About this Mod

A small mod that adds a Keybind for dedicated Offhand use (by default Mouse 4) and a bindable Keybind for dedicated Mainhand use.
By default MCs handling for the Use(right-click) keybind is:

  • check for block interaction (buttons and co)
  • check for Mainhand interaction (check selected slot for interaction)
  • check for Offhand interaction

if an interaction is found the others are not checked. This Mods adds 2 more Keybinds into the game, allowing for eclusive

  • check for Mainhand interaction (check selected slot for interaction)

and an exclusive

  • check for Offhand interaction

this allows you for example to block while holding a trident or to not place offhand torches while building when using the dedicated keybinds

Im unsure if anticheats might not be happy about players beeing able to block while holding a bow/trident or similar. Use at own risk.

It does NOT allow you to execute two interactions at the same time! It just allows you to have more control over which interaction to use.

Frequently Asked Questions

Offhander 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 Offhander compatible with fabric and forge and neoforge and quilt?

Offhander officially supports fabric, forge, neoforge, quilt for Minecraft 1.21.11, 1.21.10, 1.21.9. 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 Offhander – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Offhander consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge.
