Hi there - I have background music on my main menu, which continues playing through each menu. However, when I load my first level, I want this music to stop. I have tried a few methods of solving this, but haven’t been able to get a working fix. Any help would be hugely appreciated!
Here’s my code:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.SceneManagement;
public class MusicPlay : MonoBehaviour
{
public static MusicPlay musicplay;
public GameObject music;
In the update of this script, or preferably in the Start method of another script, you could destroy the music object when entering a specific scene. For example:
void Update()
{
Scene currentScene = SceneManager.GetActiveScene();
if (currentScene.name == "Level1")
{
// Stops playing music in level 1 scene
Destroy(gameObject);
}
}
Don’t use scene names in a script that is attached to an object in a different scene. Since your “MusicPlay” script is a singleton like object, you only have to add another tiny script which actually does the “stopping” or “starting” when the scene is loaded. For example
// BackgroundMusicHandler.cs
using UnityEngine
public class BackgroundMusicHandler : MonoBehaviour
{
public enum Mode {EnsurePlaying, Restart, Stop};
public Mode mode;
void Start()
{
if (mode == Mode.EnsurePlaying)
MusicPlay.musicplay.StartBackgroundMusic(false);
else if (mode == Mode.Restart)
MusicPlay.musicplay.StartBackgroundMusic(true);
else if (mode == Mode.Stop)
MusicPlay.musicplay.StopBackgroundMusic();
}
}
In your “MusicPlay” script you should add those two mentioned methods. Your MusicPlay script should probably cache the AudioSource that is attached to the MusicPlay script so it can easily access the audio source. So it would look something like this:
public class MusicPlay : MonoBehaviour
{
public static MusicPlay musicplay;
// either set backgroundMusic in the inspector or use GetComponent in Awake to initialize this variable
public AudioSource backgroundMusic;
void Awake()
{
if (musicplay == null)
{
DontDestroyOnLoad(gameObject);
musicplay = this;
}
else if (musicplay != this)
{
Destroy(gameObject);
}
}
public void StartBackgroundMusic(bool aRestart)
{
if (!backgroundMusic.isPlaying || aRestart)
backgroundMusic.Play();
}
public void StartBackgroundMusic()
{
backgroundMusic.Stop();
}
}
Now you can simply attach the “BackgroundMusicHandler” to any object in each scene and decide if you want to play background music, if you want to restart it or if you want to stop it.
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.SceneManagement;
public class MusicPlay : MonoBehaviour
{
public static MusicPlay musicplay;
public GameObject music;
private string firstLevelName = "YourFirstLevelSceneName"; // Replace with your actual first level scene name
void Awake()
{
if (musicplay == null)
{
DontDestroyOnLoad(gameObject);
musicplay = this;
}
else if (musicplay != this)
{
Destroy(gameObject);
}
}
private void Start()
{
SceneManager.sceneLoaded += OnSceneLoaded;
}
private void OnSceneLoaded(Scene scene, LoadSceneMode mode)
{
// Check if the newly loaded scene is the first level
if (scene.name == firstLevelName)
{
// Stop the music
StopMusic();
}
}
private void StopMusic()
{
if (music != null)
{
AudioSource audioSource = music.GetComponent<AudioSource>();
if (audioSource != null)
{
audioSource.Stop();
}
}
}
private void OnDestroy()
{
SceneManager.sceneLoaded -= OnSceneLoaded;
}
}
Replace "YourFirstLevelSceneName" with the actual name of your first level scene. This modified script subscribes to the SceneManager.sceneLoaded event, which is triggered when a scene is loaded. When the first level is loaded, it stops the background music.
Make sure to attach this script to the GameObject that controls your background music, and ensure that the GameObject with the background music is tagged as “music” and has an AudioSource component attached to it.
