Can't get PlayOneShot() or Play() to work

Question

I'm trying to get gun sounds to work, but I'm having trouble getting PlayOneShot() or Play() to work. Here is my code:

     using UnityEngine;
     using System.Collections;
     
     public class Guns : MonoBehaviour {
         public Rigidbody projectile;
         public float speed = 6000;
         public AudioSource mg_spinup;
         public AudioSource minigun_firing;
         public AudioSource mg_spindown;
         
         // Update is called once per frame
         void Update () {
     
             if (Input.GetButton ("Fire1")) {
     // This line fires the projectile, timing of this is off, don't worry about it for now.
                 Rigidbody instantiatedProjectile = Instantiate(projectile,transform.position,transform.rotation)as Rigidbody;
                 instantiatedProjectile.velocity = transform.TransformDirection(new Vector3(0, 0,speed));
    // This gun spins up before it starts firing, so here's the spinup sound
                 mg_spinup.PlayOneShot(mg_spinup, 1.0f);
     
     
                 if (Input.GetButton ("Fire1")){
             // While the fire button is being pressed, play the minigun firing sound
                     minigun_firing.Play(minigun_firing,4.0f);
                 }
             }
             
             if (Input.GetButtonUp ("Fire1")) {
              // When the player releases the fire button, spin down the weapon.
                     mg_spindown.PlayOneShot(minigun_spindown, 1.0f);
             } 
         }
     }

Unity currently throws the following error in the console:

Assets/My Assets/Scripts/CSharp/Guns.cs(19,35): error CS1503: Argument #1' cannot convert UnityEngine.AudioSource' expression to type UnityEngine.AudioClip' If I switch my AudioSources to AudioClips, I get this error: > Assets/My Assets/Scripts/CSharp/Guns.cs(19,35): error CS1061: Type UnityEngine.AudioClip' does not contain a definition for PlayOneShot' and no extension method PlayOneShot' of type UnityEngine.AudioClip' could be found (are you missing a using directive or an assembly reference?) > Assets/My Assets/Scripts/CSharp/Guns.cs(23,48): error CS1061: Type UnityEngine.AudioClip' does not contain a definition for Play' and no extension method Play' of type `UnityEngine.AudioClip' could be found (are you missing a using directive or an assembly reference?)

So, it seems as though Unity doesn't want to use either AudioSources or AudioClips... what am I doing wrong here?

Answer 1

You are mixing up what an audio clip and an AudioSource is.

To Play Audio : http://docs.unity3d.com/ScriptReference/AudioSource.Play.html

Assign a clip to the AudioSource, tell the AudioSource to Play :

 public AudioClip mySound;
 public AudioSource mySource;

 // in method, assign the clip to the audioSource
 mySource.clip = mySound;
 // AudioSource.Play();
 mySource.Play();

To PlayOneShot : http://docs.unity3d.com/ScriptReference/AudioSource.PlayOneShot.html

assign the clip to play and the volume in one command :

 public AudioClip mySound;
 public AudioSource mySource;
 public float myVolume = 1.0f;

 // in method
 // AudioSource.PlayOneShot( clip, volume );
 mySource.PlayOneShot( mySound, myVolume );

It is hard to help any further without knowing if you are trying to assign clips to your variables or AudioSources.

If it is an AudioSource, your PlayOneShot would look like this :

 // the clip is already assigned on the AudioSource
 mg_spinup.PlayOneShot( mg_spinup.clip, 1.0f );

and your play would look like this :

 // the clip is already assigned on the AudioSource
 minigun_firing.volume = 4.0f;
 minigun_firing.Play();
