About scores on Facebook

yaxxar · September 2015

Hello my friends, in past days I published Nash n' Go on the Play Store, I will update the game in the next days, the game if you still don t play it, has two modes, normal and crazy, each mode has it s own score, and I want to post on facebook for a leader board of friends from the user, but I want to have a leaderboard per mode, like candy crush on its levels, the question is, how can I do that on gideros? Sorry for my bad english, thanks

Unfortunately facebook allows only one leaderboard per app.
You would need to use your own server (http://appcodingeasy.com/Mobile-Backend/Score-REST-API-on-PHP5-and-MySQL) or third party server to do that (like parse)

I use Parse Cloud Code and UrlLoader to send Rest request and provide several leaderboards for every level in some of my games.

Read this one before to understand Parse Cloud:

https://parse.com/docs/js/guide#cloud-code

You have to develop javascript functions in the server side for your game and expose them as Http REST API. Gideros provides UrlLoader to submit Http JSON request to those functions:

In the client side (Gideros) I define the following function to login to Parse with Facebook user:

-- Parse login using authData
function ParseAPI.login()
	local url = base_url.."/1/users"
	local method = UrlLoader.POST
 
	local data = {}
	local authData = {}
	local token = {
					id = social.userid,
					access_token = social.accessToken,
					expiration_date = social.expirationDate
					}
 
	authData.facebook = token
	data.authData = authData
	local body = json.encode(data)
 
	print("body", body)
 
	local loader = UrlLoader.new(url, method, headers, body)
 
	local function onComplete(event)
		print("onComplete", event.data)
	end
 
	local function onError()
		print("onError")
	end
 
	local function onProgress(event)
		print("onProgress: ")
	end
 
	loader:addEventListener(Event.COMPLETE, onComplete)
	loader:addEventListener(Event.ERROR, onError)
	loader:addEventListener(Event.PROGRESS, onProgress)
 
end

where social.userid, social.accesstoken and social.expirationDate are provided from previous Facebook user logged.

@jdbc thanks a lot I will check

This is the Parse REST API documentation:
https://parse.com/docs/rest/guide

With Gideros and UrlLoader, you can submit http request to this Rest API

Create persistent objects in parse.com is just use the following Lua functions:

require "json"
 
local base_url = '<a href="https://api.parse.com'" rel="nofollow">https://api.parse.com'</a>
local headers = {
					["X-Parse-Application-Id"] = "XXXXXXXXXXXX",
					["X-Parse-REST-API-Key"] = "XXXXXXXXXXXX",
					["Content-Type"]  = "application/json"
					}
 
-- Add session token to headers
local function addSessionToken()
	if (headers) then
		local sessionToken = dataSaver.loadValue("sessionToken") -- stored in Parse.login previously
 
		if (sessionToken) then
			headers["X-Parse-Session-Token"] = sessionToken
		end
	end
end
 
-- Create remote object of the given class name
function ParseAPI.createObject(className, object)
 
	print("ParseAPI.createObject", className)
 
	if (className and object) then
		local url = base_url.."/1/classes/"..className
		local method = UrlLoader.POST
 
		-- Session token added to headers
		addSessionToken()
 
		local body = json.encode(object)
 
		local loader = UrlLoader.new(url, method, headers, body)
 
		local function onComplete(event)
			print("createObject() onComplete", event.data)
 
			local response = json.decode(event.data)
			local objectId = response.objectId
			dataSaver.saveValue(className, objectId) -- store objectId on disk
 
		end
 
		local function onError()
			print("onError")
		end
 
		local function onProgress(event)
			print("onProgress: ")
		end
 
		loader:addEventListener(Event.COMPLETE, onComplete)
		loader:addEventListener(Event.ERROR, onError)
		loader:addEventListener(Event.PROGRESS, onProgress)
	else
		print("Error: class name or object is nil")
	end
end
