2. 🔧 Core Systems: Physics, Animation, UI

• Physics & Collisions
  • Use Rigidbody, Colliders, and Physics Materials.
  • Implement triggers, collisions, and object interactions.
• Animation
  • Create animations with Animator & Animation components.
  • Design animation state machines and control them via script.
• UI Development
  • Work with Canvas, Buttons, Text, Images, Sliders, etc.
  • Build menus, HUDs, and handle user interactions.

3. 🧠 Advanced Systems: Audio, AI, Multiplayer

• Audio Integration
  • Use AudioSource, AudioClip, and AudioListener.
  • Add background music, SFX, and manage audio behavior.
• AI & Pathfinding
  • Implement navigation using NavMesh.
  • Create AI behaviors: patrol, chase, and avoid.
  • Use state machines or behavior trees.
• Multiplayer Networking
  • Explore frameworks: UNet, Mirror, Photon.
  • Sync player states and implement client-server communication.

4. 🎨 Visual & Performance: Optimization, Shaders, Tools

• Performance Optimization
  • Reduce draw calls, use object pooling, optimize physics/UI.
  • Analyze with the Profiler and optimize memory usage.
• Shaders & VFX
  • Learn Shader Graph and basic shader scripting.
  • Create lighting effects, particles, post-processing.
• Editor Tooling
  • Build custom editor tools for workflows.
  • Use the Editor API for automation and debugging utilities.

5. 📱 Cross-Platform Development & Release

• Platform Deployment
  • Develop for PC, mobile, console, VR/AR.
  • Optimize input and resolution for each platform.
• Team Collaboration
  • Use Git for version control.
  • Coordinate assets/code with Unity Collaborate or external tools.
• Publishing & Maintenance
  • Publish on Steam, App Store, Google Play.
  • Prepare builds, manage updates, gather feedback.

---

6. 🕶️ Extended Reality: VR & AR

• VR Development
  • Use XR Toolkit for devices like Oculus, HTC Vive.
  • Implement immersive controls and optimize comfort/performance.
• AR Development
  • Build AR apps using AR Foundation.
  • Enable features like plane detection, image tracking, and real-world interactions.

---

7. 🎯 Final Stage: Build a Full Game

• Game Design
  • Define gameplay loops, goals, and user experience.
  • Plan features and timeline.
• Project Execution
  • Develop a complete game using modular systems.
  • Manage releases, bugs, and user testing in agile cycles.
