I think I may recall another plugin that allows seeded random
but the S plugin has a seeded random function.
if you've heard legends about how hard s is to use, fear not
the math functions are just as simple as the built in construct one
you just use the Seed Random Action
choose a seed, and then the series of random values you generate afterward will be the same next time you use the same seed
come to think of it, I think the seeding may actually seed the regular construct random as well, but the random function in s let's you choose a range of two values, to simplify the process
