贪吃蛇是一款经典的街机游戏，玩家操控一条蛇在屏幕上移动，不断吃食物使身体变长，同时要避免撞到墙壁或自己的身体。以下是一个使用Python和`pygame`库实现的简单贪吃蛇游戏代码： ```python import pygame import time import random # 初始化pygame pygame.init() # 定义颜色 white = (255, 255, 255) yellow = (255, 255, 102) black = (0, 0, 0) red = (213, 50, 80) green = (0, 255, 0) blue = (50, 153, 213) # 定义游戏窗口大小 dis_width = 800 dis_height = 600 # 创建游戏窗口 dis = pygame.display.set_mode((dis_width, dis_height)) pygame.display.set_caption('贪吃蛇游戏') # 定义时钟对象 clock = pygame.time.Clock() # 定义蛇的初始大小 snake_block = 10 snake_speed = 15 # 定义字体样式 font_style = pygame.font.SysFont("bahnschrift", 25) score_font = pygame.font.SysFont("comicsansms", 35) # 定义显示得分的函数 def Your_score(score): value = score_font.render("你的得分: " + str(score), True, yellow) dis.blit(value, [0, 0]) # 定义绘制蛇的函数 def our_snake(snake_block, snake_list): for x in snake_list: pygame.draw.rect(dis, black, [x[0], x[1], snake_block, snake_block]) # 定义显示消息的函数 def message(msg, color): mesg = font_style.render(msg, True, color) dis.blit(mesg, [dis_width / 6, dis_height / 3]) # 定义主游戏循环函数 def gameLoop(): game_over = False game_close = False # 蛇的初始位置 x1 = dis_width / 2 y1 = dis_height / 2 # 蛇的初始移动速度 x1_change = 0 y1_change = 0 # 蛇的身体列表 snake_List = [] Length_of_snake = 1 # 食物的随机位置 foodx = round(random.randrange(0, dis_width - snake_block) / 10.0) * 10.0 foody = round(random.randrange(0, dis_height - snake_block) / 10.0) * 10.0 while not game_over: while game_close == True: dis.fill(blue) message("你输了！按 Q-退出 或 C-重新开始", red) 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: gameLoop() 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 # 判断蛇是否撞到墙壁 if x1 >= dis_width or x1 < 0 or y1 >= dis_height or y1 < 0: game_close = True x1 += x1_change y1 += y1_change dis.fill(blue) pygame.draw.rect(dis, green, [foodx, foody, snake_block, snake_block]) 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] # 判断蛇是否撞到自己的身体 for x in snake_List[:-1]: if x == snake_Head: game_close = True our_snake(snake_block, snake_List) Your_score(Length_of_snake - 1) pygame.display.update() # 判断蛇是否吃到食物 if x1 == foodx and y1 == foody: foodx = round(random.randrange(0, dis_width - snake_block) / 10.0) * 10.0 foody = round(random.randrange(0, dis_height - snake_block) / 10.0) * 10.0 Length_of_snake += 1 clock.tick(snake_speed) pygame.quit() quit() # 调用主游戏循环函数 gameLoop() ``` 额外注意的逻辑点 1. 边界判断：在蛇移动时，要准确判断蛇是否撞到了游戏窗口的边界，避免蛇“穿墙”，否则游戏逻辑会出错。 2. 身体碰撞检测：要确保检测蛇头是否撞到了自己的身体，检测逻辑要正确，否则蛇可能会在撞到自己身体时不结束游戏。 3. 食物生成：食物生成的位置不能与蛇的身体重叠，需要在生成食物时进行检查，保证游戏的合理性。 [2025-06-06 20:22:46 | AI写代码神器 | 1352点数解答]
