# FishNoStuck
A small mod that fixes fish stop moving entirely [MC-182763](https://bugs.mojang.com/browse/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.

### Another fix in this mod is:
- Check entity predicate by using `EntitySelector.NO_CREATIVE_OR_SPECTATOR` instead of `EntitySelector.NO_SPECTATORS` in avoid entity goal.
- Set `checkNoActionTime` to `false` in `FishSwimGoal` 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](https://github.com/SteveKunG/FishNoStuck/issues/1)
### Installation
- Install Fabric Loader/MinecraftForge
- Copy mod into `mods` folder
### Backstory
I was working on [Fish of Thieves](https://github.com/SteveKunG/FishOfThieves) 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.
