x=dropZone2_mc.x; 
            item.y=dropZone2_mc.y; 
        }
    }    
    function item3Release(event:MouseEvent):void 
    { 
        var item:MovieClip=MovieClip(event.target);
        item.stopDrag();
        if (dropZone3_mc.hitTestPoint(item.x,item.y))
        {
            item.x=dropZone3_mc.x;
            item.y=dropZone3_mc.y;
        }
    } 
    function checkAnswers(event:MouseEvent):void 
    {
        if (dropZone1_mc.hitTestPoint(item1_mc.x,item1_mc.y) &&
        dropZone2_mc.hitTestPoint(item2_mc.x,item2_mc.y) &&

        {
            wrong_mc.visible = false;
            right_mc.visible = true;
        } 
        else 
        {
            wrong_mc.visible = true;
            right_mc.visible = false;
        }
    }
    function reset(event:MouseEvent):void {
        item1_mc.x=orig1X;
        item1_mc.y=orig1Y;
        item2_mc.x=orig2X;
        item2_mc.y=orig2Y;
        item3_mc.x=orig3X;
        item3_mc.y=orig3Y;
        right_mc.visible=false;
        wrong_mc.visible=false;
    }
