To go straight, you have to press the front arrow key or "w", to go backwards, the back one or "s", to turn left, the left arrow, and to turn right, the right one. To move to the left, "a" and to move to the right, "d". This is my first 3d project, so don't hesitate to like it and bookmark it. Enjoy !
