基于纯C的小游戏，基本思想就是使用system("cls")和printf()函数不断刷新界面，捕获键盘事件，然后修改显示数组，并刷新界面。
之前有一款特别火爆的小游戏FlyBird，我们可以使用纯C语言实现，希望对大家学习C语言有所帮助。游戏界面如下：
源码可以从我的博客主页下载：

使用“#define”定义界面的宽和高：
#define HEIGHT 20
#define WIDTH 36定义界面的存储数组，ASCII码中“ ”是32，“&”是38表示小鸟，“#”是35用来画柱子，并初始化数组：

更新界面中的柱子，使用rand随机生成柱子位置，并更新数组中的35（#）
void newinterface(void)
{if (bird_desk[0][1] == 35 && num==0)//当矩阵第二列为黑色方块时，计算出下一次黑柱子上半部分的位置{black = 5 + rand() % 5;num = 2;//黑柱子是两列#组成，第二列与第一列位置一样，用num保证两列位置一致}for (int i = 0; i < HEIGHT; i++){for (int j = 0; j < WIDTH - 1; j++){bird_desk[i][j] = bird_desk[i][j + 1];}if (bird_desk[0][0] == 35 && (i < black || i>(black + 5)))//此时上面的第二列变成了第一列，更新下一个黑柱子，有了黑柱子上半部分位置+5即是下半部分的起始位置{bird_desk[i][WIDTH-1] = 35;}else{bird_desk[i][WIDTH-1] = 32;}}if (num > 0)num--;
}响应键盘事件，并更新小鸟的位置，按一次空格或w健，小鸟位置上移3格，由于上端为数组的小数端，因此对小鸟位置参数减3。不按小鸟位置降落1格，对小鸟参数加1。
/*更新小鸟位置*/
void birdmove(void)
{for (int a = 0; a < 3; a++){if (a == 2 && p > 0)//减缓鸟的速度，使按键上跳速度是下落的4倍{p = p + 1;}if (_kbhit()){if (_getch() == ' ' || _getch() == 'w' || _getch() == 'W'){p = p - 3;}}}
}当小鸟穿越柱子后进行积分，当小鸟撞到柱子或者跌到地面，小鸟死亡显示Game Over：
/*计分*/
void scoring(void)
{if (p > 20 || bird_desk[p][0] == 35){system("cls");printf("\n\n");printf(" Game Over!\n\n");printf(" Thank you!\n\n");printf(" Your score is：%d\n\n\n", score);p= HEIGHT/2 ;score=0;system("pause");}if (bird_desk[0][0] == 35 && bird_desk[0][1] == 32 )score++;
}重构界面，将生成的桌面数组显示在界面上
/*重画界面*/
void show_desk(void)
{system("cls");printf(" FlyBird Game Author：Dog语言\n");printf(" 按\"w\"或\"空格键\"使小鸟飞起来，顺利穿越更多柱子\n");for (int i = 0; i < HEIGHT; i++){printf(" ");for (int j = 0; j < WIDTH; j++){if (i == p && j == 0 && bird_desk[p][0] != 35)printf("%c", 38);elseprintf("%c", bird_desk[i][j]);}printf("\n");}printf(" Score is：%d \n", score);
}主循环循环调用上述函数，小鸟移动速度是柱子移动速度的4倍，因此循环一圈中嵌套4次小鸟移动函数。
int main(void)
{for(;;){newinterface();scoring();//过一个柱子计一次分，所以和柱子更新速度一致for (int i = 0; i < 4; i++)//小鸟的速度是柱子的4倍{birdmove();show_desk();Sleep(50);}}return 0;
