Interaction and Feedback

Interaction and Feedback is the layer that makes the world answer the player. A door should feel usable. A loot object should clearly invite interaction. An inspectable prop should communicate that it matters. This category covers the trace, interface, outline, and feedback patterns that turn static actors into readable gameplay objects.

What This Enables

• Interactable objects that can open, loot, inspect, trigger, harvest, talk, activate, or route into custom gameplay.
• Clear player feedback through outlines, prompts, trace results, and target-specific behavior.
• A consistent bridge between world actors and the systems behind them, without every actor needing a custom input stack.

Working Advice

• First make sure the trace sees the actor. Then check the interface. Then check the feedback.
• Let the interaction system detect and route, but let the target actor own what actually happens.
• Good interaction design is quiet but powerful: the player should understand the world without needing to think about the system underneath it.
