I want to have diferent reactions for diferent body collisions. For that, I've grouped them in four groups, but I don't know how to suscribe for each one of the possible combinations of collisions betwen groups.

 

How can I do it?

None can help?

I tried with 

 

public bool OnCollision(Fixture fix1, Fixture fix2, Contact contact)
        {
            if (fix1.UserData as string == "cube" && fix2.UserData as string == "grass")
            {
                contacts = true;
            }
            return true;
        }

 

but it does not work.

Can you provide a complete sample? It's hard to see what might be going wrong because your above code should work provided some other conditions are met.
