Are you saying at the other end, it may be, in effect, "instant"? It was also nice to hear from Paul that a lot of games don't use the full range, I thought it might be some kind of "requirement" Speaking of MondoPong, is the paddle reading why the gameplay is confined to a smaller part of the screen? > > I guess this weekend I can try whipping up some sample code.

Oh, not the answer for this, but if I do make a paddle game, it will hopefully be close enough in behavior that I can use it for testing...it should be closer to the real thing than using the mouse, after all... -- KirkIsrael@xxxxxxxxxxxxx http://kisrael.com "Give me a plant with a demonstrable sense of irony, then I'll be all over botany." --2000-8-19 ---------------------------------------------------------------------------------------------- Archives (includes files) at http://www.biglist.com/lists/stella/archives/ Unsub & more at http://www.biglist.com/lists/stella/
