Unity cannot use Vector3 error = confusion

Thanks a bunch robertbu.

Just for the sake of not making another question, I am getting this:

Object reference not set to an instance of an object

Even though I have set the object in the inspector.

Updated script:

 //Original Object
     var object : GameObject;
 
 //Object position + end poition modified
     var objectPos : Vector3;
     var objectEnd : Vector3;
 
 //Controllers
     var duration : float = 1.0;
     var startTime : float;
 
 //Barriers
     var topPos : float = 0;
     var rightPos : float = 5;
     var leftPos : float = 11;
     var bottomPos : float = 16;
     
     function Start () {
     
     startTime = Time.time;
     objectPos = object.transform.position;
     objectEnd = object.transform.position;
     
     }
 
     function Update () {
  
     if (object.transform.postion.x <= rightPos) {
  
         objectEnd.transform.position.x = 4.797853;
  
         object.transform.position = Vector3.Lerp(objectPos, objectEnd, (Time.time - startTime) / duration);
 
         }
 
     }

The typical reason you get an "object not set set" error when you can see the value in the Inspector is that you have the script attached to more than one object, and it is not initialized on the other object. Use the search box in the upper right in the Hierarchy window to search out other game object with this script.

I had considered that and I found that only one object in the scene was assigned the script. When I turn the script off, the error disappears. Also, the script doesn't seem to work. Is it because of the error?

I took a deeper look at your code and found two problems. The first is on line 28. You misspelled 'position'. On line 30, 'objectEnd' is a Vector3, not a GameObject, so you would code it:

 objectEnd.x = 4.797853;

Both issues would have generated an error if '#pragma strict' was at the top of the file.

Sorry, it should be objectEnd.x:

 #pragma strict
 //Original Object
     var object : GameObject;
  
 //Object position + end poition modified
     var objectPos : Vector3;
     var objectEnd : Vector3;
  
 //Controllers
     var duration : float = 1.0;
     var startTime : float;
  
 //Barriers
     var topPos : float = 0;
     var rightPos : float = 5;
     var leftPos : float = 11;
     var bottomPos : float = 16;
  
     function Start () {
  
     startTime = Time.time;
     objectPos = object.transform.position;
     objectEnd = object.transform.position;
  
     }
  
     function Update () {
  
     if (object.transform.position.x <= rightPos) {
  
        objectEnd.x = 4.797853;
  
        object.transform.position = Vector3.Lerp(objectPos, objectEnd, (Time.time - startTime) / duration);
  
        }
  
     }
