About collisions
Hi!
I have a simulation with several robots with three IR sensors (they are polygon shapes) each one around its body. I want to detect when two sensors from different robots collide, but I have a problem, because the sensors of its owner robot are overlapping (due to the structure of the robot in the real world). So, can I detect the collisions between sensors from different robots, but no the collisions between sensors of the same robot?
Here is a snapshot of my simulation:
Thanks!

About collisions
Well, I'm not sure how to keep them from detecting themselves at all, but in your collision iteration, why can't you have them check if the colliding object is itself? If self, ignore. If not self, do such-and-such. I would do this by detecting the collision then checking for the object's owner. I imagine this could be even simpler if you are using Multibody for your robot agents.

About collisions
If I compare in each collision if the sensor is in the same robot, the simulation runs very slow because there are a lot of collision, so It is impossible in this way. I have tried to use multibody agents and occurs the same...
Thanks anyway!
other ideas?
