I wanted one of these so I could generate an Array and then select an element from within it at random. Seems more broadly applicable than that, of course. :smiley:

TheSeamau5 commented 9 years ago

Oh, quick tip, if you want a random generator that always generates the same value, there's constant.

You don't need to say, Random.float 0 0 you can just do Random.constant 0

Ah! Good to know. I figured there was something like that, but didn't know what it was called. Changed to constant in c69d079a0df116d9adf9601afd4a7dbfd2f5824f

Cool, thanks. This is a pretty useful investigator.
