话说，我用c++11和opengl在mac上写过一个贪吃蛇，可以参考一下：>
主要是贪吃蛇本身的核心逻辑才70行左右（偷懒用了STL的list，不用自己实现链表）
当时装逼用英语写的注释，请不要打我！
核心逻辑大概是这样子 每次移动的时候：
2 如果蛇头吃到食物，蛇变长。
3 否则（蛇头什么都没碰到）移动蛇。
用链表存蛇身的各个位置的话，链表尾部当蛇头，那蛇变长的 *** 作很简单：把新的蛇头位置插入链表尾部。
移动蛇的 *** 作也简单：把新的蛇头位置插入链表尾部，删除链表头。
然后，剩下的事情还有两个：
1 拿到蛇身的所有位置，在对应位置画上蛇身
2 获取用户输入，改变蛇的移动方向
那。。。你需要了解的只有：
opengl怎么在指定位置画方块（圆圈）
opengl怎么处理用户输入
没了。
