Sigma Binary

 

This mod will let you turn custom and/or stock bodies into binary systems,

without the need to do all the calculations yourself.

This also will allow any user to decide between playing with or without binary systems.

You only need to add the SigmaBinary {} node to the Secondary Body of your system. All the other settings are optional.

How to install this mod

  1. Download the mod (link found in the "Downloads" section)
  2. If you have an old installation delete the folder "Binary" found in GameData\Sigma\
  3. Install the mod by merging the GameData folder from the archive with the one in your KSP install.

If you want to add this to your mod

  1. Add the node "SigmaBinary" to the secondary body of your binary system.
  2. Put a link to this mod into your thread so people may choose to download this mod if they want binary systems.

 

Other Questions

- Can I move the Sun?
No.

- Will this mod mess up Stock Planets?
No. This mod doesn't add any binary system at all.

- Can I bundle SigmaBinary into my mod?
You are free to (= I encourage you to) make your mod compatible with SigmaBinary, however I would rather if you didn't redistribute my work.

- Is it possible to create ternary systems?
You can create some multiple systems but it's a little harder to set up, feel free to ask for more info in the thread. 

- Is this mod compatible with RSS?
Yes, RSS has had built in SigmaBinary support for a while.


I'll put in here any frequent question I receive.
If you have any question about the mod feel free to post down here or PM me.

Lol.

Go home physics, you're drunk!

Sorry, if that's considered inappropriate, but it fits - am I right?

looks like there is a problem with time warp and those planets not following the orbits, but I can't say much from that image :D

any chance you can pm me the configs of those bodies and the template you used to make the system binary?

Just something whacky I noticed while trying to understand Kopernicus - it is likely just this timewarp issue that occurs from time to time for no apparent reason, I did not even manage to reproduce it. I have seen something similar at least with OPM, so you are completely innocent :P

I had similar bugs all the time when developing pluron-khato.

There are a couple of things you may try:

1- if you used hyperedit to move your vessel to that planet, once you are there quick-save and quick-load.

This is to prevent an hyperedit bug

2- if in the settings for the planets there is anything negative (like longitudeofascendingnode or inclination or whatever) that may be causing issues

I usually use kittopia to save the bodies stats after they are loaded on ksp. If you this make sure you remove the files generated in the saveload folder otherwise they'll bug your game

thank you for the feedback ;)

and the nice pics :D

Cool binary system! I would love to see that in a mod.

I don't know which bodies are those in Tellion's pics,

I've made a Pluto-Charon analogue which you can download here.

my skills in designing planets are not that great tho.

that's why I decided to make this mod, so that people can make binaries with almost zero effort :D

have you tried the Duna-Ike binary config?

Some custom planets I made the last two days to get some basic knowledge of Kopernicus. They are rather generic space engine clones and the forum is littered with those anyway, so they will not be released - the screenshots are the flattering ones too. Using EVE layers to fake a nice atmosphere from space and ground usually comes with some nasty side effects while transitioning between the two that I have not been able to get rid of. Scatterer will make this approach obsolete anyway...

I just posted because I was delighted that this mod saved me doing all the math myself, and doing it over and over again everytime I wanted to create something similar :)

I agree on the zero effort part. Combine that with Windows 10 and Cortana, I have no excuse to leave my room.

This is exactly what I was aiming for: easy to use for both players and modders.

players can turn every planet-moon combination into a binary system and modders can implement binaries without forcing players to play on a binary if they don't feel like it.

I haven't tried it with every existing planets pack, but as far as I know this should be compatible with all of them.

So if you enjoy a specific planet pack and want them to add binaries, make sure they know about this mod ;)

can you make it so there can be more then 2 bodys orbiting around the barrycentre eg: the joolian system

Yes, though Duna-Ike is kinda glitchy for me though :/

I was just telling Tellion that his binary system looked cool.

what is glitchy about it? works fine for me

I'm not sure what you mean by Joolian system.

If you mean Jool with it's 5 moons, the mass of Jool is so high that you probably wouldn't notice the difference between stock ksp and everything around a barycenter.

Anyways, KSP has some limitation that make doing weird stuff not that easy. So if you want to make a system with 5 planets of the same mass, you will have a lot of problems flying in there since KSP don't handles sphere of influence very well for those bodies.

Now that I think about it It may be possible to do something like this

But I doubt anyone would recognize it :)

and here's a sneak peak

Great.. wrong thread!

hmm what?

this thread is getting more confusing every day

Poor Sigma, so many offtopic comments :D

Coming to the rescue: Is the secondary always at the same distance from the barycenter?

damn tellion, I never read this comment :D

to answer your question:

the distance will be fixed only if the eccentricity of the secondary is equal to 0

otherwise you will have a different distance between the primary and the secondary depending on which point of their orbit they are.

what will never change is the ratio between the primary distance from the barycenter and the secondary distance from the barycenter

since that's defined by the mass ratio of the two bodies (which is fixed of course)
