The **Inventory Manager (AC\_InventoryManager)** provides all the necessary functionality to handle player Inventory & Storage, including adding, removing, and using items, managing currency, and updating the UI in runtime.
It is added to the **PlayerController** class by default **(PC\_SoulslikeFramework).**
### **How It Works**
1. **Initialization**:
* Initializes all item slots and prepares the inventory UI for use.
* `InitializeLoadedInventory` method tries to load inventory data from the relevant save slot.
2. **Item Handling**:
* **Adding Items**: Items can be added through the relevant item asset or a Gameplay Tag.
* Automatically increments quantity if the item already exists, or creates a new slot if it doesn’t.
* **Removing Items**: Removes a specific quantity or deletes the item from the inventory entirely.
* **Using Items**: Triggers the item’s `OnUse` function, spawning the appropriate actor (e.g., potion, consumable) and applying effects.
* **Triggering Actions:** Triggers the item's provided `ActionTag`, queueing it through the Input Buffer.
3. **Inventory Queries**:
* Supports multiple ways to query inventory data:
* **HasItem**: Checks if a specific item is present.
* **GetAmountOfItemWithTag**: Retrieves the quantity of items matching a specific tag.
* **GetEmptySlot**: Finds the next available empty inventory slot.
4. **UI Updates**:
* Event dispatchers such as `OnInventoryUpdated` and `OnCurrencyUpdated` ensure the inventory UI is always in sync with changes.
* The `GetInventoryWidget` function links the UI directly to the inventory component.
5. **Saving/Loading**:
* The `SaveAllInventory` function serializes the inventory state, including items, quantities, and configurations.
* Inventory data is restored on load using the `InitializeLoadedInventory` function.
### Example Usages
The provided **Parent Door Class (B\_Door)** has a great example on utilizing the Inventory Manager for checking if **multiple key items** (e.g, KeyA x1 & KeyB x4) exist in inventory before unlocking a door:
Rest of the functionality is mainly handled by **Inventory Widget.**
