Fish No Stuck
There is nothing quite as immersion-breaking in an otherwise beautiful underwater biome as staring at a school of fish that refuses to move. You expect them to dart away as you approach or swim in coordinated patterns, but instead, they sit frozen in place like decorative statues. This frustrating phenomenon is caused by a long-standing bug in the game's code, specifically identified as MC-182763. Fortunately, the community has rallied to create a solution. The Fish No Stuck add-on is a lightweight modification designed to rectify this specific artificial intelligence failure, ensuring your aquatic life behaves exactly as nature intended.
Understanding the Frozen Fish Glitch
To appreciate what this fix does, it helps to understand why the problem occurs in the first place. In vanilla Minecraft, fish utilize a complex system called the FollowFlockLeaderGoal. This system attempts to organize fish into schools by selecting a leader and assigning followers to trail behind them. However, a logical error in the code can cause a leader fish to be incorrectly added to its own follower list. When this happens, the leader stops moving entirely, and because every other fish in the school is programmed to follow the leader, the entire group becomes paralyzed.
This state persists indefinitely unless specific conditions are met, such as a player hitting the fish or switching game modes to survival and swimming directly into them. For players who enjoy building elaborate aquariums or exploring deep ocean trenches, this bug ruins the dynamic feel of the water. The Fish No Stuck mod intervenes by applying a critical patch to the FollowFlockLeaderGoal logic. It checks the nearest fish to determine if it is truly a leader before adding it to a follower list, preventing the circular reference that causes the freeze.
Additional AI Improvements
Beyond the primary fix for stationary schools, this modification addresses several subtler issues within the fish entity behavior. Another significant correction involves the entity predicate check used in the avoid entity goal. The mod updates this to use EntitySelector.NO_CREATIVE_OR_SPECTATOR instead of the standard EntitySelector.NO_SPECTATORS. This ensures that fish react appropriately to players in creative mode, maintaining consistent behavior regardless of your current gameplay style.
Furthermore, the add-on sets the checkNoActionTime parameter to false within the FishSwimGoal. This change prevents individual fish from getting stuck at their current coordinates due to internal timer errors. The mod also dynamically adjusts the school size; if a follower fish is killed, the leader's school size count decreases accordingly, maintaining accurate group dynamics. While these changes do not drastically improve overall game performance, they eliminate minor lag spikes associated with broken entity calculations and ensure a smoother visual experience underwater.
Compatibility and Installation Guide
If you are wondering how to install this essential fix, the process is straightforward for most modded setups. The Fish No Stuck for Minecraft is currently supported on versions ranging from 1.17.x through 1.20.x. It is primarily built for the Fabric loader, though there is often compatibility with Quilt due to their shared architecture. Forge users should check specific repository branches for potential ports, as the core logic remains adaptable across different loading environments.
For those who prefer a streamlined setup process without manually digging through mod folders, tools like the foxygame.net launcher can simplify things significantly. This innovative launcher features a comprehensive add-on catalog where you can locate Fish No Stuck and enable it with a single click, automatically handling version compatibility and dependency checks for you. This removes the hassle of matching exact file versions and allows you to jump straight into your corrected ocean biomes.
- Download the correct version of the mod file for your game version.
- Ensure you have either Fabric Loader or Minecraft Forge installed.
- Navigate to your Minecraft directory and open the "mods" folder.
- Drag and drop the downloaded jar file into the mods folder.
- Launch the game and verify that fish are swimming normally.
Why You Need This Mod
The decision to download Fish No Stuck comes down to preserving the atmosphere of your world. Minecraft's oceans are meant to be vibrant ecosystems teeming with life. When fish stop moving, the environment feels dead and static, detracting from the exploration experience. Whether you are constructing a massive underwater base, designing an aquarium map, or simply fishing for resources, having functional mob AI is crucial.
This mod does not add new items, change textures, or alter game mechanics beyond fixing the broken logic. It is a pure quality-of-life improvement that works silently in the background. By correcting the leadership assignment in fish schools and refining their avoidance behaviors, it restores the natural flow of the game. If you have ever been annoyed by a tank full of motionless cod or salmon, this small addition provides an immediate and permanent solution, letting you enjoy the underwater scenery exactly as the developers originally envisioned.
