I have a problem making this concept to work.
I spent 3 day thinking and testing different gravity methods but I think that my knowledge of maths and construct is not enough to make this to work.
So... my player is on a planet and rotates in his gravity. He cant move but can use jetpack(jump). When he jumps, he can go to another nearby planet and starts rotating inn his gravity.
Hope the concept is clear.
Thank you all for helping me :)
