hey y'all, I was wondering, what are the different types of randomize commands available in processing?

Processing has 2 basic random types, random(low,high) which gives a float between low and high randomly, and noise(...); which uses a perlin noise algorithm to give smoothly variable numbers depending on the coordinates passed in (e.g. if the coordinates only vary slightly, the result only varies slightly)

Both random and noise have "seed" functions which allow you to give a known setup, so that you'll get the same results each time (albeit still random), e.g. randomSeed(1234); println(random(0,1)); will always print the same number.

i got ya! the seeding thing seems like a useful tool to have as part of random. I had a quick look at the link, (I'll check it out properly when I'm not so strapped for time) sure looks complicated for my young programming brain!
Thank you
