Bouncey returns - more canvas physics

This is a slightly upgraded version of the physics demo I showed in my last post.

It is still…

“a buggy, rudimentary, just-for-fun javascript physics simulator."

This version has:

• pre-defined initial states
• gravity
• friction

It still has the “clinging” bug. I know how to fix it, but didn’t deem it important enough to spend time on it. :)

The code is well commented, so feel free to hack on it.

Click on one of the initial states to begin the simulation.

Choose an initial state: Random POOL HEAD_ON_COLLISION

Pause

  velocity sum: NONE
x velocity sum: NONE
y velocity sum: NONE

(The POOL initial state reproduces the clinging bug.)
