Thank you so much. When it started working, i just jumped for joy

I don’t think the video tutorial I am using works. I keep typing in the code just like he does but it doesn’t seem to work
Here is the link:
[ ](https://www.youtube.com/watch?v=KIBQqCSGXmM)
Here is the code I made from it at around 14 minutes
using UnityEngine;
using System.Collections;
public class CameraBehavior : MonoBehaviour {
Transform player;
public float horizontaloffset = 6f;
// Use this for initialization
void Start () {
player = GameObject.FindGameObjectWithTag (“Player”).tranform;
}
// Update is called once per frame
void Update () {
var x = player.position.x;
transform.position = new Vector3 (x + horizontaloffset, transform.position.y, -10);
}
}
And here is the error it gave me
Assets/CameraBehavior.cs(11,70): error CS1061: Type `UnityEngine.GameObject' does not contain a definition for `tranform’ and no extension method `tranform' of type `UnityEngine.GameObject’ could be found (are you missing a using directive or an assembly reference?)

**PLEASE** , always use code tags when posting source code.
Also, you wrote “tranform” instead of “transform.” You should get familiar with code completion.

im sorry, how do i put a code tag?

[code]Put your code here.[/code]
You will need to remove the spaces for it to show up. Here’s what it looks like without the spaces inside the code brackets.
```auto
Put your code here.

Errors:

I am stumped on this, i did what the tutorial said to do and I’m just not sure what happened. Anywho, I hope i put the code tag right

When you get the error _An object reference is required to access non-static member_, this means you need an instance of the object to use this member. Rigidbody2D is a class, not an object of this class.
Add a variable `private Rigidbody2D m_Rigidbody;` then in your Start() method, set this to the attached Rigidbody2D like this `m_Rigidbody = GetComponent();` and finally replace Rigidbody2D.velocity and Rigidbody2D.AddForce with m\_Rigidbody.velocity and m\_Rigidbody.AddForce.
You can now also replace gameObject.GetComponent().[velocity](http://unity3d.com/support/documentation/ScriptReference/30_search.html?q=velocity) with m\_Rigidbody.velocity. It’s good practice to store this in a variable so you don’t have to call GetComponent all the time.
