Python贪吃蛇游戏代码示例 - 使用Pygame库

下面是一个简单的贪吃蛇Python代码示例：\n\npython\nimport pygame\nimport time\nimport random\n\npygame.init()\n\nwhite = (255, 255, 255)\nblack = (0, 0, 0)\nred = (255, 0, 0)\ngreen = (0, 255, 0)\nblue = (0, 0, 255)\n\ndisplay_width = 800\ndisplay_height = 600\n\ngameDisplay = pygame.display.set_mode((display_width, display_height))\npygame.display.set_caption('贪吃蛇')\n\nclock = pygame.time.Clock()\nsnake_block = 10\nsnake_speed = 30\n\nfont_style = pygame.font.SysFont(None, 50)\nscore_font = pygame.font.SysFont(None, 35)\n\n\ndef our_snake(snake_block, snake_list):\n for x in snake_list:\n pygame.draw.rect(gameDisplay, green, [x[0], x[1], snake_block, snake_block])\n\n\ndef message(msg, color):\n mesg = font_style.render(msg, True, color)\n gameDisplay.blit(mesg, [display_width / 6, display_height / 3])\n\n\ndef gameLoop():\n game_over = False\n game_close = False\n\n x1 = display_width / 2\n y1 = display_height / 2\n\n x1_change = 0\n y1_change = 0\n\n snake_List = []\n Length_of_snake = 1\n\n foodx = round(random.randrange(0, display_width - snake_block) / 10.0) * 10.0\n foody = round(random.randrange(0, display_height - snake_block) / 10.0) * 10.0\n\n while not game_over:\n\n while game_close == True:\n gameDisplay.fill(blue)\n message("你输了！按 Q-退出，C-重新开始", red)\n pygame.display.update()\n\n for event in pygame.event.get():\n if event.type == pygame.KEYDOWN:\n if event.key == pygame.K_q:\n game_over = True\n game_close = False\n if event.key == pygame.K_c:\n gameLoop()\n\n for event in pygame.event.get():\n if event.type == pygame.QUIT:\n game_over = True\n if event.type == pygame.KEYDOWN:\n if event.key == pygame.K_LEFT:\n x1_change = -snake_block\n y1_change = 0\n elif event.key == pygame.K_RIGHT:\n x1_change = snake_block\n y1_change = 0\n elif event.key == pygame.K_UP:\n y1_change = -snake_block\n x1_change = 0\n elif event.key == pygame.K_DOWN:\n y1_change = snake_block\n x1_change = 0\n\n if x1 >= display_width or x1 < 0 or y1 >= display_height or y1 < 0:\n game_close = True\n x1 += x1_change\n y1 += y1_change\n gameDisplay.fill(black)\n pygame.draw.rect(gameDisplay, red, [foodx, foody, snake_block, snake_block])\n snake_Head = []\n snake_Head.append(x1)\n snake_Head.append(y1)\n snake_List.append(snake_Head)\n if len(snake_List) > Length_of_snake:\n del snake_List[0]\n\n for x in snake_List[:-1]:\n if x == snake_Head:\n game_close = True\n\n our_snake(snake_block, snake_List)\n pygame.display.update()\n\n if x1 == foodx and y1 == foody:\n foodx = round(random.randrange(0, display_width - snake_block) / 10.0) * 10.0\n foody = round(random.randrange(0, display_height - snake_block) / 10.0) * 10.0\n Length_of_snake += 1\n\n clock.tick(snake_speed)\n\n pygame.quit()\n quit()\n\n\ngameLoop()\n\n\n这是一个基本的贪吃蛇游戏，使用pygame库实现。你可以运行该代码，通过上下左右方向键控制贪吃蛇的移动，吃到食物会增加长度，碰到边界或自己身体会结束游戏。
