The referenced script on this behavior is missing!

I’ve just began using unity, and I am doing the Space Shooter Project, I’m on
Video 6 (moving the player), and I’m stuck. I’m programming movement for the Spaceship, and one of the scripts is missing. Here is a link of my screen. Any help is appreciated. I’ve tried copying code directly fromt he tutorial video’s description, but it doesn’t work.

I think player only needs one player controller script, and you have two, I guess the missing one, done_player controller is the one done by the instructor. Have you tried just to remove the missing script component or replace the player controller by the done player controller?

Thank you! It worked.
