The Logic World Dedicated Server (LWDS) allows Disciples of Bobby to create circuits together.
[[File:Logo alt square.png|thumb|Icon for Logic World Dedicated Server]]

== Required Specs ==

The required machine to run a Logic World server depends a lot on the complexity and amount of circuits you build in the world and how many players will be using it at the same time.

For a couple of players, a 4gb server is plenty.

== Linux (Ubuntu) ==

This guide assumes the following:
* Ubuntu 24.04 has been freshly installed.
* The server has a public IP Address

==== Update and Install Packages ====

Enable 32-bit packages 
<code>sudo dpkg --add-architecture i386</code> 
Enable multiverse repositories 
<code>sudo add-apt-repository multiverse</code> 
These two commands allow steamcmd to be installed which is the tool used to install the Logic world server software. 
 
Update the system 
<code>sudo apt-get update</code> 
<code>sudo apt-get upgrade -y --no-install-recommends</code> 
 
These update your package manager and install updates for any installed packages. 
 
Install new packages 
<code>sudo apt-get install -y --no-install-recommends steamcmd screen ufw</code> 
 
<code>steamcmd</code> is used to install Logic world. 
<code>screen</code> is used to keep Logic World running even if you close the terminal. 
<code>ufw</code> is used to control the firewall. 
 
Allow connections for Logic World in the firewall 
<code>sudo ufw allow 43531/udp</code> 

==== Setup a Logic World User ====
We are now going to create a user that will run the logic world server. 

Create the user: 
<code>sudo adduser logicworld</code> 
This is start a wizard to guide you through creating the user, the only important setting is the password, all other settings can be left blank. 
 
Switch to the User: 
<code>sudo su logicworld</code> 
This command will make you the new user you just created. If you would like to switch back to your initial user type <code>exit</code>. For now, stay as the logicworld user, all the following commands need to be run by them.

==== Install Logic World Server ====

Make sure you are currently in your home directory. 
<code>cd</code> 
 
Create a directory where we can install logic world. 
<code>mkdir -p /home/logicworld/logic_world/logic_world_ds/</code> 
Everything for Logic World will be placed in the logic_world folder, logic_world_ds will contain the logic world server software.
 
Use steamcmd to install the Logic World server, make sure to replace <USERNAME> with your steam username. 
Note: this is not the same as your display name, to find your username in Steam go to Help > Steam Support. This page will display "What do you need help with, <USERNAME>" 
<code>steamcmd +force_install_dir /home/logicworld/logic_world/logic_world_ds/ +login <USERNAME> +app_update 1252670 validate +quit</code> 
 
If you want to run the exciting but unstable public-preview version of Logic World, run the following command instead of the previous one
<code>steamcmd +force_install_dir /home/logicworld/logic_world/logic_world_ds/ +login <USERNAME> +app_update 1252670 -beta public-previews validate +quit</code> 
Make sure all connecting clients are also running public preview or they will be unable to connect. 
 
If it is your first time running steamcmd, you will be asked to login to your account. 
If you are using the Steam Guard app and the server is hosted in a different location to where you currently are it may refuse to let you log in. 
One way to get around this security measure is to use a VPN on your phone in the same area the server is hosted in. (Eg, I setup my server in cloud hosting based in Singapore, so used a VPN to make it look like my phone was in Singapore) 
 
==== Configure your new Server ====

Create a shortcut to the Gamedata folder 
<code>ln -s /home/logicworld/logic_world/logic_world_ds/GameData/ /home/logicworld/logic_world/GameData</code> 
 
Change the default password. 
This command will change the password to <code>12345678</code>, modify this to set your own password. 
<code>sed -i 's/this is a very secure password/12345678/g' ~/logic_world/logic_world_ds/config.jecs</code>
The config file is located at <code>~/logic_world/logic_world_ds/config.jecs</code> you can use vim or nano if you want to customize it further. 

==== Create Management Scripts ====

Create the start up script 
<code>printf "#!/usr/bin/env bash\n\nscreen -L -m -d -S lwserver \$(find /home/logicworld/logic_world/logic_world_ds -name 'net*' -type d | head -1)/Server\n" > ~/start_lw_server.sh</code> 
Make it executable 
<code>chmod +x ~/start_lw_server.sh</code> 
 
Create the update script 
Make sure to replace <code><USERNAME></code> with your username, same as you did when installing the server. 
<code>printf "#!/usr/bin/env bash\n\nsteamcmd +force_install_dir /home/logicworld/logic_world/logic_world_ds/ +login <USERNAME> +app_update 1252670 validate +quit\n" > ~/update_logic_world_server.sh</code> 
Or, it you are using the public-preview version use this to command instead. 
<code>printf "#!/usr/bin/env bash\n\nsteamcmd +force_install_dir /home/logicworld/logic_world/logic_world_ds/ +login <USERNAME> +app_update 1252670 -beta public-previews validate +quit\n" > ~/update_logic_world_server.sh</code> 
 
Make the update script executable 
<code>chmod +x ~/update_logic_world_server.sh</code> 

==== Start the Server ====
To start your new server run this command. 
<code>./start_lw_server.sh</code> 
This will start the server in the background, if you are able to connect to the server with your Logic World game you can now disconnect from the server. 
 
If you need to log in again to make changes make sure to run <code>sudo su logicworld</code> to switch to your user then run <code>cd</code> to go to your home directory. 
From here you can: 
Start the server: <code>./start_lw_server.sh</code> 
Update the server: <code>./update_logic_world_server.sh</code> 
View the output of the running server: <code>screen -r</code> 
To stop viewing the running server output press <code>ctrl+a</code> then press <code>d</code> 
If you would like to stop the server instead, press <code>ctrl+c</code> while viewing the output.
