The array alternative to Warmonger's selector looks like this...
Just be careful when making the links - the selection choice has to be linked to the 'Array Get' integer 'Index' first; then to the 'Get' trigger. If you do it the other way around, it will look in the array before the index is set correctly, and you'll get the wrong output.
Which method is best?
When you're offering the user a choice of fixed values, there's really nothing in it. So unless other parts of your design give you a reason to do it one way or the other, just choose whichever you find easiest.
Both ways are dead useful any time you need to choose from a list of values, as there are many different ways to get an integer 'Index' - so you can easily choose whatever kind of panel control you think will work best when using the plugin.
For my money, the little radio buttons are a great choice (as long as there is room on the panel!). A single mouse-click gets you instantly to any setting you want without having to call up a menu or step through all the in-between values - precisely why I don't like knobs for that kind of thing either!
Feel free to use any schematics and algorithms I post on the forum in your own designs - a credit is appreciated (but not a requirement).
Don't stagnate, mutate to create. Without randomness and serendipity the earth would be just another barren rock.
