About this Mod
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 128 blocks away, perfect for scouting or ranged combat.
Automatic Data Sync:
- Fetches live data directly from the Crusalis Dynmap API.
- No manual configuration needed—it automatically detects who you are and who everyone else is.
Zero Configuration
No menus to config. Just install and play.
- 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.
