Today I was able to make it so that Entities will float back to their intended position if pulled away (or hopefully in the future, pushed away by a collision.) However, working out collisions is turning out to be much more finicky than I thought. I can find out if one Bounding Sphere intersects another, but not by how much. The formula (radius_one+radius_two)-distance should give me the overlap, but instead it keeps giving me a constant! I'll tackle this in the morning and hopefully have a lot more cool things to show tomorrow, like a video!
