|source||Instance object for which you want to find the corresponding prefab asset object.|
Object The corresponding asset object or null.
Returns the corresponding asset object of
source, or null if it can't be found.
Use this function to get a prefab asset object the
source was instantiated from.
This also returns the corresponding object from the prefab asset if the prefab instance has become disconnected, which can then be used to reconnect the prefab instance to the prefab asset.
