Need help with this error please

Unity Engine
1

I get the following error sometimes
I try to reproduce it through my game but it seems I don’t know exactly what causes it , as sometimes it happens and other time it doesn’t happen even though I do the same steps that made it happen

lol alot of “happen” words … . anyway

here is the main error label

ArgumentException : Getting control 0's position in a group with only 0 controls when doing Repaint
Aborting

about the error description , it is too large so it will be ugly to paste it here , so I will paste it in a text file and attatch it in the post if anyway can figure out the problem from it

I think it is something about my GUI’s functions , as I have alot of windows
but I rechecked every window ID and each window have its own unique one
and no more than 1 GUI.BringWindowToFront function call at the same time
and thats all I have thought about to figure it out and still I get this error sometimes

check the attatchements

It may be an issue with GUILayout.BeginHorizontal/BeginVertical that are not ended…

3

The only GUILayout expression I used so far is

        selectedGrid = GUILayout.SelectionGrid(selectedGrid, slots, 5, GUILayout.Height(secondWindowHeight));

and I didn’t use GUILayout.BeginHorizontal/BeginVertical at all
could this be the problem ?

I sux at GUI’s sry

4

Hm, do you use a GUILayoutUtility function, like GetLastRect or GetRect ?
It can only be done within a Repaint event type :

if(Event.current.type == EventType.Repaint)
m_lastRect = GUILayoutUtility.GetLastRect();

5

I think it’s a bug, i’ve been having it also but can’t reproduce it

6

Nope I don’t use any of these , I don’t even know what are those yet , I’m learning as I go

@ appels hmm… are you sure ? we need more ppl to confirm this then to send it to devs

by the way , I get all my windows and controls painted even though I get this message , so this message don’t affect my game or any GUI’s on it or thier functionality

will let you know if this happens after I build the game and it still not affect the game though I will not know if it happens and my game still works fine in the built

7

same here, gui draws everything, just get the error sometimes

8

What’s your slot var. Is it of type string[ ]/Texture[ ]/GUIContent[ ]? Maybe try a reimport so that it can compile the scripts properly.

9

the slot is a string[ ] so no import , but yeah you gave me an idea now as it is still null may be , the array have a length but none of its members have a value yet , it gets the values from the game progress , I’ll check that
thanks

10

Nope eventhough I set the values of the string array I still get the error
I get it more now , it seems this error happens on the first call for the gui after launching the game and never repeat again later

any clues yet ?

11

Yes. Set selected grid to -1 at the start.

var selectedGrid : int = -1;
12

Well I’ve set selectedGrid to -1 and I still getting the same error

well I got rid of this error by completely remove the GUILayout , I hate GUILayout and don’t know exactly how they work , reading the scripting reference and manual didn’t help much to figure it out completely so I used GUI and no errors at all

13

Maybe try the new version of Unity. Might have fixed that. :smile:

14

huh ? there is a new version ?
OMG they just released a new version now !!
ty

15

Yeap. 3.4 just got released last nite. According to my time. :smile: Have fun.

This happens when you call a Loop inbetween GUILayout.BeginScrollView. I’m actually getting it right now. Haven’t found any fixes as of yet.

scrollPosition = GUILayout.BeginScrollView(scrollPosition, GUILayout.Width(sX), GUILayout.Height(sY));
		
		for(int i = 0; i < PlayerData.instance.Skill.Length; i++)
		{
			GUILayout.Label ( PlayerData.instance.Skill[i].Name + ": "  + PlayerData.instance.Skill[i].CurrentSkill + "\tTil Gain: " + (int)PlayerData.instance.Skill[i].CurrentCount +" / " + (int)PlayerData.instance.Skill[i].gainNeeded() );
		}
		
		GUILayout.EndScrollView();

Edit** - I actually ending up working around mine since I was merly trying to extend the scrollbar as far as my skills needed to go. So I simply counted Enumerated Skills and multipled it by a line offset number.
