Title: Error with s_GetSizeOfMainGameView.Invoke in 5.4.0b9
Post by: col000r on March 11, 2016, 08:27:09 AM

Getting this error in the latest beta (5.4.0b9):

1. NullReferenceException: Object reference not set to an instance of an object
2. NGUITools.get_screenSize () (at Assets/NGUI/Scripts/Internal/NGUITools.cs:1871)
3. UIPanel.GetViewSize () (at Assets/NGUI/Scripts/UI/UIPanel.cs:1871)
4. UIPanel.UpdateTransformMatrix () (at Assets/NGUI/Scripts/UI/UIPanel.cs:1068)
5. UIPanel.UpdateSelf () (at Assets/NGUI/Scripts/UI/UIPanel.cs:1265)
6. UIPanel.LateUpdate () (at Assets/NGUI/Scripts/UI/UIPanel.cs:1228)

and that points me to:

1. mGameSize = (Vector2)s_GetSizeOfMainGameView.Invoke(null, null);

I see you're using reflection there to call some unity code. Did they change or rename that function?
Can you fix this please?

It's been fixed in NGUI pro for weeks now, and Unity actually re-added the function on their end in order to accomodate those that are not able to update NGUI due to being midway through a project.

In short, already fixed, you'll see it in the next update.

1.         static public Vector2 screenSize
2.         {
3.                 get
4.                 {
5.                         int frame = Time.frameCount;
6.  
7.                         if (mSizeFrame != frame || !Application.isPlaying)
8.                         {
9.                                 mSizeFrame = frame;
10.  
11.                                 if (s_GetSizeOfMainGameView == null)
12.                                 {
13.                                         System.Type type = System.Type.GetType("UnityEditor.GameView,UnityEditor");
14.  
15.                                         // Pre-Unity 5.4
16.                                         s_GetSizeOfMainGameView = type.GetMethod("GetSizeOfMainGameView",

33.                                 else mGameSize = new Vector2(Screen.width, Screen.height);

35.                         return mGameSize;
