Hi i'm now using farseer 3.2 and i'm getting an error from class Islands.cs from the line: Debug.Assert(ContactCount < _contactCapacity);
Can anyone tell me what this means? What might be causing it? is this common?
For refference, this error is thrown when i create bullet objects of class Bullet like this:
Vector2 bulletPos = Vector2.Zero;
bulletPos += new Vector2(300, 200);
float rotation = circleBody.Rotation;
Vector2 Pos = ConvertUnits.ToSimUnits(bulletPos);
Bullet b = new Bullet(bulletTex,
new Vector2(20, 0),
and class Bullet looks like this:
public Body bulletBody;
public Fixture bulletFixture;
public Bullet(Texture2D bulletTex, Vector2 position, float rotation, Vector2 velocity, Game1 parentGame)
this.bulletTex = bulletTex;
this.bulletOrigin = new Vector2(bulletTex.Width / 2, bulletTex.Height / 2);
this.velocity = velocity;
bulletFixture = FixtureFactory.CreateRectangle(parentGame.world, bulletTex.Width, bulletTex.Height, 1);
bulletFixture.Friction = 0;
bulletFixture.Restitution = 0;
bulletBody = bulletFixture.Body;
bulletBody.BodyType = BodyType.Dynamic;
bulletBody.IsBullet = true;
bulletBody.Position = position;
bulletBody.Rotation = rotation;
bulletBody.LinearVelocity = velocity;
public void Draw(GameTime gameTime, SpriteBatch spriteBatch)
Vector2 position = ConvertUnits.ToDisplayUnits(bulletBody.Position);
I've not had this problem until now and i've happily been creating working objects in lists from my tile engine.

I'd appreciate it if someone could even just tell me what ContactCount and _contactCapacity are?
Ok then, i finally managed to work out this problem. I believe the contact problem was occuring because the object was undergoing too many collisions. The problem was i'd forgotten to use ConvertUnits on the width and height of the fixture.
