play sound only once on SetActive of GameObject

Question

hello, i have looked up and down and tried various scripts, but i cannot seem to get audio to play only once on each time the object is SetActive. i have tried variations of playOneShot etc, but cannot get it to play audio 'once' each time the object is setactive. The particular gameobject randomly switches SetActive true/false. i would like the audio to play once each time the gameobject is setactive.(true). Hope this makes sense, any leads would be greatly appreciated :)

Hrmmm, well, assuming that it isn't the audio itself you are having trouble with, and PlayOneShot is making a sound, you could put that audio function inside of the OnEnable() function. Anything inside of that function will happen once every time the object is enabled. There is also a OnDisable() function in case it is useful.

I put together a simple script that might help. Hope it makes sense, feel free to ask if youve got another question :)

EDIT: Just to clarify, this script can be attached to an empty gameobject, you then tell the script which gameobject(s) you want to activate/deactivate upon a certain condition.

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 
 public class SetActiveScript : MonoBehaviour {
 
     public GameObject objToActivate;
     AudioSource attachedAudioSource;
     
     void Start () {
         attachedAudioSource = objToActivate.GetComponent<AudioSource>();
     }
 
     void Update () {
         // on left mouse button (by default)
         if (Input.GetButtonDown("Fire1"))
         {
             // check if object is active and if audio is playing
             if (objToActivate.activeSelf && !attachedAudioSource.isPlaying)
             {
                 // deactivate object
                 objToActivate.SetActive(false);
             }
             // check if object is deactivated
             else if (!objToActivate.activeSelf)
             {
                 // activate object if it was deactivated
                 objToActivate.SetActive(true);
                 // make sure audiosource isnt playing already for some reason
                 if (!attachedAudioSource.isPlaying)
                 {
                     // make sure audio is not looping
                     attachedAudioSource.loop = false;
                     // play audiosource
                     attachedAudioSource.Play();
                 }                
             }
         }        
     }
 }
