This uses a similar equation to the java random function. For example: In Minecraft, you can choose a seed upon starting a new world (or choose random seed which technically isn't random) and when you click create new world, you get a world that looks random. If you create another world with the same seed though, the world in a lot of ways will be the same because it use a random number generator from a seed. Scratch however, does not have a random number generator that you can use a seed for. That is why I made this! In order to use it, enter a seed, the amount of numbers you want (capped at 200,000) and watch it generate! the number will only go up to 2048 but will seem to be random.
I made this for games like Scratchy's Universe or other games similar to it that a seed would work with. Most games on scratch that have a seed just have preset worlds. Entering a seed picks from that list but this allows for it to be generated on the spot without the extra stored values!
