ConditionMod

ConditionsMod creates events from YAML configuration. Each event follows a condition-action workflow: it detects that something has happened in the game, checks whether the requirements are met, and runs its result actions only when the conditions pass. Events are declared in a root section and can use list formats, text conditions such as a command or chat match, and compound conditions joined with or. Conditional action branches let an event choose between different actions with execute.

The mod takes its inspiration from ConditionalEvents and targets a leaner, faster and more adaptable setup for modern servers. ConditionsMod keeps the familiar event, condition and action layout, and its ConditionalEvents-style configuration lets server owners migrate many existing setups without rewriting them. Conditions support common operators.

The mod is published for Fabric and Forge, across 1.20.1, 1.20.4 and 1.21.1. Players need it on their client, while the server can add it for extra features and runs fine without it. Its license is All rights reserved, so the code is not open source. Some setups need coding for advanced events, though the basic configuration does not.
