Re: [pygame] physics engine?

[Peter Gebauer <peter.gebauer@xxxxxxxxxxxxxxxxxxxxx>]

Heya!

It was really too bad that the gsoc project wasn't really finished.
It didn't need to be a full 2D physics engine like Chipmunk or Box2D,
but in it's current state it is lacking some basic, mandatory features
to be useful.

I think the collision part should be rewritten to be a part of the
PyGame standard collision library. This way you can have traditional
rect collisions, pixel based collision detection and vector based
testing all in one neet package for PyGame.

That collision library would also provide PyGame community with much
needed types for vectors, quats and the math surounding it.

As for the physics, if you can write a simple platformer it's
good enough.

Just my two cents. Also, for a good physics library check out
PyODE, it now features a 2D joint lock so you can go from 3D
to 2D without much effort.
