The key function returns an integer value from a key input. Which then i input into the d function to move the snake around using the snakex and snakey variables. If you look at the d function it has 3 parameters. Everything seems like it should be a okay, but im getting these errors.
Line 64 is what needs to work.

Im having problems with the d function. The key() function is supposed to input in the the d() function along with the snakex, and snake y variables through reference. Line 64 should work in theory, but it doesn't.
