Switch between two different sounds for walking and sprinting?

Questions & Answers
1

So I have two audio files, one for walking and one for sprinting, and I am trying to figure out how to switch between the files depending on if you are walking or sprinting. Here is my script so far:

var walk:AudioClip;
var run:AudioClip;


function Update () {

if ((Input.GetButtonDown( "Horizontal" ) || Input.GetButtonDown( "Vertical" )) && ((Input.GetKey("left shift") || Input.GetKey("right shift")))){
audio.clip=run;
audio.Play();
}

else if ((Input.GetButtonDown( "Horizontal" ) || Input.GetButtonDown( "Vertical" ))){
audio.clip=walk;
audio.Play();
}

else if ((!Input.GetButtonDown( "Horizontal" ) || !Input.GetButtonDown( "Vertical" ))){
audio.Stop();
}

}

When I attach this it doesn’t play any sound at all, even when I am walking or sprinting. Any ideas why this might be? (By the way I am using the first person character controller)

I think it is playing, just playing from the start at every frame ( audio = foo; audio.Play(); ), therefore you never hear the full sound play.

First problem : Input.GetButtonDown( “Horizontal” ) should be Input.GetAxis( “Horizontal” )

I would break it down into 3 steps : find if the character is walking or running; store that information in booleans; then check if the correct audio is playing (if not, set audio clip) then Play =]

Here is a tested working script :

#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();
	}
}
