what about class that can access random() or something like that or you maybe can use time if time were even do this or time were odd do that? you can do rng by yourself doing that but thats predictable
i had seen about puzzlescript and it was html5 libraries. So i do have a bit knowledge about html5. Basically you need to use Math.floor() to round up the Math.Random() so the codes it looks like this
Math.random() //<< it returns double number from 0 - 1. example 0.189281, 0.83823, 0.90823879, 0.49874965
Math.floor(Math.random() * 10); //<< return a number 0 - 9
function getRndInteger(min, max) {
return Math.floor(Math.random() * (max - min + 1) ) + min;
} //<< this return an int number with threshold
i found it at this place
