Valleskon Sep 7, 2012 at 9:18 PM Hi, im doing something whit farseer and W8 i have this code to create the circle shape, but dont move, nay missing step.   ``` _world = new FarseerPhysics.Dynamics.World( xna.Vector2.Zero); Vertices circle = PolygonTools.CreateCircle(50, 25); List _listaCirculo = new List(); _listaCirculo.Add(circle); Body circleBudy = BodyFactory.CreateCompoundPolygon(_world, _listaCirculo, 1, new xna.Vector2(10,10)); circleBudy.BodyType = BodyType.Dynamic; circleBudy.Position = new xna.Vector2(200, 200); ``` and using this code for draw the circle whit SharpDX ```foreach (Fixture fixture in circleBudy.FixtureList) { PolygonShape pol = (PolygonShape)fixture.Shape; DrawingPointF pointStart; DrawingPointF pointEnd; for (int i = 0; i < pol.Vertices.Count; i++) { pointStart.X = pol.Vertices[i].X; pointStart.Y = pol.Vertices[i].Y; if (i == (pol.Vertices.Count - 1)) { pointEnd.X = pol.Vertices[0].X; pointEnd.Y = pol.Vertices[0].Y; }else { pointEnd.X = pol.Vertices[i + 1].X; pointEnd.Y = pol.Vertices[i + 1].Y; } deviceContext.DrawLine(pointStart, pointEnd, brush); } } ``` jerrysb Sep 8, 2012 at 10:31 AM http://box2d.org/2012/03/shape-coordinates/ The vertices of a shape are in local coordinates. You should apply the body transform to them before drawing. See the DebugViewXNA for an example.
