play audio for few seconds on key hit

Question

Hello all. Not much of a coder but I'm trying to have a short audio clip play whenever the player presses spacebar.

Right now the player is able to jump by pressing spacebar and if they hold it down they continue to rise for about three seconds before they begin falling. I would like the audioclip to play for as long as they are rising, but currently it plays the entire audio file (about 27 seconds long). I understand that my current code doesn't tell it to stop, but I'm having a hard time figuring out how to play the audio, wait for three seconds, then stop and reset the audio.

my spacethrusters script (C#) is attached to my fps controller along with the audiosource component.

Any help at all would be great, here's the current code I have:

using UnityEngine; using System.Collections;

public class spacethrusters : MonoBehaviour {

 //Update is called once per frame
 void Update () {
     if (Input.GetKeyDown("space"))
         audio.Play ();
     }

}

Thanks again.

I suppose you have a variable, used to determine if the player is falling or not. If this variable is called falling, the code to stop the audioclip looks like this:

 if(Input.GetKeyUp("space") || (Input.GetKey("space") && falling == true && !audio.isPlaying))
 {
     audio.Stop();
 }

First statement Input.GetKeyUp("space") is used to stop the audioclip when player stops holding the spacebar.

Second statement Input.GetKey("space") && falling == true stops the audioclip when player begin falling, but still holds the spacebar.

!audio.isPlaying is there to ensure that the function won`t be called if the audioclip has been already stopped.

That looks perfect. How would I go about creating the 'falling' variable? I looked into some raycasting options but I got a bunch of errors. Sorry for my inexperience.

Simply create a boolean variable named falling

 var falling : boolean;

and set it to true after those 3 seconds.
