Description

Creates a new material.

Note that although this function lets you create a new physics material from a script, it is generally easier to create and assign the material from the editor.

using UnityEngine;

public class Example : MonoBehaviour
{
    Collider coll;

    void Start()
    {
        coll = GetComponent<Collider>();

        PhysicsMaterial material = new PhysicsMaterial();
        material.dynamicFriction = 1;
        coll.material = material;
    }
}

Description

Creates a new material named name.
