The player's position only needs to be set once during the game, and since neither of the sprites are ever re-used, they only need to be nudged back and forth whenever one wants to move a tank. This also saves RAM, you don't have the X position stored in memory. Have you noticed that when you're cycling through the biplane games, only one player's planes are reset every time you press SELECT? -- Stella list is Administered by krishna@xxxxxxxxxxxx <Glenn Saunders> Archives (includes files) at http://www.biglist.com/lists/stella/archives/ Unsub & more at http://www.biglist.com/lists/stella/stella.html +-shameless plugs-------------------------------------------------------+ | Stella documentary at http://www.primenet.com/~krishna | | Nick's VCS links via http://www.primenet.com/~nickb/atariprg.htm | | Write the best game, win framed autographs of famous Atari alumni!! | +-----------------------------------------------------------------------+
