Extremely simple/stupid, but functional, shared save file solution

[spiritplumber]

I wrote this.

It works.

I own emlia.org so feel free to use it.

Save this as ftpsync.bat or something like that, and put it in your KSP folder.

I want to next make a plugin that autosyncs based on when Space Center is entered, but will only do so if this is useful at all. If this gets used, I can see if the server can take the load.

Thanks in advance.

I have nothing witty to say.

This is a more granular version, which syncs when stuff happens in game. It uploads a persistent file every time it changes, and downloads when you first load the game OR when you exit to the main menu so that you can load a game. This makes it so you don't have to get out of KSP.

The two are compatible.

I recommend using the first one for playing when there is a great distance in time between turns, and this one for playing turn-based, like in the Battle for Laythe video.

So... what does it do? Does it synchronize saves across different computers? In that case... AWESOME!

[spiritplumber]

Yes, that is what it does.

However, I wrote a better one, in the meantime. The two are compatible.

http://emlia.org/ksp_shared/ You can even see what people are doing.

This one is a bit more bandwidth intensive, but more granular.

Copy and paste it into ftpsync.bat or similar, and run in the KSP folder.

You should have a premade save...

if exist ftpsync.txt goto init

echo You have never run this script, so a settings file has been created.

There is a catch: the save game can have NO space character.

[Mein_Gott]

please write more about this, dont make me do any assumptions; im already sensing awesome

[spiritplumber]

So... what does it do? Does it synchronize saves across different computers? In that case... AWESOME!

Yep, basically. It seems to work.

Yes, that is what it does.

[Gristle]

It's not synchronizing, but more like facilitating sharing of saves. You probably should not have multiple people playing using the shared save at the same time as whichever save is uploaded last will be the save game used. This would work to help people who want to play in turns or shifts using the same persistence file.

This is in fact the intended use yes
