I’m making a simple physics system for a game I’m working on. It only needs to handle basic sphere collisions so most options are a little heavy for what I need. I might blog a bit about the code later once it comes together a bit more, but for now here’s a little html5 demo of where it’s at ( all balls have the same mass ).
This is Haxe NME so runs as html, flash, Android, iOS and more.
