deicore
deicore lets server owners and players store named integer values in the world, read them with commands and change them from the command line or from other mods through its API.
What it does
Installed on Fabric for Minecraft 1.21 and 1.21.1, deicore adds a /worldvar command family. A variable is created with an integer starting value, and it persists across the whole game in the same way a scoreboard does. Commands can query a variable, set it to a new value or add to it, and each action reports a result message.
Error handling is part of the command output. A variable that does not exist, a value that cannot be read as an integer, or an unexpected failure each produce a separate message. Failed queries return 0. The mod also exposes functions to other mods through a documented API, and the author points to a configuration manager mod for settings beyond the commands.
The mod is published for Fabric only, for Minecraft 1.21 and 1.21.1, with 1.0.0 for 1.21.1 as the latest build. Its source code is licensed under the GNU Lesser General Public License v3.0 or later, which makes deicore open source.
Key features
Persistent integer variables
Named integer variables are created with an initial value and stay available for the whole game.
Set, query and add commands
Commands read a variable, assign it a new integer or add a value to it, returning the updated result.
Result messages
Each command reports success, a missing variable, a format error or an unknown error with a specific message.
Failure fallback
A query that fails returns 0, so scripts and command blocks can continue without stopping.
Developer API
Other mods can call the same variable functions through the API that deicore provides.

How it compares
QisMoreCommands is server-side only, open source under the MIT License and published for 1.21.1, so players join without installing it. VariableMod is client-side only, open source under the MIT License and covers 1.21 – 1.21.8, so it changes what a player sees rather than the server.
