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,randomfrom 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()elif event.type == KEYDOWN:if event.key == K_RIGHT:                    changeDirection = 'right'if event.key == K_LEFT:                    changeDirection = 'left'if event.key == K_UP:                    changeDirection = 'up'if event.key == K_DOWN:                    changeDirection = 'down'#对应键盘Esc键if event.key == K_ESCAPE:                    pygame.event.post(pygame.event.Event(QUIT))#确定方向if changeDirection == 'left' and not direction == 'right':            direction = changeDirectionif changeDirection == 'right' and not direction == 'left':            direction = changeDirectionif changeDirection == 'up' and not direction == 'down':            direction = changeDirectionif changeDirection == 'down' and not direction == 'up':            direction = changeDirection  #根据方向移动蛇头的坐标if direction == 'right':            snakePosition[0] += 20if direction == 'left':            snakePosition[0] -= 20if direction == 'up':            snakePosition[1] -= 20if direction == 'down':            snakePosition[1] += 20 #增加蛇的长度        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 = 0else:            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.draw.rect(playSurface,redColor,Rect(targetPosition[0],targetPosition[1],20,20))         pygame.display.flip() if snakePosition[0]> 620 or snakePosition[0] < 0:            gameOver()elif snakePosition[1] > 460 or snakePosition[1] < 0:            gameOver()#修改速度        fpsColck.tick(10) if __name__ == '__main__':    main()
