Script unattached to Object will not compile

Question

I feel like I've hit a catch twenty two:

I am creating a sound script that will instance a whirring noise only when a turret is moving to line up with it's target. I have two scripts that accomplish this. The idea revolves around a Vector3.Angle() function that determines the difference between where the turret is pointed and where it thinks it needs to go. If that value has a nonzero value than it is assumed the turret is in movement. This value is assigned to a var called float_angle.

Soundcounter is a modulus 10 integer that is constantly moving. On the value of soundcounter == 9 the float_angle function updates. On soundcounter == 10 the following script is set to function:

 function soundtrigger () {
     if(soundcounter == 10 && float_angle == 0)targetObject.SendMessage(stop);
     else(soundcounter == 10 && float_angle > 0)targetObject.SendMessage(movement);
 }

This informs the following function:

 SentrySoundManager.js
 var start_rotate : AudioClip;
 var end_rotate : AudioClip;
 private var looping : boolean = false;
 
 function loopState(looping: boolean){
     audio.loop = looping;
 }
 function movement(){
     if (!AudioSource.isPlaying){
         looping = true; 
         audio.PlayOneShot(start_rotate);
     }
     AudioSource.loop = looping;
     yield WaitForSeconds(start_rotate.length);
     audio.Play();
 }
 
 function stop(){
     if (AudioSource.isPlaying){
         looping = false; 
         audio.PlayOneShot(end_rotate);
     }
 }

My issue is that the SentrySoundManager.js will not compile, and further complicates the unity scene by making the rest of the scripts unavailable until the compilation error is resolved. I get the following message in the Console of Unity:

"Assets/WeaponScripts/SentrySoundManager.js(9,26): BCE0020: An instance of type 'UnityEngine.AudioSource' is required to access non static member 'isPlaying'.
Assets/WeaponScripts/SentrySoundManager.js(13,21): BCE0020: An instance of type 'UnityEngine.AudioSource' is required to access non static member 'loop'.
Assets/WeaponScripts/SentrySoundManager.js(19,25): BCE0020: An instance of type 'UnityEngine.AudioSource' is required to access non static member 'isPlaying'."

I don't understand how to instance an AudioSource for a script that is not attached to an Object in the scene. Am I interpreting this incorrectly? Thanks, and if I can clarify anything lemme know.

you need to tell the script which AudioSource in the scene you are talking about.. if (as I assume) the audio source is on the same object as the script, change "AudioSource" to simply "audio":

 var start_rotate : AudioClip;
 var end_rotate : AudioClip;
 private var looping : boolean = false;
  
 function loopState(looping: boolean){
 audio.loop = looping;
 }
 function movement(){
 if (!audio.isPlaying){
 looping = true;
 audio.PlayOneShot(start_rotate);
 }
 audio.loop = looping;
 yield WaitForSeconds(start_rotate.length);
 audio.Play();
 }
  
 function stop(){
 if (audio.isPlaying){
 looping = false;
 audio.PlayOneShot(end_rotate);
 }
 }

if,alternately, the audio source you were after were on another object, like say the turret itself:

  var otherAudio = GameObject.Find("turret").GetComponent(AudioSource);

  if(otherAudio.isPlaying)...etc

Your assumption is correct about the scripts' placement.

I cleared the error I was encountering; thank you for the pointer. Additionally the otherAudio paradigm is helpful too.
