OpenMusicPlayer - Friendly Music Player 🎵 for Unity

Overview

OpenMusicPlayer is a flexible, event-driven music player system for Unity that provides robust playlist management, playback control, and seamless UI integration. Designed for both simple implementations and complex audio systems, it's perfect for games, simulations, and VR experiences.

Features

• 🎵 Dynamic playlist management with ScriptableObjects
• 🔄 Multiple playback modes (loop, shuffle, sequential)
• 🎚️ Volume control with smooth transitions
• 🎛️ UI integration with visual feedback
• 🚀 Event-driven architecture for easy extensibility
• 📦 Plug-and-play prefab system
• 🎮 VR-ready design

Installation

Add to your Unity project via UPM:

openupm add https://github.com/yourusername/OpenMusicPlayer.git

Quick Start

1. Create a Playlist
   • Right-click in Project window → Create → Audio → Music Playlist
   • Add songs and configure settings
2. Add to Scene
   • Drag MusicPlayerCore.prefab into your scene.
   • Assign your playlist in the Inspector.
3. Add UI
   • Use the included MusicPlayerUI.prefab or create your own.
   • Connect UI elements to the MusicPlayerCore events
4. Control Playback

   // In your game code
   MusicPlayerCore player = FindObjectOfType<MusicPlayerCore>();
   player.Play();
   player.NextTrack();
   player.SetVolume(0.7f);

Samples

Import samples from the Package Manager details on Open Music Player.

1. If not found in project, you will be asked to Import TextMeshPro Essentials because we are using the base font.
2. Reload any current Sample scene if already loaded.

Best Practices

1. Use ScriptableObjects for playlist management - makes it easy to swap playlists.
2. Subscribe to events rather than polling for state changes.
3. Use the default song to show "no music" state in UI.
4. Adjust progressUpdateInterval based on performance needs.
5. Use volumeDelta for consistent volume steps.

Advanced Usage

Custom UI Implementation

public class CustomPlayerUI : MonoBehaviour
{
    [SerializeField] private Image playIcon;
    [SerializeField] private Slider progressBar;
    
    private MusicPlayerCore player;
    
    void Start()
    {
        player = FindObjectOfType<MusicPlayerCore>();
        player.OnPlaybackStateChanged += state => {
            playIcon.color = state == PlaybackState.Playing ? Color.green : Color.white;
        };
        
        player.OnPlaybackProgress += progress => {
            progressBar.value = progress;
        };
    }
}

Playlist Management

// Create playlist at runtime
MusicPlaylistScriptableObject runtimePlaylist = ScriptableObject.CreateInstance<MusicPlaylistScriptableObject>();
runtimePlaylist.songs = new List<Song>(customSongs);
player.LoadPlaylist(runtimePlaylist);

// Add songs dynamically
player.AddSong(new Song {
    title = "New Song",
    artist = "Artist",
    clip = newAudioClip
});

VR Integration Example

public class VRMusicController : MonoBehaviour
{
    [SerializeField] private XRController controller;
    [SerializeField] private MusicPlayerCore player;
    
    void Update()
    {
        if(controller.inputDevice.TryGetFeatureValue(CommonUsages.primaryButton, out bool pressed) && pressed)
        {
            player.NextTrack();
        }
    }
}

Troubleshooting

Issue	Solution
No sound	Check AudioClip assignment in playlist
UI not updating	Verify event subscriptions
Playback stuttering	Increase endOfSongThreshold
Progress bar jitter	Add SliderInteractController component
Shuffle not working	Call GeneratePlayOrder() after playlist changes
