Farseer ContactListener is not working

Question

I'm using Farseer in my XNA project, but I have some trouble with the ContactListener. I created a class for my ContactListener but I always get these two error messages and I don't know how to fix the problems.

The type or namespace name 'ContactListener' could not be found (are you missing a using directive or an assembly reference?)

The type or namespace name 'ContactImpulse' could not be found (are you missing a using directive or an assembly reference?)

What is wrong with my ContactListener class?

class MyContactListener: ContactListener
{
    void BeginContact(Contact contact)

    { /* handle begin event */ }


    void EndContact(Contact contact)

    { /* handle end event */ }


     void PreSolve(Contact contact, ref Manifold oldManifold)
    {
      Fixture fixtureA = contact.FixtureA;
      Fixture fixtureB = contact.FixtureB;

      if (fixtureB.CollisionCategories == Category.Cat10)
      {
        contact.Enabled = false;
      }
    }

    void PostSolve(Contact contact, ref ContactImpulse impulse)

   { /* handle post-solve event */ }

}

Answer 1

Try this:

• Open VS
• Go to the Solution Explorer window
• Search for a folder called References and right click it
• Select Add Reference...
• look for the Farseer assembly and add it

And try adding these in code:

using FarseerPhysics.Collision.Shapes;
using FarseerPhysics.Common;
using FarseerPhysics.Dynamics;
using FarseerPhysics.Dynamics.Contacts;
using FarseerPhysics.Factories;
using FarseerPhysics.TestBed.Framework;
using Microsoft.Xna.Framework;
