GLTFPhysicsShape
================

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

Represents a GLTF physics shape.

.. rst-class:: classref-introduction-group

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

Represents a physics shape as defined by the ``OMI_collider`` GLTF extension. This class is an intermediary between the GLTF data and Godot's nodes, and it's abstracted in a way that allows adding support for different GLTF physics extensions in the future.

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

.. _class_GLTFPhysicsShape_property_height:

.. rst-class:: classref-property

:ref:`float<class_float>` **height** = ``2.0``

.. rst-class:: classref-property-setget

- void **set_height** **(** :ref:`float<class_float>` value **)**
- :ref:`float<class_float>` **get_height** **(** **)**

The height of the shape, in meters. This is only used when the shape type is "capsule" or "cylinder". This value should not be negative, and for "capsule" it should be at least twice the radius.

.. rst-class:: classref-item-separator

----

.. _class_GLTFPhysicsShape_property_importer_mesh:

.. rst-class:: classref-property

:ref:`ImporterMesh<class_ImporterMesh>` **importer_mesh**

.. rst-class:: classref-property-setget

- void **set_importer_mesh** **(** :ref:`ImporterMesh<class_ImporterMesh>` value **)**
- :ref:`ImporterMesh<class_ImporterMesh>` **get_importer_mesh** **(** **)**

The :ref:`ImporterMesh<class_ImporterMesh>` resource of the shape. This is only used when the shape type is "hull" (convex hull) or "trimesh" (concave trimesh).

.. rst-class:: classref-item-separator

----

.. _class_GLTFPhysicsShape_property_is_trigger:

.. rst-class:: classref-property

:ref:`bool<class_bool>` **is_trigger** = ``false``

.. rst-class:: classref-property-setget

- void **set_is_trigger** **(** :ref:`bool<class_bool>` value **)**
- :ref:`bool<class_bool>` **get_is_trigger** **(** **)**

If ``true``, indicates that this shape is a trigger. For Godot, this means that the shape should be a child of an Area3D node.

This is the only variable not used in the :ref:`to_node<class_GLTFPhysicsShape_method_to_node>` method, it's intended to be used alongside when deciding where to add the generated node as a child.

.. rst-class:: classref-item-separator

----

.. _class_GLTFPhysicsShape_property_mesh_index:

.. rst-class:: classref-property

:ref:`int<class_int>` **mesh_index** = ``-1``

.. rst-class:: classref-property-setget

- void **set_mesh_index** **(** :ref:`int<class_int>` value **)**
- :ref:`int<class_int>` **get_mesh_index** **(** **)**

The index of the shape's mesh in the GLTF file. This is only used when the shape type is "hull" (convex hull) or "trimesh" (concave trimesh).

.. rst-class:: classref-item-separator

----

.. _class_GLTFPhysicsShape_property_radius:

.. rst-class:: classref-property

:ref:`float<class_float>` **radius** = ``0.5``

.. rst-class:: classref-property-setget

- void **set_radius** **(** :ref:`float<class_float>` value **)**
- :ref:`float<class_float>` **get_radius** **(** **)**

The radius of the shape, in meters. This is only used when the shape type is "capsule", "cylinder", or "sphere". This value should not be negative.

.. rst-class:: classref-item-separator

----

.. _class_GLTFPhysicsShape_property_shape_type:

.. rst-class:: classref-property

:ref:`String<class_String>` **shape_type** = ``""``

.. rst-class:: classref-property-setget

- void **set_shape_type** **(** :ref:`String<class_String>` value **)**
- :ref:`String<class_String>` **get_shape_type** **(** **)**

The type of shape this shape represents. Valid values are "box", "capsule", "cylinder", "sphere", "hull", and "trimesh".

.. rst-class:: classref-item-separator

----

.. _class_GLTFPhysicsShape_property_size:

.. rst-class:: classref-property

:ref:`Vector3<class_Vector3>` **size** = ``Vector3(1, 1, 1)``

.. rst-class:: classref-property-setget

- void **set_size** **(** :ref:`Vector3<class_Vector3>` value **)**
- :ref:`Vector3<class_Vector3>` **get_size** **(** **)**

The size of the shape, in meters. This is only used when the shape type is "box", and it represents the "diameter" of the box. This value should not be negative.
