Custom Message Blocker
The mod included in this project is a little mod I've been working on that adds the ability to not show certain chat messages. They can be messages which contain a word you don't want to see, or an EXACT word you don't want to see.
Quick answer
Which Custom Message Blocker release should I use?
Custom Message Blocker 1.0.0 targets 1.21, 1.21.1, 1.21.2 with Fabric. It must be installed on the client. Do not install it on the dedicated server. All 1 required mods have matching files.
Where it goes
Is Custom Message Blocker required on the client, server, or both?
It must be installed on the client. Do not install it on the dedicated server.
This file is marked client-only.
What else does Custom Message Blocker 1.0.0 need?
1.0.0. Change the file and its required mods may change too.
Install Fabric API first. We found matching files for this game-version and loader setup.
We only count dependency files that match this setup. A file for another loader does not fill the gap.
