贪食蛇MFC

第一次用MFC写程序，写的不好

变量声明：

想法很简单，用一个数组当地图，初始化为0；当走过时标记为1，食物标记为2

走过的路程用一个Array来存；蛇向前走一格蛇头就标1，蛇尾就判断（地图标志是1就清除，是2就把他刷新为蛇体）

当然还有升级，8个食物为1级

实现：

蛇走过的路程要用一个容器给装起来，我用了Array，当然用队列更好

声明：CArray RoteLine;

当然要加上头文件，#include

这样编译一下很可能会报错 fatal error C1001: INTERNAL COMPILER ERROR (compiler file 'msc1.cpp', line 1794)

就算现在不报，以后也很有可能会报，这是编译器问题，带vs2005就基本不会了

我就百度了下 发现 http://www.cnblogs.com/xinjun/archive/2010/07/16/1778637.html 写的不错

分析下我是要删除什么什么，我去找没找到

就把 工程下的 Debug下删除的只剩下 *.bsc 和那个 *.exe；

奇迹出现了，能成功编译，并没有再报过 C1001

在清理走过的轨迹时，用

InvalidateRect(CRect(Position_tial.x *30,Position_tial.y *30,Position_tial.x *30+30,Position_tial.y *30+30),true);

CRect的后两个参数不是长度，而是相对于客户区的坐标！！，搞的我纠结了好久，看地图标志没错，但视图就是不对

我是在OnStart中把游戏区开始时就画满了，这样就能看到清理函数的轨迹，才发现的，很有用！！！
