AutoFish for Everyone!

This mod is probably the most accurate among all automatic fishing mods.
It should also be fully compatible with other mods, since Mixin usages are avoided.
It is fully client-sided and works on vanilla servers (and should also work on other servers, but I didn't test it.)

Usage

Go to control and set the keybind
Use the keybinds to toggle on/off the mod and its features
Open the GUI to set the recast/reel in delay* (in ticks) and item filter**
Throw your bobber into the water and it will do its thing.

*Optional and only works with version 1.1.0+
**Does not work in multiplayer

About public servers, it is not recommended to use this as the mod provides unfair advantages. Use this at your own risk. If you get banned, it is NOT my fault.
You should only use this in singleplayer or private servers.

The Reason Behind

Because of the 1.16 update. Mojang nerfed AFK fish farms by removing the chance of getting treasures in old designs.
There were some new designs, but they are not as good as the old ones.
To solve this problem, I made this mod.
With this mod, you will be able to AFK fish in 1.16, while still getting the treasures.

The Mechanic Behind

It is a very simple solution. As everyone knows, casting your fishing rod will spawn a bobber. This mod tracks the motion of the bobber. When the vertical motion of the bobber is low enough, we know it catches a fish, so we retract it and BAM! You got your reward.
