Interaction Interfaces
The basic functionality of the Interactable Component and the way other systems interact with it, can be modified using additional BP Interfaces that can be implemented on your interactable BPs.
Interactable Options Interface
Adding an M2 Interactable Options Interface to your object allows fine-tuning specific interaction behaviours through various optional interface functions, explained below.
| Should Single Option Bypass Menu
By default, if there is only one interaction option on an interactable, it will instantly trigger this option instead of opening the list when interacted with. สc
This function allows overriding this functionality on a per-option basis.
Example use: an object where you always want a prompt before confirmation, ie. a vending machine with a varying amount of options.
|
| Should Close Menu on Option Select
By default, the interaction list will stay on-screen after selecting an option. สc
This function allows overriding this functionality on a per-option basis.
|
| Get No Options Available Text
Allows displaying prompt text when there are no interaction options available.
|
| Get Interaction Option Display Details
Allows dynamically specifying the display name for individual options without changing them
|
| Get Interaction Enabled State
Allows dynamically making interaction options disabled/hidden, optionally using the provided Interaction Instigator.
Example use: locking or hiding a certain interactable/option from unauthorized players

Interaction Point Override
When using Approachability to click on interactables and automatically navigate to and interact with them, the location the character walks to is picked based on physics traces and pathfinding around the interactable. With BPI Interaction Point Override, we can manually specify where the character should navigate to in order to interact with our object.
This can for example be used to make a character always approach an interactable the same way (ie. Seat) or make an object interactable from anywhere, incl. beyond interaction range (ie. Screen focus).
| Get Interaction Point
Tells Approachability Movement where to navigate the character to interact with this object. Player Character is the character trying to navigate. Interaction Point is our location override. When set to the character's current location, the character won't move but will interact on the spot. Success can be set to true to apply the location override, or false to revert to the default behavior
