如何在Android中使用And引擎将精灵落在另一个上？

Question

你怎么能把一个精灵放在另一个精灵上，如下图所示

你可以看到图像中有两个精灵（1）。顶部的精灵应该放在底部的精灵上，如图（3）所示。我尝试了一些和引擎的例子，但没有得到任何解决方案。如果有人知道如何处理这个问题，请找到一些解决方案或任何来源。谢谢提前

根据编辑附加代码

只需添加此代码！

this.mBadges[1] = new Sprite(0, CAMERA_HEIGHT - 300, this.mBadgeTextureRegion, this.getVertexBufferObjectManager());


scene.attachChild(this.mBadges[1]);
this.mBadges[1].setPosition(positionX, mBadges[0].getY()-mBadges[1].getHeight());

无论你的位置是什么，取而代之的都是。
