AndEngine进阶之自定义Tiled精灵.docx

1、AndEngine进阶之自定义Tiled精灵AndEngine内置了一个TiledSprite类，可以传入TiledTextureRegion的纹理以构造一个可以连续播放的精灵，但必须要先制作好一张动画序列图片，俗称Tiled图。但有时候在游戏项目开发中，美术人员本来的工作量已经很大，而且这种Tiled在需要修改时也带来了工作量。在IPhone的cocos2d里的精灵类有一个runAction的方法可以播放一组序列图片以达到动画功能，但这种方式在使用的时候稍嫌麻烦，于是我封装了一个自定义Tiled精灵类。view plain1. packagecom.weedong.sprite;2. 3.
