How can I rotate my player with a Joystick?

Hello, Unity community!

I got a problem with my script/Gameobject, which does not want to rotate in my Joysticks direction. The Script which I have written now just rotates the player to the cursor and not to the (virtual) Joysticks´ direction. I appreciate it, if somebody could help me, because I am pretty new to coding. Script (with the controls for android):

using System.Collections; using System.Collections.Generic; using UnityEngine; using UnityStandardAssets.CrossPlatformInput;

public class PlayerController : MonoBehaviour { public float moveSpeed; private Rigidbody myRigidbody; private Vector3 moveInput; private Vector3 moveVelocity; private Camera mainCamera;

 void Start() { myRigidbody = GetComponent<Rigidbody>();
     mainCamera = FindObjectOfType<Camera>(); }
 void Update() {
     moveInput = new Vector3(CrossPlatformInputManager.GetAxisRaw("Horizontal"), 0f, CrossPlatformInputManager.GetAxisRaw("Vertical"));
     moveVelocity = moveInput * moveSpeed;
     Ray cameraRay = mainCamera.ScreenPointToRay(CrossPlatformInputManager.mousePosition);
     Plane groundPlane = new Plane(Vector3.up, Vector3.zero);
     float rayLength; if (groundPlane.Raycast(cameraRay, out rayLength))
     {
         Vector3 pointToLook = cameraRay.GetPoint(rayLength);
         Debug.DrawLine(cameraRay.origin, pointToLook, Color.red);
         transform.LookAt(new Vector3(pointToLook.x, transform.position.y, pointToLook.z));
     }
 }
 private void FixedUpdate() {
     myRigidbody.velocity = moveVelocity;
 }

}
