Sanity Level
by kyonshi0104
Sanity Level adds a sanity meter to Fabric worlds, so time spent in dark or hostile places has visible effects on the player.
What it does
Sanity Level introduces a sanity value to Minecraft. Staying in dark areas, or in dimensions and biomes near monsters, lowers it. Staying in peaceful biomes, such as plains under sunlight, or near tamed dogs and cats, lets it recover. When sanity drops, the screen shows monochrome shaders and noise, and the player hears ghostly sounds. Low sanity can also make the player drop items involuntarily, and if sanity reaches 0 the player takes continuous damage.
A Strange Potion is added, brewed with glowstone and extended with redstone, for players who want a way to change their sanity. Settings can be adjusted in-game, and the mod works with Mod Menu. Every player and the server need a copy of the mod. Builds target Minecraft 1.21 – 1.21.11 on Fabric, with a latest file for 1.21.11, and the code is released under the MIT License, so it is open source.
