Feature: Add Vehicle Movement Controls Using WASD/Arrow Keys with Realistic Wheel Rotation & Physics

✨ Description

Incorporating interactive controls that enable users to drive a vehicle model using either the WASD keys or arrow keys is a crucial aspect of creating an immersive experience in a landing scene. This feature should simulate basic car-like movement, including forward/backward driving and left/right turning, while realistically rotating the wheels and steering based on the direction. By implementing this feature, we can lay the foundation for future mobility-based interactions and enhance the overall user experience.

📋 Requirements

To achieve this feature, we need to meet the following requirements:

  • Enable movement using both WASD and ↑ ↓ ← → keys: The user should be able to control the vehicle's movement using either the WASD keys or the arrow keys.
  • Simulate real-world physics (acceleration, deceleration, basic momentum): The vehicle's movement should be simulated using real-world physics, including acceleration, deceleration, and basic momentum.
  • Rotate wheels as the car moves: The wheels of the vehicle should rotate realistically as the car moves.
  • Animate front wheels for steering: The front wheels of the vehicle should animate to indicate steering.
  • Maintain smooth camera tracking (if applicable): The camera should track the vehicle smoothly during movement.
  • Ensure compatibility with existing scene layout and object setup: The feature should be compatible with the existing scene layout and object setup.

📋 Acceptance Criteria

To ensure that the feature meets the requirements, we need to meet the following acceptance criteria:

  • Pressing W/↑ moves the car forward with rolling wheel animation: The car should move forward when the W key or ↑ key is pressed, with a rolling wheel animation.
  • Pressing S/↓ moves it backward (optional: reduced speed): The car should move backward when the S key or ↓ key is pressed, with an optional reduced speed.
  • Pressing A/← and D/→ turns the vehicle left/right, rotating front wheels: The vehicle should turn left or right when the A key or ← key is pressed, and the front wheels should rotate accordingly.
  • Movement respects scene boundaries (no driving through the void): The vehicle should not be able to drive through the void or outside the scene boundaries.
  • No performance drops during movement: The feature should not cause any performance drops during movement.
  • Works on both desktop and mobile (optional touch support for future): The feature should work on both desktop and mobile devices, with optional touch support for future development.

🧩 Sub-Issues / Tasks

To implement the feature, we need to break it down into smaller sub-issues and tasks:

  1. feature/vehicle-controls-keyboard
    • Add basic keypress listeners: Add listeners to detect key presses and releases.
    • Implement directional movement logic: Implement the logic for directional movement, including forward, backward, left, and right movement.
    • Integrate basic physics (inertia, speed cap, etc.): Integrate basic physics to simulate real-world movement, including inertia and speed caps.
    • Animate wheel rotation synced to movement: Animate the wheel rotation to match the movement of the vehicle.
    • Add visual steering to front wheels: Add visual steering to the front wheels to indicate steering.
    • Debug and test edge cases (stuck, out of bounds, etc.): Debug and test the feature to ensure that it works correctly in edge cases, such as stuck or out-of-bounds movement.
  2. feature/vehicle-controls-mobile (optional, future)
    • Add on-screen joystick/buttons: Add an on-screen joystick or buttons to control the vehicle on mobile devices.
    • Responsive control overlay: Create a responsive control overlay that adapts to different screen sizes and orientations.

📎 Additional Context

When implementing the feature, we might want to consider using libraries like cannon-es, three.js, or use-cannon for physics handling. These libraries can help us simulate real-world physics and create a more realistic experience.
