Thanks for your reply) @ross.grams

I’ve released a new version 0.9.1
1)Add binding for b2Filter.

@ross.grams

What I mean is:

1. In the b2FixtureDef you should be able to set the filter - which should have ‘categoryBits’, ‘maskBits’, and ‘groupIndex’ fields.
2. After you create it, the b2Fixture should have:
   void SetFilterData (const b2Filter &filter)
   constb2Filter& GetFilterData () const
