hi Is there something that i can add so that it knows or detects when a certain key is being released in glut? i.e. if up is being pressed, then accelerate, if released then decelerate. Hope it makes sense. Thanks. oh btw: i remember seeing a thread similar to this before but i cant seem to find it. plus the search function still doesnt work [edited by - xnin on January 2, 2003 10:01:10 AM]

ok then, it doesnt have to be in glut, just normal opengl.

In your WndProc function handle a message called WM_KEYDOWN.

Just look it up in Nehe''s tutorials.

glutKeyboardUpFunc() and glutSpecialUpFunc(). You might also find glutIgnoreKeyRepeat(int) useful.

Thanks for your help. I did that but now the problem is that if i release the up key, the thing moving automaticaly stops. Even if i put some loop to make it gradually slow down

i.e.while (velocity > 0)	{		velocity -=0.001;		}  

Also, i dont whant to put the glutIgnoreKeyRepeat(int) because i dont what to keep tapping on the up key to get it to move.

thanks for your help so far guys

Your loop doesn''t exit until velocity <= 0. Nothing else happens in the mean time. Instead, do something similar to :

void my_glut_idle_func(){   if( no_key_pressed )   {      if( velocity > 0 )         velocity -=0.001      else         velocity = 0;   }}
