MrCrayfish‘s Vending Machine Mod allows players to implement working Vending Machine to Minecraft. This machine is quite functional. Rather than purchasing items through villagers, now players can get these items through Vending Machine.
With Vending Machine, you just simply use emeralds collected in-game, and purchase a large number of items with a reasonable price, including food, blocks, potions, and rare items such as Nether (Nether Wart, Ghast Tear and etc) or The Void (Elytra and etc).
