Just finished Build 01. I added a big planet object that exerts mass on the player using Newton’s Law of Gravitation with an arbitrary G:
I also implemented collisions with the planets: when you hit a planet, the large planet disappears.
This gave me a lot of trouble, because I haven’t tried to detect collisions in Unity before (not counting cases where a trigger object detects if another object enters it). For example, I couldn’t get the OnCollisionEnter function to register any collisions at all, regardless of whether I attempted to perform collisions between rigid bodies or sphere colliders. Eventually, I just told the player script to send messages to any objects that it hit via the OnControllerColliderHit function.

I think it’s time to go to sleep for a bit.
