Well, like I said, it is a very "natural" physics model: each player has a vertical speed. GRavity adds to the speed at a constant rate, the speed is added to the vertical position at a constant rate, a flap subtracts a certain amount from the vertical speed. > > > "Perfected" is such a funny word...there really isn't an objective > > measurement for it. > > True, but I have to agree with Glenn here.

Actually, I think mucking w/ the physics is generally pretty easy. Just make sure by the end of the VBLANK, the vertical positions for P0 and P1 have been decided... Part of the problem might be early on I had to go to a 2 line kernal, which reduces the smoothness. Though maybe I could calculate position as if it were a 1 line kernal, and then just divide by 2....I mean that is the issue, akin to the "fractional speed" the list was mentioning before...for simplicity I use 'natural' values like clock counts and pixels rather than keeping track of smaller values -- KirkIsrael@xxxxxxxxxxxxx http://kisrael.com "Power corrupts.
