OgarII

Your friendly agar.io private server recreation.

• It supports all current agar.io protocol versions.

• It supports handling multiple worlds, all within one instance. Be wary that you can still use up the one CPU core node.js is running on.

• It has a minimal memory footprint, and strictly uses uWebSockets for networking.

• The code uses JSDoc to specify types. Understanding what the code does is down to your understanding of English.

Notes

• Ask all your questions over on the Agar.io Private Servers Discord guild.

• Before connecting from agar.io you will need to do core.disableIntegrityChecks(true) in the console.

Running

1. Make sure you have node.js version 8 or greater.

2. Make sure you have a C++11 compliant compiler for building uWebSockets.

   • If you're on Windows, npm install -g windows-build-tools.
   • If you're on GNU/Linux, use your package manager to install a supported C++ compiler such as GCC.

3. Clone / download the repo.

4. npm install in /.

5. cd ./cli/

6. node index.js

Configuring

• After your first run, OgarII will drop two files in cli/ / working directory: log-settings.json and settings.json.

• To change how OgarII runs, modify cli/settings.json.

• To change what gets logged, modify cli/log-settings.json.

Expanding

• To create your own commands, check out src/commands/CommandList.js on the command API. To add it to the CLI use ServerHandle.commands.register, and for chat commands use ServerHandle.chatCommands.register.

• To create your own gamemodes, inherit src/Gamemode.js's Gamemode abstract class, modify event handling to your wish, then add it with ServerHandle.gamemodes.register before the handle starts.

• The ServerHandle class is standalone, which means that you can completely ditch the cli/ folder, require("./src/ServerHandle.js") and do whatever you want with it. OgarII is also available as an npm package for this exact purpose.
