Rigidbody but no movement

Questions & Answers
1

is there anyway to have a rigidbody but still have that object fixed in place. It seems when you have a collision you must have at least one of them be a rigidbody. My one objcect is using a pathfinder and having a rigidbody messes with that. So im forced to make a wall object into a rigidbody to use OnTriggerEnter.... is there a work around?

Turn on isKinematic for the rigidbody you want not to move.

And in case you want to do it from a script:

Also you do not need a RigidBody to use onTriggerEnter - any collider will do.

Start here and you can read about all the colliders until the cows come home :)

And pertaining just to onTriggerEnter
