How to use audio commands and Audio Source?

Question

Hi

I have some questions about sound in Unity.

1: How do I use a Audio Source? Can I put a empty Audio Source on an object and then put use a scrpit to control sounds? I play different AudioClip variables.

2: What more functions regarding sound are there than PlayOneShot? I have tried Play and Stop, but it does not work as planned.

Hey, I am new to unity and not much of a programmer, but I have the same problem. I think I can answer one part.

I created an Empty gameObject, gave it the component Audio Source (untick play on awake, and leave the audio clip box at None / empty). Then I applied this script. (Don't forget to add the sounds to the prefab / object in the inspector after you have attached the script and component audio source).

 // random sounds script
 // ----
 
  
 // Inspector Variables
 
 // Sounds
 
 var scream1 : AudioClip;
 var scream2 : AudioClip; 
 var scream3 : AudioClip; 
 var screamSound : AudioClip;
 var randomSound : int = 0;
 
 // ----
 
 // Game Loop
 function FixedUpdate ()
 {
     // when you want to play a sound (one shot) , call the function
     // playSound ();
 }
 
 // ----
 
 //
 function playSound ()
 {    
     randomSound = Random.Range(0,10);
 
     if ((randomSound >= 0) && (randomSound <= 3)) {screamSound = scream1;}
     if ((randomSound > 3) && (randomSound <= 6)) {screamSound = scream2;}
     if ((randomSound > 6) && (randomSound <= 10)) {screamSound = scream3;}    
 
     audio.PlayOneShot(screamSound);
 }
 
 // ----

for pausing or playing a sound, I have exactly the same problem, but these commands work when you attach the component audio source and place the sound in the audio clip box :

audio.volume = 0.0; audio.mute = true;

audio.volume = 1.0; audio.mute = false;

apart from that , I hope you get an answer so we both find out how to play / pause audioclip audio.Play();

:)

@alucardj, you could do it more easier with a switch statement:

function playSound ()
{   
    randomSound = Random.Range(0,3);
    switch (randomSound){
      case 0: screamSound = scream1; break;
      case 1: screamSound = scream2; break;
      case 2: screamSound = scream3; break;
    }
    audio.PlayOneShot(screamSound);
}

Or even easier yet using an array:

var screams: AudioClip[]; // set size and fill it in the Inspector

function playSound () {
audio.PlayOneShot(screams[Random.Range(0, screams.length)]); }

ahh, thanku very much. I came to unity from flash, and one command i was missing the most was switch - case. But the array method is the most elegant. (my bad random range scale was a leftover from before i realized Random.Range(0.0, 2.0) gave float , rr(0, 2) gave int. I should've fixed that too) $$anonymous$$any thanks.

Help please. I have implemented the array solution as exampled above. I have an audio listener attached to the same prefab that the audio script is attached too with the array. I have two audio clips assigned to the array via the inspector. The only time audio works is when I actually assign an audio clip to the audio source, then, that's the only audio that gets played, not a random mix of the two.

 using UnityEngine;
 using System.Collections;
 
 public class Target : MonoBehaviour {
 
     public AudioClip[] audioClips;
 
     void Start () { }
 
     void Update () { }
     
     public void TargetHit ()
     {
         Debug.Log("Made it to Target.cs script");
         audio.PlayOneShot(audioClips[Random.Range(0,audioClips.Length)]);
         Destroy(this.gameObject);
         //Destroy(GameObject.Find("Target(Clone)"));
     }
 }
