OneMouse
by .muzancha
OneMouse is a Fabric client mod that automates mouse clicks and keyboard keys on a timer, started from chat commands.
What it does
Players type short chat commands to repeat a left click, right click, or a key press such as W, Space, Enter or Shift at a chosen interval. Intervals can be written in milliseconds, seconds, minutes or hours, for example 600ms, 3s or 1s. Several tasks can run at the same time, so an auto-attack and an auto-jump can be active together. Unlike plain autoclickers that only simulate mouse clicks, the mod also handles keyboard keys.
Players can stop one task by naming its key, for example onemouse left stop, or end every running task with onemouse stopall. The main command is onemouse. Players who need to spam a left click on mobs, hold a right click to eat, or keep auto-jump running without pressing Space can set these up without a configuration screen. The mod runs on the client, so it changes nothing on a server. The files are for Fabric and 1.21.8, and the mod is released as All rights reserved, so it is not open source.
Key features
Universal key support
Left, right and middle mouse buttons work, along with most keyboard keys such as W, Space, Enter and Shift.
Timing in four units
Intervals accept milliseconds, seconds, minutes and hours, so a task can repeat quickly or slowly.
Concurrent tasks
Several autoclick tasks can run at once, for example an attack loop together with a jump loop.
Chat command control
Each task is set with one short command, and a single stop command ends one key or every task.
