Function NavmeshBase.ToTileMeshes

TileMeshes ToTileMeshes (

IntRect?

tileRect=null

If specified, only tiles within this rectangle will be extracted. The rectangle is specified in tile coordinates starting at (0,0). If larger than the graph, it will be clamped to the graph's size.

)

Extracts tiles from the graph into a portable format.

This can be used for many things, for example world streaming or placing large prefabs that have been pre-scanned.

The extracted tiles will have the same world-space size as this graph's tiles. Navmesh cuts are not baked into the extracted tiles.

var graph = AstarPath.active.data.recastGraph;
var tileMeshes = graph.ToTileMeshes();
// Store as a byte array
var bytes = tileMeshes.Serialize();

// Later on, load it back
var tileMeshes2 = TileMeshes.Deserialize(bytes);

// Load the tiles back into the graph
AstarPath.active.AddWorkItem(() => {
graph.ReplaceTiles(tileMeshes2);
});
AstarPath.active.FlushWorkItems();
