About this Mod
Crash minecraft with only 1 command instantly, on any PC
Have you ever thought of purposefully crashing minecraft with 1 command, for a cool effect for horror maps or just to prank your friends? Well this is a simple datapack I made to achieve this.
Run this command to crash the game:
/function ant:crash
The crash is not making lags on purpose or out of memory stuff, it is reusable, so you can safely join your world again after a crash and everything will probably be fine.
This datapack was made by using a worldgen bug MC-264777, so the function just loads a chunk in a custom void dimension that has noise settings height defined bigger than the max build height. The datapack can be installed both during world creation and to an existing world, but you need to re-enter your world 1 time after installing in an existing already loaded world, /reload won't work. Before entering a world with this datapack you will see a warning.
Keep in mind that because it's a bug, this can be fixed in future versions, and any mod may fix the crash or make things even worse. For example Concurrent Chunk Management Engine mod will break the datapack.
I strongly recommend to make backups of your important worlds before installing this datapack to them, because even tho my tests show that everything is fine, every type of crash may damage your world.
