pygame贪吃蛇游戏制作

以下是使用Python和Pygame制作的经典贪吃蛇游戏的示例代码：

import pygame
import random

# 初始化游戏
pygame.init()

# 定义颜色
BLACK = (0, 0, 0)
WHITE = (255, 255, 255)
GREEN = (0, 255, 0)
RED = (255, 0, 0)

# 设置屏幕尺寸
screen_width = 800
screen_height = 600
screen = pygame.display.set_mode((screen_width, screen_height))
pygame.display.set_caption("贪吃蛇游戏")

# 定义蛇的初始位置和大小
snake_block_size = 20
snake_speed = 15
font_style = pygame.font.SysFont(None, 50)
score_font = pygame.font.SysFont(None, 35)


def our_snake(snake_block_size, snake_list):
    for x in snake_list:
        pygame.draw.rect(screen, GREEN, [x[0], x[1], snake_block_size, snake_block_size])


def message(msg, color):
    mesg = font_style.render(msg, True, color)
    screen.blit(mesg, [screen_width / 6, screen_height / 3])


def game_loop():
    game_over = False
    game_close = False

    # 初始化蛇的位置和移动方向
    x1 = screen_width / 2
    y1 = screen_height / 2
    x1_change = 0
    y1_change = 0

    # 初始化蛇的身体
    snake_List = []
    Length_of_snake = 1

    # 初始化食物的位置
    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:
            screen.fill(BLACK)
            message("游戏结束！按Q退出或C重新开始", 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:
                        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

                    x1_change = 0
                elif event.key == pygame.K_DOWN:
                    y1_change = snake_block_size
                    x1_change = 0

        # 判断蛇是否撞墙
        if x1 >= screen_width or x1 < 0 or y1 >= screen_height or y1 < 0:
            game_close = True
        x1 += x1_change
        y1 += y1_change
        screen.fill(BLACK)
        pygame.draw.rect(screen, RED, [foodx, foody, snake_block_size, snake_block_size])
        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)

        pygame.display.update()

        # 判断蛇是否吃到食物
        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

        # 设置游戏速度
        pygame.time.Clock().tick(snake_speed)

    pygame.quit()


game_loop()

你可以将以上代码保存为一个名为`snake_game.py`的文件，并在终端中运行该文件，即可开始游戏。
