hello everyone,
i made a scene with th following components:
the canvas contains a
-imagebackground
-button (which i want to replace to: press enter of f (something like that)
-imagebackground2 (which appears when i press the button.)
-slider. (loading bar)(appears when pressed the button)
-loadingtext (appears when pressed the button)
i attached the script below to the button.
(the right way)
what i want: a scene with a loading screen.
once i press the button. a load bar should appear.
a text “loading…” should appear.
what is the reason it isnt working? i get an error(below↓)
here is the script
using UnityEngine;
using System.Collections;
using UnityEngine.UI;
using UnityEngine.SceneManagement;
public class loadingbar : MonoBehaviour {
AsyncOperation ao;
public GameObject LoadingScreenBG;
public Slider progBar;
public Text loadingtext;
public bool isFakeLoadingbar = false;
public float fakeIncrement = 0f;
public float fakeTiming = 0f;
// Use this for initialization
void Start () {
}
// Update is called once per frame
void Update () {
}
public void LoadLevelammp()
{
LoadingScreenBG.SetActive(true);
progBar.gameObject.SetActive(true);
loadingtext.gameObject.SetActive(true);
loadingtext.text = "loading...";
if (!isFakeLoadingbar)
{
StartCoroutine(LoadLevelWithRealProgress());
}
else
{
}
}
IEnumerator LoadLevelWithRealProgress()
{
yield return new WaitForSeconds(1);
ao = SceneManager.LoadSceneAsync(1);
ao.allowSceneActivation = false;
while (!ao.isDone)
{
progBar.value = ao.progress;
if(ao.progress == 0.9f)
{
loadingtext.text = "press start to continue";
if (Input.GetKeyDown(KeyCode.Joystick1Button7))
{
ao.allowSceneActivation = true;
}
}
Debug.Log(ao.progress);
yield return null;
}
}
}
now im getting the error:
NullReferenceException: Object reference not set to an instance of an object
loadingbar+c__Iterator0.MoveNext () (at Assets/loadingbar.cs:50)
UnityEngine.SetupCoroutine.InvokeMoveNext (IEnumerator enumerator, IntPtr returnValueAddress) (at C:/buildslave/unity/build/Runtime/Export/Coroutines.cs:17)
hope someone could help me
