How to Keep Playing Background Music Across Scenes in Unity

One common challenge faced by developers creating games in Unity is ensuring that background music continues seamlessly as players transition between different scenes. If you've encountered this problem, you're not alone! Many developers find themselves frustrated when the audio restarts, breaking immersion. In this guide, we will explore a straightforward solution that you can implement to ensure your background music keeps playing without interruption.

The Problem

Imagine your players are enjoying the ambient music in your game when suddenly, during a scene transition, the music stops, leading to a jarring experience. This can negatively impact the overall feel of your game. You may have tried solutions, such as attaching audio sources to objects in each scene or creating singleton patterns, but those may not have worked as expected.

The Setup

Here's a brief overview of the setup you might have:

You created a prefab containing an audio source to play your music.

You added a script to control the playback of the music.

You tagged your prefab appropriately with "BGAudio".

Despite these steps, the audio still gets cut off during transitions, leaving you searching for answers.

The Solution

To ensure your background music continues playing without any interruptions, we need to correctly utilize the DontDestroyOnLoad method in Unity. Here’s how to do that:

1. Understanding DontDestroyOnLoad

The DontDestroyOnLoad function is essential for keeping game objects alive between scene changes. However, an important detail to note is that it only works for objects that are at the root level in the hierarchy. If your audio source is nested within another game object, it will not persist when you load a new scene.

2. Modify Your Structure

To resolve the issue:

Move your Audio Prefab: Ensure that your prefab with the audio source is at the root level of the game object hierarchy. To do this, create an empty game object and place the audio prefab directly under it without any other layers of nested objects.

3. Update Your Script

Your existing script is on the right track, but ensure that it looks like this after adjustment:

This script checks for other instances of game objects with the "BGAudio" tag and deletes any duplicates, ensuring that only one audio source remains as you move through your scenes.

4. Testing Your Changes

With these modifications, you should now be able to:

Load different scenes without the background music stopping.

Maintain the volume and playback state of your audio.

Additional Tips

Singleton Pattern: If you wish to have more control over your audio source, consider implementing a singleton pattern to manage it. This pattern helps in managing the lifecycle of your audio source more elegantly.

Audio Settings: Make sure your audio settings in Unity are appropriately configured for continuous playback.

Conclusion

By following these steps, you can ensure that your background music plays continuously across all scenes in your Unity game, providing a more immersive experience for players. Implementing DontDestroyOnLoad properly will solve the most common issues associated with audio playback during scene transitions.
