NullReferenceException after updating Unity

Questions & Answers
1

Hey guys!
I just updated Unity and tried to play game in editor but it gives me this error: NullReferenceException: Object reference not set to an instance of an object
UILoadScreen.Update () (at Assets/Scripts/MainMenu/UILoadScreen.cs:24)

I’ve tried to fix this but no luck.

Scripts:

UILoadScreen

using UnityEngine;
using UnityEngine.UI;

public class UILoadScreen : MonoBehaviour {

	public GameObject loadScreen;
	public Slider loadingBar;
	public Text loadPercent;

	public float percentage;

	LoadNewScene scene;

	void Start () {
		scene = FindObjectOfType<LoadNewScene> ();
	}

	void Update () {

		if (scene.loading) {
			loadScreen.SetActive (true);
		}

		loadingBar.value = scene.aSync.progress;
		percentage = scene.aSync.progress / loadingBar.maxValue * 100;
		loadPercent.text = percentage.ToString ("F0") + "%";

		if (scene.aSync.isDone) {
			loadScreen.SetActive (false);
		}
	}
}

LoadNewScene

using UnityEngine;
using UnityEngine.SceneManagement;

public class LoadNewScene : MonoBehaviour {

	public string sceneName;

	public AsyncOperation aSync;

	[HideInInspector]
	public bool loading;

	public void LoadScene () {

		aSync = SceneManager.LoadSceneAsync (sceneName);
		loading = true;
	}
}

Can someone help? :frowning:

scene.aSync is null if you don’t call LoadScene. So those lines would cause a NullReference exception:

loadingBar.value = scene.aSync.progress;

percentage = scene.aSync.progress / loadingBar.maxValue * 100;

if (scene.aSync.isDone) {

Each of those lines try to access something from the aSync object.
