- Declaration
static void AuthenticateAsGuest(const FString& Server, const FString& UserName, CavrnusAuthRecv OnSuccess, CavrnusError OnFailure);
Delegates Options:
typedef TFunction<void(const FCavrnusAuthentication&)> CavrnusAuthRecv;
typedef TFunction<void(const FString&)> CavrnusError;
DECLARE_DYNAMIC_DELEGATE_OneParam(FCavrnusAuthRecv, FCavrnusAuthentication, Auth);
DECLARE_DYNAMIC_DELEGATE_OneParam(FCavrnusError, FString, Error);
- Description
Creates a guest user account with a given name and joins as that user.
This is a good way of immediately getting your customers into a space without requiring any inputs from them.
Keep in mind that Guest accounts have limited permissions, which can be customized in the Management Console.
OnFailure generally shouldn’t trigger outside of rare cases.
OnSuccess provides a FCavrnusAuthentication which you can then store/load on your local machine to use on a future run without requiring the user to re-login.
