NGUI 3 Support / ScrollView + UISlider problem

« on: March 12, 2014, 01:52:20 PM »

Hi,
I updated NGUI on monday to the last version 3.5.3 but I have a problem I hadn't before.
I have an unrestricted UIScrollview that is linked to an UISlider.

Every time I scroll the panel by touch or click I got this error:

NullReferenceException: Object reference not set to an instance of an object
UIScrollView.UpdateScrollbars (.UIScrollBar sb, Single contentMin, Single contentMax, Single contentSize, Single viewSize, Boolean inverted) (at Assets/NGUI/Scripts/Interaction/UIScrollView.cs:494)
UIScrollView.UpdateScrollbars (Boolean recalculateBounds) (at Assets/NGUI/Scripts/Interaction/UIScrollView.cs:441)
UIScrollView.MoveRelative (Vector3 relative) (at Assets/NGUI/Scripts/Interaction/UIScrollView.cs:632)
UIScrollView.MoveAbsolute (Vector3 absolute) (at Assets/NGUI/Scripts/Interaction/UIScrollView.cs:643)
UIScrollView.LateUpdate () (at Assets/NGUI/Scripts/Interaction/UIScrollView.cs:874)

If I don't touch the ScrollView but I slide the UISlider, it does nothing.

I attached the configuration of the UIScrollView and UISlider to the topic.

Thank you.

EDIT: I did more tests and I debugged the variable 'sb' of the line throwing NullRefException

1. Debug.Log ("HorizontalScrollBar:"+sb);

returns:

HorizontalScrollBar:

So the UIScrollbar seems to be NULL.
But when I debug it before the function call, it's not null...

EDIT2:
Little more test

1. Debug.Log ("ScrollBar:"+ (horizontalScrollBar as UIScrollBar));

returns null. You're casting the UIProgressBar to UIScrollBar but it's breaking it... Can I remove the cast without breaking all NGUI?

Are you sure one of your camera is not filming the content of the other?
Each camera should be set to film only one layer, and the layer of your two UI must be different two avoid one camera filming the other UI.
Don't know if I express myself correctly

I think his button is disable by default and he is "activating" it when the user is the host. So I think the button have an alpha of 0 at the start.

Hi,
We've done what you were saying and it's working fine now. It's a good lesson for the future, thank you for your advises.
Moreover, by moving the larger textures out, the app is using less memory.
Thank you !

Hi,
It's not very obvious here but the graphist made some specific things on some sprites that make them non "sliceable" (sorry I don't know if the word exists ^^ )
Same thing for the buttons with texts, if I didn't made a sliced sprite from the assets, the graphist give me, this is because the text, for example, have some effects that I can't reproduce with NGUI.
Anyway, could it be a good idea to split my atlas in two or more parts to prevent me from these Atlas Maker "WTF" problems? (I know by reading the forum that the problem is not from you but from something inside Unity that is fucking the textures during the build)

NGUI 3 Support / 4K Atlas constantly crashing on Add/Update

« on: February 27, 2014, 06:11:28 AM »

Hi,
I'm fighting with a 4K atlas for 2 days. It contains lots of sprites at the moment(114). Everytime I try to add a sprite, i get an error:

MissingReferenceException: The object of type 'Texture2D' has been destroyed but you are still trying to access it.
Your script should either check if it is null or you should not destroy the object.

I have this error very often, but everytime I just retry and it's okay(more or less, I have to build the atlas 2 sprites by 2 sprites and Commit on Git between each update if I don't want to redo it everytime...)
It's not a size problem, because it's doing it with every sprite I want to add since I have 114 sprites.
The proof that there is still space in the atlas is attached to the topic.

Thank you.

I'm integrating some things right now so I can't test immediately but if I don't touch the property after updating, it should not break my UI right?

I don't know what it can be. May be you should wait for an answer of the NGUI dev.

Which version of Unity are you using? Pro? Are you using pro stuff like RenderTexture or some things?

NGUI 3 Support / UIScrollView + FixedSize problem 3.5.0

« on: February 20, 2014, 05:23:46 AM »

Hi,
In the last updates you introduced ContentOrigin on UIScrollView.
Some weird thing is happening when the camera is set to FixedSize.
All my panels are f***ed when I'm using FixedSize. But the thing really weird is that when I change the ContentOrigin to another and then go back to the one I wanted, everything is fine.
For example, to test my UI in iPad Retina definition, I set the camera to FixedSize and the height to 1536. Before the update, everything was fine but now everything is broken.

Cordially,
Romain Pedra
