Simple Instructions: 1.3 Setup (MC 1.16.5 or older, Windows, Restart Script)

In this example, we suppose, that you installed the Minecraft server in the directory "C:\servers\Minecraft Server\" and use the Minecraft version 1.16.5 and the Forge version 36.2.23.

First, you create a file named restart_start.cmd in the "C:\servers\Minecraft Server\" directory.
Next, you insert the restart start script into the restart_start.cmd file:

cd "<Path of your Minecraft server>"
start .\restart_loop.cmd

In our example, the Minecraft server is in the directory "C:\servers\Minecraft Server\" installed and the restart_start.cmd file would look like this:

cd "C:\servers\Minecraft Server\"
start .\restart_loop.cmd

As a third step, you create a file named restart_loop.cmd in the "C:\servers\Minecraft Server\" directory.
Next, you insert the restart loop script into the restart_loop.cmd file:

echo OFF
:start
    java -Xmx<Amount of RAM in gigatytes you want to allocate to Minecraft>G -jar forge-<Minecraft version>-<Forge version>.jar
    SET /p should_restart=<./auto_restart/restart
    if %should_restart% EQU 0 goto stop
    echo If you want to stop the server completely, press STRG-C, \before the countdown is at 1!
    echo Rebooting in:
    timeout /T 5 /nobreak
    echo 'Server restarts!'
    goto start
:stop

In our example we give the Minecraft server 6 GB RAM to use, with Minecraft version 1.16.5 and Forge version 36.2.23 it would look like this:

echo OFF
:start
    java -Xmx6G -jar forge-1.16.5-36.2.23.jar
    SET /p should_restart=<./auto_restart/restart
    if %should_restart% EQU 0 goto stop
    echo If you want to stop the server completely, press STRG-C, \before the countdown is at 1!
    echo Rebooting in:
    timeout /T 5 /nobreak
    echo 'Server restarts!'
    goto start
:stop

Last, we have to feed the configuration file named auto_restart-server.toml. It is located in the world\serverconfig directory in the installation directory of your server. In our example, is in the directory "C:\servers\Minecraft Server\world\serverconfig".
In the config file, we have to set use_external_restart_script to true;

In our example, it would look like this:

#Options for restarting:
[restart]
	#Is the server started by an external restart script?
	use_external_restart_script = true
	#Command that is executed on Server stopped to restart the server. Only called if "[restart, use_external_restart_script]" is false.
	restart_command =  ""

Now we can start the Minecraft server and the Minecraft server restarts, if you use the /restart command.

After testing that the Minecraft server can restart, we continue configuring the features of the Auto Restart mod, starting with the mod naming Auto Restart feature.
