Creating default value for list input

Hi guys,

I'm wondering if its possible to assign a default value to a list input. Let's say I just make a very simple component that creates a sphere from a list of points and doubles (the radius).

I would then have the input as:

pManager.AddPointParameter("Points", "P", "Base points for spheres", GH_ParamAccess.list);

pManager.AddNumberParameter("Radius", "R", "radius of sphere", GH_ParamAccess.list);

But what if I want to assign 10 as radius if nothing else is declared. If I had an item-input I would just write:

pManager.AddNumberParameter("Radius", "R", "radius of sphere", GH_ParamAccess.item, 10.0);

How does this work with lists?

Hi Timo,

there's two different concepts here. "But what if I want to assign 10 as radius if nothing else is declared." refers to optional parameters. If there is no data, the SolveInstance method will just use 10 as a default. I don't think this is what you want.

You'll have to cast your parameter to Param_Number and populate the PersistentData:
