Title: Changing UISprite atlas makes inspector blank, errors
Post by: PaulGregory on November 29, 2013, 05:34:00 AM
I'm using 3.0.6f6, and switching the UISlicedSprite on a load of buttons that were created with the SciFi Atlas to use my own imagery from my own Atlas.

I can change about 4 or 5 at a time before things start going wrong.

Upon changing the Atlas in the inspector, the inspector changes to be almost blanked out - just a small rectangle at the top left.

This error pops up in the console (4 times every time I return to Unity):

  1. NullReferenceException: Object reference not set to an instance of an object
  2. NGUIEditorTools.DrawSprite (UnityEngine.Texture2D tex, Rect drawRect, .UISpriteData sprite, Color color, UnityEngine.Material mat) (at Assets/NGUI/Scripts/Editor/NGUIEditorTools.cs:705)

If I select another thing in the Hierarchy I get these errors:

  1. The serializedObject should not be used inside OnSceneGUI or OnPreviewGUI. Use the target property directly instead.
  2. UnityEditor.GameObjectInspector:OnEnable()
  3.  
  4. The targets array should not be used inside OnSceneGUI or OnPreviewGUI. Use the single target property instead.
  5. UnityEditor.GameObjectInspector:OnEnable()

If I press Play and Stop, everything sorts itself out and I can continue changing the UISprite.

I'm on a Mac, and these are sprites that had been added with earlier versions of NGUI (3.0.x) if that makes any difference.

After a Play and Stop restart I can do 4 or 5 as I say but then the next one starts going mad.

This is rather annoying.

UISlicedSprite has been removed back in 3.0.0, and has been only left for backwards compatibility in the upgrade package. Did you run the upgrade tool to auto-upgrade all of them to normal sprites set to sliced mode?

I did not use NGUI before 3.0.something so I have had no need of the upgrade package. I could do with one from 3.0.5 to 3.0.6 though!

The component *is* a UISprite with the sprite mode set to sliced. The object has the name/label UISlicedSprite, probably from the sample stuff.

Having ploughed through with it (as there is a workaround of play/stop), I can say that sometimes I got the error straight away (ie first sprite, not 4th or 5th).

Curious. Well, on line 701 of the same file (NGUIEditorTools) there is a check:
  1. if (!tex) return;
Change it to:
  1. if (!tex || sprite == null) return;
