c语言贪吃蛇devc++

在DevC++中编写C语言贪吃蛇的示例代码如下： ```c #include <stdio.h> #include <conio.h> #include <windows.h> #define WIDTH 20 #define HEIGHT 20 int score; int gameover; int x, y, fruitX, fruitY, flag; int tailX[100], tailY[100]; int nTail; void Setup() { gameover = 0; x = WIDTH / 2; y = HEIGHT / 2; fruitX = rand() % WIDTH; fruitY = rand() % HEIGHT; score = 0; } void Draw() { int i, j, k; system("cls"); for (i = 0; i < WIDTH + 2; i++) printf("#"); printf("\n"); for (i = 0; i < HEIGHT; i++) { for (j = 0; j < WIDTH; j++) { if (j == 0) printf("#"); if (i == y && j == x) printf("O"); else if (i == fruitY && j == fruitX) printf("F"); else { int printTail = 0; for (k = 0; k < nTail; k++) { if (tailX[k] == j && tailY[k] == i) { printf("o"); printTail = 1; } } if (!printTail) printf(" "); } if (j == WIDTH - 1) printf("#"); } printf("\n"); } for (i = 0; i < WIDTH + 2; i++) printf("#"); printf("\n"); printf("Score: %d\n", score); printf("Press X to quit the game"); } void Input() { if (_kbhit()) { switch (_getch()) { case 'a': flag = 1; break; case 'd': flag = 2; break; case 'w': flag = 3; break; case 's': flag = 4; break; case 'x': gameover = 1; break; } } } void Logic() { int i; int prevX = tailX[0]; int prevY = tailY[0]; int prev2X, prev2Y; tailX[0] = x; tailY[0] = y; for (i = 1; i < nTail; i++) { prev2X = tailX[i]; prev2Y = tailY[i]; tailX[i] = prevX; tailY[i] = prevY; prevX = prev2X; prevY = prev2Y; } switch (flag) { case 1: x--; break; case 2: x++; break; case 3: y--; break; case 4: y++; break; } if (x < 0 || x >= WIDTH || y < 0 || y >= HEIGHT) gameover = 1; for (i = 0; i < nTail; i++) { if (tailX[i] == x && tailY[i] == y) gameover = 1; } if (x == fruitX && y == fruitY) { score += 10; fruitX = rand() % WIDTH; fruitY = rand() % HEIGHT; nTail++; } } int main() { char c; do { Setup(); while (!gameover) { Draw(); Input(); Logic(); Sleep(10); } printf("Game over!\n"); printf("Do you want to play again? (Y/N) "); c = getchar(); } while (c == 'y' || c == 'Y'); return 0; } ```

### 贪吃蛇游戏代码实现 为了满足需求，在此提供一段简单的贪吃蛇游戏代码，该代码采用C语言编写并适合于Dev-C++环境下运行。这段程序实现了基本的游戏逻辑，包括初始化、绘制地图边界、处理键盘输入以及更新蛇的位置。 ```c #include <stdio.h> #include <conio.h> /* _getch */ #include <windows.h> #define WIDTH 20 #define HEIGHT 20 void gotoxy(int x, int y); void setcursor(bool visible); char map[HEIGHT][WIDTH]; int snake_x = 5; int snake_y = 5; enum Direction { STOP = 0, LEFT, RIGHT, UP, DOWN }; enum Direction dir; void setup() { dir = STOP; for (int i = 0; i < HEIGHT; ++i) { for (int j = 0; j < WIDTH; ++j) { if (i == 0 || i == HEIGHT - 1 || j == 0 || j == WIDTH - 1) map[i][j] = '#'; else map[i][j] = ' '; } } map[snake_y][snake_x] = '*'; // Snake head symbol } void draw() { system("cls"); for (int i = 0; i < HEIGHT; ++i) { printf("\n"); for (int j = 0; j < WIDTH; ++j) { putchar(map[i][j]); } } } void input() { if (_kbhit()) { switch (_getch()) { case 'a': dir = LEFT; break; case 'd': dir = RIGHT; break; case 'w': dir = UP; break; case 's': dir = DOWN; break; default: break; } } } void logic() { char prev_cell = map[snake_y][snake_x]; switch (dir) { case LEFT: --snake_x; break; case RIGHT: ++snake_x; break; case UP: --snake_y; break; case DOWN: ++snake_y; break; default: break; } if (map[snake_y][snake_x] != ' ') exit(0); // Collision detection with walls or itself. map[snake_y][snake_x] = '*'; if (prev_cell == ' ') map[snake_y][snake_x] = ' '; // Clear previous position. } int main() { setup(); while (true) { draw(); input(); logic(); Sleep(80); // Delay between frames to control speed of the game loop. } } ``` 上述代码展示了如何创建一个基础版本的贪吃蛇游戏[^3]。通过定义方向枚举来控制移动的方向，并利用`gotoxy()`函数调整光标的显示位置以便更好地管理终端界面布局；同时借助`_getch()`获取用户的按键指令而无需回显字符到屏幕上。
