用c#如何做二维图像的处理？我只剩下60分了：（
比如，模拟做一个一辆汽车在草原上从东开到西，另外一辆摩托车从西开到东，
这样的事情，用c＃好实现吗？
事实上，我要实现的是不止一辆，有很多汽车到处跑，路线由程序确定，就像游戏里面的那种场景一样。用c#做这样的二维编程好做吗？大家多给点意见好吗？这种程序该怎么做呀？

实际上就是计算某一时间点上,各个图片的显示位置(汽车实际就是一个图片而已)
汽车是一个对象,地图也是一个对象
设计路线就是设计汽车相对地图的移动方式Top

那图片怎么处理后才和背景图片融合的好啊？谁有这方面的例子呀？要用C#的例子，别的没有。
wolfofsky(风之武) 兄弟你的例子给我看一下好吗？Top
