getMyRidingOffset doesn't take a parameter. My mob can ride two living entities, one modded, one not. For the modded one I have to adjust it to work correctly. But when the mob rides the vanilla mob, mc applies the modded entity offset to the vanilla mob, resulting in the mob being submerged within the vanilla entity's body. I have had a look at overriding the positionRider function that uses getMyRidingOffset, but that doesn't provide the vehicle entity either.
