This is the Timer script that I used for my "Air Hockey" game. I've cleaned it up so you can use it if you want!
An interactive 2D physics simulation by Sirfryingpan, running in the browser on Physion. Nothing to install. Open it to run the simulation, change any object's properties, or copy it into a scene of your own.
