GeNa align object to spline

[Lenar]

Hi,

I need to align some objects along spline, as I understand I need to write my own GeNa spawn extension, but it's too difficult for me, I just want simple script to align object at spline node, with some parameters. 

1. How can I find any event on spline modified?

2. How to find node direction Node.Roll not working properly

    [SerializeField]
    Spline genaSpline;
    [field: SerializeField]
    public Spline GeNaSpline { get => genaSpline; private set => UpdateGeNaSpline(value); }

    [Range(0,100)]
    public int NodeID;
    public float XOffset;
    public float DistanceOffset;

    void UpdateGeNaSpline(Spline value)
    {
        //if new Spline assigned clear old dependencies, add listener to spline modify event 
        genaSpline = value;
        UpdatePosition();
    }

    void UpdatePosition()
    {
        if (!genaSpline) return;
        if (NodeID>=0 && NodeID<genaSpline.Nodes.Count)
        {
            GeNaNode node = genaSpline.Nodes[NodeID];
            Vector3 pos = node.Position;
            pos = pos+Quaternion.AngleAxis(node.Roll, Vector3.up) * Vector3.forward* XOffset;
            Terrain ter = Terrain.activeTerrain;
            if (ter)
            {
                TerrainCollider col = ter.GetComponent<TerrainCollider>();
                Ray ray = new Ray(pos + Vector3.up * 100f, Vector3.down);
                RaycastHit hit;
                if (col.Raycast(ray, out hit, 200f))
                {
                    pos = hit.point;
                }
            }
            transform.position = pos;
        }
    }

            GeNaNode node = genaSpline.Nodes[NodeID];
            Vector3 pos = node.Position;
            GeNaCurve genaCurve = genaSpline.GetCurveFromNode(node);
            GeNaSample genaSample = genaCurve.GetSample(0.5f);
            pos = pos + genaSample.Right.normalized * NodeOffset;
            

So I found a solution for node offset, but still can't find event than spline is modified. please help, for now I just call UpdatePosition on Update

Thanks @Manny, but this won't work after add/remove nodes. I think in this case I'd better leave it as it is and will call UpdatePosition on some time interval. Anyway thanks!

How do I get a point between Node A and Node B? I thought it would be modifying the value of GetSample (normalized between 0 and 1) but it doesn't work, can you give me some extra hints please? 

genaCurve.GetSample(0.5f);
