Scene not loading second time round

Unity Engine
1

Hi there,

I have three scenes at the following indexes
0 - Main Menu: Features a “New Game” button and a “Quit” button.
1 - Loading: Progress bar with async operation to load the third scene
2 - Game: Procedural city generator

The first time I go through the process of clicking “New Game”, the loading screen works really nicely. If I then return to the main menu using the in-game pause menu and click “New Game” again, the loading screen appears but nothing else happens.

I have absolutely no idea what to do, and although other people have had this issue, I cannot get any of the suggested fixes to work.

Here’s my code for the scene loading class:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.SceneManagement;
using UnityEngine.UI;

public class SceneLoading : MonoBehaviour
{
    [SerializeField] private Image progressBar;

    // Start is called before the first frame update
    void Start()
    {
        StartCoroutine(DelayLoading());
    }

    IEnumerator DelayLoading()
    {
        yield return new WaitForSeconds(1.0f);

        StartCoroutine(LoadGameScene());
    }

    IEnumerator LoadGameScene()
    {
        yield return null;

        // Begin scene loading
        AsyncOperation asyncOperation = SceneManager.LoadSceneAsync(2);

        // Prevent automatic scene activation
        asyncOperation.allowSceneActivation = false;

        // Whilst loading, update debug output and progress bar
        while (!asyncOperation.isDone)
        {
            // Output the progress to the console
            Debug.Log("[SceneLoading] Loading: " + (asyncOperation.progress * 100) + "%");

            // Progress bar fill == async operation
            progressBar.fillAmount = asyncOperation.progress;

            // Check if the loading has finished
            if (asyncOperation.progress >= 0.9f)
            {
                // Enable automatic scene activation
                asyncOperation.allowSceneActivation = true;
            }

            yield return null;
        }
    }
}

Hi,
I suggest you just start debugging your code? :slight_smile:
Print out values after every line if needed, until you get an overall picture what’s happening. If it works the first time.
But I assume you probably have something like dontdestroy code or singletons you’ve built that don’t get properly reset for the new game.
