贪吃蛇的代码实现涉及多个编程语言和平台，以下是不同语言的简单示例及实现要点：
一、Python实现（使用Pygame库）
```python
import pygame
import random
定义颜色
white = (255, 255, 255)
yellow = (255, 255, 102)
black = (0, 0, 0)
red = (213, 50, 80)
green = (0, 255, 0)
初始化
pygame.init()
screen = pygame.display.set_mode((640, 480))
clock = pygame.time.Clock()
snake_block = 10
snake_speed = 15
蛇的初始位置和长度
snake_x =
snake_y =
snake_length = 1
fruit_x = random.randrange(0, 640, 10)
fruit_y = random.randrange(0, 480, 10)
游戏主循环
running = True
while running:
for event in pygame.event.get():
if event.type == pygame.QUIT:
running = False
elif event.type == pygame.KEYDOWN:
if event.key == pygame.K_LEFT:
snake_speed = -snake_block
snake_speed = 0
elif event.key == pygame.K_RIGHT:
snake_speed = snake_block
snake_speed = 0
elif event.key == pygame.K_UP:
snake_speed = 0
snake_speed = -snake_block
elif event.key == pygame.K_DOWN:
snake_speed = 0
snake_speed = snake_block
更新蛇的位置
snake_x += snake_speed
snake_y += snake_speed
snake_body.insert(0, (snake_x, snake_y))
检查碰撞
if snake_x == fruit_x and snake_y == fruit_y:
score += 1
fruit_x = random.randrange(0, 640, 10)
fruit_y = random.randrange(0, 480, 10)
for i in range(1, snake_length):
if snake_body[i] == (snake_x, snake_y):
running = False
if snake_x < 0 or snake_x >= 640 or snake_y < 0 or snake_y >= 480:
running = False
绘制
screen.fill(black)
for x, y in snake_body:
pygame.draw.rect(screen, green, (x, y, snake_block, snake_block))
pygame.draw.rect(screen, red, (fruit_x, fruit_y, snake_block, snake_block))
pygame.display.flip()
clock.tick(10)
pygame.quit()
```
二、C语言实现（控制台版）
```c
include include include include define WIDTH 20 define HEIGHT 20 define BLOCK_SIZE 20 typedef struct { int x, y; } Point; typedef enum { STOP, LEFT, RIGHT, UP, DOWN } Direction; Point snake; int snake_length = 1; Point fruit; int score = 0; Direction dir = STOP; void setup() { dir = STOP; snake.x = WIDTH / 2; snake.y = HEIGHT / 2; fruit.x = rand() % WIDTH; fruit.y = rand() % HEIGHT; } void draw() { system("cls"); for (int i = 0; i < WIDTH + 2; i++) printf(""); printf("\n"); for (int i = 0; i < HEIGHT; i++) { for (int j = 0; j < WIDTH; j++) { if (j == 0) printf(""); if (i == fruit.y && j == fruit.x) printf("O"); else if (i == snake.y && j == snake.x) printf("o"); else if (j >= 0 && j < WIDTH && i >= 0 && i < HEIGHT && snake[i].x == j && snake[i].y == i) printf("X"); else printf(" "); } printf("\n"); } } void update() { switch (dir) { case LEFT:
