When I decrease the rotation y of my character, the character moves to the left, when I increase it, it moves to the right. In the tutorials I watched, the character turns directly left and right without changing its position.
(But position degree don’t change when I change the rotetion, only image.)
And sorry for my bad english 
I’m not really sure how exactly is your position getting affected by the rotation. Ideally that shouldn’t happen. Are you increasing and decreasing the rotation through code or through the inspector??
