So, I want my space station to be spinning in space, like a real space station would. Does anyone know how to do this? I checked out VFIG's spinning skybox, but even copy/pasting it into my map doesnt work. His uses a system of physboxes and a physmotor spinning the sky_camera in a skybox textured box, in the 3d sky. However, when I load up the map, only the top portion spins, and it is heavilly distorted and stretched.

I'm too busy, I can only say two things:

1. People who use physics to make generic rotating stuff make me rage. Such an enormous waste of cpu. Try a rotating door.

2. "like a real space station would" wat.

would it work if you parented your skybox brushes to something else in the middle of the map, that's rotating? too busy to test, srry if it doesn't work, if it does PM me, and I'll congratulate myself

Real space stations don't rotate fast enough that you can watch it. It's more along the speed of watching the tide go in or out. It'd be a neat effect though.

The real space station (we only have 1 to my knowledge) is in zero G (lack of gravity, not the map). :facepalm:

For there to be artificial gravity, it would need to rotate so that the centripetal force is equal to G (-9.81 m/s/s).

Sorry for the non-topic post, but I'm a physics major. It irked me a little.

Well, since this "station" does have artifical gravity, it should rotate then! Haha booj!

Anyways, problem still stands. I dont see how terowick's plan would work, since no matter how much you rotate skybox brushes, the skybox stays in the same place.

You may have to take matters into your own hands, so to speak, and texture the insides of your 3D Skybox cube, not with the skybox texture, but with the individual textures of your chosen skybox.

In theory you'd be unable to tell the difference.

Uh, no. You would see it. Really obviously.

IDK, it worked here, though for whatever reason its not working for me.

Just replace the phys_motor with a func_door_rotating set to rotate 9001 degrees.

It could be constantly propelling itself up.

I thought centripedal force creating gravity wasn't actually possible. Don't want to debate a physics major, though, I am way outclassed here.

Correct. You'd need centrifugal force force for that.

Have you tried what Tapp suggested? That's the most obvious way I can think of.

Lul

+10 to you sir.

Yes, that would work also, but it wouldn't be really plausible

Good call. Though, I did kinda fudge that definition. To create "artificial gravity" you would need to something like a large wheel, and to feel the 'gravity' you would need to be walking along the inside edge of the wheel (as in the above comic, were Mr. Bond is tied)...

Its actually not very hard to do...

It just like most other sciencey things, cost a metric ton of money, all limbs and your first born. (That is, to build a space station like described)

So this might be entirely impossible, because it might not matter how the texture is rotated, the skybox texture shenanigans might override it, but could you make a cube textured skybox around the map a func_brush and rotate it (with parenting), then seal the map with nodraw like you would an optimized skybox?

only one way to find out

Totally plausible. Just spin around in circles. It'd work, unlike centripetal force, and it produces a large area of gravitationally affected ground, unlike centrifugal force.

Isn't that what I said?

@nerdboy:
Wouldn't it have to be constantly accelerating? Because if it's simply moving up at a constant rate you wouldn't notice it once your inertia levels out or whatnot. I mean not only is the earth spinning REALLY fast but the entire solar system is whizzing through the universe even faster, but we don't notice it because it's a constant rate and we go right along with it.
