I'm trying to make a game that uses Farseer physics engine as its main collision detection engine. I have a 2d circle body object that has a matching fixture (I used the CreatCircle method. I did not create the fixtures and bodies separate). When IsSensor is set to false, objects collide with this circle and bounce off. My goal was to have events triggered when other physics enabled bodies move through this field and just use the engine to detect the collisions (or rather intersections) so I set it to IsSensor = true, and now all the other bodies pass right through but I do not get collision events. The be specific, sometimes I do get events but not continuously as I would expect. My intention was to have this collision code fired each time the world re evaluated collisions.
Does anyone know a way to do this. My googling has led me nowhere and I'll be fudging with the limited farseer documentation I can find this weekend to try and get this right.
Thanks ahead of time.
