About this Mod

I dunno what else to tell you, it adds a hotbar swapping mechanic.

You simply press the keybind, and you can scroll through your inventory rows with my handy dandy little gui, and then releasing the keybind will swap your hotbar with that inventory row.

Frequently Asked Questions

Hotbar Swap server crashes on startup – what to do?

Most common cause: wrong fabric 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 (1.21.11). You can switch loaders with one click in the panel.

Is Hotbar Swap compatible with fabric?

Hotbar Swap officially supports fabric for Minecraft 1.21.11. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with Hotbar Swap – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Hotbar Swap 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.
