用PY做个贪吃蛇小游戏

当然可以！以下是一个简单的贪吃蛇小游戏的Python代码示例：

import pygame
import random

# 初始化pygame
pygame.init()

# 游戏窗口尺寸
window_width = 800
window_height = 600

# 蛇头和食物的大小
block_size = 20

# 设置游戏窗口
window = pygame.display.set_mode((window_width, window_height))
pygame.display.set_caption("贪吃蛇")

# 定义颜色
white = (255, 255, 255)
black = (0, 0, 0)
red = (255, 0, 0)

# 游戏时钟
clock = pygame.time.Clock()

# 设置蛇的初始位置和移动速度
snake_speed = 15
direction = "right"

def game_loop():
    game_over = False
    game_close = False

    # 蛇的初始位置
    x1 = window_width / 2
    y1 = window_height / 2

    # 蛇的移动速度
    x1_change = 0
    y1_change = 0

    # 定义食物初始位置
    food_x = round(random.randrange(0, window_width - block_size) / block_size) * block_size
    food_y = round(random.randrange(0, window_height - block_size) / block_size) * block_size

    while not game_over:

        while game_close:
            # 游戏结束时显示得分和重新开始选项
            window.fill(black)
            font_style = pygame.font.SysFont(None, 50)
            message = font_style.render("Game Over! Press Q-Quit or C-Play Again", True, white)
            window.blit(message, [window_width / 6, window_height / 3])
            pygame.display.update()

            for event in pygame.event.get():
                if event.type == pygame.QUIT:
                    game_over = True
                    game_close = False
                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 = -block_size
                    y1_change = 0
                elif event.key == pygame.K_RIGHT:
                    x1_change = block_size
                    y1_change = 0
                elif event.key == pygame.K_UP:
                    y1_change = -block_size
                    x1_change = 0
                elif event.key == pygame.K_DOWN:
                    y1_change = block_size
                    x1_change = 0

        # 判断蛇是否撞到边界
        if x1 >= window_width or x1 < 0 or y1 >= window_height or y1 < 0:
            game_close = True

        # 更新蛇的位置
        x1 += x1_change
        y1 += y1_change
        window.fill(black)
        pygame.draw.rect(window, white, [food_x, food_y, block_size, block_size])
        pygame.draw.rect(window, red, [x1, y1, block_size, block_size])
        pygame.display.update()

        # 判断蛇是否吃到食物
        if x1 == food_x and y1 == food_y:
            food_x = round(random.randrange(0, window_width - block_size) / block_size) * block_size
            food_y = round(random.randrange(0, window_height - block_size) / block_size) * block_size

        clock.tick(snake_speed)

    pygame.quit()


# 运行游戏
game_loop()

这只是一个简单的贪吃蛇游戏示例，你可以根据自己的需要进行修改和扩展。希望对你有帮助！
