AndEngine視差背景上的動畫小精靈幫助！ :)

Question

嗨，我的名字是喬納斯，我正在參加Android編程大學課程。 我總是不得不採取艱難的方式去AndEngine。

在上面的圖片中，你可以看到我使用三層的視差背景。 我正在製作一個sidescroller，所以最後一層是藍色線條，這是一條冰跡。我想爲這張照片製作動畫並將其放在曲目上。

當我爲我是在模擬器apeshit會和我展示在屏幕一角的照片的小三角形以同樣的方式動畫的研究背景動畫兩人加載它。一個動畫的作品是這個：

是我的動畫馬大的圖片或者是別的東西我做錯了。關於這件事，我在互聯網上找不到太多東西！我真的很感激我能得到的所有幫助！

這是我的代碼的一個例子，我知道它是一個ripoff ofEngine的例子，但我在這裏學習。

您使用的是相同的textureatlas同時生成的紋理。這裏是你的紋理圖案定義：

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

他們Y尺寸那裏（128）對於這張圖片太小了。相反，爲玩家圖像製作第二張紋理圖集，至少有256個高度（它需要2的冪次），它會覆蓋它。

另外，我想確保你故意這樣做：

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

這些最後兩個數字（3,4）代表列和你的馬spritesheet的行數。但是，當我看着你的馬，我只有三看三，不是三四個：

這可能是你想要的是空格作爲動畫三個額外的電池，但要確保你這樣做的目的。 createTiledFromAsset（）方法假定精靈在網格中適合。
