Thinner Air
by Penguin_Spy
Thinner Air makes the air in caves, high elevations and the Nether and End hazardous, so players must manage breath to survive those places.
What it does
Air is not always breathable. Deep caves, high elevations and other extreme locations have air that a player cannot breathe safely, and the same applies to parts of the Nether and End. Respirators, which are repaired with charcoal, and Air Bladders, which are refilled with breathable air, let a player carry supplies into those places. Lava and fire make the air immediately around them unbreathable, while Nether and End portals let air pass through them, creating a small bubble of breathable air on the other side.
Thinner Air is a Fabric and Quilt continuation of the original Thin Air project by Fusz, which was discontinued, and it also ports the Miner's Lung idea. It is written with performance in mind and has minor impacts on TPS. Its air quality is data-driven: a datapack or config can define which blocks emit what air quality, and dimension-specific emitters are supported. Only players affected by bad air need to breathe supplies, and the environment is client and server. Installation needs Fabric API and Trinkets Updated; Cloth Config API is optional and Cardinal Components API is bundled inside the mod.
