I have a main scene with 2 buttons, where each button should open other scene (button 1 => scene 1, button 2 = > scene 2) and in each of these scenes I have a back button that should go back to the main scene.

I manage to do that successfully but when I use a Coroutine so I can have a delay of 2 seconds while loading the next scene, I get the following error when I click “Back to main scene” button:

Coroutine couldn’t be started because the the game object ‘Scene Loader’ is inactive!
Here is my code:

> public class SceneLoader :
> MonoBehaviour {
> 
>     public void LoadNextScene(int numberOfScene)
>     {  
>         StartCoroutine(LoadAfterSeconds(numberOfScene));
> 
>     }
> 
>     private IEnumerator LoadAfterSeconds(int numberOfScene)
>     {
>             yield return new WaitForSeconds(2f);
> 
>             SceneManager.LoadScene(numberOfScene);
>     }
> 
> }

When I am in the main screen and I click on the button 1 or 2 to go to the other scenes it’s working as intended after 2 seconds, but when I click “Back to main scene” it doesn’t do anything and I get the error that the game object ‘Scene Loader’ is inactive!

I know I could use Invoke() but I would like to understand what I am doing wrong.

Any help is appreciated.

Thank you.

Probably you assign the prefab(asset) in onClick event and not the active instance of it you should have in the scene.

I suggest visiting Learn section and go through, at least, the basic tutorials, before trying moving further.
