Method Descriptions
-------------------

.. _class_NavigationMeshSourceGeometryData3D_method_add_faces:

.. rst-class:: classref-method

void **add_faces** **(** :ref:`PackedVector3Array<class_PackedVector3Array>` faces, :ref:`Transform3D<class_Transform3D>` xform **)**

Adds an array of vertex positions to the geometry data for navigation mesh baking to form triangulated faces. For each face the array must have three vertex positions in clockwise winding order. Since :ref:`NavigationMesh<class_NavigationMesh>` resources have no transform, all vertex positions need to be offset by the node's transform using ``xform``.

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

----

.. _class_NavigationMeshSourceGeometryData3D_method_add_mesh:

.. rst-class:: classref-method

void **add_mesh** **(** :ref:`Mesh<class_Mesh>` mesh, :ref:`Transform3D<class_Transform3D>` xform **)**

Adds the geometry data of a :ref:`Mesh<class_Mesh>` resource to the navigation mesh baking data. The mesh must have valid triangulated mesh data to be considered. Since :ref:`NavigationMesh<class_NavigationMesh>` resources have no transform, all vertex positions need to be offset by the node's transform using ``xform``.

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

----

.. _class_NavigationMeshSourceGeometryData3D_method_add_mesh_array:

.. rst-class:: classref-method

void **add_mesh_array** **(** :ref:`Array<class_Array>` mesh_array, :ref:`Transform3D<class_Transform3D>` xform **)**

Adds an :ref:`Array<class_Array>` the size of :ref:`Mesh.ARRAY_MAX<class_Mesh_constant_ARRAY_MAX>` and with vertices at index :ref:`Mesh.ARRAY_VERTEX<class_Mesh_constant_ARRAY_VERTEX>` and indices at index :ref:`Mesh.ARRAY_INDEX<class_Mesh_constant_ARRAY_INDEX>` to the navigation mesh baking data. The array must have valid triangulated mesh data to be considered. Since :ref:`NavigationMesh<class_NavigationMesh>` resources have no transform, all vertex positions need to be offset by the node's transform using ``xform``.

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

----

.. _class_NavigationMeshSourceGeometryData3D_method_clear:

.. rst-class:: classref-method

void **clear** **(** **)**

Clears the internal data.

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

----

.. _class_NavigationMeshSourceGeometryData3D_method_get_indices:

.. rst-class:: classref-method

:ref:`PackedInt32Array<class_PackedInt32Array>` **get_indices** **(** **)** |const|

Returns the parsed source geometry data indices array.

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

----

.. _class_NavigationMeshSourceGeometryData3D_method_get_vertices:

.. rst-class:: classref-method

:ref:`PackedFloat32Array<class_PackedFloat32Array>` **get_vertices** **(** **)** |const|

Returns the parsed source geometry data vertices array.

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

----

.. _class_NavigationMeshSourceGeometryData3D_method_has_data:

.. rst-class:: classref-method

:ref:`bool<class_bool>` **has_data** **(** **)**

Returns ``true`` when parsed source geometry data exists.

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

----

.. _class_NavigationMeshSourceGeometryData3D_method_set_indices:

.. rst-class:: classref-method

void **set_indices** **(** :ref:`PackedInt32Array<class_PackedInt32Array>` indices **)**

Sets the parsed source geometry data indices. The indices need to be matched with appropriated vertices.

\ **Warning:** Inappropriate data can crash the baking process of the involved third-party libraries.

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

----

.. _class_NavigationMeshSourceGeometryData3D_method_set_vertices:

.. rst-class:: classref-method

void **set_vertices** **(** :ref:`PackedFloat32Array<class_PackedFloat32Array>` vertices **)**

Sets the parsed source geometry data vertices. The vertices need to be matched with appropriated indices.

\ **Warning:** Inappropriate data can crash the baking process of the involved third-party libraries.
