Interaction

Interaction is a full interactive component that lets you interact with actors in the world. From starting dialogue to opening chests.

Interactables are components that you add to actors to give interactable functionality.

For example, if you add the interactable, Interactable_ItemPickup that actor will now allow you to pick up an item.

The Interaction component is the driver that checks for all Interactables.

Activate / Deactivate

It is common to disable and enable an interaction component depending on your games state. For example a character during a cutscene will not want to interact with anything.

This can easily be toggled using Unreal's built in Activate and Deactivate events..

Changing keys

By default, Narrative Interaction is set up to use the Gamepad Face Button Left (Square / X) or the E key. You can easily change these to match your exact requirements.

Inside the NarrativeCommonUI plugin folder there is a CommonUIInputAction asset called DT_NarrativeInputActions.

Open this up and find the name of the key you wish to change. In this case, the Interact row name is going to handle the interact option. Select it and you can set the keyboard and gamepad input types.
