我有一个简单的功能，当你点击一个按钮，添加一个随机的X和Y位置的影片剪辑的舞台。我遇到的问题是，新的影片剪辑最终掩盖按钮。我试图改变新创建的MC的z索引是按钮的z索引下面，但这并没有解决问题。怎样才能阻止新的三菱商事的，从覆盖了一个已经存在的元素。

  friends1_btn.addEventListener（MouseEvent.CLICK，friendMaker）;

功能friendMaker（EVT：MouseEvent）方法：无效{
    VAR newFriend：泰迪=新泰迪（）;
    newFriend.x =的Math.random（）* stage.width;
    newFriend.y =的Math.random（）* stage.height;
    newFriend.z = 0;
    stage.addChild（newFriend）;
}
 

解决方案

或者可以选择 - 也许更长期的使用 - 没有所有添加的对象为同一层的按钮，儿童

所以：

 阶段
  |
  + ---对象1
  |
  +  - 对象2
  |
  +  - 键
  |
  + ---对象3
 

有：

 阶段
  |
  + ---对象层
  | |
  | + ---对象1
  | |
  | +  - 对象2
  |
  +  - 键
 

甚至

 阶段
  |
  + ---对象层
  | |
  | + ---对象1
  | |
  | +  - 对象2
  |
  +  - 按键层
          |
          +  - 键
 

其中，对象层和按钮层可能仅仅是雪碧对象，即：

  VAR objectLayer：雪碧=新的Sprite（）;
VAR buttonLayer：雪碧=新的Sprite（）;
stage.addChild（objectLayer）;
stage.addChild（buttonLayer）;
buttonLayer.addChild（myButton的）;
 

等等。

我想你会发现它更有助于进入长期的思考，而不是仅仅围绕转变的z指数的方式。

顺便说一句，更新的Flash Player 10中的确实的有 .Z 属性（即使它不是在文档中） - 为鲁本说，它使用新的3D转换。可悲的是3D转换没有任何支持的Z分类或Z层次感，所以不要在这种情况下提供帮助。

I have a simple function that, when you click on a button, adds a movie clip to the stage in a random x and y position. The issue I am having is that the new movie clips eventually cover up the button. I tried to change the z-index of the newly created mc to be below the z-index of the button, but that doesn't solve the problem. How does one stop the new mc's from covering up an element that already exists.

    friends1_btn.addEventListener(MouseEvent.CLICK, friendMaker);

function friendMaker(evt:MouseEvent):void {
    var newFriend:Teddy = new Teddy();
    newFriend.x = Math.random()*stage.width;
    newFriend.y = Math.random()*stage.height;
    newFriend.z = 0;
    stage.addChild(newFriend);
}

Or alternatively - and maybe more use longterm - don't have all the added objects as children of the same layer as the button.

So instead of:

stage
  |
  +--- object 1
  |
  +--- object 2
  |
  +--- button
  |
  +--- object 3

Have:

stage
  |
  +--- object layer
  |       |
  |       +--- object 1
  |       |
  |       +--- object 2
  |
  +--- button

Or even:

stage
  |
  +--- object layer
  |       |
  |       +--- object 1
  |       |
  |       +--- object 2
  |
  +--- button layer
          |
          +--- button

Where object layer and button layer could simply be Sprite objects, i.e.:

var objectLayer:Sprite=new Sprite();
var buttonLayer:Sprite=new Sprite();
stage.addChild(objectLayer);
stage.addChild(buttonLayer);
buttonLayer.addChild(myButton);

and so on.

I think you'll find it's more useful to get into that way of thinking longterm rather than just to shift the z-indices around.

Incidentally, the updated Flash Player 10 does have a .z property (even though it's not in the documentation) - as Reuben says, it's used for the new 3D transforms. Sadly 3D transforms have no support whatsoever for z-sorting or z layering, so don't help in this case.
