How to play a random audio clip from an array in C#?

Question

Hello!

So I've made an audio array like this:

public AudioClip[] shoot;

And placed two audio clips inside of it. Now my question is; how do I play a random audio clip from that array? All the methods I've seen online used obsolete code.

USING: Unity 5.3.5f1

My code works the same, but runs a random clip every 10 seconds. I figured this may be useful to someone at some point.

 using UnityEngine;
 using System.Collections;
 
 public class RandomSoundsScript : MonoBehaviour {
 
     public AudioSource randomSound;
 
     public AudioClip[] audioSources;
 
     // Use this for initialization
     void Start () {
 
         CallAudio ();
     }
 
 
     void CallAudio()
     {
         Invoke ("RandomSoundness", 10);
     }
 
     void RandomSoundness()
     {
         randomSound.clip = audioSources[Random.Range(0, audioSources.Length)];
         randomSound.Play ();
         CallAudio ();
     }
 }

Thanks! This helped me make a simple music randomizer.

using System.Collections; using System.Collections.Generic; using UnityEngine;

 public class $$anonymous$$usicRandomizer : $$anonymous$$onoBehaviour
 {
     public AudioClip[] audioClips;
     public AudioSource audioSource;
     public AudioListener audioListener;
 
     // Start is called before the first frame update
     void Start()
     {
         audioListener = GetComponent<AudioListener>();
         audioSource = gameObject.GetComponent<AudioSource>();
     }
 
     // Update is called once per frame
     void Update()
     {
         if (!audioSource.isPlaying)
         {
             PlayRandom();
         }
     }
     void PlayRandom()
     {
         audioSource.clip = audioClips[Random.Range(0, audioClips.Length)];
         audioSource.Play();
        
     
     }
 
 
 
     
 }

As an example, this will choose a random clip from the array and play it when you press space.

 private AudioSource audioSource;
 public AudioClip[] shoot;
 private AudioClip shootClip;


 void Start()
 {
     audioSource = gameObject.GetComponent<AudioSource>();
 }

 void Update()
 {
     if (Input.GetKeyDown(KeyCode.Space))
     {
         int index = Random.Range(0, shoot.Length);
         shootClip = shoot[index];

         audioSource.clip = shootClip;
         audioSource.Play();
     }
 }

Random.Range is how you can get a random entry from any kind of array and of any length.

     public AudioClip[] sound;
     AudioSource audioSource;
 
      private void Start() {
         audioSource = this.GetComponent<AudioSource>();
     }
 
     public void PlaySound()
     {
         int rand = Random.Range(0, sound.Length);
         audioSource.clip = sound[rand];
         audioSource.Play();
     }

and call PlaySound() with GetComponent().PlaySound() from anywhere

It should be Random.Range(0, sound.Length), because the second parameter is exclusive.

@zwcloud yes you are right, I didn't see that.
