Start Quest Or Dialogue

Type: Requires external gameplay system

This example uses a complete quest-board actor and routes the interaction into your own quest or dialogue framework.

External dependency note

Quest and dialogue logic are not part of EDInteractionSystem. The plugin only provides the validated interaction trigger and context.
