KordonBleu / jumpsuit

A sweet little webgame, which showcases and pioneers a few interesting new technologies!

JumpSuit

A sweet 2D canvas game. With your awesome suit, jump from planet to planet to conquer them!

It is the first game in which clients communicate with an authoritative server through WebRTC.

JumpSuit is distributed: anyone can create a game server. After registering (automatically) to the master server, your game server will be listed on jumpsuit.space for players, who will be able to play directly on it. For security reasons however, the assets and scripts are served by the master server.

Even more exciting: it's possible to create mods!

Supported environments

Currently, we only support Firefox and Chrome, because we use many recent additions to JavaScript. The server requires Node.js 6.0.0 or above.

How to build

$ npm install
$ node build/bundler.js

If you plan to host your own master server, don't forget to set the dev option.

How to run

Once the project is built, if you want to create a public game server, here is what you need to do:

$ node game_server_bundle.js

But if you are developing or running a LAN, you need to also make your own master server. Don't forget to set the dev option (see below). Yes, that means you have to set it in two different config files.

$ node master_server.js

Then you can access your master server at http://localhost in your browser.

Configuration

Game server configuration

The game server needs a configuration file. The default file is game_config.json, but it is also possible to choose which to use:

$ node game_server.js path/to/your/config.json

In any case, if it doesn't exists, it will be created.

You can modify settings without having to restart the server.

In this file you can set the following parameters:

Parameter	Explanation	Default	Variable type
dev	Enable debug messages	false	boolean
master	The master server your server registers to. If your host your own master server it should look like "ws://localhost:8080"	"wss://jumpsuit.space"	string
monitor	Displays a neat view of the lobbies in real-time	false	boolean
server_name	The name the master associates your server with	"JumpSuit server"	string

Master server configuration

The master server's configuration works the same way as the game server's, all parameters are saved in a file. Its default filename is master_server.json, but you can also choose another one:

$ node master_server.js path/to/your/config.json

In this file you can set the following parameters:

Parameter	Explanation	Default	Variable type
dev	Enable debug messages. Enable automatic reload of modified files (if you add a new file, you'll have to restart the server)	true	boolean
monitor	Displays a neat view of the connected game servers in real-time	false	boolean
port	Set the game server's port	80	integer

Build configuration

Parameter	Explanation	Default	Variable type
dev	Append a source map to the bundle	true	boolean
mod	Choose the server's gamemode	"capture"	string
