Skill: Interactables (3D)

Objective

Provide a consistent interaction system for:

• NPC conversations
• signs/plaques
• containers that give items once

Recommended pattern

• Player owns an InteractionDetector (Area3D) that tracks nearby interactables.
• Interactables join group: interactable
• Interactables implement an API (interface-by-convention):
  • get_prompt() -> String
  • interact(actor: Node) -> void

Steps

1. Create a reusable base script

• game/scripts/exploration/interactable.gd (class_name Interactable)

2. Create interactable scenes

• game/scenes/actors/NPC.tscn
• game/scenes/props/Sign.tscn
• game/scenes/props/Container.tscn

3. Player selection

• On interact action:
  • select nearest interactable in range
  • call interact(self)

Verification

• NPC: shows dialogue and closes cleanly.
• Sign: shows text and closes cleanly.
• Container: adds item and becomes empty after first open.
