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回到原来的位置？我希望这些物品留下来。请为我详细解释，将不胜感激。

您应该从每个发布功能中删除 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;
