Backpack Mod Summary

What it does

• Adds three backpack items (small 8 slots, medium 18 slots, large 36 slots) that open a storage window when used.
• Right-click/Use with a backpack in an active hotbar/utility/tool slot to open its personal container; contents travel with the item via item metadata.
• Commands: /backpack opens the backpack you are holding, /givebackpack <small|medium|large> gives the matching backpack item to the player.

Implementation notes

• Backpack items are registered dynamically with the Hytale asset store and use item stack containers for per-item storage, so each backpack keeps its own contents even when moved.
• Interaction handling listens for Secondary/Use actions and cancels the event to prevent other default uses while opening the backpack UI.
• Active slot resolution checks hotbar, utility, and tools sections to find the held item before opening its container.

Limitations & suggestions

• Items use the default unknown icon/translation only; add custom textures or localization strings for a polished experience.
• No crafting or loot integration is provided; use commands to obtain backpacks or add recipes as needed.
• Permissions are not enforced; add checks if backpacks should be gated behind ranks or progression.
