Requires the client-side mod “DynamicResourcesMod” for players to be affected.
Install this plugin on the server to send pack-toggle commands, and ensure all participating players have the client mod installed.

Dynamic Resource Pack Controller is a combined server plugin + Fabric client mod that allows server operators to toggle pre-installed resource packs for consenting players during gameplay. It is designed for curated modpacks, immersive events, contextual visual effects, and opt-in prank environments where all players understand the purpose of the system.

Only players who have intentionally installed the client mod are affected.

How It Works

The server plugin communicates with the client mod through the mod’s plugin messaging channel (yourmod:resourcepack), sending simple instructions:

• ENABLE:<pack>

• DISABLE:<pack>

• LIST

The client mod automatically mirrors any folders or zips stored in:

into the normal resourcepacks/ directory and registers them.
This enables dynamic toggling of curated visual layers such as phase effects, alerts, ambience changes, or friendly pranks (used responsibly).

Installation

Server

into your server’s plugins/ directory.

They will automatically be copied into resourcepacks/ for toggling.

Consent & Appropriate Use

This system must be used only with players who have intentionally installed the client mod and understand its behavior.
Use of this tool should always be transparent, consensual, and non-malicious.

Players should know that installing the mod means the server may toggle pre-included resource packs during gameplay.
Do not use this tool to mislead, harm, or distress players.

Performance Notice
