Robotnik-Controls

This is an adaptive control library for nodebots. It's used by robotnik to listen for control events. Right now it only listens for events via IPC message, but the goal is that you'll be able to drop in a single library to provide the same control interface via:

• Console keyboard commands using keypress
• In-browser keyboard commands for Chromebots
• IPC commands sent via the native version of robotnik
• Plugged in video game controllers??
• LEAP motion??

Let's see where this goes.

Usage

button_demo.js

var button = require('robotnik-controls');
 
button.on('up', function() {
  console.log('Up was pressed');
});
 
button.off('up', function() {
  console.log('Up was released');
});

Supported buttons

There isn't really a definitive list, but currently robotnik uses:

up, down, left, right, red, green

Triggering events

var button = require('robotnik-controls');
 
button.off('up', function() {
  console.log('Up button was released.');
});
 
button.trigger('up', 'up'); // Prints 'Up button was released.'

Sending IPC commands

To send IPC control stats, you'll want to fork off a child and send it an object with button and state keys:

var childProcess = require("child_process");
 
var child = childProcess.fork('./button_demo.js');
 
// 'press' the up key
child.send({ button: 'up', state: 'down' });
 
// 'release' the up key
child.send({ button: 'up', state: 'up' });
