Fabric

This guide describes how to configure MSCS to run a world using Fabric.

There are several ways to install Fabric. This document describes the current recommended method, which uses an executable server launcher instead of a separate installer. Manual installation using an installer JAR is not covered.

Initial configuration

Download the server launcher into the Minecraft Server Control Script’s server directory.
Note: the URL in the following example will not work. You must use the curl command provided on the download page.
```
cd /opt/mscs/server
curl -OJ https://meta.fabricmc.net/v2/versions/loader/GameVersion/LoaderVersion/InstallerVersion/server/jar
```

When the download completes, it will tell you the filename that was saved. Take note of it (or copy it to your clipboard) for use in a future step.

Continuing the artificial (non-functional) example from the previous step…

$ curl -OJ https://meta.fabricmc.net/v2/versions/loader/GameVersion/LoaderVersion/InstallerVersion/server/jar
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
100  143k    0  143k    0     0   109k      0 --:--:--  0:00:01 --:--:--  109k
curl: Saved to filename 'fabric-server-mc.GameVersion-loader.LoaderVersion-launcher.LauncherVersion.jar'

Create a world. (Replace “fabric-example” with your desired world name here and in future steps.)
```
mscs create fabric-example
```
Configure the world to use the Fabric JAR by configuring some settings in mscs.properties.
Note: this uses the filename from the artificial example above. When you run the first command, you must use the filename that you observed in step 2 instead of this example’s artificial filename.
```
echo 'mscs-server-jar=fabric-server-mc.GameVersion-loader.LoaderVersion-launcher.LauncherVersion.jar' >> /opt/mscs/worlds/fabric-example/mscs.properties
echo 'mscs-server-url=' >> /opt/mscs/worlds/fabric-example/mscs.properties
```

Accept the EULA.

echo 'eula=true' > /opt/mscs/worlds/fabric-example/eula.txt

(optional) Customize your world’s settings in mscs.properties and server.properties. See Adjusting World & Server Properties to learn about MSCS-specific settings. The Minecraft Wiki documents the settings that are configurable in server.properties.
Start the server.
```
mscs start fabric-example
```

Updating

To update, repeat steps 1 and 2 above. Then, change mscs-server-jar in your world’s mscs.properties to the updated version’s filename. Finally, restart your world.
