Zero G and movement


Rules Questions


From what I can tell, outside of magical/supernatural means of travel there are a limit amount of ways to travel.
You have the ability to 'climb' if there is enough hand holds with a DC 20 Athletics, you can also do so if you have a climb speed.
If you have a flight which provides its own thrust and doesn't require an atmosphere you can fly...
So what counts for that fly ability?
Wings (Unless specifically stated) and turbofans are mentioned require an atmosphere so they don't work. Jump jets do work... What about other armour upgrade or power armours with a fly speed? They don't specify how they truly work and are rather vague.

Wings work in zero g, but not in a vacuum.

That said, if you've ever seen a video of birds trying to fly in zero g, there are other problems with that.

So generally if it's not specified or described, then you can assume a fly speed lets you move in zero g and a vacuum.


Really should have specified that that, I am looking for in space

In general fly speeds should work. Jet packs, force packs, flying power armor, etc.

Wings don't. Everything else you have to use your judgment based on description.

Early stage barathus are one such question mark. They probably fly by expelling gas, which works in a vacuum. The only problem is where do they get more gas to expel? Are they using up environmental protections to do so? When their armor is adjusted to their physiology does it include gas vents for them to fly in a vacuum, or only in hostile atmosphere?

Based on how starfinder typically handles such situations, the answer is probably 'yes, let them fly, don't worry too hard about realism.'

Most people in space get around by walking on something, armor comes with clamps or something that let you walk without floating off.

I'd had the impression that they were using some form of telekinesis, since they are emphatically psionic beings.

What does that have to do with the price of tea in China?

The intent of the original question has to do with which types of flight are permitted in a vacuum. Your comment had to do with walking. I was asking what that had to do with the discussion in the thread.

For some reason, posting order and times seem to be wonky. The tea question was posted over a minute before my thought on Barathu flight, but somehow is listed after.

The original question asked about locomotion in a vacuum. Not just flight. They specifically listed climbing. One overlooked fact of spacewalking in starfinder is that armors have built in "you can clamp onto a surface and just walk features. If you're not somewhere you can clamp onto a surface I wonder what you're doing there..

Unless otherwise specified, the boots include a functionality that can anchor your feet to a solid surface in a zero-gravity environment, allowing you to orient yourself or return to normal footing when needed (for more about moving in zero-g, see page 402).

Climbing and a climb speed were mentioned in the initial post, yes, but the question was about flying.

I mean, technically, there's a limited number of ways to achieve any type of movement ;-)

But there are enough options for Zero-G movement that it shouldn't ever be a barrier to enjoying the game. If you're GMing and you don't want to fiddle with those rules, you can obviously feel free to handwave them. And if you're worried about playing in Society, I can't recall playing in a Scenario that didn't offer the players some basic solution to accomplish their goals.

There are several items that can help you here, too, in addition to simply breaking out cable line and a grappler:

Environmental (Zero-G) Clothing
Magboots
Falcon Boots

And HERE is what BigNorseWolf is talking about: "Unless otherwise specified, [armor] boots include a functionality that can anchor your feet to a solid surface in a zero-gravity environment"

One distinction that can help is Extraordinary ("Ex") flight versus Supernatural ("Su") flight.

Sarcesians, for example, have a Supernatural Fly Speed, and can use it in a vacuum. Barathu, in contrast, have an Extraordinary Fly Speed, which presumably wouldn't work in a vacuum, since their biology evolved in the atmosphere of a gas giant.

Monsters typically list whether their flight is Ex or Su, and most Class abilities and equipment descriptions do as well. It isn't 100%, unfortunately, so some will require adjudication. But for the most part, I've found it to be intuitive.

Sometimes people are looking for an answer but they don't phrase the question correctly. If someone asks "How do I pet the porcupine?" The exact answer is "Front to back, and avoid the ends of the quills, they've got scales that are sort of barbed and will stick to your hand no matter what". The right answer is "don't pet the porcupine they're probably going to gnaw off your finger..."

"I didn't tell you about this solution you didn't know about because you didn't ask about it" leaves out information that might be important. It's the difference between asking a search engine and fellow human(oid) beings.

Or, oh no, someone takes three seconds to read information not relevant to their exact situation or they miss information they might need. I'd rather risk the former than the later.


If you can walk on surfaces with your boots in zero g a climb speed is pointless - change you orientation and walk “up” the “wall”l.”

Sczarni

I can't find it now, but I believe you cannot Guarded Step with just Armor Boots on, and you move at half Speed. Or something similarly restrictive. Unless that was removed in an Errata, which might explain why I can't find it anywhere.

Looking it up on AoN, standard armor boots only let you anchor your feet to a surface in zero-g, "allowing you to orient yourself or return to normal footing when needed." Then a reference to the moving in zero-g rules, which require a move action and a surface to "grab" onto.

So this sounds like armor boots just allow you to stop/get rid of off kilter if you're adjacent to a surface, use a move action, and have both hands full. Only the both hands full issue seems like an actual benefit of the boots concerning active movement/stopping. The other passive benefit is that if you're anchored you get a bonus to your skill check not to get knocked off if someone bangs into you.

Magboots, a tech item, explicitly say they let you walk on metal surfaces at your land speed "without having to attempt skill checks" and you do not automatically move at the beginning of your turn each round (the usual "objects in motion remain in motion" part of zero-g movement rules). So they're greatly superior the built in armor boots (which require move to move, then move to stop, and you can't change directions while moving) and pretty necessary for effective zero-g combat in/on a ship or station.

Your justification of your comment is unnecessarily aggressive and confrontational. "I was trying to help" would have been sufficient. My general point is still that had you bothered to read the first three posts in full, you would have found that the OP clarified in full what they were looking for, which is what methods of flight work in a vacuum.

Sczarni

Put me in the camp of disagreeing that the only question being asked is about flight.

The thread title is "Zero G and movement", after all. Seems like the context of the initial post is asking about... Movement.

If it helps, my main focus was on flight but I am happy to receive every clarification. For example, if what I know is wrong, another method of moving I hadn't thought about/listed

Gasp! You mean those periods and question marks actually did have meaning? Who would guess such a thing?
