ManaBarLib
by MinoBanana
ManaBarLib is a Forge library for 1.20.1 that lets modders add and configure mana bars, and lets server owners control them with commands and NBT tags.
What it does
Mod authors can define their own mana bars through configuration instead of writing the bar logic from scratch. Bar locations can be set, and the library tracks each bar's value and cooldown for every player. Cooldown rates are applied per player, not as one shared rate for the whole server.
The bar is controlled through NBT tags and through a set of addition commands, so values can be changed in game or from a command block. The cooldown setting accepts decimal values, and the displayed result is capped at 100%, so a bar reading above 100.9% is shown as full. Client and server both need the library, so the bar and its values stay in sync between the two sides.
Key features
Configurable mana bars
Modders can declare mana bars through configuration, with their own names and settings.
Per-player cooldowns
Cooldown rates are applied to each player individually, so one player's recharge does not change another's.
Decimal cooldown values
The cooldown setting accepts decimal values, and the result is capped at 100% when it would exceed it.
Command and NBT control
Bar values are changed through NBT tags and addition commands, with a list of useful commands documented by the author.

Use cases
Adding mana to a Forge mod
A modder who wants a mana resource for spells or abilities can declare the bar in configuration rather than building it by hand.
Tuning a server
Server owners can adjust cooldown behavior and bar values with commands, without editing the mod that uses the bar.
Who it’s for: Modders building magic or ability systems on Forge 1.20.1, and server owners who want to change mana values with commands.
How it compares
Iron's Botany is open source under the GNU General Public License v3.0 or later, for Forge 1.20.1 with client and server environments, and it is a botany mod rather than a mana library. Lightning Abilities is also a Forge 1.20.1 mod for client and server, but it is released under the MIT License and is not open source. DALeveling - Solo Leveling Mod is client-side only, so servers run without it, and it is not open source. ManaBarLib is the only one here that is a library for building mana bars rather than a finished gameplay mod.
