Swim Fix

Few things break the flow of an underwater adventure like suddenly getting stuck. You are swimming through a cave, dodging a Drowned, and then, without warning, your character halts mid-water. You press forward, but nothing happens. This frustrating issue stems from a long-standing Minecraft bug, and the Swim Fix mod is the definitive solution.

This lightweight utility mod directly addresses the infamous MC-220390 bug, ensuring your swimming experience is as smooth as the surface of a calm ocean. If you have ever tried to navigate tight underwater passages or escape a mob while submerged, you know exactly how annoying this glitch can be. Let’s dive deep into what this mod does, how to get it, and why it is a must-have for any aquatic explorer.

Understanding the MC-220390 Swimming Bug

The issue, as documented on the official Minecraft Bug Tracker, occurs when you hit an entity while swimming underwater. The game momentarily changes your player hitbox from the "swimming" size to the "standing" size and then back. This brief shift in collision detection causes a significant problem: if you are trying to swim below a block, your character gets stuck.

Essentially, the game registers a collision with the block using the larger hitbox, even though you are actively using the smaller swimming hitbox. This leaves you trapped in the middle of the water, unable to move forward or backward. It is a classic case of a small code oversight creating a massive headache for players.

Why This Bug Ruins Gameplay

  • Combat Interruption: Hitting an enemy while swimming is a core part of underwater combat. This bug punishes you for engaging in it.
  • Exploration Halt: Navigating shipwrecks, ocean monuments, and underwater caves becomes a tedious chore when you constantly get stuck on the ceiling.
  • PvP Disadvantage: In multiplayer, getting stuck for even a second can mean the difference between victory and a trip back to your spawn point.

How Swim Fix Solves the Problem

Instead of relying on the vanilla game's flawed logic, Swim Fix patches the core collision check. It ensures that when you are in the swimming pose, the game only uses the swimming hitbox for collision detection. This prevents the "stuck" state from ever occurring, allowing for uninterrupted movement even when striking mobs or sprinting under low ceilings.

The mod is built using the Architectury API, which means it is optimized for performance and has a minimal impact on your game's tick rate. It works seamlessly in the background, so you can focus on the adventure rather than worrying about technical glitches.

Swim Fix for Minecraft: Compatibility and Loaders

This mod is designed for players on the latest versions of the game. Specifically, it supports Minecraft 1.21.1 and newer. If you are playing on a recent snapshot or a stable release within this range, you are good to go.

In terms of mod loaders, Swim Fix is available for both Fabric and NeoForge. This dual compatibility ensures that whether you prefer the lightweight speed of Fabric or the robust ecosystem of NeoForge, you can enjoy the fix without switching your entire mod setup. The mod is also licensed under LGPL-3.0, making it open-source and community-friendly.

Installation Requirements

Before you download Swim Fix, you need to ensure you have the appropriate loader installed. You will also need the Architectury API mod, as this is a dependency for the mod to function correctly. The installation process is straightforward:

  • Download the version of Swim Fix that matches your loader (Fabric or NeoForge).
  • Place the downloaded JAR file into your mods folder.
  • Ensure the Architectury API is also present in the same folder.
  • Launch the game and enjoy the fix.
