VR Avionics Simulations

Project Overview

• Each functionality has it's own MonoBehaviour component following the Composition Programming Pattern.
• Inter-Script communication is done via public Inspector references for maximum code optimisation.
• Scene Hierarchy is clean (without unnecesary, unused objects) and objects are named properly.
• Maximum things are done via scripts and thus very limited editor/inspector dependency.

Thus, the above ensures butter-smooth, error-free scalibility and maintainability.

Creative/Innovative Solutions

• Hand and Controller tracked Control UI (this keeps UI accessable even when camera view changes)
• Modern aesthetic UI
• UI tooltips for each mechanism in the scene
• Use of joints to limit movement for switches and levers
• UI Audio feedback

Design Decisions, Implementation Details, and Challenges Faced

1. Detecting Lever/Switch Fully Moved to On/Off Position

• Challenge: Unable to use Update() to track rotation due to performance concerns.
• Solution: Used triggers to detect when the lever or switch reached the desired position.

2. On/Off Triggers Implementation

• Challenge: Rigidbody with hinge handles was not working correctly.
• Initial Consideration: Using on/off colliders as trigger detectors, but this introduced redundancy and dispersed logic.
• Final Solution: Created a child GameObject of the handle with a Rigidbody, allowing a singular and cleaner implementation.

3. Handling VR Movement During Camera View Switch

• Challenge: The user can move around in VR, which affects switching between different camera views.
• Solution: Assuming a seated experience, locomotion is turned off, and camera switching is toggled via button press.

4. Landing Gear Animation Playback

• Challenge: Playing animation by name is not scalable, as animation names can change.
• Solution: Assigned the animation clip in the inspector and used .name to play it dynamically from the Animator.

5. Making AudioManager a Singleton

• Reasoning: While the project currently has a limited number of audio clips, ensuring scalability from the start is a best practice.
• Implementation: Converted AudioManager into a Singleton to manage audio playback efficiently.

6. TrackedPoseDriver Preventing Rotation Adjustments

• Issue: TrackedPoseDriver on the camera was preventing manual setting of rotation to Third-Person View (TPV).
• Todo: Need further testing to find a way out.

7. Keeping Control-Tracked UI Always in View

• Problem: UI elements were not always visible when the user changed their view.
• Solution: Implemented a control-tracked control UI that remains in view regardless of camera view changes.
