Features

Interactive Terminal System

• Unix-style command-line interface with 20+ commands
• Real portfolio data integration (education, experience, skills, achievements)
• Command history navigation with up/down arrow keys
• Direct links to GitHub, LinkedIn, and live resume
• System commands: uname, date, uptime, hostname, pwd, ls, cat, echo
• Portfolio commands: about, education, experience, skills, achievements, techstack

Dual Mode Experience

• OS Mode: Focused desktop interface for browsing projects and using the terminal
• Explore Mode: Free-look 3D navigation of the virtual environment
• Seamless transitions with smooth camera tweening and FOV adjustments
• Cursor lock/hide management for optimal UX in each mode

Dynamic Content Loading

• GitHub repository showcase with real-time data from GitHub API
• Local JSON caching for WebGL compatibility (CORS workaround)
• Hackathon timeline with event details and project links
• Cache-busting mechanisms for fresh data retrieval

Customization & Settings

• Volume control with dB conversion for AudioMixer
• "Disable 3D" mode for accessibility (OS-only experience)
• Persistent settings using PlayerPrefs
• Mobile support with click-to-focus interaction

Technical Highlights

• Aspect ratio-aware camera positioning for screen quad rendering
• Custom cursor management system independent of script lifecycle
• Responsive UI with TextMeshPro and Unity UI components
• Manual JSON parsing for complex nested data structures

Tech Stack

• Engine: Unity 2025.1
• UI: TextMeshPro, Unity UI (Canvas, ScrollRect, Layout Groups)
• Networking: UnityWebRequest for API calls
• Data: JSON parsing, PlayerPrefs persistence
• Audio: AudioMixer with logarithmic volume conversion
• Deployment: WebGL with CORS handling
