AndEngine视差背景上的动画小精灵帮助！ :)

Question

嗨，我的名字是乔纳斯，我正在参加Android编程大学课程。 我总是不得不采取艰难的方式去AndEngine。

在上面的图片中，你可以看到我使用三层的视差背景。 我正在制作一个sidescroller，所以最后一层是蓝色线条，这是一条冰迹。我想为这张照片制作动画并将其放在曲目上。

当我为我是在模拟器apeshit会和我展示在屏幕一角的照片的小三角形以同样的方式动画的研究背景动画两人加载它。一个动画的作品是这个：

是我的动画马大的图片或者是别的东西我做错了。关于这件事，我在互联网上找不到太多东西！我真的很感激我能得到的所有帮助！

这是我的代码的一个例子，我知道它是一个ripoff ofEngine的例子，但我在这里学习。

您使用的是相同的textureatlas同时生成的纹理。这里是你的纹理图案定义：

this.mBitmapTextureAtlas = new BitmapTextureAtlas(this.getTextureManager(), 256, 128, TextureOptions.BILINEAR); 

他们Y尺寸那里（128）对于这张图片太小了。相反，为玩家图像制作第二张纹理图集，至少有256个高度（它需要2的幂次），它会覆盖它。

另外，我想确保你故意这样做：

this.mPlayerTextureRegion = BitmapTextureAtlasTextureRegionFactory.createTiledFromAsset(this.mBitmapTextureAtlas, this, "player.png", 0, 0, 3, 4); 

这些最后两个数字（3,4）代表列和你的马spritesheet的行数。但是，当我看着你的马，我只有三看三，不是三四个：

这可能是你想要的是空格作为动画三个额外的电池，但要确保你这样做的目的。 createTiledFromAsset（）方法假定精灵在网格中适合。
