我正在尝试制作一个拖放游戏，其中一个条件是当一个对象被放置到某个位置时，下一步应该会出现。

我对编码非常陌生，而且大部分时间都是盲目的。我创建了这段代码，但我不确定我是否正确编写它以使我的游戏正常运行

  gamefacetemplate.addEventListener(MouseEvent.MOUSE_DOWN, fl_ClickToDrag_2);

function fl_ClickToDrag_2(event:MouseEvent):void
{
    gamefacetemplate.startDrag();
}

gamefacetemplate.addEventListener(MouseEvent.MOUSE_MOVE, fl_ObjectPosition);

function fl_ObjectPosition(event:MouseEvent):void
{
    gamefacetemplate.x = 706.90;
    gamefacetemplate.y = 311.90;
}

gamefacetemplate.addEventListener(MouseEvent.CLICK, fl_MoveToHide_6);

function fl_MoveToHide_6(event:MouseEvent):void
{
    instrustep2.visible = false;
}

stage.addEventListener(MouseEvent.CLICK, fl_ReleaseToDrop);

function fl_ReleaseToDrop(event:MouseEvent):void
{
    gamefacetemplate.stopDrag();
}

{
gamefacetemplate.visible = false;
}

{
    gotoAndStop(5);
}

任何和所有的帮助将不胜感激。

我给你2个例子，我不太了解intrustep对象，所以我把它删除了；）
下面的代码只是用来将gamefacetemplate对象拖到一个位置（我在该位置添加了边距，所以它更灵活）如果你拖动到正确的位置，您转到第 5 帧，否则对象返回到初始位置。所以有两种解决方案：
如果你想拖动定位激活下一步：

gamefacetemplate.addEventListener(MouseEvent.MOUSE_DOWN, fl_ClickToDrag_2);

// maybe you want to keep te original position of the dragin object
var originalPos:Point;

function fl_ClickToDrag_2(event:MouseEvent):void
{
    // keep original position
    originalPos = new Point( gamefacetemplate.x, gamefacetemplate.y );

    // start dragging
    gamefacetemplate.startDrag();

    // listen mouse mouve event
    gamefacetemplate.addEventListener(MouseEvent.MOUSE_MOVE, fl_ObjectPosition);

    // listen mouse up event
    stage.addEventListener(MouseEvent.MOUSE_UP, fl_ReleaseToDrop);
}

function fl_ObjectPosition(event:MouseEvent):void
{
   // test if the object is in a range of acceptable position
   if( gamefacetemplate.x > 650 && gamefacetemplate < 750 && gamefacetemplate.y > 250 && gamefacetemplate.y < 350 )
   {
       // place item at the right position
       gamefacetemplate.x = 706;
       gamefacetemplate.y = 311;

       // stop dragging
       gamefacetemplate.stopDrag();

       // and so remove the listeners
       stage.aremoveEventListener(MouseEvent.MOUSE_UP, fl_ReleaseToDrop);
       gamefacetemplate.removeEventListener(MouseEvent.MOUSE_DOWN, fl_ClickToDrag_2);
       gamefacetemplate.removeEventListener(MouseEvent.MOUSE_MOVE, fl_ObjectPosition);

       // and maybe activate next step
       gotoAndStop(5);
   }
}

function fl_ReleaseToDrop(e:MouseEvent):void
{
    // stop dragging
    gamefacetemplate.stopDrag();

    // replace item at original position
    gamefacetemplate.x = originalPos.x;
    gamefacetemplate.y = originalPos.y;

    // and so remove the listeners
    stage.aremoveEventListener(MouseEvent.MOUSE_UP, fl_ReleaseToDrop);
    gamefacetemplate.removeEventListener(MouseEvent.MOUSE_MOVE, fl_ObjectPosition);
}

或者，如果您希望放置位置激活下一步：

gamefacetemplate.addEventListener(MouseEvent.MOUSE_DOWN, fl_ClickToDrag_2);

// maybe you want to keep te original position of the dragin object
var originalPos:Point;

function fl_ClickToDrag_2(event:MouseEvent):void
{
    // keep original position
    originalPos = new Point( gamefacetemplate.x, gamefacetemplate.y );

    // start dragging
    gamefacetemplate.startDrag();

    // listen for mouse up event
    stage.addEventListener( MouseEvent.MOUSE_UP, fl_ObjectPosition );
}

function fl_ObjectPosition(event:MouseEvent):void
{
    // maybe here you want to stop dragging
    gamefacetemplate.stopDrag();

    // test if the object is in a range of acceptable position
    if( gamefacetemplate.x > 650 && gamefacetemplate < 750 && gamefacetemplate.y > 250 && gamefacetemplate.y < 350 )
    {
       // place item at the right position
       gamefacetemplate.x = 706;
       gamefacetemplate.y = 311;

       // and so remove the listeners
       stage.aremoveEventListener(MouseEvent.MOUSE_UP, fl_ReleaseToDrop);
       gamefacetemplate.removeEventListener(MouseEvent.MOUSE_DOWN, fl_ClickToDrag_2);

       // and maybe activate next step
       gotoAndStop(5);
    }
    else
    {
       // replace item at original position
        gamefacetemplate.x = originalPos.x;
        gamefacetemplate.y = originalPos.y;
    }
}
