Help with touch input.

Hi, I'm kinda new to unity and I am playing around with touch controls. I am making a sort of space shooting game where the player controls the character with touch input. The touch is for moving the character around. my problems is that, when I tap to a space in the screen, the character jumps onto that area that I have tapped.

here is a sample of the game : https://developer.cloud.unity3d.com/share/Wk9HwJPTMG/

Also I have made a fire button, where the player should press that in order to fire, the problem is my character jumps to where the fire button is.

Is there a way to restrict the touch to not jump around whenever the player touch other spaces of the screen?

• See attached Codes and SS below.

Thank you!

Here is my code :

 if (getInput())
         {
             Vector3 rawPosition = cam.ScreenToWorldPoint(Input.mousePosition);
             float x = Mathf.Clamp(rawPosition.x, -2.81f, 2.81f);
             float y = Mathf.Clamp(rawPosition.y, -4.5f, Camera.main.orthographicSize);
             Vector3 targetPosition = new Vector3(x, y, 0);
             GetComponent<Rigidbody2D>().MovePosition(targetPosition*Time.deltaTime*40f);

         //Instantiate(bullet, transform.position, Quaternion.identity);
     }
     else
     {
         
         Vector2 pos = transform.position;

         pos.x += Input.GetAxis("Horizontal") * speed * Time.deltaTime;
         pos.y += Input.GetAxis("Vertical") * speed * Time.deltaTime;

         #region Position Check
         if (pos.y > Camera.main.orthographicSize)
         {
             pos.y = Camera.main.orthographicSize;
         }
         else if (pos.y <= -4.5f)
         {
             pos.y = -4.5f;
         }
         
         if(pos.x >= 2.81f)
         {
             pos.x = 2.81f;
         }
         else if( pos.x <= -2.81f)
         {
             pos.x = -2.81f;
         }
         #endregion

         transform.position = pos;
     }
 bool getInput()
     {
         bool fire = Input.GetButton("Fire1");
         bool touch = Input.touchCount > 0;
         return fire || touch;
     }

and here is how my game looks like
