Unity 2017.1.p2 Issue with GUIUtility.hotControl

Unity Engine
1

It looks like there is an error happening sometimes when setting the hotControl.

Should not be capturing when there is a hotcontrol
UnityEngine.GUIUtility:set_hotControl(Int32)
CreativeSpore.SuperTilemapEditor.TilemapEditor:smile:oPaintSceneGUI() (at Assets/CreativeSpore/SuperTilemapEditor/Scripts/Tilemap/Editor/TilemapEditor.cs:669)
CreativeSpore.SuperTilemapEditor.TilemapEditor:OnSceneGUI() (at Assets/CreativeSpore/SuperTilemapEditor/Scripts/Tilemap/Editor/TilemapEditor.cs:285)
UnityEngine.GUIUtility:processEvent(Int32, IntPtr)

I couldnā€™t find any information about this error. Is it a bug?

This line is triggering the error:

GUIUtility.hotControl = controlID;

And this is called before:

int controlID = GUIUtility.GetControlID(FocusType.Passive);
HandleUtility.AddDefaultControl(controlID);
EventType currentEventType = Event.current.GetTypeForControl(controlID);

Thanks for your help!

Unity 2017 is riddled with bugs such as these. Having the same issues, +1.

yeah, me tooā€¦ working on a custom inspector with toolbars as tabsā€¦ at least a line would help to find a workaroundā€¦

Getting similar weird errors. In my case not pointing to a specific line (sometimes):

Should not grab hot control with an active capture (current=Dockarea3 (x:0.00, y:0.00, width:1501.00, height:353.00) global rect: (x:0.00, y:0.00, width:1501.00, height:353.00) new=Dockarea5 (x:0.00, y:0.00, width:223.00, height:573.00) global rect: (x:0.00, y:0.00, width:223.00, height:573.00)
UnityEngine.GUIUtility:processEvent(Int32, IntPtr)

Should not be capturing when there is a hotcontrol
UnityEngine.GUIUtility:processEvent(Int32, IntPtr)

I am in 2017.1.1f. Once I saw this message (the second one) pointing to one slider, and once to a button, but I canā€™t reproduce it anymore. Iā€™m upgrading to see if the weird errors go awayā€¦

While writing this now I got a:

GUI Error: You are pushing more GUIClips than you are popping. Make sure they are balanced)
UnityEngine.GUIUtility:processEvent(Int32, IntPtr)

Lots of errors guys :frowning:

EDIT. Version 2017.2.0f3 solved the issues for me.
EDIT2. I still get random

Should not be capturing when there is a hotcontrol
UnityEngine.GUIUtility:processEvent(Int32, IntPtr)

Iā€™m not even using GUIUtility.hotControl anywhere in my code. And given it is difficult to reproduce I donā€™t know how could I log a bug for this.

Iā€™m also hitting this a lot. @karl_jones , are you still waiting for someone to file a bug on this?

10

We have some similar sounding bugs with QA but its still worth filing your own bug report especially if its an issue for you.

@karl_jones Got a similar bug in 2017.2 when simply selecting multiple particle systems in hierarchy/inspector which have been upgraded from older versions. (Case 972613)

SetMinMaxState is not allowed with multiple different values
UnityEngine.GUIUtility:ProcessEvent(Int32, IntPtr)

Same issue with completely new project in 2017.3 - Happens occassionally, next time I got it Iā€™ll send a bug report (Done: Case 980251)

Still there as well, so much for filing bug reportsā€¦

[Log] [C:/buildslave/unity/build/Runtime/UIElements/Managed/EventDispatcher.cs] Should not be capturing when there is a hotcontrol

No line number, no info on what caused it, just appeared all of the sudden. Lame sauceā€¦

14

Iā€™m getting this as well.

Anyone getting this while using OnSceneGUI events for anything mouse-related?

@karl_jones

Any update on this bug?

15

It was fixed in March. What version are you using?

16

Awesome! ā€“ could you link me to the bug case for this please?

I am currently developing an Asset (working on the 2017.1 version) and I want to be sure I can quote this if there are any issues from customers on any of these versions (plus I want to know where it originated because I want to be sure there is nothing wrong with my code, and find a way to workaround it if possible).

Thanks for the quick response, karl!

@karl_jones Same thing for me using 2018.2.16f1:

The message pops up from time to time; I have no idea what I was doing that triggered it.
