Move around a sphere

Hey there,

I wanted to create a game similar to Super Stardust HD Super Stardust HD - Planet 4 - TARANIS: 22 Million points (a.k.a. Star Strike HD) - YouTube

I was wondering what the best approach was to achieve this. (player moving around a sphere killing asteroids and enemies etc.)
I read quite a lot of articles regarding Super Mario Galaxy which basically shares the same movement however all of the tutorials for such a movement require the usage of physics (Gravity) and Raycasts.
Considering the amount of bullets, asteroids and enemies in a game like Super Stardust wouldn’t that be too much if every single object would use gravity and raycasts etc ?

This is the thread that got it working for me:

Took quite a bit of work and I understood a lot less then though. Hope it works out for you :slight_smile:

Down a little bit from the initial post someone created the FauxGravity scripts and whatnot.
