WaterBucketAutoSave
by Kuroto_Shiro
WaterBucketAutoSave is a Fabric client mod that places a water bucket beneath a falling player to prevent fall damage.
What it does
When the player falls from a dangerous height, the mod detects the fall and places a water bucket from the ninth hotbar slot just before landing, a technique often called an MLG water bucket. Detection starts at drops of five or more blocks, and the mod stays idle in safe situations so it does not trigger on ordinary jumps. Once the player lands on solid ground, the mod removes the water and returns the original hotbar slot to its prior state.
The mod uses real water buckets from the player's inventory, so it does not create water out of nothing, and it needs no input once enabled. Whenever the mod switches on or actually catches a fall, the chat window prints a short line saying so. It is built for parkour, building and exploration, where accidental deaths interrupt progress. It is a client-side only mod: the server does not need it and can run without any server-side changes, and players can join a server without installing it.
The mod is published for Fabric only and has no other loader builds. It covers 15 release versions, 1.18 – 1.20.6, with 1.0.1 for 1.20.6 as the latest file. The code is not open source and the mod is released under All rights reserved.
