Ok... I got totally sidetracked before I could think of a reasonable way to do this. I attached both my solutions for completeness sake.

But my opinion is that this should be easier to accomplish. I'll try and come up with some components that do a better job at this.

Hi David,

First, thank you for your extraordinary work.

Would it be possible to incorporate conditional functions in function blocks?
One could thus solve many problems without using script components.

Renzo

Hi Renzo,

I've been dragging my feet a bit with the scripting language in GH. I wrote it myself but it's not really something I want to keep on supporting as there seem to be better options available. However, switching to those will take a lot of work, especially as I cannot break syntax.

I can probably add an If() function, but for advanced conditionals I'll need to seriously rethink this whole approach.

Ok, adding an If() function was easy. It works as follows:

If(condition, A, B)

where A is returned if condition=true and B is returned if condition=false. Both A and B are evaluated though.

This is going to be very useful !
I'll use the somewhatLessHideousSolution.ghx eagerly waiting for this one ;)

but you could just do the same thing with a C#/VB component. i think thats what is great about those components you can write something simple like a if statement or as complex as you want

Hi Robert,

This version was presented in my script example.
