Lava Alert
by 3geE
Lava Alert warns a player when lava lies beneath them, using a visual cue and a sound effect so that accidental falls are less likely.
What it does
The mod is a datapack that checks the blocks under each player. When lava is detected below, a message appears on screen together with a sound. Each player can switch the warning on or off individually, with commands to enable or disable alerts for their own character. Coordinates are shown along the bottom of the screen while moving, so the position of nearby lava can be read at a glance.
The datapack works in singleplayer and multiplayer. It is installed by placing the file in the world's datapacks folder, after which the world is reloaded once the player has joined. Server owners need it on the server side, while players only need the client to receive the visual and sound alerts. Because it is a datapack, it is published for the Data pack platform and needs no mod loader. Files cover 1.21 – 26.3 across Fabric, Forge, NeoForge and Quilt, with 1.1 for 26.3 as the latest file on each loader, released 2025-08-20. The mod is first published 2025-06-19 and is released under All rights reserved, so it is not open source.
