Find surrounding hex nodes

General Grid graph
1

I am using a constantPath to find all the surrounding nodes of a specific node. Unfortunately, this does not return unwalkable nodes. Is there a way to do this?

Hi

You’ll have to go through these manually:

static readonly int[] hexagonNeighbourIndices = { 0, 1, 5, 2, 3, 7 };

List<GridNodeBase> GetNeighbours(GridGraph graph, int x, int z) {
	var neighbours = new List<GridNodeBase>();
	for (int i = 0; i < hexagonNeighbourIndices.Length; i++) {
		var dx = neighbourXOffsets[hexagonNeighbourIndices[i]];
		var dz = neighbourZOffsets[hexagonNeighbourIndices[i]];
		var nx = x + dx;
		var nz = z + dz;
		var node = graph.GetNode(nx, nz);
		if (node != null) {
			neighbours.Add(node);
		}
	}
	return neighbours;
}
