This datapack changes the world seed every 5 minutes, regenerating the entire world. However, your inventory, health, and most importantly position is kept the same. You may spawn inside a wall, or in the air!
This datapack requires the Multiverse mod to work.
How it works
At the beginning, you spawn in the vanilla Overworld dimension. However, it also generates 6 new dimensions: overworld_a, nether_a, end_a, overworld_b, nether_b, and end_b. Each extra dimension is generated with a random seed.
When the timer runs out the first time, you are teleported to overworld_a. After that, you alternate between the A set of dimensions and the B set of dimensions. (For example, if you're in nether_b when the time runs out, you'll be teleported to nether_a.)
Each time you teleport, the set of dimensions you just left are deleted and re-created with new random seeds. (So when you teleport from an A dimension to a B dimension, all three A dimensions are regenerated.) This ensures that each time you switch dimensions, you get a new world with a new random seed.
