2d game physics?

Question

Can anyone point me to a library for 2D game physics, etc for programming gravity, jumping actions, etc for a 2d platform/sidescrolling game ? Or could you suggest some algo

Answer 1

You could look at the Havok engine. I believe they released a free version for non-commerical use. There is a constraint kit for it that will allow you to constrain the physics to 2 planes, in your case, x and y.

Answer 2

I've used Box2D in personal projects. It is a 2D physic simulation API. But, it might be overkill if what you want is more a game/graphic API.

Answer 3

Your best bet is most likely Box2D. It does 2D physics, has tons of options, and is very easy to integrate into an existing project. It does CCD by default for fixed bodies, but any rigid body can be selectively included in the CCD calculation.

Answer 4

It sounds like Chipmunk might meet your needs.

Answer 5

This guy has done a lot of work with Javascript games:

Answer 6

You can do 2d physics with opende as well
