贪吃蛇简单代码python

以下是一个简单的贪吃蛇游戏的 Python 代码示例：

import pygame
import time
import random
 
pygame.init()
 
white = (255, 255, 255)
black = (0, 0, 0)
red = (213, 50, 80)
green = (0, 255, 0)
blue = (50, 153, 213)
 
width = 600
height = 400
 
dis = pygame.display.set_mode((width, height))
pygame.display.set_caption('Snake Game by edureka.co')
 
clock = pygame.time.Clock()
 
snake_block = 10
snake_speed = 30
 
font_style = pygame.font.SysFont(None, 30)
 
 
def message(msg, color):
    mesg = font_style.render(msg, True, color)
    dis.blit(mesg, [width / 6, height / 3])
 
 
def gameLoop():  # creating a function
    game_over = False
    game_close = False
 
    x1 = width / 2
    y1 = height / 2
 
    x1_change = 0
    y1_change = 0
 
    foodx = round(random.randrange(0, width - snake_block) / 10.0) * 10.0
    foody = round(random.randrange(0, 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_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 >= width or x1 < 0 or y1 >= 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])
        pygame.draw.rect(dis, black, [x1, y1, snake_block, snake_block])
        pygame.display.update()
 
        if x1 == foodx and y1 == foody:
            print("Yummy!!")
        clock.tick(snake_speed)
 
    pygame.quit()
    quit()
 
 
gameLoop()

这个代码使用了 Pygame 库来实现游戏的图形界面和游戏逻辑。在这个代码中，你可以控制一个小蛇在屏幕上移动，并吃掉随机生成的食物，使得小蛇的身体变长。当小蛇撞到边界或者撞到自己的身体时，游戏结束。
