今天，给大家介绍一个简单易懂的贪吃蛇小游戏

代码 如下

import pygame,sys,random
from pygame.locals import *
#定义颜色变量  目标方块的颜色
redColor = pygame.Color(250,0,0)
#贪吃蛇的颜色
whiteColor = pygame.Color(255,255,255)
#背景颜色
blackColor = pygame.Color(0,0,0)
 
def gameOver():
    pygame.quit()
    sys.exit()
 
 
def main():
    #初始化pygame
    pygame.init()
    #控制游戏速度
    fpsColck = pygame.time.Clock()
    #创建pygame显示层
    playSurface = pygame.display.set_mode((640,480))
    pygame.display.set_caption(‘贪吃蛇‘)
    #初始化贪吃蛇的起始坐标
    snakePosition = [100,100]
    #初始化贪吃蛇的长度
    snakeBody = [[100,100],[80,100],[60,100]]
    #初始化目标方块的坐标
    targetPosition = [300,300]
    #初始化一个目标方块的标记  目的：用来判断是否吃掉这个目标方块
    targerflag = 1
    #初始化方向
    direction = ‘right‘
    #定义一个方向变量
    changeDirection = direction
 
    while True:
        for event in pygame.event.get():
 
            if event.type == QUIT:
                pygame.quit()
                sys.exit()

            direction = changeDirection
 
 
        #根据方向移动蛇头的坐标
        if direction == ‘right‘:

        snakeBody.insert(0,list(snakePosition))
 
        #判断目标方块是否被吃掉
        if snakePosition[0] == targetPosition[0] and snakePosition[1] == targetPosition[1]:
            targerflag = 0
        else:
            snakeBody.pop()
 
        if targerflag == 0:
            x = random.randrange(1,32)
            y = random.randrange(1,24)
            targetPosition = [int(x*20),int(y*20)]
            targerflag = 1
        #绘制pygame的显示层
        playSurface.fill(blackColor)
 
        for position in snakeBody:
            pygame.draw.rect(playSurface,whiteColor,Rect(position[0],position[1],20,20))

        pygame.display.flip()
 
        if snakePosition[0]> 620 or snakePosition[0] 0:

        #修改速度
        fpsColck.tick(10)
 
if __name__ == ‘__main__‘:
    main()
