hi, in my proggy, to get a mouse click i use:

  
GetAsyncKeyState(VK_LBUTTON);

however, it repeats too fast... for a keypress i the following and it works fine.

  
  if (g_keys->keyDown [AUX_S] == TRUE) {
      g_keys->keyDown [AUX_S] = FALSE;

      ...
  }
}

but i''m not sure how to get a mouse click not to repeat so quickly. Thanks, Scott Email Website

I have this problem myself, it just hasn''t bugged me enough for me to do anything about it yet

You could do something like only checking that keystate every 10th frame or something, or every 100ms or some other time length, but that seems a bit of a kludge, because you might completely miss keys that are quickly pressed then unpressed in that time.

Buffered input with DirectInput would be better, you wouldn''t loose keystrokes that are pressed then unpressed in that time. That''s the best way I know of, but somone else probably knows the correct way of doing it.

You could try something like this :

if (mousepressed && !reg_click)
{
//Do stuff
reg_click = TRUE;
}
if (!mousepressed)
{
reg_click = FALSE;
}

At least this would stop you from holding down
the mouse button!! Don''t know about really fast clicking!!
I never tried doing this, so i don''t know if it works...
But hey...it''s worth a shot!!

Take Care!

GetAsyncKeyState will not handle just clicks by itself. As the name suggests, it gets the current state of the button or key in question. So, unless you process the WM_LBUTTONDOWN message, you'll have to do the proper checks yourself: namely, when the mouse's state changes, let the state change register only once.

hey,

XaOs, that work perfectly. It's for a map editor i'm working on and every mouse click is supposed to draw only one object (which it does now), but before as fast as i could click and release the mouse button to draw an object, i caught a good 5 states... which really sucked.

thank ya,
Scott

Xaos, unfortunately when i run the demo i get a GPF :-(

tomorrow i''ll try on another computer.

Perhaps it is because of the geforce3 ?
