Fakeplayer Chunkloader (Minecraft 1.21.10 & 1.21.11)

A Minecraft mod that keeps chunks loaded with fake players while providing live HUDs and map controls for monitoring without relying on real players. Available for Fabric, Forge, and NeoForge.

Highlights

Dual mode: Fakeplayer (mob spawning + simulation distance) or Chunkplayer (chunk tickets only)
Visual markers & HUDs: Color-coded markers, live Simulation/Chunkplayer HUDs, and interactive chunk map
Interactive map: Terrain-rendered chunk map with controls for toggling, radius adjustments, and mode switch
Resilient config: Per-world JSON file with backups, limits, and auto-restoration

How to Use

Open menu: Right-click on the fakeplayer to open the interactive menu
Disable a chunkloader: Attack the fakeplayer (left-click) to disable it. It will be moved to the disabled chunkloaders list (accessible via F8)
Remove a chunkloader: Sneak and attack (or sneak and right-click) the fakeplayer to permanently remove it, or use /fakeplayer remove <name>

Configuration

The mod automatically creates and manages a configuration file at <world-directory>/chunkloader_config.json. All settings can be changed via commands or the interactive map.

Automatic features:

Configuration is created automatically when you add your first chunkloader
Up to 5 backup files are created automatically (timestamped)
Corrupted configs are automatically restored from backups
Each world dimension has its own independent configuration

Important Notes

Fakeplayers never break blocks or use items
Name lookups are case-insensitive and suggest alternatives if a name isn't found
The system prevents overlapping chunkloaders and warns when positions conflict
Works across Overworld, Nether, and End dimensions
Default radius/simulation distance is 0 (1 chunk) for new chunkloaders
Chunkloaders can only be disabled/removed by players, not by mobs
