Vertical Navigator
by ffobb
Vertical Navigator previews fall damage and hazards in the block column below the player before a jump, shown on the HUD as hearts and colored markers.
What it does
Sneaking near a ledge makes the mod read the blocks directly beneath the player, so the drop is checked before the player steps off. The estimated fall damage is drawn as hearts, using a height-based formula where each 3 blocks of fall counts as a half heart of damage beyond the safe distance.
Landing in water is shown with a blue marker, since a water buffer cancels fall damage. Lava, fire and the void are flagged with red, orange and purple warnings, marking drops that would be fatal or dangerous. The HUD is configurable: pressing V opens the config screen, and the arrow keys adjust placement.
The mod is client-side only, so a server does not need it installed and players can use it on multiplayer servers. It is released under the MIT License and is not open source. Forge 1.1.0 for 1.20.1 is the only file, published 2026-07-24 and updated 2026-07-25, and the interface switches between English and Chinese along with the Minecraft language.
