This script reads the logs for Arcaea-server's Link Play server, running in a systemd unit. It parses log messages for new rooms and sends a nicely-formatted message in Discord, announcing them and any players that join.

Unfortunately, Arcaea-server's Link Play server does not print log messages when the host of a room changes, or when players leave/the room is closed. Therefore, the messages sent by this webhook won't be edited if a player leaves or the room is closed.

1. Make sure that you're running the Link Play server seperately. Follow this guide to configure that.
2. Create a systemd service to run the Link Play server under.
   For example, in a file named arcaea-linkplay.service at /etc/systemd/system:

   [Unit]
   Description=Arcaea Link Play Server
   After=network-online.target
   Wants=network-online.target
   
   [Service]
   Type=simple
   User=arc
   WorkingDirectory=/home/arc/Arcaea-server/latest version
   ExecStart=/usr/bin/python3 run_linkplay_server.py
   
   [Install]
   WantedBy=multi-user.target

3. Clone this repository, then duplicate .env-example to .env, and edit the file with the name of your systemd service and the URL of your Discord webhook.

   git clone https://github.com/burritosoftware/arcaea-linkplay-webhook.git
   cd arcaea-linkplay-webhook
   cp .env-example .env
   nano .env

4. Install the requirements. Then, start the watcher, create a Link Play room, and verify that a message was sent.

   python3 -m pip install -U -r requirements.txt
   python3 watcher.py

5. If it all looks good, it's best to create a systemd service for this too, like arcaea-notif.service at /etc/systemd/system:

   [Unit]
   Description=Arcaea Linkplay Webhook
   After=network-online.target
   Wants=network-online.target
   
   [Service]
   Type=simple
   User=arc
   WorkingDirectory=/home/arc/arcaea-linkplay-webhook
   ExecStart=/usr/bin/python3 watcher.py
   
   [Install]
   WantedBy=multi-user.target
