Unity 3 GD HotShot-Tutorial Problem with an C#-Array

Hey Folks, i've got a Problem. I bought a book Unity 3 Game Development HotShot, which is pretty awesome. But i have a problem. There is a task, where i have to make a little 2D project. So one has to make a SpriteManager class, this here:

 using UnityEngine;

using System.Collections;

public class CharacterController_2D : MonoBehaviour {

 public float f_speed = 5.0f;
 public Manager[] loopSprites;
 public int in_direction;

 // Use this for initialization
 void Start () 
 {
 
     in_direction = 1;
     
     for(int i = 0; i<loopSprites.Length; i++)
     {
         loopSprites[1].init();
     }
     
     Camera.main.transform.position = new Vector3(transform.position.x, transform.position.y, Camera.main.transform.position.z);
 
 
 
 }
 
 // Update is called once per frame
 void Update () 
 {
     
     if(Input.GetButton("Horizontal"))
     {
         in_direction = Input.GetAxis("Horizontal") < 0 ? -1:1;
         rigidbody.velocity = new Vector3((in_direction*f_speed), rigidbody.velocity.y,0);
         
         // Reset Stay animation frame back to the first frame
         
         loopSprites[0].resetFrame();
         
         //Update Walking animation
         
         loopSprites[1].updateAnimation(in_direction,renderer.material);
         
     }
 
 }
 
 
 public void LateUpdate()
 {
     
     //Update Main Camera
     
     Camera.main.transform.position = new Vector3(transform.position.x, transform.position.y, Camera.main.transform.position.z);
 }
 

 
 public class Manager
 {
     public Texture2D spriteTextur;
     public int in_framePerSec;
     public int in_gridX, in_gridY;
     
     private float f_timePercent;
     private float f_nextTime;
     private float f_gridX, f_gridY;
     private int in_curFrame;
     
     
     public void init()
     {
         f_timePercent = 1.0f/(float)in_framePerSec;
         f_nextTime = f_timePercent;
         
         f_gridX = 1.0f/(float)in_gridX;
         f_gridY = 1.0f/(float)in_gridY;
         in_curFrame = 1;
     }
     
     public void updateAnimation(int _direction, Material _material)
     {
         // Update Material
         
         _material.mainTexture = spriteTextur;
         //Update Frame by Time
         
         if(Time.time>f_nextTime)
         {
             f_nextTime = Time.time + f_timePercent;
             in_curFrame++;
             
             if(in_curFrame > in_framePerSec)
             {
                 in_curFrame = 1;
             }
         }
         
         _material.mainTextureScale = new Vector2(_direction*f_gridX, f_gridY);
         
          int in_col = 0;
         if(in_gridY>1)
         {
             in_col = (int)Mathf.Ceil(in_curFrame/in_gridX);
         }
         
         if(_direction == 1)
         {
             _material.mainTextureOffset = new Vector2(((in_curFrame)%in_gridX) *f_gridX, in_col*f_gridY);
         }
         else
         {
             //Flip Texture
             _material.mainTextureOffset = new Vector2(((in_gridX+(in_curFrame)%in_gridX))*f_gridX, in_col*f_gridY);
         }
     }
     
     public void resetFrame()
     {
         in_curFrame = 1;
     }
 }
 

}

So, then i drag'n'dopped the Script to my Player-Object and looked up at the inspector. But at the ScriptComponent i just can see these two variables

F_Speed 5 In_Direction 0

No SpriteManager array called loopSprites which i can work with in the inspector. The Tutorialbook is telling me to go to "Loop Sprites" and to set the Size to 2 and then setting the Elements in a certain way.

Can someone please tell me, what did i do wrong. It must be somewhere in the Code.

I have to mention: The Tutorial-Code is written in Java-Script, i "translated" it into C#, cause i am more familiar with C# than JavaScript (please no wars about which language is better)
