Numeric Constants
-----------------
- **INVALID_CELL_ITEM** = **-1** --- Invalid cell item that can be used in :ref:`set_cell_item<class_GridMap_set_cell_item>` to clear cells (or represent an empty cell in :ref:`get_cell_item<class_GridMap_get_cell_item>`).
Description
-----------
GridMap lets you place meshes on a grid interactively. It works both from the editor and can help you create in-game level editors.
GridMaps use a :ref:`MeshLibrary<class_meshlibrary>` which contain a list of tiles: meshes with materials plus optional collisions and extra elements.
A GridMap contains a collection of cells. Each grid cell refers to a :ref:`MeshLibrary<class_meshlibrary>` item. All cells in the map have the same dimensions.
A GridMap is split into a sparse collection of octants for efficient rendering and physics processing. Every octant has the same dimensions and can contain several cells.
Member Function Description
---------------------------

The :ref:`MeshLibrary<class_meshlibrary>` item index located at the grid-based X, Y and Z coordinates. If the cell is empty, INVALID_CELL_ITEM will be returned.
.. _class_GridMap_get_cell_item_orientation:
- :ref:`int<class_int>` **get_cell_item_orientation** **(** :ref:`int<class_int>` x, :ref:`int<class_int>` y, :ref:`int<class_int>` z **)** const
The orientation of the cell at the grid-based X, Y and Z coordinates. -1 is retuned if the cell is empty.

.. _class_GridMap_get_meshes:
- :ref:`Array<class_array>` **get_meshes** **(** **)**
Array of :ref:`Transform<class_transform>` and :ref:`Mesh<class_mesh>` references corresponding to the non empty cells in the grid. The transforms are specified in world space.
.. _class_GridMap_get_used_cells:

Set the mesh index for the cell referenced by its grid-based X, Y and Z coordinates.
A negative item index will clear the cell.
Optionally, the item's orientation can be passed.
