I was evaluating the free version of NGUI to see if it would work for my project.
I was specifically looking at it to handle the scrolling help section which has a lot of text.
All of the panel items disappear when I added 40 items each containing a lot of text.
The outlines of everything is still there, just the content disappears.
NOTE: Please let me know if this does not occur with the current/commercial version of NGUI.
It is easy to duplicate. Here are my exact steps:
Create a new project and import the free version of NGUI.
Open up Example 8 - Scroll View (Camera)
In the Inspector for View UI -> Anchor -> Offset, change the Columns to 1.
Under View UI -> Anchor -> Offset -> remove all of the Items EXCEPT one.
Delete the second UILabel item (the green 'New!' text), the UISlicedSprite and the UISprite.
Change the text in the (now) second UILabel from "12,345 Gold" to (without the quotes):
"Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text "
Change the Line Width of this UILabel to 650.
Adjust the position of this UILabel to fit underneath the other one and within the window.
Duplicate the Item 39 more times, watching the Game View as you do this. You will see when the text will disappear. Now, if you start deleting text within one of UILabels, at some point you will see the text reappear in the Game View.
I can send you my project zipped up if you like, please let me know.
I'm not sure if this is a bug or a limitation of NGUI or Unity.
If it is either a bug or limitation, please let me know if there is a workaround because I believe that NGUI will be a great tool for my project and I will buy it but only if I can get this part working.
Thank you,
Dave
