Unity 5 2D Flip Player - position

Question

I made player script with touch location and Flip code to flip player wich direction is run i made like this but just flip from 0. If is on x = -5 and i touch to go in x = 2 player dont flip but when is on x = 0 is flip. Can someone tell me how to do this and i like to make with flor but my player move only on one flor in yAxis direction it save but when i remove yAxis it move all around i like to move like this gameGame
if (gameObject.transform.position.x > 0 && faceRight)
{
Flip();
}
else if (gameObject.transform.position.x < 0 && !faceRight)
{
Flip();
}

{

//save the y axis value of gameobject
yAxis = gameObject.transform.position.y;
}
// Update is called once per frame
void Update()
{
//check if the screen is touched / clicked
if ((Input.touchCount > 0 && Input.GetTouch(0).phase == TouchPhase.Began) || (Input.GetMouseButtonDown(0)))
{
//declare a variable of RaycastHit struct
RaycastHit hit;
//Create a Ray on the tapped / clicked position
Ray ray;
//for unity editor
#if UNITY_EDITOR
ray = Camera.main.ScreenPointToRay(Input.mousePosition);
//for touch device
#elif (UNITY_ANDROID || UNITY_IPHONE || UNITY_WP8)
ray = Camera.main.ScreenPointToRay(Input.GetTouch(0).position);
#endif
//Check if the ray hits any collider
if (Physics.Raycast(ray, out hit))
{
//set a flag to indicate to move the gameobject
flag = true;
//save the click / tap position
endPoint = hit.point;
//as we do not want to change the y axis value based on touch position, reset it to original y axis value
endPoint.y = yAxis;
Debug.Log(endPoint);
}
}
//check if the flag for movement is true and the current gameobject position is not same as the clicked / tapped position
if (flag && !Mathf.Approximately(gameObject.transform.position.magnitude, endPoint.magnitude))
{ //&& !(V3Equal(transform.position, endPoint))){
//move the gameobject to the desired position
gameObject.transform.position = Vector3.Lerp(gameObject.transform.position, endPoint, 1 / (duration * (Vector3.Distance(gameObject.transform.position, endPoint))));
Run = true;
anim.SetBool("Run", Run);
if (gameObject.transform.position.x > 0 && !faceRight)
{
Flip();
}
else if (gameObject.transform.position.x < 0 && faceRight)
{
Flip();
}
}
//set the movement indicator flag to false if the endPoint and current gameobject position are equal
else if (flag && Mathf.Approximately(gameObject.transform.position.magnitude, endPoint.magnitude))
{
flag = false;
Run = false;
anim.SetBool("Run", Run);
Debug.Log("I am here");
}
}
void Flip()
{
faceRight = !faceRight;
Vector3 theScale = transform.localScale;
theScale.x *= -1;
transform.localScale = theScale;
}
}

Answer 1

Well my anwer will be diffrent from your code but if you want to flip character when you running left (i am assuming the default as right), you can simply check
if character's velocity > 0 then scale 1 and if character's velocity < 0 then scale -1
That will face the character to the rotation you go and this will be easy than the original code, but if you want to achieve something else please let me know so i can correct my answer on your needs :)

Answer 2

Flipping the character seems to be a thing that Animator should handle. I saw that you're already using Animator, so you should make something like:
anim.SetInteger("direction", 1)
or even:
anim.SetFloat("position", transform.position.x)
and configure the animator to act accordingly, creating the animation states with the character facing left and right (with the gameObject's transform scale.x 1 and -1 or rotation.y 0 and 180) and the transitions to respond to the events you decided to watch.
