So this is a general question, in my Unity project I have NPC units that move around a map using Aron's A* package. Each Object on the top level has a Character Controller, Rigidbody, and Box Collider, along with various Playmaker scripts. Right now, I'm using that box collider to trigger various behaviors for the game. However, when the NPCs are navigating around they will occasionally clash with each other where they basically stand in each others way and no one moves. What I want to happen is for my units to walk through each other entirely as if they aren't even there. Does anyone have any ideas how to basically have them have colliders and rigidbodies for the appropriate physics for game systems, but to ignore it for each other so they can path through each other?
