win32编程之俄罗斯方块

因为把目标定在了游戏上，最近在学习win32编程

经过一段时间的学习，开始进行编程实现俄罗斯方块，记录一下其中遇到的一些问题

一开始是看网上的教程学习的，但是做完一部分之后发现   会有闪屏的情况   所以又去网上搜索了一下发现要用到双缓冲。

注意：这段开始正确性有待考证！

我一开始的时候是把

drawTeris();

drawBackGround();

drawBlocked();

都放在了WM_PAINT事件里

而且里面都用了双缓冲来绘制，结果导致后面闪屏更加频繁，后来把所有的绘制动作都交由一个缓冲区来处理，然后删掉其他函数中的双缓冲相关代码并加入drawBackGround中，这样在WM_PAINT事件中只需要调用一次drawBackground就行了  而且也没发现有闪屏了。

另外还发现一个比较奇葩的问题：

一个用了BOOL类型的变量后面把他当作bool类型进行memcpy的时候会出问题

贴上在网上找到的资料：

windows为了兼容问题定义的基础变量。

typedef unsigned long        DWORD;

typedef int                  BOOL;

typedef unsigned char        BYTE;

typedef unsigned short       WORD;

typedef float                FLOAT;

typedef FLOAT                *PFLOAT;

typedef BOOL near            *PBOOL;

typedef BOOL far             *LPBOOL;

typedef BYTE near            *PBYTE;

typedef BYTE far             *LPBYTE;

typedef int near             *PINT;

typedef int far              *LPINT;

根据上面这段可以发现其实BOOL是个int类型的
