TextMeshPro 1.4.0 : ArgumentOutOfRangeException when using emotes sprites assets

Hi, I have an error on some texts with emotes sprites assets.
Here is the error stack trace:

ArgumentOutOfRangeException: Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index

I'll need more details on how to reproduce these errors.

Can you provide a simple repro project or scene for me to look at?

 

OK here is the link for the repro project on google drive: https://drive.google.com/file/d/1gRXMyZShKQG88IPexQJN3dNkEoeUKZSD/view?usp=sharing

As you can see I have some dynamic fallback font assets in my project (maybe this is what is casing the issue).

I added a script on the Main Camera with 3 buttons: SetText1, SetText2 and ClearTexts.
To reproduce the bug, just launch the scene (Play) then hit SetText2, ClearTexts, SetText2 and then you will see the error.
Only the second text is causing problems, If you try with SetText1 no error occurs.

 

Thanks for providing the repro project. I'll take a look tomorrow when I wake up.

 

Make the following changes in the TMPro_Private.cs at line 1125 and 1181 as well as in TMPro_UGUI_Private.cs at line 1195 and 1251.

Code (csharp):

1.  
2. // Replace m_spriteIndex by spriteIndex
3. m_textInfo.characterInfo[m_totalCharacterCount].textElement = spriteAsset.spriteCharacterTable[spriteIndex];

Not sure how I missed this in the first place. Thank you for having taken the time to report the issue and to provide the repro case which made identifying this simple.

 

Thanks to you to correct it so fast

 

This is still showing up in 2.01, but the fix mentioned above thankfully works well.

[Edit]
Unfortunately it looks like this patch is automatically reset at times and I have to update it again before building for the store.

 

Yeah, I have a same error (2.0.1). When it will be fixed?

 

Can you test with the latest release which is version 2.1.0-preview.1?

 

Seems it works with preview version.. Will do more tests.
BTW, when will be emoji support with modificators? Like flags, skin color, etc

 

Yes, the preview version fixes it. Thank you.
