例如子弹打飞机的程序，怎样判断子弹是否打中飞机（子弹进入飞机所在的区域），最好给出原代码。 请给位指教。

A fast and simple way for doing collision detection is using the bounding rectangles of the spriates and test whehter they are overlapped or not. If you don't want to write your own function, you may be interested in the IntersectRect API. If you want to do a pixel perfect collision detection, I think you would better create masked mono bitmaps for all your spriates and use the masks for collision detecton.

感谢你的回答，不过不是太详细，我知道原理，问题是具体的实现方法，最好给出代码参考，还有希望用中文交流。这个问题本人仍没解决，希望有心人多多指教。

本人知道可以用 Rect()函数 PtinRect()函数 来实现，但具体参数如何给（image的两个顶点，和目标区域的给定点的参数值) 我还没搞明白

這回到我糊塗了，Sprites 應是你用程式秀出來的吧，它的區域(bounding recentangle)你應該一早便掌握了 在子彈打飛機類的游戲上，我想簡單的區域碰撞測試應可滿足要求， < href="http://www.gamedev.net/reference/articles/article735.asp">http://www.gamedev.net/reference/articles/article735.asp
