Auto Fisher Pro
by nullstilles
Auto Fisher Pro is a client-side Fabric utility that automates fishing, including rod switching, junk filtering and bite detection.
What it does
The mod runs on the Fabric loader and is client-side only, so only the player's client needs it and servers do not. It depends on Cloth Config API, Fabric API and Mod Menu, which must all be installed alongside it. Files cover 1.21.1 – 1.21.11 across eleven release versions, with 1.0.0 for 1.21.11 as the latest file, and the license is All rights reserved, so the mod is not open source, though its source code is publicly available.
Once a player holds a fishing rod near water, the mod casts and reels in automatically. Bite detection combines three checks: the server's caught-fish flag, a baseline drop based on Y-level, and a velocity spike in the sensor, which lets the mod react at the exact tick a bite happens. Delays between actions are randomized to avoid predictable timing patterns.
Key features
Automatic fishing loop
The mod casts and reels in on its own while the player stands near water with a rod in hand.
Three-layer bite detection
A caught-fish flag, a Y-level baseline and a velocity spike check are combined to catch bites on the exact tick.
Rod switching
When the current rod is close to breaking, the mod scans the inventory and swaps in a fresh one, so an enchanted rod is not lost.
Junk item filter
Configurable lists of unwanted items are filtered out of the catch, and the lists can be edited in the settings screen.
