PhysicsMaterial
===============

**Inherits:** :ref:`Resource<class_Resource>` **<** :ref:`RefCounted<class_RefCounted>` **<** :ref:`Object<class_Object>`

A material for physics properties.

Description
-----------

Provides a means of modifying the collision properties of a :ref:`PhysicsBody3D<class_PhysicsBody3D>`.

Properties

+---------------------------+------------------------------------------------------------+-----------+

Property Descriptions
---------------------

.. _class_PhysicsMaterial_property_absorbent:

- :ref:`bool<class_bool>` **absorbent**

+-----------+----------------------+
| *Default* | ``false``            |
+-----------+----------------------+
| *Setter*  | set_absorbent(value) |
+-----------+----------------------+
| *Getter*  | is_absorbent()       |
+-----------+----------------------+

If ``true``, subtracts the bounciness from the colliding object's bounciness instead of adding it.

----

.. _class_PhysicsMaterial_property_bounce:

- :ref:`float<class_float>` **bounce**

+-----------+-------------------+
| *Default* | ``0.0``           |
+-----------+-------------------+
| *Setter*  | set_bounce(value) |
+-----------+-------------------+
| *Getter*  | get_bounce()      |
+-----------+-------------------+

The body's bounciness. Values range from ``0`` (no bounce) to ``1`` (full bounciness).

----

.. _class_PhysicsMaterial_property_friction:

- :ref:`float<class_float>` **friction**

+-----------+---------------------+
| *Default* | ``1.0``             |
+-----------+---------------------+
| *Setter*  | set_friction(value) |
+-----------+---------------------+
| *Getter*  | get_friction()      |
+-----------+---------------------+

The body's friction. Values range from ``0`` (frictionless) to ``1`` (maximum friction).

----

.. _class_PhysicsMaterial_property_rough:

- :ref:`bool<class_bool>` **rough**

+-----------+------------------+
| *Default* | ``false``        |
+-----------+------------------+
| *Setter*  | set_rough(value) |
+-----------+------------------+
| *Getter*  | is_rough()       |
+-----------+------------------+

If ``true``, the physics engine will use the friction of the object marked as "rough" when two objects collide. If ``false``, the physics engine will use the lowest friction of all colliding objects instead. If ``true`` for both colliding objects, the physics engine will use the highest friction.
