Show centre of mass of individual parts

[Bobe]

This mostly came about from wanting to position my external boosters such that the decouplers eject them smoothly rather than tilt and bounce off the rocket body*. Basically all I'm envisioning is a global tweakable to toggle "Show centre of mass", which would just display another floating ball, perhaps in green or red to differentiate, in the middle of that part.

*The issue of the booster separation can of course be solved with ullage motors, but I tend to avoid using them unless absolutely necessary as they are just a bit unsightly. Besides, the Sepratron and the motors in KW Rocketry are often too powerful when all they need is a gentle push (even limiting the thrust to 0% is too high). I feel like the decouplers themselves should be more powerful.

You could make a ship with just that part in it (If you can't start with the part, start with a command pod, attach the part to it, then set the part to root and toss the pod) to see the COM.

Make sure you empty the fuel from it to make sure you're looking at the correct spot.

Obviously, but I'd like to see the CoM while attaching the part to the ship. I thought this might be a simple enough plugin and that someone else might find it useful.

One issue I can see it that the mod would somehow need to detect what parts belong to the booster and which do not, since having the CoM for every single piece does not seem too useful.

That's something I was going to bring up, but wasn't sure if it was really necessary and I didn't want to make it seem overly complicated. But you're right, the booster itself isn't always the only thing attached to the decoupler. I was going to suggest being able to view the CoM of a subsection rather than the individual parts. So for example if you clicked on the booster and toggled the plugin, it would factor in all parts that are children of the selected part.

Just having the COM show for all disconnected collections of parts (if - of course - you have the COM indicator turned on) would be fine.

And yes I agree with you, I was just suggesting a workaround until someone writes a mod
