When I enter this code my player character doesn’t move. What’s the fix?

if you want to move something,
you need to SET some value to your GameObject’s
“transform.position” .

assigning playerMovement value in your code, doesn’t mean anything. because you are not using that value.
nothing is using that value, except itself
