Play a sound only once?

Questions & Answers
1

I have a script attached to an empty game object that waits until the player is at a distance of 10 from it, then plays a sound. The only problem is that when I get close to the game object the sound starts repeating and doesn’t stop. How can I make it so the sound just plays once and never again? I’ve been looking around for solutions for hours now, and I’ve tried everything I can think of, but nothing works right.

var player : GameObject;
var VoiceClip : AudioClip;

function Start() {
    player = GameObject.Find("lindamayfield");

}
        
function Update(){

    //If the player is close then play the sound
    if(Vector3.Distance(transform.position, player.transform.position) < 10)
    {
        audio.clip = VoiceClip;
        audio.Play();
    }

}

You could use a Collider to on trigger when the player enters the collider (using OnCollisionEnter).

Alternatively you could keep track of whether the sound has already been triggered like so:

var player : GameObject;
var VoiceClip : AudioClip;
var hasPlayed = false;

function Start() {
	player = GameObject.Find("lindamayfield");
}

function Update(){
	//If the player is close then play the sound
	if(Vector3.Distance(transform.position, player.transform.position) < 10)
	{
		if (hasPlayed == false)
		{
			hasPlayed = true;
			audio.clip = VoiceClip;
			audio.Play();
		}
	}
	else
	{
		hasPlayed = false;
	}
}

(This assumes you’d want the sound to be able to play again when the player leaves the area, otherwise just remove the bottom hasPlayed = false;)

var player : GameObject;
var VoiceClip : AudioClip;

function Start() {
player = GameObject.Find(“lindamayfield”);

}

function Update(){

//If the player is close then play the sound
if(Vector3.Distance(transform.position, player.transform.position) < 10)
{
    audio.PlayOneShot(VoiceClip);
}

}
