问题描述
我开发一个小的Android游戏。之前，我开始使用AndEngine，我使用Canvas对象并在其上绘制的一切。为了进行测试，如果两个位图碰撞彼此，如果他们的边框重叠我检查。在这种情况下，我检查如果这两个位图重叠矩形共同得到了一个没有透明像素。
这种方法perfektly工作，我能够检测像素的完美碰撞。
I am developing a small Android game. Before I started using AndEngine, I used the Canvas object and draw everything on it. For testing if two bitmaps collides with each other I checked if their bounding boxes overlap. In case of this, I checked if the overlapping rectangle of both bitmaps got one none transparent pixel in common.This method worked perfektly and I was able to detect pixel perfect collisions.
因为我开始使用AndEngine一些性能问题。碰撞检测安静的工作很好，但是碰撞测试有两个精灵definitly dosent工作完美像素。在碰撞测试只是一个边界框测试。
Because of some performance issues I started using AndEngine. Collision detection works quiet good but collision tests for two sprites definitly dosent work pixel perfect. The collision tests is "just" a bounding box test.
推荐答案
下面是像素完善的检测一个很好的例子，
Here is a nice example of pixel perfect Detection,
