That is the problem i lost blueprints of that game when it was still in simple form. Earliest backup of it i have is quite complicated, it will only confuse you. Anyway I will check once more later today.
Also we discontinued doing that game idea because limiting game area to just orbit of planet limits gameplay, it was just no fun at all.
There are multiple problems with gameplay on sphere, for eg: collision, shooting bullets, line trace for hitscan weapons, enemy AI (you need write it yourself from scratch), polar anomalies everywhere (about everything has potential danger for weird behavior around poles), you need to make everything physics based with constraints hooked to center. So in short a lot of battling against that polar coordinate system, without any real gain in gameplay and fun area.
Then some dillema we totally could not solve:
- small planet that fits on screen looks gorgeous, but then you have tine gameplay area, bullets start to sirculate whole planet.
- big planet means big game area, but then planet looks just like bent sheet, no point in making game areound planet anymore.
PS. and then we found this game: https://www.youtube.com/watch?v=OYMgdGuI3G4
