Exception because of null texture in CursorIcon

circlesmiler

Hello Chris,

not sure if it's a bug, as I updated my project on the latest LTS Unity version and the latest Adventure Creator, I'm seeing an error message in the console:

null texture passed to GUI.DrawTexture
UnityEngine.GUI:DrawTexture (UnityEngine.Rect,UnityEngine.Texture,UnityEngine.ScaleMode,bool,single)
AC.CursorIconBase:Draw (UnityEngine.Vector2,bool) (at Assets/AdventureCreator/Scripts/Menu/Menu classes/CursorIcon.cs:666)
AC.Hotspot:DrawHotspotIcon (bool) (at Assets/AdventureCreator/Scripts/Logic/Hotspot.cs:424)
AC.StateHandler:_OnGUI () (at Assets/AdventureCreator/Scripts/Game engine/StateHandler.cs:434)
AC.StateHandler:OnGUI () (at Assets/AdventureCreator/Scripts/Game engine/StateHandler.cs:383)
UnityEngine.GUIUtility:ProcessEvent (int,intptr,bool&) (at /Users/bokken/build/output/unity/unity/Modules/IMGUI/GUIUtility.cs:190)

I could fix it by adding:

      if (texture == null) {
        return null;
      }

to CursorIcon.cs#614.

I'm using a custom cursor, but no special Hotspot cursor:

I think I found the configuration problem on my side:

But should it result in a null pointer exception? Maybe, not... ¯_(ツ)_/¯

Recreated, thanks for the details.

That's the issue, indeed - I'll see if an amendment to improve error feedback can be made.
