Mind Your Bubbles
by Quyet
Mind Bubbles changes how the vanilla air bar is drawn underwater, making the bubble count easier to read on the Fabric client.
What it does
The client-side Fabric mod reads the air value that Minecraft already stores for the player and presents it more clearly than the standard HUD, which shows only a few bubbles. A player can pick how the bar appears: the vanilla display, a full bar that is always visible, or a bar that hides itself when air is full. The default is the vanilla display, and the mod is enabled by default.
Smoothing is the main difference from the vanilla bar. When air changes in large or small steps, the transitions between bubbles are animated so missing bubbles fill in gradually and the bar stays readable. Custom air-drain displays from other mods can be kept stable in non-vanilla scenarios. Options are kept in a generated file inside the config folder of the game instance.
Installation needs Fabric Loader, Java 21 or newer and a Minecraft version that matches the file being installed. Mod Menu and Cloth Config API are required dependencies, and they provide the settings screen. The mod is client-side only, so servers do not need it, and it is published for 1.21.1 – 1.21.11 with the latest file for 1.21.11. The code is open source under the CC0 1.0 Universal license.
