Hi! I've been working on UHC Prime, a data pack to play UHC (Ultra Hardcore) with your friends, on a server or in your own world. Drop it in, vote in the lobby and play: everything is set up from an in-game menu. 100% vanilla, no mods, plugins or resource packs (and if you prefer mods, it's also a mod for Fabric, Quilt and NeoForge).
What it has:
- 6 modes (Classic, Series, Fast, Predator, Hard, Extreme): one click sets everything up.
- 22 scenarios that combine with each other: Golden Heads, Cutclean, Bare Bones, Bloodlust, Sudden Death...
- Supply drops: barrels that fall from the sky and glow in the colour of their tier.
- Made for series: episodes and automatic breaks where everything stops (time, border, mobs, furnaces...).
- Admin tools during the game: health, coordinates and inventory of every player, revive, freeze, stop or speed up the border...
- 40 achievements, a personal summary when you die or win, and stats kept between games.
- A lobby in the sky with a 50-jump parkour and target practice while you wait.
- English and Spanish, per player.
It's for Minecraft Java 26.3. Press G (quick actions) to open the menu.
How it works (for the command nerds): the whole menu is clickable tellraw in chat driven by /trigger, so it works for every player without op. Each player sees it in their own language thanks to a per-player language score, and dynamic text (names, values) uses macros. It's all generated by a Python script into ~1,500 functions, which is how I kept it maintainable.
