The **AI Interaction Manager (AC\_AI\_InteractionManager)** is responsible for handling NPC interactions, primarily focusing on **dialogue and vendor** logic. It determines **which dialogue should be displayed based on the player's progress** and displays the associated dialog entry upon interaction. Additionally, it allows NPCs to function as vendors, providing a seamless transition from dialogue into a shop or trade interface.
It is added to the **Soulslike NPC (B\_Soulslike\_NPC)** class by default.
### **How it Works**
* **Dialogue Handling**
* Upon interaction with an NPC, the `BeginDialog` method is triggered. It ensures that a reference to the player's **Progress Manager** and the NPC’s **Dialog Asset** is valid before proceeding.
* It fetches the appropriate **Dialog Table** based on the player’s progress and resets the **dialog index** to 0.
* The dialog index is adjusted accordingly, either moving to the next line or exiting the conversation.
* If the player **exits mid-dialog**, the system ensures that the dialog index is adjusted appropriately *(so that entries that execute gameplay events cannot be re-triggered).*
* **Executing Gameplay Events**
* If the current dialog entry has an **event**, it triggers it via[ **AC\_ProgressManager**](/components-managers/player-specific-components/progress-manager.md) **-> ExecuteGameplayEvent()**.
* **Vendor Handling**
* Upon completing the **last dialog entry**, the system checks if the NPC has an associated **vendor asset**.
* If a vendor asset is found, the **NPC Window** is set up, transitioning the player into the vendor/shop interface.
* If no vendor asset is present, the conversation simply ends.
