using UnityEngine.SceneManagement;
using UnityEngine.UI;
public class Loading : MonoBehaviour {
public GameObject loadingScreen;
public Slider slider;
public Text progressText;
public void LoadLevel (int sceneIndex)
{
StartCoroutine(LoadAsynchronously(sceneIndex));
}
IEnumerator LoadAsynchronously (int sceneIndex)
{
AsyncOperation operation = SceneManager.LoadSceneAsync(sceneIndex);
loadingScreen.SetActive(true);
while (!operation.isDone)
{
float progress = Mathf.Clamp01(operation.progress / .9f);
slider.value = progress;
progressText.text = progress * 100f + “%”;
yield return null;
}
}

the code looks good to me. I added some notes to help you understand. attach this script to an empty GameObject, not the button gameObject.
You need a few UI gameObjects in the scene. and you need to link the button with an OnClick() event
I added a wait for 5 sec.

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

public class Loading : MonoBehaviour
{

    public GameObject loadingScreen; //not sure what object this should attached to, the UI slider?,  by default it's not active, per line 22
    public Slider slider; //some UI slider Slider object
    public Text progressText; //some UI Text object

    public void LoadLevel (int sceneIndex) //the button uses this with the OnClick() Event, you send an int(the int is the scene number in unity "build settings") to this via the button
    {
        StartCoroutine(LoadAsynchronously(sceneIndex)); //this start a Coroutine
    }

    IEnumerator LoadAsynchronously (int sceneIndex)
    {
        yield return new WaitForSeconds(5); // a wait timer, wait for 5 sec befor we load the scene
       
        AsyncOperation operation = SceneManager.LoadSceneAsync(sceneIndex); 

        loadingScreen.SetActive(true); // active/enable the gameobject

        while (!operation.isDone)//if the scene is not complete it's load, then stay in the loop
        {
            float progress = Mathf.Clamp01(operation.progress / .9f);

            slider.value = progress; //move the UI slider bar
            progressText.text = progress * 100f + "%";

            yield return null;
        }
    }
}

Watch these video’s on UI buttons, they go over the OnClick() Event system

other then that, Do you have the loading scene? IE a scene that starts before the main menu scene. if not you need to create one. that scene can then enable the UI loading bar stuff.

use a script to auto load the main menu

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

public class LoadingScene : MonoBehaviour
{

    public GameObject loadingScreen;
    public Slider slider;
    public Text progressText;
   
    public int loadSceneIndex = 1; //what ever the scene number is
   
    void Start() {
        StartCoroutine(LoadAsynchronously(loadSceneIndex));
    }


    IEnumerator LoadAsynchronously (int sceneIndex)
    {
        yield return new WaitForSeconds(5);
       
        AsyncOperation operation = SceneManager.LoadSceneAsync(sceneIndex); 

        loadingScreen.SetActive(true);

        while (!operation.isDone)
        {
            float progress = Mathf.Clamp01(operation.progress / .9f);

            slider.value = progress; //move the UI slider bar
            progressText.text = progress * 100f + "%";

            yield return null;
        }
    }
}

U dont understand me.This script go over OnClick() system, I dont want that .I want to autostart that script. (This script is loading script| When I start my game i want to first scene is loading scene to scene 2 (MainMenu) i dont want to click button to start loading I want to autostart this script…)Thank for everything!

The script posted above does not use OnClick(), it “autostarts” on Start()

7

Now it work, last time this script dont work when I use it, sorry and thanks. :slight_smile: And how i can set a WaitForSeconds(5) to 0.5 or 0.1 when i set it there is error and sorry one more time…

8

WaitForSeconds(0.1F)

9

I always us a small f not a capital F
WaitForSeconds(0.1f) // a tenth of a sec
or
WaitForSeconds(0.5f) // half a sec

10

Thanks…:slight_smile:

11

any idea how to replace the UI button with script?
Like, I wanna Input.GetKeyDown(KeyCode.F) and it will start the IEnumerator?

Yeah its work… thanks for your solution
