So I used this tutorial: https://www.youtube.com/watch?v=tLyj02T51Oc, to create an AudioManager that can be easily called from other scripts, and can fade sound effects. One thing I do not know how to do is how to play a sound when let's say the player is running. I only have a function that plays an sfx, but all the SFX have looped equal to false, and I know that a running noise will need the SFX to loop. How can I add a function to this script so that running noises can be correctly implemented? The script:
using System.Collections.Generic;
using UnityEngine;
public class AudioManager : MonoBehaviour
{
#region Instances
private static AudioManager _instance = null;
public static AudioManager Instance
{
get
{
if (_instance == null) //if instance doesn't exist, find an AudioManager
{
_instance = new AudioManager();
}
return _instance;
}
private set
{
_instance = value;
}
}
#endregion
#region Fields
//the audio source can only play one looping sound at a time
private AudioSource musicSource;
private AudioSource musicSource2; //purpose of having 2 musicSources is that we can use them to achieve effects like CrossFade
private AudioSource sfxSource;
private bool firstMusicSourceIsPlaying;
#endregion
private void Awake()
{
if(_instance == null)
{
//Set this instance as the instance reference
_instance = this;
}
else if(_instance != this)
{
//If the instance reference has already been set, and this is not the instance reference, destroy the game object
Destroy(gameObject);
}
//Make sure we don't destroy this instance
DontDestroyOnLoad(_instance);
//Create audio sources, and make them as references
musicSource = this.gameObject.AddComponent<AudioSource>();
musicSource2 = this.gameObject.AddComponent<AudioSource>();
sfxSource = this.gameObject.AddComponent<AudioSource>();
//loop musicSource
musicSource.loop = true;
musicSource2.loop = true;
}
//plays the music
public void PlayMusic(AudioClip musicClip)
{
//Determine which source is active (if the boolean is true, play musicSource, else play musicSource2)
AudioSource activeSource = (firstMusicSourceIsPlaying) ? musicSource : musicSource2;
activeSource.clip = musicClip;
activeSource.volume = 1; //volume is between 0 and 1
activeSource.Play();
}
//fade out the first music, fade in the second (new) music
