Fx Control!
by McJty
Fx Control! lets server owners attach potion effects and fire to player actions through rule files, so a given block or item can trigger a result under set conditions.
What it does
Rule files decide what happens when a player tries to break or place a block, or left-clicks or right-clicks one. A rule can apply status effects to the player or ignite them, and each rule can depend on conditions such as the dimension, the time of day, the biome, the block the player is standing on, held items or the state of the player. The mod ships five rule files, version 0.1.0, to show how the rules are written.
The mod runs on the server alone, so players join without installing anything. It is published for Forge only, across 10 release versions 1.12.2 – 1.19.3, and the latest Forge file, 1.19-4.0.16, targets 1.19.2. The code is open source under the MIT License, and the author notes say it is compatible with the Lost Cities rules-based building mod. Serene Seasons and Baubles are also named as working with it.
Key features
Break and place rules
A rule can fire when a player tries to break a block or place one, letting the server react to building actions.
Click rules
Left-click and right-click events on blocks can each carry their own rule, so interactions can differ.
Status effects and ignition
Rules can grant a player status effects or ignite them, with the effect chosen in the file.
Condition checks
Conditions cover the dimension, time, biome, the block under the player, held items and other player state.

Use cases
Server-side rules for a modpack
Server owners can add hazards or rewards tied to specific blocks, biomes or times of day without changing client code.
Custom building restrictions
A rule can react when players place certain blocks, for example in a rules-based building setup.
Who it’s for: Server owners and modpack authors who want to script simple player reactions with rule files. Players need nothing installed, since the mod is server-side only.
