LeapJS
======

LeapJS is a Javascript library that provides the functionality and object structure of the Leap API to assist developers who are working with the Leap Motion in a browser environment.

## Including

Include Leap.js for debugging and access to "private" variables:
```html
<script src="Leap.js"></script>
```

Include Leap.min.js for deployed applications to reduce load times:
```html
<script src="Leap.min.js"></script>
```

## Tutorial

```javascript
// Create a controller to connect to the Leap Motion
myController = new Leap.Controller("ws://localhost:6437/");

// Create a listener
myListener = new Leap.Listener();

// Listener.onFrame is called each time a frame is received
myListener.onFrame = function(controller){

var frame = controller.frame();
    var hands = frame.hands();
    var pointables = frame.pointables();
    
    var gestures = frame.gestures();
    
    // Awesome code goes here
}

// Add the listener to the controller
myController.addListener(myListener);

// Enable the screenTap gesture
myController.enableGesture("screenTap", true);

// Listener.onConnect is called when the connection is open
myListener.onConnect = function(controller){
 
    // Calibrate the screen
    calibrate = new Leap.Calibrate(controller);
    calibrate.onComplete = function(screen){
        // Save the screen
        // Or access it later with myController.calibratedScreens()[0]
    }
}
```
