### Python 实现的贪吃蛇游戏完整源码示例 以下是基于 Pygame 库开发的一个简单的贪吃蛇游戏完整的 Python 源代码： ```python import pygame import time import random pygame.init() white = (255, 255, 255) yellow = (255, 255, 102) black = (0, 0, 0) red = (213, 50, 80) green = (0, 255, 0) blue = (50, 153, 213) dis_width = 800 dis_height = 600 dis = pygame.display.set_mode((dis_width, dis_height)) pygame.display.set_caption('Snake Game by Edureka') clock = pygame.time.Clock() snake_block = 10 snake_speed = 15 font_style = pygame.font.SysFont(None, 50) 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]) def message(msg, color): mesg = font_style.render(msg, True, color) dis.blit(mesg, [dis_width / 6, dis_height / 3]) def gameLoop(): game_over = False game_close = False x1 = dis_width / 2 y1 = dis_height / 2 x1_change = 0 y1_change = 0 snake_List = [] Length_of_snake = 1 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("You Lost! Press Q-Quit or C-Play Again", red) 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 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] for x in snake_List[:-1]: if x == snake_Head: game_close = True our_snake(snake_block, snake_List) pygame.display.update() 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() gameLoop() ``` 这段代码展示了如何创建一个基本版本的贪吃蛇游戏，其中包含了初始化设置、事件处理逻辑以及绘制函数等内容[^1]。 #### 初始化部分 定义了颜色常量，并设置了窗口尺寸和其他参数。还设定了蛇的身体大小 `snake_block` 和移动速度 `snake_speed`。 #### 函数定义 - `our_snake`: 绘制当前状态下的整条蛇。 - `message`: 显示消息给玩家看，在这里主要用于显示失败后的提示信息。 #### 主循环 `gameLoop()` 负责管理整个游戏流程，包括检测键盘输入来改变方向、判断碰撞条件（撞墙或自咬）、更新食物位置并增加长度等核心功能。 通过上述代码可以构建出一个简易版但具备完整功能性的贪吃蛇小游戏应用[^2]。
