Using it

Setup a Facebook App

To be able to log in Clan of the Cloud with the user's facebook account, you need to create a Facebook App

On Facebook Developer website, check the following settings :

Facebook Settings

Download the Facebook SDK for Unity

Download the facebook SDK for Unity here and import the package into your project.

Configure your AppID through the Facebook Settings menu in Unity. Do not forget this step as facebook will throw an error upon usage otherwise.

Fix platform specific issues

When compiling for iOS, you may have to tweak some settings if the resulting project fails to compile with an error related to an autorelease call or something like ‘no known class method for selector 'publishInstall:withHandler:’orError: ARC forbids explicit message send of 'autorelease'. Open your project properties (select your project at the root of the project tree), go to the *Build Phases* tab, and under *Compile Sources*, double click on FbUnityInterface.mm and type in-fno-objc-arc` to disable ARC for facebook. This step may not be required anymore at the time you are reading this though, so just try without it first.

When compiling for Android, you may get an error saying java.lang.IllegalArgumentException: already added: Landroid/support/v4/accessibilityservice/AccessibilityServiceInfoCompat;. This is caused by a conflict between the CotC SDK and the facebook plugins, which use a different build system although they reference the same library. In this case, you need to remove the Assets/Plugins/Android/facebook/libs/android-support-v4.jar and associated meta files.

Using the Facebook integration plugin

Import the facebook integration package and place the CotC Facebook Integration prefab on your scene (under Cotc.FacebookIntegration/Prefabs). Through this object, you will be able to access the CotcSdk.FacebookIntegration.CotcFacebookIntegration API. Use FindObjectOfType as described in getting started.

var fb = FindObjectOfType<CotcFacebookIntegration>();

fb.LoginWithFacebook(Cloud).Done(gamerResult => { ... });
