AudioSource does not work for some reason

Questions & Answers

Hi all, I am using the following code to initialise a sound playing:

var sound: AudioSource;
var sound: AudioSource;
function Update () {
    if (Input.GetKey (KeyCode.W))
    {
        sound.Play();
    }
    if (!Input.GetKey(KeyCode.W))
    {
        sound.Stop();
    }
}

For some reason, even though I am using this exact same method to initialise another sound (which works fine), this does not work. I have tried GetButtonDown, and GetKeyDown as well and neither of these work. If I switch the code to the following:

var sound: AudioSource;
    var sound: AudioSource;
    function Update () {
        if (Input.GetKey (KeyCode.W))
        {

        }
        if (!Input.GetKey(KeyCode.W))
        {
            sound.Play();
        }
    }

the sound plays a sudden burst at the beginning for about half a second and then stops, but if I push W down it plays. Unfortunately the sudden burst is very offputting so I cannot use this method. Also if I deselect the game (in windows) the sound loops continuously. Can someone tell me what I am doing wrong as I am deeply confused. :-(

Thanks.

GetKey is true while the key is held. If you want it to start when they hit the key, use GetKeyDown. If you want it to stop when they release the key, use GetKeyUp
