Simulating Gravity (Or Any Attractive Force)

This tutorial shows you how to simulate an attractive force like gravity between two objects like planets.


Here are the steps I took to make this.

1. I created a sun movieclip and an earth movieclip and placed them on the stage with instance names ball1 and ball2 respectively.
2. I used FlashGuru's function that determines the distance between two movieclips and returns a distance object (with a slight modification).
3. Using the info in the distance object I determined what the velocities and accelerations of the bodies.
