Loading a list into unity
I need to load the list of objects positions and execute it. But I can't figure it out. I already got the save system working, it saves all the gameobjects into a list into a .xml. I can load the objects. I just don't know how to make it so all the objects are positioned where the save data says to position them.

List<SaveStructure.GameItems> _GameItems;
GameObject[] bodies;
string _data = string.Empty;
Vector3 VPosition;
void Awake()
{
_GameItems = new List<SaveStructure.GameItems>();
}
// When the EGO is instansiated the Start will trigger
// so we setup our initial values for our local members

_LoadMSG = new Rect(10, 140, 400, 40);
// Where we want to save and load to and from
_FileLocation = Application.dataPath+"/";
