, and it still brings this up as a problem, can anyone help, its been bugging me for days? i don’t know whats caused it and i goes on and off.
also this is my first time using the unity forum so tell me if i’ve done anything wrong.

  • Do you have any compile errors?
  • Do all of the class names match the filenames for all of your scripts?
