Fall Damage Predict
by Ragek34
Fall Damage Predict shows, while a player looks down from a ledge, whether a planned jump would be fatal, and marks the landing blocks on screen.
What it does
Before a jump, the client predicts the outcome of the fall from the height and the block below. The mod highlights the blocks the player is about to land on and indicates whether the landing is safe, so a drop can be judged before it is taken. Visual safety zones mark the spots where a fall would cost nothing and where it would be lethal.
Water and slime blocks are handled automatically: the prediction takes them into account, so a landing into water or onto a slime block reads as safe. The mod is client-side only, so a server does not need it and players can use it on any server. The menu can be opened with a key to adjust the display.
Installation needs Fabric API on Fabric. Fall Damage Predict is published for Fabric only, for Minecraft 1.21.1, under the MIT License, and the code is not open source.
Key features
Landing prediction
The mod works out whether a jump from the current position would end in survival or in death before the player moves.
Visual safety zones
Highlighted zones on the ground show the landing blocks, colored to mark safe and lethal drops.
Water and slime handling
Water and slime blocks are treated automatically, so the indicator shows a safe landing when one is below.
Cached block lookups
Block data is cached so the prediction keeps running smoothly while the player sprints over complex terrain.
Adjustable menu
A menu key opens the settings for the indicator and its display.
