MapSwitch

MapSwitch is a Fabric server mod for multi-world gameplay with strict per-map player-data separation.

What It Does

• Switch players between maps with:
  • /mapswitch <map>
  • /map switch <map>
• Keeps map-specific player data isolated:
  • inventory
  • XP / health / hunger
  • ender chest
  • stats
  • advancements
• Supports map-based tab-list separation.
• Shows active map hints in actionbar.

Folder Layout

• Maps are read from the server root:
  • ./maps/<map>/

Expected per-map folders:

• playerdata/
• stats/
• advancements/
• DIM-1/ (nether source)
• DIM1/ (end source)
• optional overworld region/, entities/, poi/

Notes

• Built for Fabric + Minecraft 1.21.11.
• Server-side focused mod.
