How integrate sharing via Facebook Messenger in Unity game. I have olready try to use Facebook Unity SDK 6.2.2 and 7.0.2 beta. Does Facebook SDK support it?
回答1:
This is not possible at the current time via the Unity SDK. Right now there is no support for the Messenger SDK as it is only available for Android and iOS.
In the current versions of the Facebook Unity SDK the only options you have for sharing/sending requests are the FB.Feed and FB.AppRequest methods.
