Function NavmeshBase.GetTile

NavmeshTile GetTile (

int	x
int	z

)

Tile at the specified x, z coordinate pair.

The first tile is at (0,0), the last tile at (tileXCount-1, tileZCount-1).

var graph = AstarPath.active.data.recastGraph;
int tileX = 5;
int tileZ = 8;
NavmeshTile tile = graph.GetTile(tileX, tileZ);

for (int i = 0; i < tile.nodes.Length; i++) {
// ...
}
// or you can access the nodes like this:
tile.GetNodes(node => {
// ...
});
