Node for 3D tile-based maps.
    public class GridMap : Spatial

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 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 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.

Properties

    public bool CellCenterX { get; set; }

If true grid items are centered on the X axis.

    public bool CellCenterY { get; set; }

If true grid items are centered on the Y axis.

    public bool CellCenterZ { get; set; }

If true grid items are centered on the Z axis.

    public int CellOctantSize { get; set; }

The size of each octant measured in number of cells. This applies to all three axis.

    public float CellScale { get; set; }

    public Vector3 CellSize { get; set; }

The dimensions of the grid’s cells.

    public int CollisionLayer { get; set; }

    public int CollisionMask { get; set; }

    public MeshLibrary Theme { get; set; }

The assigned MeshLibrary.

Methods

    public void Clear()

Clear all cells.

    public void ClearBakedMeshes()

    public Array GetBakeMeshes()

    public RID GetBakeMeshInstance(int idx)

    public int GetCellItem(int x, int y, int z)

The MeshLibrary item index located at the grid-based X, Y and Z coordinates. If the cell is empty, INVALID_CELL_ITEM will be returned.

    public int GetCellItemOrientation(int x, int y, int z)

The orientation of the cell at the grid-based X, Y and Z coordinates. -1 is retuned if the cell is empty.

    public int GetCollisionLayer()

Getter for CollisionLayer

    public bool GetCollisionLayerBit(int bit)

    public int GetCollisionMask()

Getter for CollisionMask

    public bool GetCollisionMaskBit(int bit)

    public Array GetMeshes()

Array of Transform and Mesh references corresponding to the non empty cells in the grid. The transforms are specified in world space.

    public int GetOctantSize()

Getter for CellOctantSize

    public MeshLibrary GetTheme()

Getter for Theme

    public Array GetUsedCells()

Array of Vector3 with the non empty cell coordinates in the grid map.

    public void MakeBakedMeshes(bool genLightmapUv = false, float lightmapUvTexelSize = 0.1f)

    public Vector3 MapToWorld(int x, int y, int z)

    public void ResourceChanged(Resource resource)

    public void SetCellItem(int x, int y, int z, int item, int orientation = 0)

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.
