(I doubt there is an add-on for this already, but if so, give me the link please.)
I was thinking about space when I thought about how gravity is what keeps things on planets. What if you could just go to a bricks event and say "SetGravity>300>Everything"? And like, "everything" could be changed from "people", or to "bricks", depending on what you want it to pull in. The higher the number, the stronger the gravity (up to 999). And having it where if you put in a negative number then is pushes you away (down to -999). :3
