I followed this tutorial on youtube: Unity3D. Top-down 8 directions movement - YouTube[^]. It took me a while but I've almost converted from movement by arrows to mouse touch . but now I have this problem, there's flickering that occurs when the character stops moving. I looked at the link he sent me but it doesn't work. Please look at this video to show you what I am talking about: My unity problem - YouTube[^]. Does anyone knows how to stop the flickering that occurs when the character stops moving? This is my code:

   

private Animator anim;
    public float speed = 15f;
    private Vector3 target;
    private bool touched;
    
    
    void Start () {
        target = transform.position;
        anim = GetComponent<Animator> ();
    }
    
    void Update () {
        touched = true;
        if (Input.GetMouseButtonDown (0)) {
            Vector3 mousePosition = Input.mousePosition;
            mousePosition.z = 10; // distance from the camera
            target = Camera.main.ScreenToWorldPoint(mousePosition);
            target.z = transform.position.z;
        }


            
            var movementDirection = (target - transform.position).normalized;
            
            if (movementDirection.x != 0 || movementDirection.y != 0) {
                anim.SetBool("walking" , true);
                anim.SetFloat("SpeedX" , movementDirection.x);
                anim.SetFloat("SpeedY" , movementDirection.y);
                
                Vector2 movement = new Vector2(
                    speed * movementDirection.x ,
                    speed * movementDirection.y);
                movement *= Time.deltaTime;
                transform.Translate(movement);
                
                if (movementDirection.x < 0) {
                    anim.SetFloat("LastMoveX" , -1f);
                }
                else if (movementDirection.x > 0) {
                    anim.SetFloat("LastMoveX" , 1f);
                }
                else {
                    anim.SetFloat("LastMoveX" , 0f);
                }
                if (movementDirection.y > 0) {
                    anim.SetFloat("LastMoveY" , 1f);
                }
                else if (movementDirection.y < 0) {
                    anim.SetFloat("LastMoveY" , -1f);
                }
                else {
                    anim.SetFloat("LastMoveY" , 0f);
                }
            } else {
            touched = false;
            anim.SetBool("walking" , false);
        }
    }

What I have tried:

I have tried the following: 
https://josejimenez.info/blog/unity3d-top-down-8-direction-movement.html

I've Tried checking out what happens if I add something like

 

if (movementDirection.x != 0 || movementDirection.y != 0) {
anim.SetFloat("SpeedX", movementDirection.x);
anim.SetFloat("SpeedY", movementDirection.y);
}

and

if (movementDirection.x != 0 || movementDirection.y != 0) {
float rot_z = Mathf.Atan2 (movementDirection.y, movementDirection.x) * Mathf.Rad2Deg;
transform.rotation = Quaternion.Euler (0f, 0f, rot_z);
}

as well as 
transform.rotation = Quaternion.Euler (0f, 0f, rot_z - 90)
