Footstep Scipt, (What is wrong?)

using UnityEngine;
using System.Collections;

public class Footsteps : MonoBehaviour {

public AudioClip[] footsteps;
public float nextFoot;

IEnumerator Start () 
{CharacterController controller = GetComponent<CharacterController> ();

	while (true) {
		if(controller.isGrounded && controller.velocity.magnitude > 0.3F)
		{
			audio.PlayOneShot(Footsteps[Random.Range(0, Footsteps.Length)]);
			yield return new WaitForSeconds(nextFoot);
			
			}
		else
		{ 
			yield return 0;
		}

any help would be appreciated.

I am trying to get a footsteps script, but I have been having no luck I keep getting this error.
Assests/Footsteps.cs(17.51): error CS0119: expression denotes a ‘type’, where a ‘variable’,‘value’, or ‘method group’ was expected

Not quit sure what to do I am a beginner at Unity.

When I try and compile your code, I don’t get that specific error. Is is possible you have a Footsteps class in your project? Anyway, the only issue I see is on line 12. You want ‘footsteps’ with a lower case ‘f’ in the two places you use ‘Footsteps’ in this line of code. Youalso want to return null instead of ‘0’.

using UnityEngine;
using System.Collections;

public class Bug25a : MonoBehaviour {

	public AudioClip[] footsteps;
	public float nextFoot;

	IEnumerator Start () {
		CharacterController controller = GetComponent<CharacterController> ();
		
		while (true) {
			if(controller.isGrounded && controller.velocity.magnitude > 0.3F)
			{
				audio.PlayOneShot(footsteps[Random.Range(0, footsteps.Length)]);
				yield return new WaitForSeconds(nextFoot);
				
			}
			else
			{ 
				yield return null;
			}
		}
	}
}

I got the answer but in JavaScript… If its any help here it is:

#pragma strict
 
var walk : AudioClip;
var run : AudioClip;
 
var isWalking : boolean = false;
var isRunning : boolean = false;
 
 
function Update()
{
GetState();
PlayAudio();
}
 
 
function GetState()
{
if ( Input.GetAxis( "Horizontal" ) || Input.GetAxis( "Vertical" ) )
{
if ( Input.GetKey( "left shift" ) || Input.GetKey( "right shift" ) )
{
// Running
isWalking = false;
isRunning = true;
}
else
{
// Walking
isWalking = true;
isRunning = false;
}
}
else
{
// Stopped
isWalking = false;
isRunning = false;
}
}
 
 
function PlayAudio()
{
if ( isWalking )
{
if ( audio.clip != walk )
{
audio.Stop();
audio.clip = walk;
}
 
if ( !audio.isPlaying )
{
audio.Play();
}
}
else if ( isRunning )
{
if ( audio.clip != run )
{
audio.Stop();
audio.clip = run;
}
 
if ( !audio.isPlaying )
{
audio.Play();
}
}
else
{
audio.Stop();
}
}
