Inventory System - No-Code RPG Items for Godot 4

Pure-GDScript inventory with drag-drop UI, stacking, weight, hotbar, tooltips, save-ready. Free Lite tier available.

Pure-GDScript inventory for Godot 4.3+. Shared ItemResource, drag-drop UI, stacking, weight, hotbar, tooltips, save-ready. Inspector-first - the canonical "harder than it looks" build, ready. 

Most Godot inventories make you write code for every item. This one makes you write code only when you're shipping a new feature.

**Author items in the Inspector.** Right-click → New Resource → ItemResource. Fill in name, icon, stack size, weight, category, value. Save. Done. Want 50 items? You'll spend more time on art than on setup.

**One inventory data layer, every container type.** `InventoryComponent` handles the player backpack, chests, hotbar, vendor stock, crafting bags, loot containers. Capacity and weight budgets, category filters, accept-partial vs reject-overflow policies - every choice in one Resource.

**UI separated from logic.** Drop an `InventoryUI` in your HUD. Drop a `HotbarUI` at the bottom. Drop another `InventoryUI` for the chest. Each takes the same data layer and re-themes through one `InventoryTheme` Resource - no code to restyle.

**Drag-drop, stack, split, swap, transfer.** Between slots in one inventory, between two open inventories, into the hotbar, out of a chest. Mouse wheel switches hotbar slots. Number keys 1-N activate them.

**Save-ready.** Install [Save / Load](https://itch.io) and every inventory persists automatically - no code, no extra wiring.

**Built for the RPG Toolkit.** The same `ItemResource` is the shared backbone for upcoming Equipment, Loot, Crafting, Vendor, and Quest addons. Buy this; the rest plug in.
