Switch the prefab of a game object from a script

If I drag&drop a prefab onto a gameobject in the hierarchy while holding the alt-key, the gameobject will be replaced with an instance of that prefab, while maintaining its name and transform. How can I do this in script?

http://www.unifycommunity.com/wiki/index.php?title=ReplaceSelection does something like this

The way that script works is by instantiating a new copy of the prefab, copying over the name and transform, and then destroying the object. Unfortunately, this won't work for me, as other objects are referencing the object to be replaced. Additionally, under some circumstances the prefab will be switched while the object is actively being moved, and even DestroyImmediate() won't destroy an object while it's being moved.

Hence 'something like' ;)

leave the blank gameobject as a parent to the object you intend to replace.

when you wish to change it, have your script destroy the child object then:

instantiate the replacement,

parent

local rotation and local position set to "0"

and you're done
