想做个俄罗斯方块，可画矩形都出问题 看下类里的值怎么改

Question

看下画的第一个矩形就是不变，而第二个是动态的，问题是那个teris里的xy变量的值怎么不变，要怎么改才能让他显示动态的，求助啊
本想做个俄罗斯方块的
但是画个动的矩形都有问题这是头文件
#include<Windows.h> class MyBlock

public:   int x ,y;
  int stae[16];

    y = yy;
for(i =0;i<16;i++)
{
                this->stae[i] = state[i];
}

Answer 1

不要在 WM_TIMER 里画画,要把所有画图功能放到 WM_PAINT 中.
所以,楼主应该这样做:
1) 用数据结构描述当前屏幕的状态,包括各个方块的类型和位置;
2) 在 WM_PAINT 中根据数据结构把所有方块画出来;
3) 在 WM_TIMER 中只是修改数据结构,比如变动某方块的位置,然后调用 Invalidate 让系统重画屏幕.

Answer 2

这个是个规范问题，但是我在WM_PAINT里也该了数据，但是X,Y的值还是不变啊，那个矩形还是不动，麻烦再帮我看下

Answer 3

我在TIMER 和PAINT消息里跟踪调试的时候，X,Y的值就是一直不变的，WHY ?????

Answer 4

排版看得很蛋疼，特别是API编程不排版看得更蛋疼

Answer 5

to 楼主:
你在 WM_TIMER 消息里直接画了,这不合适.应该在 WM_TIMER 仅改 x y 的值,不画,而把画的工作全放在 WM_PAINT 里做.
