Smart warnings
Smart Warnings is a Fabric, Forge and NeoForge utility that sends short survival alerts when night falls, when the inventory is nearly full and when hostile mobs are close.
What it does
Players get a short actionbar message when night starts, reminding them to find a bed before danger rises. A second warning appears when free inventory space runs low, so loot is less likely to be lost on long mining trips or exploration runs. A third alert flags hostile mobs that come near the player.
The alerts are meant to stay out of the way: the HUD gets no extra panels, and the messages are brief and sit on the actionbar line. The mod is client and server, so both the server and every player need it. It works in multiplayer, and the author notes it has no effect on vanilla gameplay beyond these warnings.
Files are published for Fabric, Forge and NeoForge across five release versions, 1.20.1 – 1.21.11. The Fabric build targets 1.21.11 and the NeoForge build targets 1.21.8. The code is not open source and is released as All rights reserved. The author has listed further warning systems as planned for later updates, but none of them are in the current files.
