A fun survival challenge were you can't go above y level 32, you still can in the nether and end. This datapack is inspired by the challenge ibxtoycat did: https://www.youtube.com/watch?v=zsQ-5Nt04Rc&list=PLe8AZ2rjfkpw15Z-CwYMcYp9hkoV3g7ak&ab_channel=ibxtoycat
How to set up the datapack:
Step #1 Create a world with the datapack enabled.
Step #2 Click the open to lan button in the game menu and enable cheats.
Step #3 Find a cave below y level 32 and place bed and set your spawn point.
Step #4 Go into survival mod and type /function cave:start (gives you a starter box and night vison for ten minutes) or /function cave:man (No starter box or night vision). After running the command you will not be able to go above y level 32.
Step #5 Leave and rejoin the world so lan is no longer enabled.
