Setting the transform of an instantiated game object

Question

Hello! I am new to posting on Unity Answers, though I have been stalking the threads for answers to my problems for quite sometime now... ;)

I am having an issue setting the transform of a game object that I have already instantiated. Now I've seen several threads already where people have similar issues, but they are all trying to change the transform of the prefab. I have instantiated the prefab into a variable and I am trying to change the transform of that variable. Here is the bit of code that I am talking about.

 var single : GameObject;
 private var temp:GameObject;
 
 temp = GameObject.Instantiate(single, location, single.transform.rotation) as GameObject;
 temp.transform.parent = transform;

The really frustrating part is that I'm doing this somewhere else in my code (what I believe to be the exact same thing) and it works. This one however....does not.

Also, the exact error I am getting:

"Setting the parent of a transform which resides in a prefab is disabled to prevent data corruption.

UnityEngine.Transform:set_parent(Transform)" Thanks a lot for any help!

Just giving it a once over it seems like this might be the type of line that you're looking for.

     temp = GameObject.Instantiate (single, transform.position, transform.rotation) as GameObject;

But is "location" in your above code another variable that you haven't written down above next to single and temp? I'm not really sure why that's there. :P

Yes, sorry. This object is replacing another object. Location is the transform.position of the old object. Single.transform.rotation is used to make sure this object is rotated to the same angle that the original one is rotated to.

I was messing around with something like this earlier and figured out how to do this when we get the error

Setting the parent of a transform which resides in a prefab is disabled to prevent data corruption.

We have to essentially create another instance of the object and assign it at runtime once the prefab has been instantiated. So something like this (C#)

 public Transform prefabParent;
     
 public GameObject myPrefab;
 private GameObject runtimeGO;
      
 void OnEnable ()
 {
      //Instantiate the prefab and assign it to the runtime GameObject
      runtimeGO = (GameObject) Instantiate(myPrefab);
      
      //Assign the position of the transform for the runtime GameObject
      runtimeGO.transform.position = gameObject.transform.position;
 
      //Assign the parent of the runtime GameObject
      runtimeGO.transform.parent = prefabParent.transform;
 }

Was that kind of what you were looking for?
