NoFriendlyFire is a client-side Fabric mod for Minecraft 1.21.11 that helps you easily identify players by marking them as friends, enemies, or neutral, and displaying them with colored hitboxes.
- 🟢 Friends → Green
- 🔴 Enemies → Red
- 🟠 Neutral players → Orange
The mod is fully client-only, meaning it does not require installation on the server.
Overview
This mod is designed to improve player awareness in multiplayer environments by providing clear visual distinctions between different types of players.
It is especially useful for:
- PvP servers
- Team-based gameplay
- Survival with friends
- Any situation where quick identification matters
Features
🔹 Player Classification
You can assign players into three categories:
- Friend
- Enemy
- Neutral (default)
Each category has its own color for quick visual recognition.
🔹 Custom Hitboxes
The mod renders custom colored hitboxes around players:
- Color depends on player status
- Slightly thicker than default for visibility
- Stable rendering (no flickering)
- Purely visual (does not affect gameplay mechanics)
🔹 Interactive GUI Menu
A built-in Minecraft-style menu allows you to manage players easily.
Menu includes:
Tabs:
- Friends
- Enemies
Scrollable player list
Buttons to:
- Add player (from crosshair)
- Remove player
- Move between friend/enemy lists
🔹 Nickname Display (Not UUID)
- Internally uses UUID for reliability
