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:

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

public class MapArea : MonoBehaviour
{
    [SerializeField] List<Tricimal> untamedTricimals;
    [SerializeField] AudioSource townClip;

    public void PlayAudioClip()
    {
        townClip.Play();
    }

    public Tricimal GetRandomWildTricimal()
    {
        var untamedTricimal =  untamedTricimals[Random.Range(0, untamedTricimals.Count)];
        untamedTricimal.Init();
        return untamedTricimal;
    }
}

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.
