Currently the Advanced Contact Parameters are only available when the Contact is set to Proximity. Some of the Advanced Parameters would be just as useful on contacts set to OnEnter, and Constant. Namely the SenderType, and CollisionTag parameters.
I don't see why we shouldn't also have access to those on the other contact types. I can see why the position/velocity parameters might not be possible on the other contact types but it would be nice to have them as well if possible.
