Question

出于某种原因，我的所有精灵都开始出现在黑盒子之前。这是我的代码。我只使用前2个精灵运行良好，但当我添加其他精灵时，他们在我的Android设备上变成了黑盒子。任何帮助将不胜感激。

Answer 1

我认为您需要在onCreateResources（）方法的末尾添加此内容

this.mBitmapTextureAtlas.load();

Answer 2

问题是你的所有图像都比纹理图集大。这与地图集的整个表面无关。地图集可能有更大的表面，但是根据纹理的大小和形状，它可能无法将它们全部添加到其中，并且无法加载。

我可以告诉你，因为你说它可以正常工作，直到你添加另一个。尝试使您的纹理图集更大或更好，创建另一个纹理图集并在那里添加其他精灵。

我遇到了这个问题，发现问题就在于此。

希望它有所帮助！

Answer 3

这可能与此问题有关：Issue 53: BitmapTextureAtlasTextureRegionFactory.createTiledFromAsset can not find bitmap files when file has underscores in the name

Answer 4

检查

您的Atlas已加载
如果您在场景变换期间装载和卸载了地图册，请确保再次装入地图册。
图像的大小。图像尺寸不应超过2048 * 2048.尺寸大于此尺寸会在不同设备（高分辨率设备）中产生问题。
