TO LOAD THIS CART in Pico-8, type:
Use the ARROW KEYS to navigate and the (O) key to flip back and forth between 2D stars and 3D stars.
Sphere Stars as I call them has always been something to elude me. While I spent literal months on and off years ago back in QBasic trying to reproduce the "bowl" effect, I was never entirely successful.
Thanks to @freds72 he showed me it is indeed possible to reproduce. And maybe that was the push I needed to try one more time using a method I knew would benefit me later.
What method is that you ask ?
I have remapped every single pixel on the screen to a circular bowl. So when you plot on the screen instead of a rectangle you are actually drawing in a bowl and you get that nice curved effect when you navigate around the 2D star array.
I first saw this animation on a NES cart called, "Star Voyager." I remember renting it at the time and being utterly fascinated with how the stars moved in it, even being late in returning it even though I had no idea how to play the game. :)
And now I have mastered it. So what's next ? Well since I finally have star movement code the way I want it I can start working on a good space-shooter game. I may even incorporate my HYPERSPACE effect as part of the game. :)
