Factorio Forums

Hello everyone, I have Factorio on Steam and much to my disappointment I've found that it is impossible to play the game and run the server.bat file at the same time. I would like to be able to play on my own headless server with the same computer running it.

I think this issue was talked about before but I have not seen it show up on the bug reports section of the forums.

If you want to do that, you have to change the portfor the client side of Factorio.
Maybe this can help : viewtopic.php?f=11&t=13634&start=10#p93014
[Edit] : this one is even better : viewtopic.php?f=53&t=20811#p130869

The second link is a great resource, but how do I start a server with parameters? Thanks for your help by the way.

Hi,
You may find the help you need :

and here : https://wiki.factorio.com/index.php?title=Multiplayer

I'm sorry I can't be much more helpful, I have never set up a server, I'm the kind of solo guy (I always shoot first ^^).

Start Factorio normally and create a new game. Save the game, such as servermap

Copy C:\Users\<username>\AppData\Roaming\Factorio\config
to
C:\Users\<%username%>\AppData\Roaming\Factorio with a different name of course such as config-server
So there will be in side Factorio folder a folder with config and config-server

Inside config-server folder edit config.ini

write-data=__PATH__system-write-data__
to
write-data=__PATH__system-write-data__/server

Navigate to where base game is installed

For steam:

C:\Program Files (x86)\Steam\steamapps\common\Factorio
Create a new folder where the server files will reside such as on the Desktop called Factorio Server
Inside the folder copy contents of C:\Program Files (x86)\Steam\steamapps\common\Factorio

In Factorio Server folder edit config-path.cfg
config-path=__PATH__system-write-data__/config
to
config-path=__PATH__system-write-data__/server

Navigate to \Factorio Server\bin\x64

Create new text document, add the following:
cd "\\Factorio Server\bin\x64"
start /wait factorio.exe --start-server "servermap.zip"

save file as filename.bat
*remember to save file type as all files

copy servermap.zip file to this location,
this should be located at C:\Users\<username>\AppData\Roaming\Factorio\saves

run .bat file
this will open command prompt with server running
you should be able to run Factorio normally

latest guide kinda works but for me its few bits were diffrent like - there was no config file in appdata/roaming but it was in game folder, then it kinda worked but created own save somehow and loaded no mods so i just copy saves and mods folders to game server folder and all good
