up arrow goes left, down arrow goes right

I don't know what did I do, for the First Person Control, now up arrow goes left, down arrow goes right. It should be up arrow goes forward, down arrow goes backward. How can I change them back? Thanks

Make sure your character's graphics haven't been rotated. It may still be doing the correct behaviour and it's just that the visual is off.

click on edit then click on project settings then input. from here you can adjust your buttons :)
