Assert Failed Error. Help?

[MrJane]

I’m working on a custom class. I have the idle animation at the character sheet working, as well as the skills and camping done (at least they appear fine in the character sheet). I add the class to my party and embark to a dungeon. It loads for a moment and then I get this error screen:

——————–
Assert Failed:

(region != nullptr)

SpineDataBinaryLoader::ReadAttachment in spinedata_binary_loader.cpp line 402

couldn’t find region

ESC to skip
——————–

After this, the game crashes. I tried again without the custom class and it worked fine. So, the error only occurs when the custom class is in the party

Any ideas or suggestions at what may be causing this?

Usually a crash when entering or exited a dungeon is the result of a problem with one of your skills. Either the naming of the skill or something like a comma or quotation is missing from the code. Check your .info and .art files for any grammatical errors.

Thanks, but as far as I can tell, everything looks correct. Obviously it isn't, but I can't seem to find it. I've looked over every file numerous times. Does anyone know how to figure out exactly what the error is pointing toward?

Unfortunately as far as I know - just by eye. Also check your localization file to make sure there are no errors there. One little grammatical error can cause a crash.

I remember my first mod - I spent 2 days just to find I was missing a period.

Another thing to make sure you check is the naming of your files: Make sure that all anim, fx, and art files are named correctly - and that ALL atlas files have been opened and the correct class name has been put in there as well and saved (all atlas files in fx and anim folders).

Remember:

-Monster files cannot work with hero files (explosions!)
-Never change the string names/code of a file (apocalypse!)

spinedata_binary_loader.cpp
this error comes from mismatch of .atlas and .skel in sprite data
mostly appears when .atlas was edited with ctrl+h, while you have to replace only one string contains .png
it may help to use spine viewer to track this problem

toss all .atlas .skel and .png files in same folder of skin that you suspect. and check each .skel for white squares
