This datapack sets you to one heart! You're as brittle as glass!!

📥Installation:

This datapack sets you to one heart and removes the other 9 hearts! The pack is made for all versions and snapshots between 1.18.2 and 26.1.1.

⚠️It is recommended to add the datapack by clicking on "Open Pack Folder" and then pasting the datapack inside that folder! Putting it in the /datapacks folder of your world or modpack also works but is less reliable...

Or, use the mod and put it in your /mods folder!

Or, use the plugin and put it in your server's /plugins folder!

Frequently Asked Questions

One Heart! server crashes on startup – what to do?

Most common cause: wrong bukkit version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 3 GB RAM is allocated and the loader matches the mod version (26.1.1). You can switch loaders with one click in the panel.

Is One Heart! compatible with bukkit and datapack and fabric and forge and neoforge and paper and purpur and quilt and spigot?

One Heart! officially supports bukkit, datapack, fabric, forge, neoforge, paper, purpur, quilt, spigot for Minecraft 26.1.1, 26.1, 1.21.11. Note: Forge and Fabric mods are NOT cross-compatible – pick one loader and stick with it. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with One Heart! – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if One Heart! consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
