issue with Virtual Joystick

Hello all

Kindly I facing 2 issues with my Virtual Joystick developed over unity5 , kindly I need your support to solve the issue where I have 2 Virtual Joysticks one for player moving (Gris color) and the second for camera (orange color) please see the following screenshoot:

My issues as the following: 1- For the Virtual Joystick responsible about the player moving , the player object not rotate in the same direction of the Joystick pressed , its moving in all direction but not facing the same direction of the Joystick pressed . 2- The camera can see through the Terrain “ground ” how to prevent that.

The script im using from Virtual Joystick :
using UnityEngine; using System.Collections; using UnityEngine.UI; using UnityEngine.EventSystems;

public class VirtualJoystick : MonoBehaviour,IDragHandler,IPointerUpHandler,IPointerDownHandler {

 private Image bgImg;
 private Image joystickImg;
 public Vector3 InputDirection{ set; get;}
 // Use this for initialization
 void Start () {
     bgImg = GetComponent<Image> ();
     joystickImg = transform.GetChild (0).GetComponent<Image> ();
     InputDirection = Vector3.zero;

 }

 // Update is called once per frame
 //void Update () {

 //}
 public virtual void OnDrag(PointerEventData ped)
 {
     Vector2 pos = Vector2.zero;
     if (RectTransformUtility.ScreenPointToLocalPointInRectangle
         (bgImg.rectTransform,
             ped.position,
             ped.pressEventCamera,
             out pos)) {
         pos.x=(pos.x/bgImg.rectTransform.sizeDelta.x);
         pos.y=(pos.y/bgImg.rectTransform.sizeDelta.y);
         float x=(bgImg.rectTransform.pivot.x==1) ? pos.x*2+1 : pos.x*2-1;
         float y=(bgImg.rectTransform.pivot.y==1) ? pos.y*2+1 : pos.y*2-1;
         InputDirection=new Vector3(x,0,y);
         InputDirection=(InputDirection.magnitude>1) ? InputDirection.normalized : InputDirection;

         joystickImg.rectTransform.anchoredPosition=
             new Vector3(InputDirection.x*(bgImg.rectTransform.sizeDelta.x/3),InputDirection.z*(bgImg.rectTransform.sizeDelta.y/3));
         Debug.Log(InputDirection);
     }

 }
 public virtual void OnPointerDown(PointerEventData ped)
 {
     OnDrag (ped);

 }
 public virtual void OnPointerUp(PointerEventData ped)
 {


     //Here is the problem it just goes to zero so fast so my character also moves so fast...how can i make it so motth
     InputDirection =Vector3.zero;
     joystickImg.rectTransform.anchoredPosition =Vector3.zero;
 }

}

The script im using for camera :

 using UnityEngine;
 using System.Collections;
 
 public class FreeCamera : MonoBehaviour {
     public Transform lookAt;
     public VirtualJoystick camerajs;
     private float distance = 200.0f;
     private float currentx = 0.0f;
     private float currenty = 0.0f;
     private float sensitivityx = 1.0f;
     private float sensitivityy = 1.0f;
     private void Update()
     {
         currentx += camerajs.InputDirection.x * sensitivityx;
         currenty += camerajs.InputDirection.z * sensitivityy;
     }
     private void LateUpdate()
     {
         Vector3 dir = new Vector3(0, 0, -distance);
         Quaternion rotation = Quaternion.Euler(currenty, currentx, 0);
         transform.position = lookAt.position + rotation * dir;
         transform.LookAt(lookAt);
     }
 }
