Audio Unity Error : ArgumentNullException: Value cannot be null

Hi. I'm creating a game that includes triggering audio when the player collides with a certain map, but unity gave me an error saying "ArgumentNullException: Value cannot be null". Two things. Well, one I've got no clue what this even means, and two how do I fix it? It tells me that it's on line 12. Here is my code:

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public class MapArea : MonoBehaviour
6. {
7.     [SerializeField] List<Tricimal> untamedTricimals;
8.     [SerializeField] AudioSource townClip;
9.  
10.     public void PlayAudioClip()
11.     {
12.         townClip.Play();
13.     }
14.  
15.     public Tricimal GetRandomWildTricimal()
16.     {
17.         var untamedTricimal =  untamedTricimals[Random.Range(0, untamedTricimals.Count)];
18.         untamedTricimal.Init();
19.         return untamedTricimal;
20.     }
21. }
22.  

 

You haven't assigned your "townClip" property in the inspector.

 

ArgumentNullException occurs because you tried to access a method from the AudioSource

townClip

but

townClip

is null. To fix it, you have to make sure there's an AudioSource assigned to

townClip

. In your case, just assign it in the inspector.

If it helps, here's an example.
