Question Audio Source dissapears when running play mode

When I try to run my game the Audio Source just dissapears while the GameObject is given before i start it.
I'm using Unity version 2020.3.4f1

Code (CSharp):

1.  
2. using System.Collections;
3. using System.Collections.Generic;
4. using UnityEngine;
5. using UnityEngine.SceneManagement;
6. using UnityEngine.UI;
7.  
8. public class MainMenu : MonoBehaviour
9. {
10.     public GameObject mainMenuUI;
11.     public GameObject settingsMenuUI;
12.     public GameObject soundsMenuUI;
13.     public Slider mainVolumeSlider;
14.     public Text mainVolumeText;
15.     public float volumeValue = 1f;
16.     public AudioSource OpeningSource;
17.  
18.     // Update is called once per frame
19.     void Start()
20.     {
21.         OpeningSource = GetComponent<AudioSource>();
22.     }
23.     public void Settings()
24.     {
25.         mainMenuUI.SetActive(false);
26.         settingsMenuUI.SetActive(true);
27.     }
28.     public void Sounds()
29.     {
30.         settingsMenuUI.SetActive(false);
31.         soundsMenuUI.SetActive(true);
32.     }
33.     public void Back()
34.     {
35.         settingsMenuUI.SetActive(false);
36.         mainMenuUI.SetActive(true);
37.     }
38.     public void MainChangeValue()
39.     {
40.         Debug.Log(mainVolumeSlider.value);
41.         volumeValue = mainVolumeSlider.value / 100;
42.         mainVolumeText.text = (volumeValue * 100).ToString() + "%";
43.         OpeningSource.volume = volumeValue;
44.     }
45.  
46. }
47.  
48.  
49.  

 

Line 21 contradicts how you are setting it up.

Either set it up in the editor as you show above, OR use GetComponent<T>() on the correct GameObject to find it.

Do not do both.

 

Thank you for your help it works again.
