Hello,

Problem description:

• Player should be able to play the game without logging into the facebook to authenticate himself.
  
• I have a leaderboard and I'm posting score at the end of a level, only for user logged into facebook.
  
• At the end of a level, in case of player being logged off I want to show him how many points he got and which rank he would get if he would be logged in.

I have a feeling that I'm missing something obvious here. I know that I can authenticate player device without connecting it to FB account to let him play the game and be able to display leaderboard. But can I simulate posting his score at the end of a level to get his rank? I don't want to save this score in the leaderboard if he don't log in into facebook.

I have thought about two workarounds but both of them seems to be wrong:

1. Post score as a "device", get his rank and then ask to log in. If he logs in - save the score under his newly connected FB account. If player decides to not log into the FB - delete the "device score".
2. Request all leaderboard entries (ugh!) and find manually (ugh again!) what is the possible rank of my player.

Is there a out-of-the-box solution for this kind of scenario that I'm missing?

Additional info:

I'm using Unity and creating builds for WebGL, iOS and Android.

var myScore = Spark.getData().simEScore; //That's score passed with the event
//We're using score passed in event to determine rank. "easyLead" is shortCode for my leaderboard
var rank = Spark.getLeaderboards().getLeaderboard("easyLead").getRankForScore({"score" : myScore}); 
Spark.setScriptData("rank", rank) //Rank is returned

Turned out there is a nearly out-of-the-box solution for that. I have missed a getRankForScore method in CloudCode. So if anyone ever need answer for above question here it is:
1. Check out how to use CloudCode here: https://docs.gamesparks.net/developer-portal/cloud-code/using-cloud-code
2. Set up an event with one NUMBER attribute, that will be the score you want to pass to getRankForScore
3. Edit CloudCode for that event (check #1 for How To Do).
Here's code that I have used:

var myScore = Spark.getData().simEScore; //That's score passed with the event
//We're using score passed in event to determine rank. "easyLead" is shortCode for my leaderboard
var rank = Spark.getLeaderboards().getLeaderboard("easyLead").getRankForScore({"score" : myScore}); 
Spark.setScriptData("rank", rank) //Rank is returned

 4. It's done, remember to update your custom GameSpark SDK in Unity.
