Question Flappy sfx

Hi! So I'm trying to make a flappy bird game and I want a sound effect to play when I die.

This was my function for dying (this is in the logic script):

Code (CSharp):

1. public void gameOver()
2.     {
3.         gameOverScreen.SetActive(true);
4.     }

So I went and added an Audio Source component in my logic game object and placed my mp3 file "NEILSCREECH". So I called it on the logic script:

Code (CSharp):

1.  public AudioSource NEILSCREECH;

and changed the function a bit:

Code (CSharp):

1. public void gameOver()
2.     {
3.         gameOverScreen.SetActive(true);
4.         NEILSCREECH.Play();
5.        
6.     }

So I ran the game and when I hit something that would kill me, it wouldn't play anything. It just gave the error code:
ArgumentNullException: Value cannot be null. Parameter name: source

Also, I found that if the play on awake setting on the Audio Source component is turned on, it would play, but it would still error on the pipes. How can I fix this?

 

It's always the same, always!!

How to fix a NullReferenceException error

https://forum.unity.com/threads/how-to-fix-a-nullreferenceexception-error.1230297/

Three steps to success:
- Identify what is null <-- any other action taken before this step is WASTED TIME
- Identify why it is null
- Fix that

 

LOL ok it's a dumb mistake but there was a step I didn't know (to drag the audio source component to the slot on the script). Thank you!
