When my Player 1 character collides with Player 2, the other player moves in that direction until stopped. This works Vice Versa as well.
I suspect this is an issue with the rigid body.
How can I prevent this from happening?

Is there friction? (floor physics material)

No, currently the floor is dictated by a if y is lower than -1 set y to -1.

#

I'm unsure how to switch to a friction system

Rigidbody physics with kinematic or regular?

#

Assuming you're using non-kinematic, you'd just add a collider to the floor and some material with friction (the base physics material has a bit of friction)

#

Else if you've got your own custom gravity/grounded/friction/physics-system-overall you'll have to implement your own dampening to slow the speed down if grounded etc

I'll have to look into this in the morning since it's gotten late for me.
I'll update then, thank you.

also check linear damping

I'm using a non-kinematic rigidbody.
If I set 'Is Trigger' to false on the floor they stop after about 2 units of movement when I hold the button.
This occurs rather or not the Physics mod is active.
I was looking at other damping solutions but they stop movement elsewhere when I'm just trying to stop the momentum transfer.
