[QUOTE=Fimbul] But there will be a way to group different objects, right?
I can think of a couple situations in which that'd be useful, such as when you want to create/destroy/rotate/move an entire composite object at once.
It would automatically associate all instances with each other (for instance, a condition that selects one object would include all objects of that group into the SOL).
That would enable things like a tank emitting smoke particles, complete with a main cannon and a machine gun turret, with a health bar and a player name (for instance).[/QUOTE]
What you want and are describing are containers, which are on the to do list. Or the pairer object, which can make containers at runtime, though that also hasn't been implemented yet.
