2021新年快乐呀，两天都没出去玩终于写完这个小游戏。

之前上一篇博文说过要写跑酷来着，但因为我实在太菜了就中途放弃了，换成了公路障碍赛车。。。

界面如图，感觉是个比较劣质的游戏。。。但是它还是一个有碰撞判断，有bgm，有加速功能的比较健全的小游戏的（小声bbbbbb…) 当然也会有bug。。。不管怎么说，这是我学C++三个月以来第一次自己写完四百行代码，还是值得记录一下下的。

老师布置作业时，也在网上搜了很多教程，但。。emmmm一言难尽，首先是贪吃蛇和碰撞小球的比较多，跑酷和赛车的easyx案例是真的少，要么就是太难懂（因为我太菜了），会用到我们还没学过的复杂的函数和库还有链表什么的 （我只学到指针呜呜呜，这些是下学期的内容了）。

如果你跟我一样是个绝对的新手，那这个代码就很友好了~~

一般我拿到一个别人写的好长的代码我就不想看了。。所以贴心的 我准备了超级完备的压缩包！！素材源码一应俱全！！
附上链接：https://download.csdn.net/download/m0_51357657/14014675
（免费的资源它不可吗？）

而且！！PPT 中有非常非常详细的教程！！一看就会！！（因为我本人水平就很低。。。）

不想下载压缩包的。。只能看看这个了。。

//代码报错的伙伴考虑一下项目属性里要设置成多字符集哦！
//PS：这里没给素材，压缩包里有素材，也可以用自己的素材哈

如果有错的地方还请谅解啊。。。
