Just wanted to let you know the Ludei have fixed the Game Center feature and plan to add Facebook in the following weeks.
They have also added the following functionality to their services.
Cocoon.Camera: It represents the CocoonJS camera plugin API.
Cocoon.Device: All functions related to the device.
Cocoon.Dialog: Dialog functions (prompt / confirm).
Cocoon.Motion: All functions related to the Accelerometer and Gyroscope.
Cocoon.Proxify: It proxies different functions of the WebView environment, like Audio objects and XHR.
Cocoon.Touch: It holds some functions to handle the touch events in both surfaces (Cocoon & WebView).
Cocoon.Widget: It holds the WebDialog widget, which essentially shows a Webview on top of the CocoonJS layer.
Cocoon.Utils: It holds some different utilities.
Additionally, note that Construct 2 plugin will be updated in order to use these new plugins.
I'm not advocating for them. Just keeping you informed.
