Play thruster sound?

Unity Engine

Hi, I’m trying to get my spaceships thrusters to have a thruster sound play when a certain key is held down.

This script works but it plays the sound “thrust” over and over when I hold down the key:

void Update () {
       
        if(Input.GetKey(KeyCode.S) || Input.GetKey(KeyCode.D))
        {
            audioSource.enabled = true;
            thisParticleRenderer.enabled = true;
            audio.PlayOneShot(thrust);

I know its because its under void update (although I thought PlayOneShot meant play once) but how do I get the sound to play when “S” or “D” is held down and loop but not play over itself on over and over? I hope that made sense :slight_smile: any help is greatly appreciated.

easy way: (start playing the loop only if its not already playing)

if (!audio.isPlaying) audio.Play();

could be nicer if volume gets adjusted when starting to play and the fade out when key is released…

Hey gear, thanks for pointing me in the right direction, this is what worked in my case:

if (!audio.isPlaying) {
                audio.clip = thrust;
                audio.Play ();
            }

I’m not sure how to make the sound fade in and out upon key touch but it sounds awesome. will look into it.
