A small Node.js application that monitors your Lost Ark queue and notifies you when it's your turn to play! It even works when Lost Ark is running in the background (see Limitations)!

It's pretty simple: it takes a screenshot of your monitor and use OCR to recognize keywords that should be present on the screen when you are in character select. Pushbullet integration gives you a notifcation straight to your device!

There's no automation at play here!

1. Download and install Node.js

2. Clone this repo (or download the zip)

3. a. Open a terminal and cd to the downloaded folder and run npm install.

   b. See Easy Mode below

If you are not familiar with command lines, you can use the batch scripts in the bin-folder. Just double-click the quickstart.bat and it will install dependencies and run the program. If you want PushBullet notifications, run quickstartSetup.bat instead. This will run you through a wizard to get PushBullet up and running.

1. Open a terminal and cd to the folder of this project.
2. node index.js or npm start

See CLI options for more arguments.

By default it takes screenshots of Lost Ark, and plays an alert when it thinks you are in Character Select screen.

Ideally, you should try running the program on a character-select screen, and verify that it recognizes that you are not in a queue. You can also use the dry command below to check that notification sound works (note that this may be loud).

To get notifications to your device:

1. Make a Pushbullet-account (one-click signup with google and facebook).
2. Go to your Account and click 'Create Access Token'.
3. Open config.json and paste in the API-key under PUSHBULLET.API_KEY.
4. Download Pushbullet to your device. Android. iOS.
5. Start the program with npm start, and follow the interactive device-selection.
6. Run npm run dry to do a dry-run and test your setup.

The user configuration-file is located in config.json. If you haven't run the program yet you can create it or just modify default.config.json.

PUSHBULLET - Contains parameters for pushbullet integration. See Notifications.

PLAY_SOUND - A path to a mp3-file to be played when character selection screen is shown. Can be an absolute-path, or relative to the project. If empty or false, no sound is played.

CHECK_INTERVAL - Time in ms between every screenshot and queue-check. Default: 30000 (30 sec).

UPDATE_INTERVAL - Time in ms between every position notification update. Default: 180000 (30min).

POSITION_THRESHOLD - Queue position threshold for sending a notification regardless of UPDATE_INTERVAL. If your position is lower than this, a notifcation is sent. Default: 200

PIXEL_THRESHOLD - Threshold used to make it easier for OCR to recognize text. Any pixel value greater than or equal to the threshold value will be set to 255, otherwise it will be set to 0. This means we create a high-contrast "black and white"-image. Adjust this if the OCR has trouble recognizing the text on your screen.

Do a dry-run, which 'simulates' queue completion. Use this to test notifications-setup and get sample images of Lost Ark. Note that the volume may be loud!

Do not play a sound when queue is complete.

Rerun first-time setup. E.g change PushBullet-device.

Sets log level to debug. Also outputs the processed image the OCR uses for recognition to processed.png, and the raw screenshot to screenshot.png.

• Lost Ark should preferebly be running in windowed or borderless windowed mode. The screen-capture does not work if running in Fullscreen and the window is minimized. This is due to the render-loop being paused, and there's no way around that.

• There has been very limited testing. I created this for myself, based on code I wrote for the same purpose for WoW Classic release. I have not tested on different monitors, resolutions or other versions than Windows 10. Please raise an issue if you face bugs.

• Character/roster wallpapers may have an effect on the matching when logged in. I've only tested on the default and founder-pack one.

• The client must be english. Support for other languages should be possible, but I need screenshots (and the words in text-form) for both queue-screen and character select screen.

• I'm using edge-js to be able to run C#-code that takes the actual screenshot. This requires .Net framework - most Windows installations hopefully has this already, but it can be downloaded from here if you face issues: https://www.microsoft.com/en-us/download/details.aspx?id=30653

• Only Windows is supported, but that should hopefully not be a problem, since Lost Ark only supports Windows anyway!
