Howdy,
I'm a newbie game programmer. I was wondering if I could
have some help with sprite collisions...
basically x and y are positions for sprite one
and naturally x2 and y2 are positions for sprite 2
could somebody help me with the whole bounding box thing
like just a little code or append to this code.
I just want it so when the two sprites bump into each=20
other they stop.  The sprites I have are 64X64...pretty
standard. I KNOW this is really simple I just don't know
where to start.....
any help would be GREATLY appreciated!!!!!
THANKS!!!!!!!!!!
// Control for Player 1
  if(key[KEY_LEFT]&& x!=3D0)
   x++;
  if(key[KEY_RIGHT] && x!=3D -575)
   x--;
  if(key[KEY_UP] && y!=3D0)
   y++;
  if(key[KEY_DOWN] && y!=3D-330)
   y--;
  =20

// Control for Player 2
  if(key[KEY_A] && x2!=3D 0)
   x2++;
  if(key[KEY_D] && x2 !=3D -575)
   x2--;
  if(key[KEY_W] && y2 !=3D 0)
   y2++;
  if(key[KEY_S] && y2 !=3D -330)
   y2--;
THANKS AGAIN!!!
Gosack
