Purchased Ogar?

If you've purchased a copy of Ogar, you've probably been ripped off. This post on our website explains why.

Obtaining and Using

If you are on Windows, you can download the latest binary build of Ogar from this page. The binary is the easiest way to get started running an Ogar server. If you'd like to tinker with the source code, you can follow the instructions below (and slightly modify them) to run the source on Windows.

As Ogar is written in Node.js, you must have Node.js, its "ws" and "vector2-node" modules installed to use it (unless you are using the Windows binary). You can usually download Node using your distribution's package manager (for *nix-like systems), or from the Node website. To install the "ws" module that is required, you can:

• for Windows, run Install Dependecies.bat located in the folder where this file is.
• for Mac, open your terminal, go to this directory with cd and type in npm install.
• for Linux, you can use the install script which would also automatically install node.js and ws.

Manual:

~$ git clone git://github.com/OgarProject/Ogar.git Ogar
~$ cd Ogar
~$ npm install
~$ node Ogar

Using the install script:

~$ sudo ogar-linux-script.sh install /your/preferred/directory
~$ sudo -u ogar -H /bin/sh -c "cd; /bin/node src/index.js"

Using sudo -u ogar -H /bin/sh -c "cd; /bin/node src/index.js" to launch the server increases security by running the process as an unprivileged, dedicated user with a limited shell and it is recommended to do so.

Currently, Ogar listens on the following addresses and ports:

• *:80 - for the master server
• *:443 - for the game server

Please note that on some systems, you may have to run the process as root or otherwise elevate your privileges to allow the process to listen on the needed ports. If you are getting an EADDRINUSE error, it means that the port required to run Ogar is being used. Usually, Skype is the culprit. To solve this, either close out skype, or change the serverPort value in gameserver.ini to a different port. You will have to change your connection ip to "127.0.0.1:PORT"

Once the game server is running, you can connect (locally) by typing agar.io/?ip=127.0.0.1:443 into your browser's address bar.

Configuring Ogar

Use "gameserver.ini" to modify Ogar's configurations field. Player bots are currently basic and for testing purposes. To use them, change "serverBots" to a value higher than zero in the configuration file. To add/remove bot names, edit the file named "botnames.txt" which is in the same folder as "gameserver.ini". Names should be separated by using the enter key.

Custom Game modes

Ogar has support for custom game modes. To switch between game modes, change the value of "serverGamemode" in the configurations file to the selected game mode id and restart the server. The current supported game modes are:

Console Commands

The current available console commands are listed here. Command names are not case sensitive, but player names are.

• Addbot [Number]
  • Adds [Number] of bots to the server. If an amount is not specified, 1 bot will be added.
• Board [String 1] [String 2] [String 3] ...
  • Replaces the text on the leaderboard with the string text.
• Boardreset
  • Resets the leaderboard to display the proper data for the current gamemode
• Change [Config setting] [Value]
  • Changes a config setting to a value. Ex. "change serverMaxConnections 32" will change the variable serverMaxConnections to 32. Note that some config values (Like serverGamemode) are parsed before the server starts so changing them mid game will have no effect.
• Clear
  • Clears the console output
• Color [Player ID] [Red] [Green] [Blue]
  • Replaces the color of the specified player with this color.
• Exit
  • Closes the server.
• Food [X position] [Y position] [Mass]
  • Spawns a food cell at those coordinates. If a mass value is not specified, then the server will default to "foodStartMass" in the config.
• Gamemode [Id]
  • Changes the gamemode of the server. Warning - This can cause problems.
• Help
  • Shows List Of Commands
• Kick [Player ID]
  • Kicks the specified player or bot from the server.

• Status
  • Shows the amount of players currently connected, time elapsed, memory usage (memory used/memory allocated), and the current gamemode.
• Tp [Player ID] [X position] [Y position]
  • Teleports the specified player to the specified coordinates.
• Virus [X position] [Y position] [Mass]
