Beginner project: Survival shooter - compiler error

Hi Unity Community!

I am totally new to Unity and game development and therefore I am trying to follow the video tutorials for the beginner project: Survival shooter.

As I was about to finish lesson 2: Player Character, I followed along on the scripting, saved it with ctrl+s and went back to Unity to try to see the results and my player moving.

I get the following errors in my console, when I try to run the game:

I hope you are able to help me out. :slight_smile:
Thanks in advance.

could it be because that MonoDev. is not set to be default program?
could it be because of some Unity settings that I didn’t take care of before I started?
