A deformable physics body. Used to create elastic or deformable objects such as cloth, rubber, or other flexible materials.

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

.. _class_SoftBody_property_areaAngular_stiffness:

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

+----------+----------------------------------+
| *Setter* | set_areaAngular_stiffness(value) |
+----------+----------------------------------+
| *Getter* | get_areaAngular_stiffness()      |
+----------+----------------------------------+

.. _class_SoftBody_property_collision_layer:

- :ref:`int<class_int>` **collision_layer**

+----------+----------------------------+
| *Setter* | set_collision_layer(value) |
+----------+----------------------------+
| *Getter* | get_collision_layer()      |
+----------+----------------------------+

The physics layers this area is in.

Collidable objects can exist in any of 32 different layers. These layers work like a tagging system, and are not visual. A collidable can use these layers to select with which objects it can collide, using the collision_mask property.

A contact is detected if object A is in any of the layers that object B scans, or object B is in any layer scanned by object A.

.. _class_SoftBody_property_collision_mask:

- :ref:`int<class_int>` **collision_mask**

+----------+---------------------------+
| *Setter* | set_collision_mask(value) |
+----------+---------------------------+
| *Getter* | get_collision_mask()      |
+----------+---------------------------+

The physics layers this area scans for collisions.

.. _class_SoftBody_property_damping_coefficient:

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

+----------+--------------------------------+
| *Setter* | set_damping_coefficient(value) |
+----------+--------------------------------+
| *Getter* | get_damping_coefficient()      |
+----------+--------------------------------+

.. _class_SoftBody_property_drag_coefficient:

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

+----------+-----------------------------+
| *Setter* | set_drag_coefficient(value) |
+----------+-----------------------------+
| *Getter* | get_drag_coefficient()      |
+----------+-----------------------------+

- :ref:`NodePath<class_NodePath>` **parent_collision_ignore**

+----------+------------------------------------+
| *Setter* | set_parent_collision_ignore(value) |
+----------+------------------------------------+
| *Getter* | get_parent_collision_ignore()      |
+----------+------------------------------------+

.. _class_SoftBody_property_pose_matching_coefficient:

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

+----------+--------------------------------------+
| *Setter* | set_pose_matching_coefficient(value) |
+----------+--------------------------------------+
| *Getter* | get_pose_matching_coefficient()      |
+----------+--------------------------------------+

.. _class_SoftBody_property_pressure_coefficient:

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

+----------+---------------------------------+
| *Setter* | set_pressure_coefficient(value) |
+----------+---------------------------------+
