WaterSaver
by Damir00109
When the game window loses focus, WaterSaver makes the player's character jump so drowning is avoided, a fix for players who step away from Minecraft while in water.
What it does
WaterSaver detects when the game window loses focus, for example after a minimized window or a switch to another program. While the window is inactive, the mod sends a jump press so the character keeps surfacing instead of drowning. The protection stays in place until the game is brought back to the front.
The mod only affects the character in water and needs no setup, since it works out of the box. It is a Fabric mod for version 1.21.8 and is released under All rights reserved, so the code is not open source. Public links for its source code and issue tracker exist. Files for 1.21.8 were first published on 2025-11-24 and last updated on 2025-11-25, with 0.5.3 as the latest file.
Key features
Automatic focus detection
The mod notices when the game loses focus without any manual toggle, so it covers sudden minimizing as well as switching programs.
Simulated jump input
While the window is inactive, a jump key press is simulated, which keeps the character afloat in oceans and rivers.
No configuration needed
Installation is enough. Nothing needs to be set up, so the mod works from the first launch.
Compatible with other mods
The mod is built to coexist with other mods without interfering with gameplay.
Compatibility

Use cases
Long swims and water travel
Players crossing oceans or rivers can leave the game running in the background without losing their character to drowning.
Multitasking with urgent messages
A player who gets an urgent message and minimizes the window does not have to return to the game to avoid losing the character in water.
Who it’s for: Players who use Minecraft on a client and often minimize the window while traveling across water, or who want protection from a sudden exit to the desktop.
