Moving Forward While Rotating

I am trying to make an object (that rotates left and right when the a/d keys are pressed) move forward according to the direction it is facing, currently, I have only been able to move it straight along the x axis.
How would I be able to make it go forward to the place that it is facing?163563-screenshot-29.png

Im guessing you will want to add the force relative to the transform’s forward vector.
Use rb.AddForce(transform.forward * forwardSpeed * Time.fixedDeltaTime) and the force should be added in the forward direction.
