How do i rotate player (aeroplane) using A/D keys while moving Left/Right at the same time

public class CharacterControls : MonoBehaviour
{
public float moveSpeed;
public GameObject Player;

    //tranfrom, neutral
    public float Neutral = 0f;
    public float Transform;
    public float zRotation;
    public float minClamp = -20f;
    public float maxClamp = 20f;

    // Start is called before the first frame update
    void Start()
    {
        moveSpeed = 50f;
        
    }

    // Update is called once per frame
    void Update()
    {
        transform.Translate(moveSpeed * Input.GetAxis("Horizontal") * Time.deltaTime, 0f, 0f);

        zRotation = Mathf.Clamp(zRotation - Input.GetAxis("Horizontal") * moveSpeed, minClamp, maxClamp);
        transform.eulerAngles = new Vector3(0.0f, zRotation);

    }
}

The problem in your script is that you wrote Input.GetAxis horizontal.
Horizontal axis is A D and Left and Right arrows, so if the movement must be only with the arrows, you must write

void Update()
{
  transform.Translate(moveSpeed * Input.GetKey(KeyCode.LeftArrow) * Time.deltaTime, 0f, 0f);
     
  zRotation = Mathf.Clamp(zRotation - Input.GetKey(KeyCode.RightArrow) * moveSpeed, minClamp, maxClamp);
  transform.eulerAngles = new Vector3(0.0f, zRotation);

}

Then, to rotate, use the transform.Rotate function. It’s the same code that moves the aeroplane, but it will rotate it, but now you must change the Left and Right Arrows to A and D
I hope this helps you :slight_smile:
