Physic Engine support

[ellisonleao]

I guess we could do something great physics for melonjs using Verlet JS [1]. I don't know if this was discussed already in the groups but i've found this lib today and it's fantastic.

(Renaming this ticket)

Just stumbled on this yesterday, seems to be nice and simple too :

Adding back here discussion on chipmunk from ticket #145 (to avoid double ticket entries)

I had a quick look at all of the demos on my iPhone 4S, and the only one that ran reasonably well was Matter-js. However, it was also the most inaccurate in terms of collision resolution. (Objects tend to "meld" together under high forces.)

I guess they all deserve some closer inspection. A good tool for comparison would be using a single renderer and swapping out the physics engine. Then record how many objects can be simulated while maintaining ~60fps.

Although it does not seem to be really maintained (last commit was 9 months ago), what about verlet ? as from my understanding it was a more simple (and I then suppose lighter) implementation that might fit with basic platformer or RPG game style

Verlet-js was incredibly slow on my iPhone 4S.

Maybe optimizing and adding new features (bounciness/restitution, mass, force) in the existing melonJS physics engine, like the hints in the links below:

now that we have way better physic/collision implementation in melonJS these two links are making much more sense with the current 2.0.0 :P
