I am starting to see why games take so long to finish. you never reach the end but you want to start start working on something different.
Anyway, I was messing around with the Colorsquare demo/line drawing example from GroovyBee and I can't say how exactly but I ended up with something that is starting to look a little like Asteroids.
totally concept at this stage. there is no collision detection, the astroids don't blow up and split into two but I think it looks kind of neat.
If you try the ROM it should display a screen with a space ship on it.
Left side of disc rotates ship counter clockwise. Right side of disc rotates ship clockwise. Up on disc fires thruster to move ship. There is some overlap so you can rotate and move at the same time. Pressing any button will fire the gigantic torpedo. (Color Square Bloxel)
When you fire the first time the "Asteroids" will show up. This is just to randomize their speed and directions.
Source and Rom if anyone wants to play with it.
