As I mentioned before, I'm looking across the board as to uses.
I'm sure GRG can use the help there in relation to his projects, it's just
a helpful side effect.
My idea pertains to other mechanoids, fighters, ships, etc.
Nothing from one particular series, movie, concept, etc.
Beam sabers are not the only thing out there that you can bludgeon an enemy with
on land, sea, sky, or space.

Thankfully.

Dropping back to Nuke's Gundam scripting example - that sounds like the best way to do it all around.
Wouldn't a simple use of the moving objects ability that was an extension of the turret scripting
(or something like that) be able to mimick say arm movements on a set track?
Maybe that's not a good example... ah...
Ok how bout if you spread the arms out away from the body, and you want them to wave
or repeat a motion - either reaching in or flexing up and down? Would that not be simpler?
Only thing then - might be that it would look rather silly if the unit stopped in place...

I guess it's all or nothing, it still would involve subobjects...
But I'm not going pure beam saber or heat axe or whatever from the Gundam universe(s).
I'm looking at options beyond that realm. It just happens to be in there with "beam saber"
because unless you say lightsaber or that other one... you have to go into a long winded explanation
on plasma swords and things to get the same concept out on the table for discussion.
Edit: takashi, thank you for mentioning it was possible due to your experimentation.
However I believe I would have to customize my weapons to suit my own purposes anyway.
