About this Mod
F3 Remover
F3 Remover is a simple yet effective Fabric mod designed to restrict the usage of the F3 debug screen.
✨ Features
Client-Side
- Blocks F3: Pressing F3 normally shows debug info (coordinates, facing direction, etc.). This mod intercepts that and hides it completely.
- Custom Message: Instead of debug info, players see a large red warning: "This Server does not like that you are trying to do that".
- Credit Link: A direct link to the creator's profile is displayed on-screen.
Server-Side
- Install on Server (Optional): You can install this jar on your dedicated server.
- Automatic Detection: If a player joins the server without having this mod installed, the server will detect it and send them a chat warning prompting them to download it.
- Fair Play: Helps encourage players to play without debug advantages.
📦 Improvements
- Universal Jar: One file for both Client and Server.
- Safe: Won't crash your server; client-only code is properly separated.
