# Builder Exploration Notes — Task 4: Click To Toggle Visual State

## Capability Gap Identified

- **Click Interaction Behavior**:
  - `onClick` trigger is available in the UI, but did not produce visible state changes during testing
  - Interaction execution appears inconsistent or unclear

- **State Management**:
  - No visible support for defining or managing state variables (e.g., boolean toggle)
  - No clear mechanism to store or switch between visual states

- **Visual State Transition**:
  - Unable to toggle between two visual states (e.g., color change)
  - Object remains in default appearance despite interaction attempts

---

## Observations

- Interaction system UI is present but lacks clear connection between events and property updates
- No built-in concept of "state" for managing toggles
- Event-to-property binding is not intuitive or not functioning as expected

---

## Comparison vs Code

- **Vanilla**:
  - Requires raycasting + manual state handling
  - Fully flexible but verbose

- **R3F**:
  - Simple toggle using `onClick` + `useState`
  - Very clean and reliable

- **Thob**:
  - Click interaction present in UI
  - Toggle behavior could not be achieved during testing

---

## Key Insight

The builder currently lacks a clear state management system and reliable event-to-property binding, making it difficult to implement toggle-based interactions.

---

## Product Perspective

Toggle interactions are essential for use cases like product configurators (e.g., switching colors, enabling features). Without reliable state handling, these use cases are difficult to implement.

---

## Improvement Recommendations

1. **State Management UI**  
   - Introduce simple state variables (e.g., `isActive`, `isSelected`)

2. **Property Binding System**  
   - Allow material properties (color, visibility, etc.) to be linked to state variables

3. **Reliable Event Execution**  
   - Ensure `onClick` triggers consistently update state and reflect changes in the UI

---

## Verdict

Strong for **static visual configuration**  
Limited for **state-driven interactions (toggle, dynamic behavior)**
