Don't Forget To Breath
by Hasi
Don't Forget To Breath adds a breath mechanic that keeps players aware of their air supply, with lung capacity that players can build up over time.
What it does
The mod turns breathing into a constant challenge. Players hold breath with the R key, and a timer tracks how long they can stay underwater or in other air-poor places. Breathing stays active at all times rather than switching on only in certain areas, which keeps the challenge present throughout play. Sprinting is the one action that stops automatic breathing from working, so a player who sprints while submerged still has to watch the air meter.
Lung capacity is set at five levels, and a player's capacity affects how long a single breath lasts. Players can also stop holding a breath deliberately, which lets them end a long hold early. Air is restored through a mask item, and masks are defined through a common air-mask tag, so modded masks can be added to the same system. The mod is built for NeoForge 1.21.8 and runs on client and server, so the server and every player need it. It is published under All rights reserved and is not open source.
Key features
Constant breath challenge
Breathing is always active, so the air supply remains a challenge during normal play.
Automatic breathing
Breath is restored without manual input, except while the player is sprinting.
Hold and release control
Players hold a breath with the R key and can stop holding it before the timer runs out.
Five lung-capacity levels
Lung capacity has five levels, and it sets how long each breath lasts.
Air masks by tag
Masks are registered through the air-mask tag, so other mods can add items that supply air.
