How to define different alarmDistance and contactDistance for different objects?

[ZA123654]

Hi,

I am using rootNode.addObject('LocalMinDistance', name="Proximity", alarmDistance="0.2", contactDistance="0.1", angleCone="0.01") for contact detection. I have two objects in my scene and I want to set different alarmDistance and contactDistance for them.
For object 1, I want to define alarmDistance="0.2" and contactDistance="0.1", but for the object 2, I need alarmDistance="1" and contactDistance="0.5". From the examples I can find, these parameters can only be defined once. Is there a way to solve it?

Dear @ZA123654

As you can notice for the ProximityIntersection API (see BaseProximityIntersection.h), the data alarmDistance and contactDistance are both only a single floating value. Therefore, these two data are global to the entire simulation.

However, in the CollisionModel, it seems that a data proximity can be defined per object as a "distance to the actual surface", i.e. some kind of offset. I never used it myself, do not hesitate to let me know if it meets your needs.

Best wishes.

@hugtalbot Thank you very much! That is what I want to implement.
