Function component?

It’s me again. I need to know what new component to substitute for the obsolete function component in the attached file. Function_spiral.ghx (64.3 KB)
Somehow or other, I need to figure out how to wrap my mind around how to find things in Grasshopper. I’m not doing well with it. The Grasshopper Components page at looked very promising but now I’m finding it not well organized for finding things.

‘Maths | Script | Evaluate’

Yes, I had managed to find it myself. Whoever wrote the note on the pop-up window about zooming in to be able to edit may have thought they were being funny, but I didn’t find much friendliness in the last line

This window will show one more time, then you are on your own.

One of the ways that I found useful when learning GH, (and how I was taught), was to consider what type of operation I was doing. (sounds potentially insulting, I’ll elaborate a bit).

In looking at the NATIVE tabs that come with GH, it can help to think of them like this.

  • Params → These store stuff, (for the most part). They don’t perform any functions/actions on geometry/Data. ALL of the other Tabs will contain components to “do stuff”. (exception in this description would be a few items in the Util group, primarily Galapagos.)

  • Maths → Most anything to do with mathematical operations, (granted, the domains group used to be on the sets tab…I think, but in general, fairly self explanatory.)

  • Sets → Lists of data and data structure stuff.

  • Vector->All things vector. This can be thought of as the things defined by a vector, things that make up a vector, and point stuff. Probably easiest to assume that if a vector can be defined by a starting point, direction, and magnitude…then anything to do with those items will be found on this tab.

  • Curve/Surface/Mesh/Intersect/Transform ->…I think these are pretty straight forward?

  • Display → for the most part, these are graphical representations of already existing data, with the exception of colour I guess…which you can use to create colors from various data inputs.

Lastly, if you happen to have a component already on the canvas, and you don’t know what tab it came from, you can use ctrl + alt + left mouse button to show a tooltip style hint about what tab it’s located on. (on windows, I don’t know the equivalent Mac key combo).
