GridMap lets you place meshes on a grid interactively. It works both from the editor and from scripts, which can help you create in-game level editors.
|
|
GridMaps use a [MeshLibrary] which contains a list of tiles. Each tile is a mesh with materials plus optional collision and navigation shapes.
|
|
A GridMap contains a collection of cells. Each grid cell refers to a tile in the [MeshLibrary]. All cells in the map have the same dimensions.
|
|
Internally, 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.
|
|
[b]Note:[/b] GridMap doesn't extend [VisualInstance3D] and therefore can't be hidden or cull masked based on [member VisualInstance3D.layers]. If you make a light not affect the first layer, the whole GridMap won't be lit by the light in question.
