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:<\/p>\n

\"F<\/p>\n

I also implemented collisions with the planets: when you hit a planet, the large planet disappears.<\/p>\n

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<\/a> 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<\/a>\u00a0function.<\/p>\n

I think it’s time to go to sleep for a bit.<\/p>\n
