Hi, I am new to Unity and would like to program a code so that when my object touches “Ladder”, Friction is activated by PYM2D. Can someone help me and tell me how to programme?

public PhysicsMaterial2D PYM2D;
if(collision.gameObject.tag == "ladder")
        {
            ______
        }

You need to apply the PhysicsMaterial2D to the sharedMaterial field of the RigidBody2D.

GetComponent<RigidBody2D>().sharedMaterial = PYM2D;

Ideally you will save a reference to the RigidBody2D in a member variable so that you don’t need to GetComponent every time there is a collision.
