Having trouble getting sound to play on enemy death

Unity Engine
,

I have most of the enemy script done and working. If its health reaches zero the DIE function runs and the gameobject is destroyed while a death effect plays for one second. I am brain-farting on the part where I add an audio source to this part.

I have a variable to hold the audio source

    public AudioSource SoundToPlay;

I am grabbing it in Start

SoundToPlay = GetComponent<AudioSource>();

And where I trigger the die function I have it set to play

        health -= damage;
        if(health <= 0)
        {
            Die();
            SoundToPlay.Play();

Yet it wont play. I have the slots filled in the inspector. I tried placing the audiosrouce component on the enemy and then the camera. I can play the sound file just fine from the asset itself but it just wont play when the enemy dies.
Here is the entire script if this helps

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

public class Enemy : MonoBehaviour {

    public float speed;
    public float rotSpeed;
    public float shootingRange;
    public float retreatRange;
    public int health = 100;
    public GameObject deathFX;
    public AudioSource SoundToPlay;

    public float timeBtwShots;
    public float startTimeBtwShots;
    public GameObject projectile;

    public Transform firePoint;
    public Transform player;


    // Use this for initialization
    void Start ()
    {
        player = GameObject.FindGameObjectWithTag("Player").transform;
        timeBtwShots = startTimeBtwShots;
        SoundToPlay = GetComponent<AudioSource>();
    }
 
    // Update is called once per frame
    void Update ()
    {
        RotateTowards(player.position);

        if (Vector2.Distance(transform.position, player.position) > shootingRange)
        {
            transform.position = Vector2.MoveTowards(transform.position, player.position, speed * Time.deltaTime);
        }
        else if(Vector2.Distance(transform.position, player.position) < shootingRange && Vector2.Distance(transform.position, player.position) > retreatRange)
        {
            transform.position = this.transform.position;
        }
        else if(Vector2.Distance(transform.position, player.position) < retreatRange)
        {
            transform.position = Vector2.MoveTowards(transform.position, player.position, -speed * Time.deltaTime);
        }

        if(timeBtwShots <= 0)
        {
            Instantiate(projectile, firePoint.position, transform.rotation);
            timeBtwShots = startTimeBtwShots;
        }
        else
        {
            timeBtwShots -= Time.deltaTime;
        }
    }

    private void RotateTowards(Vector2 target)
    {
        Vector2 direction = (target - (Vector2)transform.position).normalized;
        var angle = Mathf.Atan2(direction.y, direction.x) * Mathf.Rad2Deg;
        var offset = -90f;
        transform.rotation = Quaternion.Euler(Vector3.forward * (angle + offset));
    }

    public void TakeDamage(int damage)
    {
        health -= damage;
        if(health <= 0)
        {
            Die();
            SoundToPlay.Play();
        }
    }

    void Die()
    {
        GameObject deathMarker = Instantiate(deathFX, transform.position, Quaternion.identity);
        Destroy(gameObject);
        Destroy(deathMarker, 1f);
    }
}

In your “Die()” function,
you gameObject gets Destroyed too fast , he get no chance to play the Sound,

put a delay on that or play the Sound before you destroy the gameObject itseflf

    public void TakeDamage(int damage)
    {
        health -= damage;
        if(health <= 0)
        {
            SoundToPlay.Play();
            Die();
        }
    }

small edit: I also believe that your Sound will get aborted at the moment of getting destroyed, that means, your gameObject with the Sound Component gets destroyed which means = No Sound gets played until the end

Thanks, I was just wondering about that. Maybe I will have the sprite replaced and play the sound then have the body destroyed a few seconds later.
Thanks again!

Just a small note, I recommend placing the SoundToPlay.Play(); inside the Die() method before destroying the object, like this:

    void Die()
    {
        SoundToPlay.Play();
        GameObject deathMarker = Instantiate(deathFX, transform.position, Quaternion.identity);
        Destroy(gameObject);
        Destroy(deathMarker, 1f);
    }

So if for any reason you need to call the Die () function from another script or anything the enemies still make a dying sound. This is worth for any type of method that you have multiple things happening at once, so that it’s more organized and it’s not possible to do a “partial method”.
