这篇文章主要为大家详细介绍了C语言实现——《进化版贪吃蛇项目》,也就是在我们上一个发布的文章项目分享的基础上,实现贪吃蛇的自动举措,你可以按键也可以不按键,让蛇本身找食物!还是挺好玩的,一起来看看吧!
文中示例代码介绍的非常详细,具有一定的参考价值,感兴趣的小伙伴们可以参考一下!
项目实现要求:
1.学过C语言
2.熟悉C语言数组
3.熟悉结构体
4.按键交互 步伐:1.按键交互 2.鼠标交互
5.创建图形窗口
6.基本绘图
但是这些在我们项目源码里面都会有注释,大家到时间学习的时间千万不要忽略注释,注释可以更好地帮你理解代码,尤其是C语言初学者。
本项目编译情况:VS2019/VS2013;
插件:图形库插件easyX;
效果图演示:
