I don't really know if this is possible, but I want a type of thing like from Super Mario Galaxy, where you get pulled to the center of the planet and can run around it. I was thinking maybe I could have the player just be pulled to the middle, but then I realized I have no clue how to do that. Can anyone help, if it's even possible? Just want to make it for fun, and if it's good enough, even maybe try to make a game out of it.
