Loading bar - async.progress not working?

Hi!

I'm trying to setup a simple loadingbar using async loading and using the progress value from the async load operation.

I've tried several ways of setting this up and after reading a bit about it I ended up with something like this:

Code (csharp):

1. AsyncOperation async = Application.LoadLevelAsync("0Menu");
2. Debug.Log("Start Loading);
3.  
4. while(!async.isDone)
5. {
6.      Debug.Log("loading...");
7.      progressbar.value = async.progress;
8.  
9.      yield return null;
10. }

So, I now get a few "loading.." printed out, but the async.progress always returns zero.

I start this as a coroutine in Start.

I read some places that the progress property might be broken? Is this true?
If so I guess I will have to stick to something that just animates a bit while the scene is loading.

Btw, I do have unity pro.

k.

 

in some parts its broken yes.

also that you have pro is clear, async loading is pro only

 

Yep, make sure you have pro.

 

Yes heh. Thats why i mentioned that i had pro. So that people wouldn't spend any effort telling me to get pro but ok. I can make a progress icon of sorts. Something that just animates.

I plan to do this by instantiating a prefab containing a backdrop and a progress bar (from excellent ez gui).
The i set it to do not destroy on load, load the scene async while animating something. Then when the scene is loaded i can have a "tap to continue" message displayed.

Anyway, at least i know that there are known bugs, so i can focus effort somewhere else

Thanks!

ever get this working ?
I have similar issue.. async loading appears be.... well... only partially async...
rendering seems to stop during async loading, then continues after loading.

Trying to just draw some regular moving gui textures... bouncing ball etc....
It prints 30 or so debug messages during the loading... but doesn't update the screen.

This is both on iOS-pro and Mac-pro unity
any ideas ?

 

Also experiencing identical issue.

 

Update:-
it is actually working, but strangely only on the device, not on PC or Mac.
maybe it just loads too fast on PC/Mac

 

yep, it was quite erratic on the mac, but worked ok on the iphone.

I just instantiate a loading screen where I have various controls.
I have an icon there which is automatically set to animate when it's created.
And this just runs while I load, and I remove it and wait for input when it's all done.
I get input, fade out the screen, and destroy the object afterwards.

Kindof rough but it seems to work ok..

Code (csharp):

1.  
2.  
3. public void InitLoadScreen(string screenToLoad, bool tap)
4.     {
5.         string textureToLoad = "Textures/LoadingScreens/" + screenToLoad;
6.         TextAsset locationDescription = (TextAsset)Resources.Load(("Textures/LoadingScreens/" + screenToLoad + "Desc"));
7.         backdrop.renderer.material.mainTexture = (Texture2D)Resources.Load(textureToLoad);
8.         descriptionText.Text = locationDescription.text;
9.         loadScreenPanel.Reveal();
10.         StartCoroutine(LoadLevel(screenToLoad, tap));
11.     }
12.    
13.  
14. IEnumerator LoadLevel(string screenToLoad, bool tap)
15.    {
16.       yield return new WaitForSeconds(1.0f);           // Wait until we did the fade out before we load.
17.       Debug.Log("Loading " + screenToLoad);
18.           async = Application.LoadLevelAsync(screenToLoad);
19.      
20.          while(!tapped)
21.          {
22.          if(async.isDone) // Level finished loading.
23.          {
24.             if(!tap)
25.                 tapped = true;
26.             animatedIcon.Hide(true);
27.             tapToContinue.controlIsEnabled = true; 
28.          }
29.            
30.          yield return null;
31.         }
32.        
33.        Destroy(this.gameObject, 1.0f);
34.        loadScreenPanel.Dismiss();
35.    }
