My CharacterController does not walk and face in the same direction

Questions & Answers

When I go left my CharacterController turns left which is good but he walks to the right. Going right works fine and while I know why hes walking backwards I cannot figure out how to fix it. This is a 2D game movement is on the X axis.

    var speed 				: float 					= 4.0;
  //var speedo 				: float 					= -4.0;
    var gravity 			: float 					= 20.0;
    private var velocity 	: Vector3 					= Vector3.zero;
    var controller 			: CharacterController;
    
    function Update () 
    {
    	if (controller.isGrounded)
    	{
    		velocity = GetHorizontalMovement();
    		velocity *= speed;
    	}
    	velocity.y -= gravity * Time.deltaTime;
    	controller.Move (velocity * Time.deltaTime);
    
    	if(Input.GetAxisRaw("Horizontal") > 0)
    		transform.rotation = Quaternion.Euler(0, 0, 0);
    	else if(Input.GetAxisRaw("Horizontal") < 0)
    		transform.rotation = Quaternion.Euler(0, 180, 0);
    }
    
    function GetHorizontalMovement()
    {
         var direction : Vector3 = Vector3 (Input.GetAxisRaw("Horizontal"), 0, 0);
         return transform.TransformDirection (direction);
    }

The problem is that your horizontal movement changes between + / - when pressing left / right. At the same time, the character also changes rotation depending on what key you press. (Pressing right; character faces right and moves forward, pressing left; character faces left and moves backwards). So rather than changing the characters velocity between positive or negative, just make it equal to speed when there is input:

if(Input.GetAxis("Horizontal") > 0f) {
    velocity.z = speed;
}

EXAMPLE SCRIPT:

   var speed           : float             = 4.0;
  //var speedo           : float            = -4.0;
    var gravity          : float            = 20.0;
    private var velocity    : Vector3               = Vector3.zero;
    var controller         : CharacterController;
 
    function Update () 
    {
        if (controller.isGrounded)
        {
           if(Input.GetAxisRaw("Horizontal") > 0) {
               velocity.x = speed;
           }
        }
        velocity.y -= gravity * Time.deltaTime;
        controller.Move (velocity * Time.deltaTime);
 
        if(Input.GetAxisRaw("Horizontal") > 0)
           transform.rotation = Quaternion.Euler(0, 0, 0);
        else if(Input.GetAxisRaw("Horizontal") < 0)
           transform.rotation = Quaternion.Euler(0, 180, 0);
    }

Make the Input.GetAxisRaw("Horizontal") a negative value like -(Input.GetAxisRaw("Horizontal")). For the GetHorizontalMovement() function.

Ok figured it out although I’m not 100% sure how I did it.

var speed 				: float 					= 4.0;
var gravity 			: float 					= 20.0;
private var velocity 	: Vector3 					= Vector3.zero;
var controller 			: CharacterController;

function Update () 
{
	if (controller.isGrounded && Input.GetAxisRaw("Horizontal") > 0)
	{
		transform.rotation = Quaternion.Euler(0, 0, 0);
		velocity = GetHorizontalMovement();
		velocity *= speed;
	}

	else if(controller.isGrounded && Input.GetAxisRaw("Horizontal") < 0)
	{
		transform.rotation = Quaternion.Euler(0, 180, 0);
       	velocity = GetHorizontalMovement();
		velocity *= speed;
	}
	
	else if(controller.isGrounded)
	{
		velocity = GetHorizontalMovementZero();
	
	}

velocity.y -= gravity * Time.deltaTime;
controller.Move (velocity * Time.deltaTime);
	
}

function GetHorizontalMovement()
{
var direction : Vector3 = Vector3 (1, 0, 0);
return transform.TransformDirection (direction);
}

function GetHorizontalMovementZero()
{
var direction : Vector3 = Vector3 (0, 0, 0);
return transform.TransformDirection (direction);
}
