Enter Play Mode error 'Cannot set the parent of TMP UI SubObject'

Open lolomap opened this issue 10 months ago • 14 comments

When I enter play mode, I have error: Cannot set the parent of the GameObject 'TMP UI SubObject [(HERE IS NAME OF MY FONT) + LiberationSans SDF Atlas]' while activating or deactivating the parent GameObject 'HERE IS NAME OF MY TMP_TEXT GAMEOBJECT'. It happens even I disable 'Animate On Start'

To Reproduce Steps to reproduce the behavior:

  1. Create TMP Text object on Canvas
  2. Set some font. I used cyrillic one.
  3. Add TMP Animator
  4. Enter Play Mode
  5. See error

I realised that my font doesn't have "<>" characters, so it generates submesh object automatically and it cannot be handled with TMPEffects. Anyway, I think such behaviour should be handled, right?

Have you made sure it works fine without the TMPAnimator component? Also can you give me the full callstack of the error?

It works fine for simple TMPText without TMPAnimator. I migrated to Unity 6 to check if it has same problem and the error changed a little bit:

Hmmm I see. IIRC I didnt have this problem with sprite animations which also create submeshes. Can you share your project files? If you dont want to do that, just the font asset and the contents of "<style=ANR>" should be enough

Luca3317 avatar Mar 04 '25 12:03 Luca3317

Трафарет ГОСТ 14192- 96 SDF.zip This is my font asset. Style tags: <color=#A3C2A3><link="ANR"><wave>

Couldnt repro the issue, seems to work fine for me

Tested in 6 and 2022.3.20 which is the closest version to yours ive had installed. Are you enabling/disabling some related gameobjects from another script?

Also make sure that maybe the font asset isnt just broken. Ive had to create a new one from the .ttf because the asset itself had missing references

Luca3317 avatar Mar 08 '25 17:03 Luca3317

I don't enable/disable related objects but change text content from script

lolomap avatar Mar 10 '25 13:03 lolomap

Can you send me your project files?

Luca3317 avatar Mar 10 '25 13:03 Luca3317

This is my project files: https://drive.google.com/file/d/1jLyuIOjozHmnZ0FkG8-Uqn6vvURKXQUH/view?usp=sharing I tried to recreate asset from .ttf and set new one but I still have this error

lolomap avatar Mar 10 '25 13:03 lolomap

Cool, will take a look later today

Luca3317 avatar Mar 10 '25 13:03 Luca3317

Oof totally forgot about this sorry. Will take a look next chance I get.

Luca3317 avatar Mar 28 '25 12:03 Luca3317

Hey so Id probably have some time over the weekend to check this out. I just took a quick look at the project and two things:

  • Is there some specific scene I should take a look at? It opens on an empty untitled one
  • The font you sent is not present in the project.

It would be best if you set up the scene in the way that causes the issue for you, so I can quickly repro and get to fixing the issue

Luca3317 avatar Apr 04 '25 12:04 Luca3317

There should be "Game" scene in a Assets/Scenes folder and the font should be the only one in Assets/Fonts. I renamed it to GOSTFont to avoid non-english characters. It is used on a scene in visible EventDescription object (Canvas/GamePanel/BottomPanel/EventInfo/DesctiprionScroll/Viewport/EventDescription/Content/EventDescription). Try to run and stop scene several times to get the error
