Script only makes character run forward

Question

Hi,

Trying to use the Locomotion starter pack script from the Asset store to try and make my own fully functioning controller. I have one problem though, the script seems to always be making my character move forwards i.e. going from 0 to 6 speed float (Mecanim) when I press S as well as W. I can't really figure out what part I am missing.

 public class JoystickToEvents : MonoBehaviour 
 {
     public static void Do(Transform root, Transform camera, ref float speed, ref float direction)
     {
         Vector3 rootDirection = root.forward;
         float horizontal = Input.GetAxis("Horizontal");
         float vertical = Input.GetAxis("Vertical");
                 
         Vector3 stickDirection = new Vector3(horizontal, 0, vertical);
         
 
         // Get camera rotation.    
 
         Vector3 CameraDirection = camera.forward;
         CameraDirection.y = 0.0f; // kill Y
         Quaternion referentialShift = Quaternion.FromToRotation(Vector3.forward, CameraDirection);
 
         // Convert joystick input in Worldspace coordinates
         Vector3 moveDirection = referentialShift * stickDirection;
                 
         Vector2 speedVec =  new Vector2(horizontal, vertical);
         speed = Mathf.Clamp(speedVec.magnitude, -1, 1);      
 
         if (speed > 0.01f) // dead zone
         {
             Vector3 axis = Vector3.Cross(rootDirection, moveDirection);
             direction = Vector3.Angle(rootDirection, moveDirection) / 180.0f * (axis.y < 0 ? -1 : 1);
         }
         else
         {
             direction = 0.0f;
         }
     }
     
 }

Is there a line of code im missing in order to get my WalkBack state to start working correctly? Thanks!

speed in there should be between -1 and 1 0 meaning standing the animations will control your speed that is set in the animation setup. coding for mecanim is a bit different than a character controller instead of coding speed being how fast to move you will code 1 being moving forward at full speed and -1 moving backward at full speed.

here is a simple movement script to help understand it

 using UnityEngine;
 using System.Collections;
 
 public class PlayerMovement : MonoBehaviour {
     private Animator _droidAnimator;
     private float _horMove;
     private float _vertMove;
 
 
     public float animSpeed = 1.5f;
     
     
     
     // Use this for initialization
     void Start () {
         _droidAnimator = GetComponent<Animator>();
         
     }
     
 
     void LateUpdate () {
         _horMove = Input.GetAxis("Horizontal");
         _vertMove = Input.GetAxis("Vertical");
         _droidAnimator.SetFloat("Direction", _horMove);
         _droidAnimator.SetFloat("Speed", _vertMove);
         _droidAnimator.speed = animSpeed;
         
             
         
 //        if(_controller.isGrounded){
             if(Input.GetButtonDown("Jump")){
                 _droidAnimator.SetBool("Jump", true);
                 
                         
             }else{
             _droidAnimator.SetBool("Jump", false);
         }
         
 
     
     }
 }

Tried your script and quickly changed mine over to your more understandable one. this was a very nice starting point and fixed my problems with walking backwards and I got the jumping referenced in the script to work easily.

Thankyou $$anonymous$$r. Bodec! :)
