为什么没办法返回‘2’这个值！大神快点出现，来帮帮我。
这是我自己还未完成的俄罗斯方块的代码，为什么judge这个函数在没办法返回“2”这个值？也就是用VS2010运行后，方块没办法左右移动了.如果在
case 'a':case 'A':case 75:
if(x>0&&judge(1,b,3,x,y)==2)x=x-20;break;
case 'w':case 'W':case 72:
if(y<410&&judge(1,b,4,x,y)==2){if(b<4)b++;else if(b==4)b=1;}break;里面把judge的函数给删掉，就能了。
用VS2010方块还能顺利的跑下来，用VC6只跑了一格，就停了。我知道在judge这个函数里面一定有猫咪，要不是里面我的格式哪里错了。
在这个语句里面
程序代码：switch(ch1)
{
//72代表上，80代表下，75代表左，77
case 'd':case 'D':case 77:
if(x<400&&judge(1,b,2,x,y)==2)x=x+20;break;
case 'a':case 'A':case 75:
if(x>0&&judge(1,b,3,x,y)==2)x=x-20;break;
case 'w':case 'W':case 72:
if(y<410&&judge(1,b,4,x,y)==2){if(b<4)b++;else if(b==4)b=1;}break;
case 's':case 'S':case 80:
if(y<410)y=y+20;break;
default:break;
}这是全部的代码，求大神教我，我看了很久了，都没找出来。
