Dunno really what to call it though. So, I have a sprite which is a ball with 4 lines coming out of it in all directions. I have this script to simulate gravity
( http://prntscr.com/4aho25 ). How would I make it so multiple instances can climb over each other instead of going through each other?
Basically, how do I predict where the sprite should move when he's touching another instance of the sprite?

I hope I get an answer :I

Ok, let's see…so you want the balls to bump in to each other?

Sorry, let me post the entire thing

The thing is, you could fake it if you had just balls, because that's pretty much a linear surface, consistent. But these balls have lines coming out of them. I don't know how I would deal with that. Figuring out exactly what part of the sprite is being touched? Pixel by pixel? And what would I DO with that information? How?
