the class name is 'qc.engine.playerScript' but not 'playerScript'.
I know how occurs but i don't know how to fix it.
in publish the prefab throws an error.
i had to place the prefab to the game heirarchy and unmake it prefab. The error dissapear, but it throws it again with other sprite with a script attached.
Can you send the project to me?
It's strange case, normally the preview works then publish should works with no different. Can you send your project with error reappearable to my colleague's mail weism@qcplay.com, so we can help you to check this issue.
I was going to publish the soolution you gave me but i was too slow haha.
exactly i was missing qc.engine. before the script name.
