AsteroidsAR: A Classic Arcade Game Reimagined in Augmented Reality

AsteroidsAR Demo

AsteroidsAR is an AR version of the classic arcade game Asteroids, developed as a course project for the Meta AR Developer Certification. This engaging application allows players to defend Earth against incoming asteroids using their phone camera and aiming skills.

Key Features

• AR Integration: Utilizes the phone camera to create an immersive augmented reality experience.
• Gameplay Mechanics: Players shoot asteroids before they hit Earth, with large asteroids breaking into smaller ones, increasing the challenge and points.
• Enemy UFOs: Occasionally appearing UFOs shoot at the player. Successfully destroying them grants health pickups, weapon upgrades, or both.
• User Interface: Title screen, gameover screen and HUD that includes a crosshair for aiming, a health bar for the player and Earth, and screen tints for damage (red), health pickups (green), and weapon upgrades (purple).
• Sound and Particle Effects: Enhance the gameplay experience with various sound effects for shooting, explosions, and upgrades, along with visual explosions for asteroid destruction.
• Target Platform: AR-enabled Android devices.

Techniques and Coding

• Scriptable Objects: Utilized to maintain game state.
• Coroutines: Used for handling asynchronous processes without blocking the main game loop.
• UnityEvents: Facilitated interaction between different scripts, such as updating the health bar when damaged or when health pickup is received.

Extra Features

• Title Screen: Added a title screen with simple game instructions and a play button, enhancing the user experience by providing a structured game start.
• Weapon Upgrade: Implemented a unique weapon upgrade pickup that generates a straight laser beam from the player, destroying anything in its path for 10 seconds.
• Screen Tints: Introduced visual feedback where the screen flashes red on damage, gives a green tint for health pickups, and a purple tint during the weapon upgrade, improving gameplay feedback.

Assets Used

• 3D Models: Provided in the course.
• Sound Effects: Sourced from Arcade SFX Free on the Unity Asset Store.
• Particle Effects: Sourced from Hit Impact Effects Free on the Unity Asset Store.

AsteroidsAR is an immersive AR experience, integrating advanced coding techniques and enhancing user interaction with thoughtful UI and gameplay elements.
