BeyBlade Multiplayer AR 🔥

A Unity-based mobile game that brings classic Beyblade battles into the real world using Augmented Reality and Multiplayer Networking.

Built using Unity C#, AR Foundation (ARKit & ARCore), and Photon PUN2, this prototype demonstrates real-time AR battles between two players using network-synced Beyblade tops and realistic physics interactions.

Project Highlights ✨

• AR Arena Placement

  • Detect flat surfaces like tables or floors using AR Foundation.
  • Spawn a virtual Beyblade arena directly onto real-world space.

• Multiplayer Battles

  • Two players join the same room via Photon PUN2.
  • Each player's Beyblade is synced in real-time: launch, spin, collide.

• Physics-Based Gameplay

  • Swipe or flick to launch your Beyblade.
  • Unity physics simulate spin, force, friction, and impacts.

• Real-Time Sync

  • Uses PhotonNetwork.Instantiate() and PhotonViews to sync objects across devices.
  • Consistent arena placement, rotation, and state on both devices.

Objective 💡

Build a cross-platform AR multiplayer experience to:

• Learn how to use AR Foundation to anchor 3D objects in the real world.
• Integrate Photon PUN2 for matchmaking and real-time object synchronization.
• Simulate realistic Beyblade physics using Rigidbody, Colliders, and collision detection.
• Demonstrate full-stack multiplayer AR game development using industry-standard tools.

---

Gameplay 🎮

• Scan a flat surface to spawn the arena.
• Join or create a Photon room.
• Launch your Beyblade and watch the battle unfold in AR.
• Tops collide, spin, and bounce using Unity's physics.
• All interactions are mirrored across players in real-time.

Getting Started 📃

• Unity Version: 2020.3 LTS or later
• Requirements:
  • AR Foundation
  • ARKit XR Plugin (iOS)
  • ARCore XR Plugin (Android)
  • Photon PUN2
  • ARKit/ARCore supported mobile device

---

Setup Instructions ⚙️

1. Install AR Foundation & plugins via Unity Package Manager.
2. Enable XR Plug-in Management and select ARKit or ARCore for your target platform.
3. Import Photon PUN2 and add your App ID in PhotonServerSettings.
4. Open the project in Unity Hub and load the MainScene.
5. Connect to Photon, join/create a room, and place the arena in AR.
6. Build and deploy to a real mobile device for full functionality.

Core Components 🛠️

Photon Networking

• Launcher.cs: Connects to Photon and manages room flow.
• PhotonNetwork.Instantiate(): Spawns networked Beyblade prefabs.
• PhotonView: Ensures transforms and logic are synced.
• OnJoinedRoom, OnPlayerLeft: Manage multiplayer events.

Vector3 spawnPosition = new Vector3(0, 0.1f, 0);
PhotonNetwork.Instantiate("BeybladePrefab", spawnPosition, Quaternion.identity);

AR Integration

• ARPlaneManager: Detects horizontal surfaces.
• ARAnchorManager: Anchors arena/Beyblade prefabs to planes.
• Keeps virtual content fixed to real-world positions.

List hits = new List();
if (arRaycastManager.Raycast(touchPos, hits, TrackableType.PlaneWithinPolygon)) {
    Pose hitPose = hits[0].pose;
    Instantiate(arenaPrefab, hitPose.position, hitPose.rotation);
}

Game Logic

• Beyblade prefabs include Rigidbody, Collider, and custom spin logic.
• Launch force is applied via touch or motion input.
• Collision events (via OnCollisionEnter) trigger effects or knockouts.

void OnCollisionEnter(Collision other) {
    if (other.gameObject.CompareTag("Beyblade")) {
        // Apply damage or bounce logic here
    }
}

Skills Demonstrated 💻

• Unity C# Scripting – Touch input, physics, prefab control, and multiplayer.
• AR Development – Used AR Foundation to deploy to both iOS and Android with one codebase.
• Multiplayer Sync – Photon PUN2 for networked object control and scene management.
• Physics & Effects – Realistic movement, collision, and feedback using Unity’s physics engine.

Preview 👀

Two players face off with phones aimed at the same table.
Each sees the same arena and spinning tops clashing in real time.
Battles play out with realistic motion, sound, and synced interaction.
