python写一个贪吃蛇游戏

当然可以！以下是一个简单的贪吃蛇游戏的Python代码示例： ```python import pygame import random # 初始化游戏 pygame.init() # 定义颜色 white = (255, 255, 255) black = (0, 0, 0) red = (255, 0, 0) green = (0, 255, 0) # 设置游戏窗口大小和标题 screen_width = 800 screen_height = 600 game_display = pygame.display.set_mode((screen_width, screen_height)) pygame.display.set_caption('Greedy Snake') # 设置帧率（游戏速度） clock = pygame.time.Clock() snake_speed = 15 snake_block_size = 20 snake_block_width = snake_block_size snake_block_height = snake_block_size # 设置字体 font_style = pygame.font.SysFont(None, 30) score_font = pygame.font.SysFont(None, 50) # 定义计分函数 def our_snake(snake_block_size, snake_list): for x in snake_list: pygame.draw.rect(game_display, green, [x[0], x[1], snake_block_width, snake_block_height]) # 显示得分函数 def your_score(score): value = score_font.render("Your Score: " + str(score), True, white) game_display.blit(value, [10, 10]) # 主程序函数 def game_loop(): game_over = False game_close = False # 设置初始位置 x1 = screen_width / 2 y1 = screen_height / 2 x1_change = 0 y1_change = 0 # 创建蛇身列表 snake_List = [] Length_of_snake = 1 # 随机生成食物位置 foodx = round(random.randrange(0, screen_width - snake_block_size) / 20.0) * 20.0 foody = round(random.randrange(0, screen_height - snake_block_size) / 20.0) * 20.0 while not game_over: while game_close == True: game_display.fill(black) message = font_style.render("Game Over! Press Q-Quit or C-Play Again", True, white) game_display.blit(message, [screen_width/6, screen_height/3]) your_score(Length_of_snake-1) pygame.display.update() 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_c: game_loop() 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_size y1_change = 0 elif event.key == pygame.K_RIGHT: x1_change = snake_block_size y1_change = 0 elif event.key == pygame.K_UP: y1_change = -snake_block_size x1_change = 0 elif event.key == pygame.K_DOWN: y1_change = snake_block_size x1_change = 0 # 判断是否碰到边界 if x1 >= screen_width or x1 < 0 or y1 >= screen_height or y1 < 0: game_close = True x1 += x1_change y1 += y1_change game_display.fill(black) pygame.draw.rect(game_display, red, [foodx, foody, snake_block_width, snake_block_height]) 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 our_snake(snake_block_size, snake_List) your_score(Length_of_snake - 1) pygame.display.update() if x1 == foodx and y1 == foody: foodx = round(random.randrange(0, screen_width - snake_block_size) / 20.0) * 20.0 foody = round(random.randrange(0, screen_height - snake_block_size) / 20.0) * 20.0 Length_of_snake += 1 clock.tick(snake_speed) pygame.quit() quit() # 启动游戏 game_loop() ``` 这是一个使用`pygame`库编写的简单贪吃蛇游戏代码。执行代码后，你可以通过键盘上下左右箭头控制蛇的移动，吃到食物后蛇的长度会增加。如果碰到边界或者蛇自己咬到自己，游戏就会结束。 请确保已经安装`pygame`库，并将代码保存为`.py`文件，然后运行即可开始游戏。希望对你有所帮助！
