Press SPACE to generate a random seed, updating the case and making the alphabet different and therefore the codes different. Press Up-Arrow to input custom strings(alphanumerical) or numbers. If you want to enable more symbols(like Unicode characters), just add them tho the variable _alphabet. Your unique code is stored in Alphabet. There are a total of 1.087366 x 10^146 different unique keys! Or, you can make your own custom alphabet using whatever characters you desire!
If you use this engine, please give credit. https://www.youtube.com/channel/UCVL-N_JFTo8dVfiGCT118Ng There is an unfix-able(to the extent of my knowledge) bug: If you type in i and it searches through the list, it will pick the first i it finds, be it lowercase or UPPERCASE. This is due to scratch saying "i=I" is true. /\ UPDATE: Due to |, I have added a case slider. You must re-scramble to apply changes.
