Keep getting player not defined, but it should be defined as x, y

it might be because you set y = player and then did if statements changing y but that does not change the value of player. This may or may not be why just throwing ideas out there.

Ive edited the question so it can be read better

x, y = player

thats how it was done in the video

I had the same problem. Change out all start variables for player variables.
