ParallaxLib
ParallaxLib is a Forge library from Parallax Studios that gives other mod creators shared code for potion effects and player data.
What it does
A developer who writes a Forge mod can call ParallaxLib instead of writing the same helper code again. Its central utility, PotionHandler, applies potion effects to entities by name. Effect names are matched case-insensitively, so speed, fire resistance and haste all resolve without the caller touching a raw MobEffect object. A registry is built automatically when the class loads and maps each registered effect name to its instance.
The library also handles lists: it can apply a set of MobEffectInstances to an entity in one call, and it can get the effect of an entity by its string name. If an effect name cannot be matched, the error is printed to the console. ParallaxLib stores player statistics such as health, food, potion state and inventory quick access, so other mods can read them from one place.
Installation requires Forge. A server running it needs every connecting player to have it too. Files are published for Forge only, for Minecraft 1.19.2, with 25.5.19 as the latest file. The code is released under All rights reserved, so it is not open source.
Key features
Potion effects by name
PotionHandler applies an effect to an entity from a plain string, with names matched regardless of letter case.
Effect registry
A map from registered effect names to their MobEffect instances is built once, when the class loads.
Batch effect application
A list of MobEffectInstances can be applied to an entity in one call, including ones that are already prepared.
Shared player data
Health, food, potion and inventory quick-access stats are kept in one store that other Parallax Studios mods can use.

Effect-based gameplay
Mods that buff or debuff players can apply effects by name, which keeps configuration files readable.
Who it’s for: Forge mod developers targeting 1.19.2 who want shared helpers for potion effects and player statistics, and server owners whose installed mods depend on it.
