hx-googlecast-externs

Haxe/JavaScript externs for Google Cast Receiver, Sender, Game SDK.

Targeted at Cast version v1

---

Setup Chrome Sender application

📖 Tip: Make sure you read this first https://developers.google.com/cast/docs/chrome_sender

Include the cast_sender.js <script> tag

Add the script tag to your HTML page

<script type="text/javascript" src="https://www.gstatic.com/cv/js/sender/v1/cast_sender.js"></script> 

Initialization

Instead of using window['__onGCastApiAvailable'] = callback you can use ChromeCast.boot(callback).

To determine if the API is available and initialize it, you can provide the callback function before the Cast API loads. It is invoked with loaded == true when the API loads, or with errorInfo when load fails (e.g. when no extension is discovered).

ChromeCast.boot(function(loaded:Bool, errorInfo:String):Void
{
  trace('ChromeCast: version=${ChromeCast.VERSION}');
  trace('ChromeCast: loaded=$loaded, errorInfo=$errorInfo');
});

Requesting session

You initialize the API as follows:

var sessionRequest = new SessionRequest(appId);
var apiConfig = new ApiConfig(sessionRequest, sessionListener, receiverListener);
ChromeCast.initialize(apiConfig, onInitSuccess, onError);

From this point you are good to go and follow the docs.

---

Setup Custom Receiver application

📖 Tip: Make sure you read this first: https://developers.google.com/cast/docs/custom_receiver

Include the cast_receiver.js <script> tag

<script src="//www.gstatic.com/cast/sdk/libs/receiver/1.0.0/cast_receiver.js"></script>

Initialization

var castReceiver = CastReceiverManager.getInstance();
castReceiver.start();

From this point you are good to go and follow the docs.

---

Setup Game Manager API

📖 Tip: Make sure you read this first: https://developers.google.com/cast/docs/gaming

Follow this order of initialization:

1. Instantiate GameManager
2. Start Custom Receiver

var config = new GameManagerConfig();
config.maxPlayers = 5;
config.applicationName = "Haxe ChromeCast Application";

var gameManager = new GameManager(config);
gameManager.addEventListener(EventType.GAME_MESSAGE_RECEIVED, onGameMessage);

#if debug
// nice simple UI for debugging Cast Receiver.
var debugUI = new DebugUI(gameManager);
debugUI.open();
#end

var castReceiver = CastReceiverManager.getInstance();
castReceiver.start();

From this point you are good to go and follow the docs.

Implementation notes

• Package name The package of the Haxe externs are prefixed with chromecast instead of cast. This is to avoid conflicts with the cast-keyword in Haxe. As you can see in the extern classes, the @:native keyword rewrites this package to the expected package.

Updates

• I'm not sure if I will maintain the extern classes. It it provides as is. Feel free to do a pull-request.

Credits

• Part of the type definitions are created by Mark Knol. I'm not associated with Google. It could be the case stuff is missing, incomplete or even incorrect. I manually collected the Haxe extern classes and copy/pasted the documentation at it.
• Part of the definitions are created by renaudbardet, see https://github.com/renaudbardet/google-cast-receiver-hx-headers I've put it together for convinience.
