Hey people, here is my code for an object for my game that is an implementation of a bomb that explodes on contact.


    class Bomb : GameObject
        public Bomb(Vector2 pos)
            Body = BodyFactory.CreateRectangle(PROTO.GetWorld(), 0.10f, 0.02f, 1);
            Shape = new PolygonShape(PolygonTools.CreateRectangle(0.05f, 0.01f), 1);
            Fixture = Body.CreateFixture(Shape);
            Body.Position = pos;
            Type = BodyType.Dynamic;
            Body.OnCollision += Body_OnCollision;

        bool Body_OnCollision(Fixture fixtureA, Fixture fixtureB, FarseerPhysics.Dynamics.Contacts.Contact contact)
            Vector2 worldPosition = Body.Position;
            Vector2 min = worldPosition - new Vector2(5, 5);
            Vector2 max = worldPosition + new Vector2(5, 5);

            AABB aabb = new AABB(ref min, ref max);
                fixture =>
                    Vector2 fv = fixture.Body.Position - worldPosition;
                    fv *= 5;
                    fixture.Body.ApplyLinearImpulse(ref fv);
                    return true;
                }, ref aabb);
            return false;


So what happens is that when my bomb hits the "floor" its fine, no lockup the impulse gets applied to the objects fine as seen here and here


However when my bomb collides with the circle, it freezes up for few seconds and i get this:


This is the code used to create my circle


Body body = BodyFactory.CreateBody(world, worldPosition);
                body.BodyType = BodyType.Dynamic;
                Random rand = new Random();
                CircleShape shape = new CircleShape(.5f, 5f);
                Fixture fixture = body.CreateFixture(shape);

Any help would be really appreciated, this is doing my head in.

It seems the lockup happens AFTER  the collision method and not during it. It seems that something holds up the thread. :/
