Eureka Effect
by hehemancer
Eureka Effect is a Fabric server mod that lets operators trigger game events from a command.
What it does
Eureka Effect runs entirely on the server, so only the server needs it and players join without installing anything. Its command can invoke several categories of game events, including GameEvents, LevelEvents and EntityEvents, and it can also change internal player data. The author built it for debugging, and the notes advise using it carefully and only with a clear understanding of what each action does. Files cover 1.20.1 and 1.21.9, the latest being 1.0.0 for 1.21.9, released under the MIT License and not open source.
