Ultra Hardcore (UHC) is a Minecraft PvP custom gamemode first thought up by the Mindcrack SMP group. This data pack allows for the easy setup of UHC games.
To set up the UHC, download and install the datapack in the datapacks folder of your world. Use the command /function #uhc:admin_setup to initiate the pack. Use the book to configure the options. UHC Admins MUST be in creative mode for full functionality in the book. Once you have finished configuring and all players have joined, press the start button.
All titles and options within the book have explanations when hovering over them. The book is interactive. You can see your current settings at each edge of the lobby.
To uninstall the datapack, use /function uhc:admin/uninstall. Note: gamerules and world spawn will not be reverted to the pre-datapack state.
The best place to get support, submit feedback and generally discuss the pack is the discord server.
These are expansions to the core UHC data pack. They just need to be installed alongside the core pack in the datapacks folder.
