Question by Demian-Wright · Jan 21, 2017 at 07:25 PM · physics2dcollider2dphysicmaterial

Using a different physic material on a single object depending on the object colliding with it?

I've search around and haven't found a way to do this. I want to apply two different 2D physic materials to a single object and use the properties (friction and bounce) of only one of them, depending on the object (tag) that is colliding with it. Imagine the following scenario:

The player has spike boots. The player pushes a box on top of a slanted frictionless ice surface. The box slides down as expected, but the player does not slide at all.

I'm fairly certain that this can't be done through the UI so I will be needing some C# code accomplish this. I can access the name of the physic material through Collision2D.collider.sharedMaterial.name in the OnCollisionStay2D(Collision2D) function but how do I tell Unity's physics engine to ignore this material for this collision?
