Introduction to Interactables #

In AAMS, the BP_BaseInteractable serves as the foundational parent actor for all non-AAMS specific interactable actors. This includes a wide range of entities such as doors, movable platforms, teleports, buttons, and newly introduced pickup items. The Base Interactable integrates seamlessly with the AC_Interact_AAMS actor component, facilitating dynamic interactions within the game environment.

Functionality Overview:

  • Interaction Initiation: When a player enters the Interaction Collision area of an interactable, the AC_Interact_AAMS component is notified, signaling that an interaction is possible.
  • Interaction Execution: Upon the player pressing the interact key, the component executes a trace to identify the interact mesh, triggering the Initiate Interact BPI event in BP_BaseInteractable. This event subsequently activates the Begin Interact event, which is essential for managing interactions across all child actors derived from BP_BaseInteractable.

Setting Up a New Interact Actor #

Steps to Create and Configure:

  1. Create a Child Actor:
    • Derive a new actor from BP_BaseInteractable. Open your newly created child actor.
  2. Configure Mesh and Collision:
    • Assign your interactive object mesh.
    • Adjust the InteractionCollision to appropriately fit around your object, ensuring it covers the necessary interaction area.
  3. Define Interaction Events:
    • In the Event Graph, add the Event Begin Interact.
    • Utilize this event to define the specific interactions, such as movements or state changes, that occur when the interact key is pressed.
  4. Adjust Interaction Settings:
    • Interaction Action: Describes the action performed (e.g., ‘Open’ for a door).
    • Actor Name: Identifies the actor (e.g., ‘Door’, ‘Button’).
    • In Volume Interaction: Triggers interaction upon entry into the InteractionCollision if set to true.
    • Only Use Once: Disables further interactions after the first use.
    • Is Used: Manually indicate if the object has been interacted with, useful for game state management and saves.
    • Show Widget: Controls the display of the interaction widget, which can be hidden when In Volume Interaction is active.
    • Tags: Define specific actor tags required for initiating the interaction (e.g., ‘Player’).
  5. Character Animation Integration:
    • For detailed instructions on syncing character animations with object interactions, refer to the Interaction Component section of the documentation.
