Thread: A newb question about keyboard input

Yep. You're using WM_CHAR or WM_KEYDOWN messages, right? Well, that's fine, but do this instead:

Code:

bool w,s,a,d;

//stuff here

case WM_KEYDOWN:
switch(...)
{
    case 'A':
        a = true;
}
break;

case WM_KEYUP:
switch(...)
{
    case 'A':
        a = false;
}

Something like that anyways, and then in your code you do this:

Code:

int WINAPI WinMain(...)
{
    (...)
    while(...)
    {
        //your message handling stuff

        if(a)
            --position.x;
    }
}

I'm assuming he's using Windows API. Getch() is console.

Code:

Somewhere in the beginning:

#define KEY_UP 0
#define KEY_DOWN 1
#define KEY_LEFT 2
#define KEY_RIGHT 3

bool KeyDown[4] = {false};

Code:

Message handler:

case WM_KEYDOWN:
   switch(wParam)
   {
      case VK_UP:
         KeyDown[KEY_UP] = true;
         break;

      case VK_DOWN:
         KeyDown[KEY_DOWN] = true;
         break;

      case VK_LEFT:
         KeyDown[KEY_LEFT] = true;
         break;

      case VK_RIGHT:
         KeyDown[KEY_RIGHT] = true;
         break;
   }
   break;

case WM_KEYUP:
   switch(wParam)
   {
      case VK_UP:
         KeyDown[KEY_UP] = false;
         break;

      case VK_DOWN:
         KeyDown[KEY_DOWN] = false;
         break;

      case VK_LEFT:
         KeyDown[KEY_LEFT] = false;
         break;

      case VK_RIGHT:
         KeyDown[KEY_RIGHT] = false;
         break;
   }
   break;

Code:

Somewhere in your game loop

if(KeyDown[KEY_UP]) Player.Ypos--;
if(KeyDown[KEY_DOWN]) Player.Ypos++;
if(KeyDown[KEY_LEFT]) Player.Xpos--;
if(KeyDown[KEY_RIGHT]) Player.Xpos++;
