I've never seen a "real time" game on a tandy but I think it's possible, and for sure, for your gameplay you need to write code in assembly. I wrote a Snake game in basic and though I have way more room for speed improvement, still, it's very slow. I created my own video buffer to handle collisions but now, that I'm working on a new game, I'm looking to read directly from the screen with the input port.
One thing you could do is pre-calculate, where it's possible, before animate the ball. It depends on your gameplay. For instance, you can map your screen with coefficients depending on the gravity influences, so when you move the ball around you don't have to calculate all the interaction and you can approximate the behaviour, since your direction is affected by the coefficient of the screen zone. I don't know if I made myself clear, english's not my mother tongue Il giorno mar 3 ago 2021 alle ore 10:53 Ken Pettit <[email protected]> ha scritto: > I have been thinking about writing a game called MagBall for the M100 just > for the fun of the exercise.
