NeoBackSlot

NeoBackSlot

NeoBackSlot is a lightweight Back Slot and Belt Slot equipment mod for NeoForge 1.21.1.

Store weapons and tools on your character's back or belt for quick access using configurable keybinds (by default G for the Back Slot and V for the Belt Slot). Items are fully synchronized in multiplayer and visible to other players.

NeoBackSlot is designed with compatibility in mind, supporting not only vanilla equipment but also many modded weapons and tools, making it a great fit for heavily modded RPG-style modpacks.

Credits

NeoBackSlot is heavily inspired by the original BackSlot mod created by Globox1997.

This is not a direct port of BackSlot. NeoBackSlot is an independent NeoForge implementation developed specifically for Minecraft 1.21.1.

Compatibility

NeoBackSlot has been successfully tested with:

• Singleplayer
• Dedicated servers
• Multiplayer environments
• Large modpacks (300+ mods)
• YIGD (You're In Grave Danger)

The mod is designed to work alongside most NeoForge modpacks without requiring additional libraries.

Known Issues

• Tridents may appear visually misaligned when equipped in the Belt Slot.
• Some modded shields may require additional transform or scaling adjustments.
• Grave mods restore Back Slot and Belt Slot items as regular inventory items.
• If a grave is claimed while the player's inventory is completely full, Back Slot and Belt Slot items may not be restored correctly.
