dataTree input to c# script

Hi all
just one simple question. How to read DataTree in C# component (GH 0.7.30). Exist some simple example for that? When i try something like this ... i get some part from input, but im not sure if is it correct way how to make it.

private void RunScript(Curve geom, Plane plnA, Plane plnB, ref object A)
{
    //your code here…
    DataTree<object> t = (DataTree<object>) plnB;
    Print(t.TopologyDescription);

    for (int i = 0; i < t.BranchCount; i++)
    {
      GH_Path path = t.Path(i);
      for(int k = 0; k < path.Length; k++)
      {
        Print("[" + i + ";" + k + "] " + t[path, k].ToString());
      }
    }
}

Hi Jachym
you have to set the var to datatree access when you declare it outside
than you have full datatree access
hope that helps



private void RunScript(DataTree srf, Point3d pt, ref object A)

{

//e.g.

int Bcount;

Bcount=srf.BranchCount();

}

Hi to]

WOW, how did you make it. I set like input for plnB TreeAccess -> Plane but in editor is it still like Plane. How can i change it to DataTree?

Hi Jachym,

have a look in these two examples - they show how to read or make a tree. Like Thomas is saying, you will need the component from here to open the file correctly.

Hope it is useful,
