Snap object to vertex group in-game?

Hi
Is it possible to define a vertex group on an object and in-game have another object snap to its location?
For example, if I have a cube and whenever it spawns into a scene I will create an empty and have the empty snap to a vertex group that the cube has?
Thanks

what is your goal? attachment points?

is there an animated armature?

if the points are static, just use an offset vector local

to get a local from a point in space
point = someVector
local= point-object.worldPosition
local= object.worldOrientation.inverted()*local

this way you have a point local to an actor

you can go the other way as well

worldLocal = object.worldPosition+(object.worldOrientation*local)
