Hi, I want to do pathfinding on server. How to export navmesh data include vertices and indices?

Hi

Which graph type are you using?

#3

I used navmesh graph.

    List<Vector3> verticesList = new List<Vector3>();
    List<int> indicesList = new List<int>();

    for (int i = 0; i < AstarPath.active.graphs.Length; ++i)
    {
        NavGraph graph = AstarPath.active.graphs[i];

        graph.GetNodes(node =>
        {
            var triangleNode = node as TriangleMeshNode;

            Int3 a, b, c;
            triangleNode.GetVertices(out a, out b, out c);

            verticesList.Add(new Vector3(a.x, a.y, a.z));
            verticesList.Add(new Vector3(b.x, b.y, b.z));
            verticesList.Add(new Vector3(c.x, c.y, c.z));

            indicesList.Add(triangleNode.v0);
            indicesList.Add(triangleNode.v1);
            indicesList.Add(triangleNode.v2);
        });
    }

Why the index is wrong?

@aron_granberg Please help me!

Hi

If you are using a navmesh graph, the source already comes from a mesh. So why do you need to create a graph out of it and then export it again?
