It looks like the blocks don't all have the same densities...O.O

They all have the same density, rather, their different sizes mean they all have different masses :)

ok, so mass is based entirely on size? Makes sense.

Well actually mass is independent of size, but in that simulation I set all the masses such that they all have the same densities

Ah, so it does have different densities, but it's a variable dependent on the mass?

Each object has a specific variable for mass, which is independent of size or anything else.  Density isn't an actual variable, its just a way I describe the objects relationship between size and mass.

So you can make a 1pix*1pix object with 99 mass that you throw at a stationary block that takes up half the screen and has 1 mass and the larger object bounces around like a pinball. Fun ;D

(Is zero mass possible?  What's the max?)

Zero would cause some... problems :P Max is around 24 or so before overflow errors start happening

hmm, would overflow errors cause it to reverse direction when hit (signed #) or simply slow down a lot? (in case of 1 var for direction, 1 for magnitude)
