How do I play a sound when pressing the W key, and when I stop pressing the W key, the sound stops?

Question

I'm trying to play a sound when a vehicle is moving, so when I press the W key, it moves, and it plays the sound. But as soon as I release the W key, the sound continues to play, it doesn't stop instantly. I'd like for it to play an Idle sound when the vehicle isn't moving, an Shifting sound when W is pressed, and Reversing sound when the car is going backwards (not if S is pressed to slow the car down) and a braking sound when Spacebar is pressed. Plus, for all of these (Minus the Spacebar/brake) I would like it to play an decelerating sound when these keys aren't being pressed. Is this possible? If so, what is the code? How do I fix the W sound?? Please Help!

Script:

using System.Collections; using System.Collections.Generic; using UnityEngine;

public class PlayonW : MonoBehaviour {

 public AudioSource someSound;

 // Use this for initialization
 void Start () {
     
 }
 
 // Update is called once per frame
 void Update () {

     if (Input.GetKeyDown(KeyCode.W)) {
         someSound.Play();
         
         

         if (Input.GetKeyUp(KeyCode.W)) {
             someSound.Stop();
         }

     }
 }

}

You should put your braces correctly for your script to work. Also, don't call Play each frame if the audio source is already playing:

 using System.Collections; 
 using System.Collections.Generic; 
 using UnityEngine;
 
 public class PlayonW : MonoBehaviour {
 
  public AudioSource someSound;
  // Use this for initialization
  void Start () {
      
  }
  
  // Update is called once per frame
  void Update () {
         if (Input.GetKeyDown(KeyCode.W)) {
             if(!someSound.isPlaying) {
                 someSound.Play();
             }
         }
      
         if (Input.GetKeyUp(KeyCode.W)) {
             someSound.Stop();
         }
     }
 }

To your other question: Either have different Audio Sources for your each move set (move forward, reverse, break etc.) and play / stop them like this code, or have different clips and change the clip and see what clip is playing to play stop it at specific key presses.

I'm not sure what you're trying to achieve, if you want different sound for each key, you can use this and replicate. If you want to use the same sound for all kind of inputs, you can use Input.anyKey.

public AudioSource audioSource;

// Use this for initialization

void Start () { audioSource = GetComponent(); }

// Update is called once per frame

void Update () { if (Input.GetKeyDown(KeyCode.W)) { audioSource.Play(); }

      if (Input.GetKeyUp(KeyCode.W)) 
     {
          audioSource.Stop();
      }

}
