When I type in any code to let my player flip 180 when a key is pressed everything in my gameview just disappears.

I just don’t know what the problem is I’ve tried searching for the answer. everytime I try to write any script that allows my player to be flipped when walking in the left direction everything in my game view disappears but everything in my scene view is fine. I use Unity could it be because of all the updates unity has.

Sounds like you’re flipping the Camera - that would explain everything.
