Chunk Swap
Every selected number of seconds, the chunk you are standing in will swap with a new chunk in the same dimension
⬇ Download on Modrinth⚡ ChunkSwap
The world beneath your feet can't be trusted. Every few seconds, the chunk you're standing on gets replaced with a completely random chunk from somewhere else in the world. You stay exactly where you are — but everything around you changes instantly.
What does it do?
When the timer hits zero, the 16×16 chunk you're standing in is swapped with a random chunk pulled from somewhere else in the same dimension. One second you're in a forest. The next you're on a cliff edge, in the middle of an ocean, inside a village, or hovering over a ravine. Terrain, structures, chests, spawners, ores — all of it swaps instantly. You never know what's coming.
