一款接球游戏,游戏中使用DirectX 7，图形较为流畅，每秒高达50桢。具有较高的计算机人工智能.英文介绍：DX pong is a neat pong game that uses DirectX 7. I wrote it in just one day and the graphics are smooth - over 50 fps! There are sound FX too, but the best thing about the game is the computer AI. It doesn t simply chase the ball, it predicts the balls path even if it is going to bounce of several walls and moves accordingly. Clever AI doesn t mean it is impossible to beat - it means it acts like a human player making the game more fun. So - have fun!-DX pong is a neat pong game that uses DirectX 7.
