Carpet
by altrisi
Carpet adds a set of technical rules and debugging tools to vanilla Minecraft, and most of them are configured on the server.
What it does
Carpet exposes many individual game settings that can be changed while the game runs, covering technical behavior such as tick timing, mob spawning and block updates. A full list of these settings is kept on the mod's wiki. The mod also includes commands that report server performance, such as the mob cap and ticks per second, and these values refresh live in the chat log.
Scarpet is a programming language built into Carpet. It lets server owners and players run scripts that interact with the world, and Carpet includes a few built-in scripts that can be loaded at any time. Other scripts are kept in the Scarpet repository, and the mod's docs explain how to write new ones. Carpet also has many extension mods that add further rules and functions.
Only the server needs to run Carpet, and players may leave it out. It is published for Fabric across 43 game versions, 1.14.4 – 26.3, with snapshot builds also available, and the source is released under the MIT License as open source. Carpet-Fixes, GugleCarpetAddition, Carpet TIS Addition, Carpet Extra and Carpet Org Addition are among the 93 mods that require it.
