VirtualJoystick issues with unity5 - unity3d

Question

I have two problems with implementing two Virtual Joysticks in Unity 5: one for player movement (grey color) and the second for camera (orange color) please see the following screenshot:
My problems:
For the Virtual Joystick responsible for player movement, the player object does not rotate in the same direction the Joystick is pressed , it's moving in all directions but not facing the same direction that the Joystick is pressed.
The camera can see through the terrain/ground. How do I prevent that?
The script I'm 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 to move the player:
using UnityEngine; using System.Collections;
public class Motor : MonoBehaviour {
public float moveSpeed = 5.0f;
public float drag = 0.5f;
public float terminalRotationSpeed = 25.0f;
private Rigidbody controller;
private Transform camtransform;
public VirtualJoystick movejoystick;
private void Start()
{
controller =GetComponent<Rigidbody>();
controller.maxAngularVelocity = terminalRotationSpeed;
controller.drag = drag;
camtransform = Camera.main.transform;
}
private void Update ()
{
Vector3 dir = Vector3.zero;
dir.x = Input.GetAxis ("Horizontal");
dir.z = Input.GetAxis ("Vertical");
if (dir.magnitude > 1)
dir.Normalize ();
if (movejoystick.InputDirection != Vector3.zero) {
dir = movejoystick.InputDirection;
}
Vector3 rotatedDir = camtransform.TransformDirection (dir);
rotatedDir = new Vector3 (rotatedDir.x, 0, rotatedDir.z);
rotatedDir = rotatedDir.normalized * dir.magnitude;
controller.AddForce (dir * moveSpeed);
Quaternion eulerRot = Quaternion.Euler(0.0f, 0.0f, rotatedDir.x);
transform.rotation = Quaternion.Slerp(transform.rotation, eulerRot, Time.deltaTime * 10);
}
}
The script I'm using for the 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);
}
}

Answer 1

For question 1:
The code below first turns according to joystick-x direction and then move forward/backward according to joystick-y. In Motor.Update:
private void Update ()
{
Vector3 dir = Vector3.zero;
dir.x = Input.GetAxis ("Horizontal");
dir.z = Input.GetAxis ("Vertical");
if (dir.magnitude > 1)
dir.Normalize ();
if (movejoystick.InputDirection != Vector3.zero) {
dir = movejoystick.InputDirection;
}
Vector3 rotatedDir = transform.TransformDirection (dir); // world direction of joystick direction
Vector3 newDir = Vector3.RotateTowards(transform.forward, rotatedDir, Time.deltaTime * 10f, 0.0F); // turn towards joystick direction
transform.rotation = Quaternion.LookRotation(newDir); // set the new direction
controller.AddForce (transform.forward * moveSpeed * dir.z); // scale force by joystick up/down
}
