MultiOgar

Ogar game server with fast and smooth vanilla physics and multi-protocol support.

Current version: 1.2.47

Project Info

MultiOgar code based on Ogar code that I heavily modified, and will continue to update. Almost all physics and protocol code were rewritten and optimized. The OgarProject owns Ogar, and I do not claim it as mine! Original Ogar found here

The goal is to make good and smooth physics and cleanup the code.

Screenshot

MultiOgar console:

Version 1.2.8:

• 1000 bots, 500 viruses, 1000 foods, map 14142x14142
• Works very-very smooth (with a little slower speed, but it will not be noticed by user).
• CPU load: 14% (x4 core)
• Memory usage: 70 MB

Install

Windows:

• Download and install node.js: https://nodejs.org/en/download/ (64-bit recommended)
• Download MultiOgar code: https://github.com/Barbosik/MultiOgar/archive/master.zip
• Unzip MultiOgar code into some folder
• Start command line and execute from MultiOgar folder

npm install

and run the server:

cd src
node index.js

Linux:

# First update your packages:
sudo apt-get update

# Install git:
sudo apt-get install git

# Install node.js:
sudo apt-get install nodejs-legacy npm

# Clone MultiOgar:
git clone git://github.com/Barbosik/MultiOgar.git

# Install dependencies:
cd MultiOgar
npm install

# Run the server:
cd src
sudo node index.js

Clients

This lists Ogar clients and server trackers that I found on internet.

###Ogar server trackers

URL	Description
http://ogar.mivabe.nl/master	MivaBe, tracks a lot of servers
http://c0nsume.me/tracker.php	c0nsume.me server tracker

Now you can allow MultiOgar to be listed on a server tracker. Just set serverTracker = 1 in the gameserver.ini, and your server will appear on these pages: http://ogar.mivabe.nl/master , http://c0nsume.me/tracker.php If you don't want to include your server to tracker list, just set serverTracker = 0 and the server will not ping the server tracker.

###Ogar clients Just replace 127.0.0.1:443 in the url to the server IP and port to play.

URL	Protocol	Description
http://agar.io/?ip=127.0.0.1:443	8	Vanilla
http://ogar.mivabe.nl/?ip=127.0.0.1:443	early 5	MivaBe, pretty smooth, custom graphics (anime)
http://play.ogarul.tk/?ip=127.0.0.1:443	4	OgarUL, vanilla style
http://c0nsume.me/private4.php?ip=127.0.0.1:443	5	vanilla style

What's new:

• 1.2.47: Improved stability and performance; added mute/unmute command
• Added support for secure websocket connections (TLS)
• Fixed mass decay
• Added ejectSizeLoss
• Added sub-net ban feature (use ban xx.xx.xx.* or ban xx.xx.*.* to ban entire sub-network)
• Added performance optimizations, now up to 700 bots with no lags at all
• Fixed bug when some cell split/eject were shown with delay for some clients
• Added a lot of protocol optimizations, now server works with no lags at all even with 64 connected players
• Added server version, now you can check if your MultiOgar code is fresh
• Significant performance improvement and more smooth physics
• Added protocol optimizations to reduce lags on cell multi split
• Fixed pop-split behavior
• Added spectate walk through feature (use Space key in spectate mode to lock the current player or to lock the next one. Use key Q to reset into the normal mode. Locked player is highlighted on leaderboard)
• Fixed cell-split order, now split-run works ok
• A little performance improvement for split/eject
• Fixed min mass to split/eject
• Fixed mass-limit behavior
• Added chat player commands /skin and /kill (to change skin, just type /skin %shark in the chat)
• Added scramble level 3 (anti-bot/anti-minimap protection), unsupported on some clients (unfortunately include vanilla, ogar.mivabe.nl works ok)
• NOTE: there is major gameserver.ini change, previous version is incompatible!
• Massive perfromance improvement & reduce network traffic
• Split behavior - fixed;
• Protocol code - optimized;
• Massive performance improvement with quad-tree lookup;
• Split/Eject - physics code rewritten;
• Player speed - physics code rewritten;
• Cell remerge - physics code rewritten;
• Cell collision - physics code rewritten;
• View area - code rewritten;
• Spectate - code rewritten;
• Mouse control and cell movements - physics code rewritten;
• Border calculations - rewritten;
• Border bouncy physics - fixed and improved;
• mainLoop - cleaned;
• Added support for different protocols (4, early 5, late 5, 6, 7, 8);
• Added automatic mouse message type recognition;
• Added chat support;
• Added anti-spam protection;
• Added skin support (use name "< shark > Fish", remove space);
• Color generator replaced with hsv model;
• Memory leaks - fixed;
• Performance improved and optimized
• Added support for server tracker ogar.mivabe.nl/master

Most of the physics code from the original Ogar were rewritten. The physics engine in MultiOgar is pretty close to the old vanilla physics.
