Music Manager

i got this code, but there is an error, it says that
IndexOutOfRangeException: Array index is out of range.
AudioManager.Start () (at Assets/AudioManager.cs:34)
how can i fix it??

here's the code..

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3.  
4. public enum SoundEffects { ObstacleCollisionSoundEffect, CoinSoundEffect, PowerUpSoundEffect, GameOverSoundEffect, GUITapSoundEffect }
5. public class AudioManager : MonoBehaviour {
6.    
7.     static public AudioManager instance;
8.    
9.     public AudioClip backgroundMusic;
10.     public AudioClip obstacleCollision;
11.     public AudioClip coinCollection;
12.     public AudioClip powerUpCollection;
13.     public AudioClip gameOver;
14.     public AudioClip guiTap;
15.    
16.     public float backgroundMusicVolume;
17.     public float soundEffectsVolume;
18.    
19.     private AudioSource backgroundAudio;
20.     // use multiple sound effects audo sources so more than one sound effect can be played at the same time
21.     private AudioSource[] soundEffectsAudio;
22.     private int nextSoundEffectsAudioIndex = 0;
23.    
24.     public void Awake()
25.     {
26.         instance = this;
27.     }
28.    
29.     public void Start()
30.     {
31.         AudioSource[] sources = Camera.main.GetComponents<AudioSource>();
32.         //backgroundAudio = sources[0];
33.         soundEffectsAudio = new AudioSource[2];
34.         soundEffectsAudio[0] = sources[1];
35.         soundEffectsAudio[1] = sources[2];
36.        
37.         backgroundAudio.clip = backgroundMusic;
38.         backgroundAudio.loop = true;
39.         backgroundAudio.volume = Mathf.Clamp01(backgroundMusicVolume);
40.        
41.         soundEffectsAudio[0].volume = Mathf.Clamp01(soundEffectsVolume);
42.         soundEffectsAudio[1].volume = Mathf.Clamp01(soundEffectsVolume);
43.     }
44.    
45.     public void playBackgroundMusic(bool play)
46.     {
47.         if (play) {
48.             backgroundAudio.Play();
49.         } else {
50.             backgroundAudio.Pause();
51.         }
52.     }
53.    
54.     public void playSoundEffect(SoundEffects soundEffect)
55.     {
56.         AudioClip clip = null;
57.         float pitch = 1;
58.         switch (soundEffect) {
59.         case SoundEffects.ObstacleCollisionSoundEffect:
60.             clip = obstacleCollision;
61.             break;
62.            
63.         case SoundEffects.CoinSoundEffect:
64.             clip = coinCollection;
65.             pitch = 1.5f;
66.             break;
67.            
68.         case SoundEffects.PowerUpSoundEffect:
69.             clip = powerUpCollection;
70.             break;
71.            
72.         case SoundEffects.GameOverSoundEffect:
73.             clip = gameOver;
74.             break;
75.            
76.         case SoundEffects.GUITapSoundEffect:
77.             clip = guiTap;
78.             break;
79.         }
80.        
81.         soundEffectsAudio[nextSoundEffectsAudioIndex].pitch = pitch;
82.         soundEffectsAudio[nextSoundEffectsAudioIndex].clip = clip;
83.         soundEffectsAudio[nextSoundEffectsAudioIndex].Play();
84.         nextSoundEffectsAudioIndex = (nextSoundEffectsAudioIndex + 1) % soundEffectsAudio.Length;
85.     }
86. }
87.  

 

The Camera referenced by Camera.main does not have any AudioSource components on it.

 

so should i put the script on the camera??

 

No.

According to the code you are using, the main camera needs a total of 3 AudioSource components attached to it.
