Play sond once when attacking

Hello!

I am trying to make a platform game in flash and want the character to play a sound everytime i hit the attackbutton, but only once.

I´ve tried everything i can come up with, but the sound just keeps looping over and over.
What to do?

Code for the attack:

if (Key.isDown(_root.ATTACKKEY)) {
//if the player is pushing the attack key

    if (_root.mcPLAYER.GROUNDED == true && _root.ATTACK == 1) {
        //if the player is grounded
        if (_root.mcPLAYER.DIRECTION == "R") {
            //if the player is facing right
            _root.mcPLAYER.gotoAndPlay(13);
            //show the player attack facing right frame
        } else {
            //if the player is facing left
            _root.mcPLAYER.gotoAndPlay(14);
            //show the player attack facing left frame
        }

and in the mcPLAYER frame 13 and 14, I have placed the sound in the timeline and at the end I also put stop();

However… it keeps repeating…

Can anyone help me? Thanks for your time :slight_smile:
