Crusalis FoF (Friend or Foe)

A lightweight, client-side Fabric mod that instantly identifies player allegiances by coloring their hitboxes based on your nation's relationship with them.

What it does

• Relationship Coloring: When you look at a player (with hitboxes enabled via F3+B), their hitbox color changes to reflect their diplomatic status:

  • 🟢 Green - Friendly: Players in your Town, your Nation, or an Allied Nation.
  • 🟠 Orange - Neutral: Players with no specific diplomatic relation or unknown status.
  • 🔴 Red - Enemy: Players belonging to a Nation marked as an Enemy.

  • Intelligent Targeting:

    • Only colors the specific player you are looking at, keeping your screen clean.
    • Uses raytracing to detect targets up to 256 blocks away, perfect for scouting or ranged combat.

  • Reads the Server's Own Tags:

    • Detects each player's relationship straight from their in-game nameplate color. The same red / green / orange the server already shows above their head.
    • Instant and always in sync, with no setup. (Optional: switch to Crusalis Dynmap map data in the config.)

Easy Setup

Works out of the box. Just install and play. No setup required.

• Auto-Detection: The mod automatically identifies your town and nation from the dynmap data on login.
• Live Updates: Relationship data is refreshed every 5 minutes to keep up with changing alliances.
• Smart Retry: If you join before the map API is ready, it keeps checking until it finds you.
• Optional Config: Choose the relationship source (nameplate tags or map data) and set the Dynmap address any time from the in-game settings (via Cloth Config + Mod Menu).

Server Control

Server administrators can disable this mod's features for all connected clients using a chat command if needed for events or balance testing.
