2d Movement Jumps to the Left

Hello,

I'm beginning to use Unity and I've been following the excellent tutorials on http://unity3d.com/learn/tutorials/modules/beginner/2d.

I'm on the last beginners video "2d Character controllers" https://www.youtube.com/watch?v=Xnyb2f6Qqzg.

My character now have basic left and right movement that can flip. Only problem is when I move left his sprites jumps halfway across the cameras screen. I'm concerned that it may be because I'm using many sprites to build my character instead of the single sprite character that makes up the character in the tutorial. I may be wrong but I can't seem to find a solution.

I've gone over the code a few times and still cannot see my problem. In C# I have the following.

using UnityEngine; using System.Collections;

public class RobotController : MonoBehaviour {

     public float maxspeed = 10f;
     bool facingRight = true;
     
     void Start () 
     {}
     
     
     void FixedUpdate () 
     {
         float move = Input.GetAxis ("Horizontal");
         
         rigidbody2D.velocity = new Vector2(move * maxspeed, rigidbody2D.velocity.y);
         
         if(move > 0 &&!facingRight)
             Flip ();
         else if(move < 0 && facingRight)
             Flip ();    
     }
     
     void Flip()
     {
         facingRight = !facingRight;
         Vector3 theScale = transform.localScale;
         theScale.x *= -1;
         transform.localScale = theScale;
     }
 }

Any help is much appreciated.
