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

Note: Commands require OP rights. OPs can grant permissions to other players using /fakeplayer permission grant <player>.

1. Add a chunkloader: Type /fakeplayer add (or /fp add) in chat at the location where you want to keep chunks loaded
2. Open menu: Right-click on the fakeplayer to open the interactive menu
3. Disable a chunkloader: Attack the fakeplayer (left-click) to disable it. It will be moved to the disabled chunkloaders list (accessible via F8)
4. Remove a chunkloader: Sneak and attack (or sneak and right-click) the fakeplayer to permanently remove it, or use /fakeplayer remove <name>
5. All information: Click the Info button in the menu to access all mod information, features, and details
6. Commands: Under the Info button, you'll find a Commands button with a complete list of all available commands

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
