Why use it
- One controller orchestrates detection (overlap and raycast), input, UI prompts, selection and highlighting, and simple animations.
- Clean editor flow: focused custom inspector per type, plus a bulk‑add window.
- Look‑to‑interact option and “auto start/stop” when NeedInteraction is disabled.
- Placement previews and “out‑of‑range” indicators built in.
- UnityEvents on Interactable let you hook gameplay without writing code.
What’s included
- Core runtime: Interactable, InteractionController, InteractionType and Exclusivity
- Editor tooling: custom inspector and Interactable window
- URP outline material for selection highlights
- Minimal demo scene and prefabs for every interaction type
- DOCUMENTATION.pdf (setup, tips, and notes)
How it works (runtime highlights)
- Periodic sphere overlap collects nearby colliders; per‑frame selection with optional camera‑based look targeting.
- Doors, buttons, and switches animate via coroutines. Levers and wheels expose angle and percentage, with clamp or free‑spin modes.
- Holding: mouse wheel adjusts distance; right mouse plus move rotates held items; drop key restores physics.
- Exclusivity: world‑lock or type‑lock prevents conflicting interactions.
Limitations
- Single‑player only (no networking).
- Uses Unity’s classic Input by default (New Input System not integrated, update coming soon).
- URP outline material included; Built‑in/HDRP users should supply a compatible outline or disable highlight, updates for HDRP and Built-In shaders soon.
- Demo controller uses a Unity 6 API; see Compatibility.
