Number sequences produced by math.randomseed(seed) are platform dependent.. any solutions?

So I am making a game in which I use math.randomseed() to generate levels randomly, but that are the same through each play. This saves me the time of creating levels by hand as long as my level generation algorithm works fine, which it does. However, my levels generate completely differently on Android and the Windows simulator using the same seed.

I Googled the issue and found this on the Beer SDK forums:

Does anyone know a similar workaround for Gideros?

Hi,

The random number generator is platform dependent. But you can use a good quality random number generator like Mersenne twister. So that you can get both a platform independent and higher-quality pseudorandom generator.

And https://love2d.org/forums/viewtopic.php?f=5&t=3424 has a pure Lua Mersenne twister.

ah thanks @atilim I will look into this!

Works great! Attached is the Lua file I based my work off of for others to use.
