基于Python+Pygame怎么实现经典赛车游戏

这篇文章主要介绍“基于Python+Pygame怎么实现经典赛车游戏”的相关知识，小编通过实际案例向大家展示操作过程，操作方法简单快捷，实用性强，希望这篇“基于Python+Pygame怎么实现经典赛车游戏”文章能帮助大家解决问题。

一、环境安装

1.各种素材（图片）

2.运行环境

小编使用的环境：Python3、Pycharm社区版、Pygame模块部分自带。

模块安装：pip install -i https://pypi.douban.com/simple/ pygame

二、代码展示

这款游戏代码特别多啦，小编这里就主要展示一下主程序运行的代码，全部的就找我文末拿哈~

crossing = 0
straight = 1
turn     = 2
split    = 3
deadend  = 4
null     = 5

        self.rect = self.image.get_rect()
 
        if rot != 0:
            self.image = pygame.transform.rotate(self.image, rot * 90)
 
        self.x = x
        self.y = y
 
#Realign the map
    def update(self, cam_x, cam_y):
        self.rect.topleft = self.x - cam_x, self.y - cam_y

三、效果展示

游戏玩法：M游戏开始——P重来——Q退出游戏。跟着红色箭头运行会出现奖杯。一个奖杯15

分，在规定时间拿到的奖杯越多数越高啦~

1.游戏界面

2.游戏运行中

3.15分到手
