About this Mod

🖱️ OneMouse
OneMouse is a lightweight and powerful "Autoclicker" mod for Minecraft Fabric 1.21. Unlike standard autoclickers that only simulate mouse clicks, OneMouse allows you to automate any key on your keyboard or mouse using simple chat commands.

Whether you need to spam Left Click for mobs, hold Right Click to eat, or press Space to auto-jump — OneMouse handles it all.

✨ Features
Universal Support: Works with Left/Right/Middle mouse buttons and almost all keyboard keys (W, Space, Enter, Shift, etc.).

Flexible Timing: Set intervals in milliseconds (ms), seconds (s), minutes (m), or even hours (h).

Multi-tasking: Run multiple autclickers at the same time (e.g., auto-attack AND auto-jump).

Easy Commands: No complex GUIs, just simple chat commands.

🚀 How to use
The main command is /onemouse

Examples:
Auto Attack (Left Click): /onemouse left 600ms (Clicks the left mouse button every 600 milliseconds)

Auto Eat / Place (Right Click): /onemouse right 3s (Clicks the right mouse button every 3 seconds)

Auto Jump (Space): /onemouse space 1s

Auto Walk Forward (W key): /onemouse w 100ms

Stopping Tasks:
Stop a specific key: /onemouse left stop

Stop EVERYTHING: /onemouse stopall

ms = Milliseconds (e.g., 100ms)

Frequently Asked Questions

OneMouse 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 (1.21.8). You can switch loaders with one click in the panel.

Is OneMouse compatible with fabric?

OneMouse officially supports fabric for Minecraft 1.21.8. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with OneMouse – how to optimize performance?

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