Trying to enable C# components for my Add-on

So, I’m trying to figure out how to let people write their own C# components against T-Splines. There is a lot more functionality exposed to C# than I’ve had time to write components for yet.

The very simple node I have tried to make has a single input T-Spline, and then it tries to output the number of verts in that T-Spline.

Here’s the code:

  private void RunScript(object TS, ref object A)
  {
    TSplines.Surf surf = TS.Value;
    A = surf.getVertCount();
  }

and the error message I get is:

Error: The type or namespace name ‘TSplines’ could not be found (are
you missing a using directive or an assembly reference?) (line 89)
Error: ‘object’ does not contain a definition for ‘Value’ (line 89)

So it seems like the way to fix it is to add #using TSplines up at the top. But there’s no way that I can figure out how to do that, since editing is disabled up there. Also, I’m not super familiar with how C# namespacing works, but it seems like there might need to be something else that happens, adding the reference or whatnot.

Is there any hope for this?

Hi Tom,

In PanelingTools for GH, I expose PT library to be used in scripting components. See attached example.
I added a note to show how you can add the assemblies to the scripting component.

Is that what you are looking for?

Looks like that does it. Thanks… :smile:
