HappyFunTimes is a system for playing party games that are meant to be played with a bunch of people in the same room and 1 ideally large display.
HappyFunTimes is abbreviated with HFT in this documentation.
HFT is a library you add to your game that runs a small webserver. There are currenty 3 forms of this library. A Unity version, An Electron version and a stand alone server version.
Users connect to this server with their smartphone and it serves them a webpage you create that presents a controller for your game. The game and the controllers then talk over WebSockets through the server. Note that the smartphones must be on the same WiFi as the computer.
There is a rendezvous server
that helps users easily connect to your game. Users go to happyfuntimes.net
on their phones and it will redirect them back to your game's server
(for example http://192.168.1.123:18769)
HFT also supports running without the internet for use in installations. To do this it supplies its own DNS server so that when the user connects their phone to your WiFi all websites will lead to your game. It even includes support for iOS devices captive portal detector so that when an iOS user connects to your WiFi they'll automatically join the game without typing anything.
HFT supports a synchronized clock across all devices. This can be used to coordinate multiple machines.
HFT also supports passing players between mutliple machines running games. As an example see this game that runs across 7 machines.
