WorldGrid

public static class WorldGrid

Grid arithmetic shared by the streamer, the editor tooling and Nebula's container integration.

Methods

Morton

public static ulong Morton(Vector3Int c);

Z-order (Morton) key of a coordinate: sorting cells by this key puts spatial neighbours next to each other in one dimension, which is what makes contiguous runs of cells compact regions.

Neighborhood

public static void Neighborhood(Vector3Int center, int radius, ICollection<Vector3Int> result);

Every coordinate within radius cells of center on every axis (a cube; radius 0 = just the centre).

Rings

public static int Rings(Vector3Int a, Vector3Int b);

Chebyshev distance between two coordinates (how many rings apart).

AreAdjacent

public static bool AreAdjacent(Vector3Int a, Vector3Int b);

The 26 coordinates that share a face, edge or corner with c.
