Playing a soundclip at random from an array. C#

I’ve never really worked with audio coding before but I need to play a sound clip at random from a group of 5 whenever the player hits an object. Right now I’ve just got it in some test code and once I’ve got things figured out I’ll trasplant it into the correct code.

public AudioSource[] DamageClips;
public GameObject Thief;

void Start () 

		Thief = GameObject.FindGameObjectWithTag ("Thief");

		AudioClip nextClip = Random.Range (0, DamageClips.Length);

		audio.clip = nextClip;

void TouchHasBegun()
		Ray ray = Camera.main.ScreenPointToRay( screenPos );
		RaycastHit hit;
		if ( Physics.Raycast( ray, out hit ) )
			hit.collider.gameObject.SendMessage("OnClick", SendMessageOptions.DontRequireReceiver);
			//Debug.Log("PAUSE GODDAMN IT");
		//if (falling == false && levelStart == true && jumpHasPlayed == false)
			//this.rigidbody.useGravity = true;

			//levelStart = false;
			//falling = true;
			//Camera.main.backgroundColor =;

		else if(camTransform.position.y <= 170.0f)
			anchor.rigidbody.constraints = RigidbodyConstraints.FreezeAll;	
			isFallingPlaying = false;
			audio.Play(DamageClips[Random.Range (0,DamageClips.Length)]);

I’ve looked through some other answers, which is where I got what I have here but I’m getting a few errors.

Cannot implicitly convert type int' to UnityEngine.AudioClip’

The best overloaded method match for `UnityEngine.AudioSource.Play(ulong)’ has some invalid arguments

Argument #1' cannot convert UnityEngine.AudioSource’ expression to type `ulong’

To be quite honest, I have no idea what I’m doing here so I don’t really know how to fix these. Any help would be greatly appreciated.

Also, I have taken chunks my code out to post what I have here, most of it has nothing to do with the audio.

I couldn’t help but envision Cartman when I read

//Debug.Log(“PAUSE GODDAMN IT”);

Take a look at this question/answer for a simple syntax example

You need to change DamageClips to be AudioClips instead of AudioSources:
public AudioSource DamageClips; to public AudioClip[] DamageClips;

Then, in ‘Start’ change this AudioClip nextClip = Random.Range (0, DamageClips.Length); to AudioClip nextClip =DamageClips[ Random.Range (0, DamageClips.Length)];
