InvScale

Overview

InvScale is a modpack utility that limits how much inventory space players can use. It works by filling certain slots with a special "locked" item that can't be moved, dropped, or used - effectively shrinking the player's available inventory.

Features

• Restricts player inventory by locking slots from the bottom-right
• Locked slots are filled with an unmovable barrier item
• Works in Survival and Adventure mode only
• Creative and Spectator players are unaffected
• Fully configurable - choose how many slots to lock (0-36)
• Barrier items don't drop on death and don't clutter the world

How to Use

1. Install the mod on your server (this is a server-side mod)
2. Edit the config file invscale-server.toml in your server's config folder
3. Set lockedSlots to the number of slots you want to lock (default: 27)
4. Restart the server or reload the config
5. Players in Survival or Adventure mode will have their restricted slots filled with barrier items

Tips & Tricks

• Default setting locks 27 slots (3 rows), leaving 9 hotbar slots free
• Setting to 0 disables the restriction entirely
• Setting to 36 locks all inventory and hotbar slots
• Players can still use their armor and offhand slots normally
• Great for challenge maps or limiting hoarding in survival servers

Known Limitations

• This is a server-side mod only - vanilla clients can still connect
• The restriction applies to main inventory and hotbar only, not armor or offhand
• Some advanced inventory interactions may briefly show before being corrected
