Click the cat to generate random numbers. Use the custom blocks to generate random numbers! This custom psuedo-random number generator uses seeds! That means you can use the same seed and get the same list of "random" numbers! I am going to use this for procedural generation, so that you can save the level seed, and that will generate the same level each time. If you need numbers with decimal places, e.g. between 1.0 and 10.0, just pick random between 10 and 100 and divide by 10.
