I set out to make stores in my world, and the way to do it was to create a "Gold" scoreboard. However, my world uses physical currency, such as gold nuggets, gold bars (ingots), diamonds, etc.. So in order to keep with lore continuity and allow players to cash in their gold and diamonds, I created a bank. I really like how this turned out, although it is a nightmare dealing with all the command blocks, and proximity limitations. But… glad it works. Now to convert every bank…
Also, thank you Mojang for putting in a warning screen for every single clickable tellraw command! It doesn't break immersion or anything!
