I am trying to make a simple animation of the nucleus of an atom being bombarded by particles. I have the wall set to a mask for the nucleus, but i was wondering is there any access to the specific calculations that happen in the collision detection.
I would like to be able to count the number of colisions, but even better would be to have the particles change colour on contact. In a perfect world I could use the emphemeral property in reverse. ie map Y speed to Red, Blue & Green.
I hope some one knows how to get under the hood, or if there is an even better way to do this.
