Question PlayOnCollision

Hi,
I can't start the audio when entering an area in 2D.

I have a game object and here is the code attached to it. However, I can't attach the sound to the script on the Unity Inspector panel, or is there another way to do it? Thank you so much...

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5.  
6. public class PlayOnCollision : MonoBehaviour
7. {
8.     public AudioSource audioSource;
9.  
10.     void OnTriggerEnter(Collider other)
11.     {
12.         if (other.tag == "Player" && !audioSource.isPlaying)
13.         {
14.             audioSource.Play();
15.         }
16.     }
17. }
18.  
19.  

 

then, I've tried this and didn't work...

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public class Audio : MonoBehaviour
6. {
7.  
8. public AudioSource onesynthesize;
9.     // Start is called before the first frame update
10.     void Start() {
11.         onesynthesize = GetComponent<AudioSource> ();
12.        
13.     }
14.  
15.     // Update is called once per frame
16.     void Update() {
17.     }
18.         void OnCollisionEnter (Collision collision) {
19.            
20.             if (collision.gameObject.tag == "soundtileone"){
21.              onesynthesize.Play ();
22.            
23.             }
24.     }
25. }
