(建议用WIN-TC编译，会自动加载图形驱动，TC2就要处理了，用VC6不行，有些图形函数不兼容) 我刚较大的改写完善了书上《C语言游戏编程》的一个小C游戏,原来的赛车只能向左或向右,不能前进和后退,而且过路车只有一辆卡车,只有一种颜色,很单调,我增加了赛车的前进和后退,又加了一辆小货车,并加了选择游戏难度的菜单和里程显示,还使过路车的色彩五彩缤纷, 并且,如果赛车从左右两侧撞上过路车,也能反映失败.相比之下,原来的撞车就很单一了,.. 希望大家有时间玩一玩,,,如果美工好的,也可自己改成逼真的车型... 另,也准备好了能独立运行的可执行程序,双击就可玩的...(哎呀! 不能上传吗?) 原代码: #include <math.h> #include <conio.h> #include <stdio.h> #include <stdlib.h> #include <graphics.h> #include <dos.h> #include <bios.h> #include <string.h> #include <ctype.h>

小说明

一， 玩法： 1，一般玩法：

双击car文件，就可运行了。

我电脑的CPU是733Mhz，是在这个频率下用C语言编写的（有兴趣可参看“程序源代码“文件），由于不同电脑的CPU的频率高低不同(较新的电脑的CPU在2000Mhz左右，就是2Ghz)，引起游戏运行速度不同，不过可以通过选择最后一项"自定义方式"运行：（本游戏的快慢主要通过delaytime(延迟时间)决定的，延迟时间越大，游戏就越慢，反之，就越快。建议的基本范围：100 到 10000 。不过，如果CPU过高或过低的话， 也可从 0 到 更高。。。当然也可根据个人的喜好）

选择游戏速度的窗口如下：

h....(high) 高速 a....(average) 平均 l....(low) 低速 c....(coustomize) 自定义速度

可直接按下相应的字母确定，也可先用上下箭头键（或间隔键）选择，再按下回车键确定。 其中，自定义方式可另弹出窗口提示说明（内容就是上面提到的） 在光标处输入从100 到10000 之间的数字，按下回车键确定。（如按下其他键 可能死机，不过不要紧，可同时按ALT和回车键回到小窗口，再关闭。 以后再完善此处的程序。。）

2，另类玩法：（可能有点不协调） 如果游戏速度过快，除了上面提到的自定义方式外，也可用一个程序来使在运行这个游戏的范围里给CPU将速(由于程序是在系统的虚拟DOS窗口运行的，程序运行时跟系统真实的硬件包括CPU等等是毫无关系的。这里的给CPU降速只是在虚拟环境中的，因此不会对真实的CPU作任何改变，更谈不上损伤了。所以请放心。)，程序名叫slowdown.

为了运行方便，我编写了运行程序的批处理文件play, 可根据情况，自由设定运行程序的CPU频率。

具体方法： 1），右键play程序名，编辑，slowdown /p:30 处的30是百分比数，表示以30%的CPU频率运行程序，你可自由设定，当然不能超过100 ！

2），保存后，双击即可运行。

没结束时要退出，可同时按ALT和回车键回到小窗口，再关闭。 （以后，再完善程序，使得在游戏中按下键关闭。）

二， 怎样赢？

小赛车虽然可以上下左右移动，但只是象征性的，本游戏只是小习作，不具有三维立体仿真功能，只是二维图形游戏。所以，当小赛车移动时，游戏画面不会跟着延伸。游戏的通关要求仅仅是：不撞车，行车里程达到10000公里。所以，当你移动小赛车时（尤其是向前（也就是向上）），你要高度集中，很可能马上就有过路车撞上你了！ 哈哈。。

三， 界面语言

由于显示中文教烦琐，要好多文件配合才能运行中文字库，所以选择简洁的英语说明，只要一个程序就可以运行了。

四， 程序的遗憾

本程序只有电脑自带的小扬声器发出很小的声音，由于是DOS程序，要配上声卡上的逼真的音效，难度较大，不是每个制作程序的编译器都提供音频播放函数。目前正在想办法。。。

五，联系方式
