The camera part I’ve managed to do as I wanted. My actual problem is that I whenever I press the S key (for the rabbit to go backwards), it always go to a specific direction (or axis), and not the direction based to the actor rotation.
It should look like the old Resident Evil games (or World of Warcraft), like whenever I press the “reverse” key (S), the actor will start going backwards, but keeping the same rotation (like reversing a car).
