On demand server

BungeeCord plugin to start and stop minecraft servers when players are playing on.

This is a BungeeCord/Waterfall plugin that can execute a command when a player tries to connect to a server that isn't running.

Use case

You have a dedicated server or a VPS and you want to run multiple Minecraft servers on it while keeping the resource usage as low as possible.

Usage

1. Drop this plugin into your BungeeCord plugin's folder.
2. Start then stop the proxy once.
3. Open the plugin's config file and enter your servers address with their commands.

• Do not put a command that requires user interaction, the process will wait forever!

Current features/functioning

• Detect if a server is running on the server's port on the local machine.
• Start the servers if not running.
• Stops the servers if no players are on after a given delay (in plugin's configuration).
• Send customized player messages.

Permissions

Defects

• If the proxy crashes, the Minecraft servers might still be running but can't be controlled by the user nor the proxy.
