Okay, so I, at this time, am trying to create a game, and I have completed the main menu (mostly). When I decided to test the main menu, the Options and quit buttons worked just fine, but when I clicked Start, I got this error message. I watched this video (https://www.youtube.com/watch?v=ulUO4EN8BG8) by CodeViper. I did everything that he said in the tutorial, except that I chose First Person instead of Third Person, because I am trying to make a shooter game. I am almost 99% sure that it isn’t the fact that I chose 1st person, because I highly doubt that it is specific to 3rd person only. Can anyone in the comments explain this?
