New Features

[#1031] Roar now supports the Facebook Offer Wall

To integrate the Facebook in-app currency offer wall into your application you must follow these steps:

From the Facebook configuration UI: et the currency that you wish to use; and set the Facebook credits callback to api.roar.io/gamename/admin/fb/ (using the correct game name and server for your game).
Serve a currency icon and a currency info file from one of your servers. The content of the info file should look like this:

<html>
 <head prefix="og: http://ogp.me/ns#
    fb: http://ogp.me/ns/fb#
    fbpayment:http://ogp.me/ns/fb/fbpayment#">
   <meta property="fb:app_id"      content="[YOUR APP ID]" >
   <meta property="og:type"        content="fbpayment:currency" >
   <meta property="og:url"         content="[URL OF THIS FILE]" >
   <meta property="og:title"       content="[NAME OF YOUR CURRENCY]" >
   <meta property="og:description" content="[DESCRIPTION OF THIS CURRENCY]" >
   <meta property="og:image"       content="[URL TO AN IMAGE]" >
   <meta property="fbpayment:rate" content="[CONVERSION RATE OF FB INTO YOUR CURRENCY]" >
 </head>
</html>

Display the offerwall from your app, like this: (this example uses jQuery)

$('#YOUR_BUTTON').click( function(){  var obj = {    method: 'pay',    action: 'earn_currency',    product: '[URL OF CURRENCY INFO PAGE]'  };  FB.ui(obj, function(data) { /* handle response */ } );});

Bug Fixes

[#1087,1086] Saving old games configuration no longer generates a warning/error

Some old games that had not been updated were generating an error or warning when saving their configuration. In most cases the configuration was getting saved correctly, so this was mostly a cosmetic issue.

[1084,1083] Improved Facebook credits handling

The Facebook credits handling code relied on some Facebook features that were soon to be deprecated. The handling code has been updated to behave in compliance with the latest Facebook API.
