What are "groups"?

[Vectorial1024]

Was cross-checking between what I saw in the unpacked mission director files and the official mission director guide https://www.egosoft.com:8444/confluence ... ctor+Guide

What even are "groups"?

I notice the following:

Code: Select all

<create_group groupname="$x" />

<add_to_group groupname="$x" object/list/group="" />

<remove_from_group group="$x" object="$x"/>

<destroy_group group="$x"/>

Yet, this is not even directly mentioned in the mission director guide. The guide only hinted "groups" in the explanation of tables:

Lists, tables, groups and buildplans cannot be used as table keys

Is this just a data structure like lists and tables (i.e., "group" is equivalent to a set) or does this have other gameplay implications?
