Help with mobile touch dual stick controls. Rotate or Snap character to the right stick. (Top Down)

Hi all,

This might be a noob-of-the-year worthy question, so sorry, but I have wasted so much time already on this... Basically I found a script which I managed to implement into my game. It allows me to control my character by using 1 stick mobile input.

Sadly it makes the game rubbish as the game was originally dual stick (mouse and keys). I would really appreciate some help separating the bit of code I have into two sticks...

I have fiddled with it and searched all over and have only broken what works and have not achieved what I want so I am desperate now (I broke it so that the player turns right when I press up- but i think i will find a way to fix that myself).

Thank you for any input everyone (clearly I am not a programmer, but I am learning, just very slowly- always used PlayMaker in the past).

I would like the character to snap to face a direction (or rotate) according to the right stick, much like in geometry wars, and continue to move using the left stick.

Bit of Code I think I need to Split : (starts on line 106 in full script)

 Vector3 turnDir = new Vector3(CrossPlatformInputManager.GetAxisRaw("Horizontal"), 0f, CrossPlatformInputManager.GetAxisRaw("Vertical"));
          if(turnDir != Vector3.zero){
             Vector3 playerToMouse = (transform.position + turnDir) - transform.position;
             playerToMouse.y = 0;
             Quaternion newRotation = Quaternion.LookRotation(playerToMouse);
             playerRigidBody.MoveRotation(NewRotation); 
         }

Entire Script:

 using UnityEngine;
 using System.Collections;
 using UnityStandardAssets.CrossPlatformInput;
 using UnityEngine.UI;
 
 public class GrunkBehaviorScript : MonoBehaviour {
 
     public float speed = 2.0f;
     public GameObject gameOverPanel;
     PlayerHealth playerHealth;
     public int score;
     public Text scoreText;
 
     Vector3 movement;
     Rigidbody playerRigidBody;
     bool isMoving = false;
     Animator anim;
     int floorMask;
     float camRayLength = 100.0f;
     public bool isEnabled = true;
     public bool gameOver = false;
 
     // Use this for initialization
     void Start () {
         gameOverPanel.SetActive (false);
         GameObject player = GameObject.FindGameObjectWithTag ("Player");
         playerHealth = player.GetComponent<PlayerHealth> ();
         score = 0;
         scoreText.text = "Score: 0";
     
     }
     
     // Update is called once per frame
     void Update () {
         if (playerHealth.currentHealth <= 0) {
             isEnabled = false;
         if (!gameOver) {
             Invoke ("DisplayGameOver", 1.0f);
             }
         }
 
         scoreText.text = "Score: " + score.ToString ();
 
     }
 
     void Awake() {
         playerRigidBody = GetComponent<Rigidbody> ();
         anim = GetComponent<Animator> ();
         floorMask = LayerMask.GetMask ("Floor");
     }
 
     void FixedUpdate (){
         if (isEnabled == false)
             return;
         // get button pressed by player
         float h = CrossPlatformInputManager.GetAxisRaw ("Horizontal");
         float v = CrossPlatformInputManager.GetAxisRaw ("Vertical");
 
         Move (h, v);
 
         if (h !=0 || v != 0) {
             isMoving = true;
         } else {
             isMoving = false;
         }
         Animating ();
         Turning ();
     }
 
 
     void Move( float h, float v){
         movement.Set (v, 0f, -h);
 
         movement = movement.normalized * Time.fixedDeltaTime * speed;
 
         playerRigidBody.MovePosition (transform.position + movement);
 
     }
 
 
     void Animating(){
         // if char is moving, then play walk anim, if not play idle anim
         if (isMoving == true) {
             //if true play animation
             anim.SetFloat ("speed", 1);
         } else {
             anim.SetFloat ("speed", 0);
         }
     }
 
     void Turning(){
         //Find Mouse Position and check if in range
         //if in range, rotate character towards mouse
 
         #if !MOBILE_INPUT
         Ray camRay = Camera.main.ScreenPointToRay (Input.mousePosition);
         RaycastHit floorHit;
         if (Physics.Raycast (camRay, out floorHit, camRayLength, floorMask)) {
             Vector3 playerToMouse = floorHit.point - transform.position;
             playerToMouse.y = 0.0f;
             Quaternion newRotation = Quaternion.LookRotation(playerToMouse);
             playerRigidBody.MoveRotation(newRotation);
 
         }
         #else
         Vector3 turnDir = new Vector3(CrossPlatformInputManager.GetAxisRaw("Horizontal"), 0f, CrossPlatformInputManager.GetAxisRaw("Vertical"));
          if(turnDir != Vector3.zero){
             Vector3 playerToMouse = (transform.poition + turnDir) - transform.position;
             playerToMouse.y = 0;
             Quaternion newRotation = Quaternion.LookRotation(playerToMouse);
             playerRigidBody.MoveRotation(NewRotation); 
         }
         #endif
     }
 
 
     public void DisableMovement(){
         isEnabled = false;
     }
 
     public void RestartGame(){
         Application.LoadLevel ("SceneWithSpidersAndStuff");
     }
 
     void DisplayGameOver(){
             gameOver = true;
         gameOverPanel.SetActive (true);
     }
 }

I think this bit of code works perfectly with the mouse to do what I want, but im not sure:

          Ray camRay = Camera.main.ScreenPointToRay (Input.mousePosition);
          RaycastHit floorHit;
          if (Physics.Raycast (camRay, out floorHit, camRayLength, floorMask)) {
              Vector3 playerToMouse = floorHit.point - transform.position;
              playerToMouse.y = 0.0f;
              Quaternion newRotation = Quaternion.LookRotation(playerToMouse);
              playerRigidBody.MoveRotation(newRotation);

Thanks again to anyone reading.
