FishNoStuck
A small mod that fixes fish stop moving entirely MC-182763
Support with Minecraft 1.17.x-1.20.x for Fabric (Quilt maybe?)/Forge
How it works
The fish has an AI Goal that scans for the nearest fish, which will randomly select a leader and followers. Then it will let the follower fish follow the leader.
This mod applies bug fix to FollowFlockLeaderGoal
by checking the nearest fish if it is a leader or not.
If not, it will add into the follower list.
If leader gets added into the follower list. A Fish Leader will stop and not go to anywhere along with their followers (Forever!). Unless you hit them or switch gamemode to survival and swim near them.
For Minecraft Bug Report, see: https://bugs.mojang.com/browse/MC-182763
Another fix in this mod is:
- Check entity predicate by using
EntitySelector.NO_CREATIVE_OR_SPECTATOR
instead ofEntitySelector.NO_SPECTATORS
in avoid entity goal. - Set
checkNoActionTime
tofalse
inFishSwimGoal
to fix fish getting stuck at the current position - Decreased
schoolSize
from leader fish if the follower fish is getting killed.
Performance Impact
This mod doesn't improve any game performance, or it has very minor impact, especially for fish. See FishNoStuck#1
Installation
- Install Fabric Loader/MinecraftForge

Backstory
I was working on Fish of Thieves by looking at FollowFlockLeaderGoal
and figure it out how it works, then convert it to use Brain
system.
By display debug data above an entity.
Then I realize something wrong. A fish with schoolSize=8
has property isFollower=true
and has a leader. Which it should not be possible.
So that's the beginning of this mod.
