Instantiating from an object that's in an array

Question

Hi there, basically what I want to do is to instantiate a platform from the position of an object that's in an array.

Psuedocode

 var platform : Transform;
 var g:GameObject[];
 Instantiate (platform, g[5].position, g[5].rotation);

That's the general idea I had, but trying it out just threw up the error that it has a null reference (NullReferenceException: Object reference not set to an instance of an object) even though you can see the GameObject at position 5 in the array quite clearly on the screen.

Is there anyway of doing this?

Thanks

Position 5 will be of index 4, since indexes start at 0. Try g[4]. Also check to be sure your indexed object is not null. If it is, send a message to the log. Also, be sure to use a new instance of your object by using some "Clone". You also need to use the Transform of g[4] in order to get its position, since it is a GameObject.

 if(g[4] != null)
 {
     var Clone = Instantiate (platform, g[4].transform.position, Quaternion.identity);
 }
 
 else if(g[4] == null)
 {
     Debug.Log("g[4] doesn't seem to be assigned!");
 }

Worked great, I think the problem was that I hadn't added the "transform.position" to the position variable in the Instantiate part.
