Im triying to make a game where you have to place some balls that have gravity force, what i meant with gravity force is that when you are like 1 cm from the ball with another ball that you have to throw near it ( it doesnt matter the distance but it has to be separated from it) i need to make gravity force for some balls( when the main ball passed near the ball with gravity i need it to be attracted to the ball with gravity ) in other cases i need it to push the main ball.
