好的，下面是一个简单的Python贪吃蛇游戏代码示例： ```python import pygame import random # 初始化 pygame.init() # 定义颜色 white = (255, 255, 255) black = (0, 0, 0) red = (255, 0, 0) # 设置窗口和格子的大小 window_width = 400 window_height = 300 grid_size = 10 # 创建窗口 window = pygame.display.set_mode((window_width, window_height)) pygame.display.set_caption('贪吃蛇') # 定义字体 font = pygame.font.SysFont(None, 25) # 更新得分 def draw_score(score): score_text = font.render("得分：" + str(score), True, black) window.blit(score_text, [0, 0]) # 绘制贪吃蛇 def draw_snake(snake_block, snake_list): for x in snake_list: pygame.draw.rect(window, black, [x[0], x[1], snake_block, snake_block]) # 主函数 def main(): game_over = False game_close = False # 贪吃蛇的位置和速度 x1 = window_width / 2 y1 = window_height / 2 x1_change = 0 y1_change = 0 # 食物的位置 foodx = round(random.randrange(0, window_width - grid_size) / 10.0) * 10.0 foody = round(random.randrange(0, window_height - grid_size) / 10.0) * 10.0 # 贪吃蛇的长度和速度 snake_block = 10 snake_speed = 15 # 贪吃蛇的身体 snake_list = [] length_of_snake = 1 # 游戏循环 while not game_over: # 游戏结束 while game_close: window.fill(white) game_over_text = font.render("游戏结束，按Q退出或R重新开始", True, red) window.blit(game_over_text, [window_width / 6, window_height / 3]) draw_score(length_of_snake - 1) pygame.display.update() # 重新开始或退出 for event in pygame.event.get(): if event.type == pygame.KEYDOWN: if event.key == pygame.K_q: game_over = True game_close = False if event.key == pygame.K_r: main() # 监听事件 for event in pygame.event.get(): if event.type == pygame.QUIT: game_over = True if event.type == pygame.KEYDOWN: if event.key == pygame.K_LEFT: x1_change = -snake_block y1_change = 0 elif event.key == pygame.K_RIGHT: x1_change = snake_block y1_change = 0 elif event.key == pygame.K_UP: y1_change = -snake_block x1_change = 0 elif event.key == pygame.K_DOWN: y1_change = snake_block x1_change = 0 # 边界判断 if x1 >= window_width or x1 < 0 or y1 >= window_height or y1 < 0: game_close = True # 移动贪吃蛇 x1 += x1_change y1 += y1_change window.fill(white) # 绘制食物 pygame.draw.rect(window, red, [foodx, foody, snake_block, snake_block]) # 绘制贪吃蛇 snake_head = [] snake_head.append(x1) snake_head.append(y1) snake_list.append(snake_head) if len(snake_list) > length_of_snake: del snake_list[0] for x in snake_list[:-1]: if x == snake_head: game_close = True draw_snake(snake_block, snake_list) draw_score(length_of_snake - 1) pygame.display.update() # 吃到食物 if x1 == foodx and y1 == foody: foodx = round(random.randrange(0, window_width - grid_size) / 10.0) * 10.0 foody = round(random.randrange(0, window_height - grid_size) / 10.0) * 10.0 length_of_snake += 1 # 控制游戏速度 clock = pygame.time.Clock() clock.tick(snake_speed) # 退出游戏 pygame.quit() quit() # 启动游戏 main() ``` 以上是一个简单的贪吃蛇游戏代码示例，你可以在Python环境中运行它，进行游戏体验。
