xtralife include file and tutorial.

SinisterSoft · September 2017

Clan of the Cloud was changed to become xtralife some time ago.

It's an open source gaming back end.

http://xtralife.cloud/

xtralife gives you free cross platform leaderboards and achievements, plus loads of other stuff !

I originally wrote some functions to access clan of the cloud on any of the Gideros platforms using their REST interface.
Although still compatible, my old clan of the cloud routines were a bit clunky and so I've re-written them to be more streamlined.

Here they are:

local bs = {[0]='A','B','C','D','E','F','G','H','I','J','K','L','M','N','O','P','Q','R','S','T','U','V','W','X','Y','Z','a','b','c','d','e','f',
			'g','h','i','j','k','l','m','n','o','p','q','r','s','t','u','v','w','x','y','z','0','1','2','3','4','5','6','7','8','9','+','/',}
 
local function base64(s)
	local byte,rep=string.byte,string.rep
	local pad=2-((#s-1)%3)
	s=(s..rep('\0',pad)):gsub("...",function(cs)
		local a,b,c=byte(cs,1,3)
		return bs[a>>2]..bs[(a&3)<<4|b>>4]..bs[(b&15)<<2|c>>6]..bs[c&63]
   end)
   return s:sub(1,#s-pad)..rep('=',pad)
end
 
function xtralifeSave()
	if xtralife then
		local file=io.open("|D|xtralife.txt","w+")
		local saveString=json.encode(xtralife)
		if file then
			file:write(saveString)
			file:close()
		end
	end
end
 
function xtralifeSave()
	if xtralife then
		local file=io.open("|D|xtralife.txt","w+")
		local saveString=json.encode(xtralife)
		if file then
			file:write(saveString)
			file:close()
		end
	end
end
 
function xtralifeProfileEx(reply)
	if xtralife then
		if reply["displayName"] then xtralife.displayName=reply["displayName"] end
		if reply["lang"] then xtralife.language=reply["lang"] end
		if reply["firstName"] then xtralife.forename=reply["firstName"] end
		if reply["lastName"] then xtralife.surname=reply["lastName"] end
		if reply["addr1"] then xtralife.addr1=reply["addr1"] end
		if reply["addr2"] then xtralife.addr2=reply["addr2"] end
		if reply["addr3"] then xtralife.addr3=reply["addr3"] end
		if reply["avatar"] then xtralife.avatar=reply["avatar"] end
	end
end

You should copy these to a new lua file, eg xtralife.lua, add it to your project, right-click it in the project tree and exclude from execution.

It needs a plugin to be present: json. You can easily addit to your project using the new plugin system in the Gideros main project tree. If you are using anything other than the pre-built QT player then you may need to make a new player - eg for Android, iOS, etc...

Now in your main code, you enable 'json' first.

pcall(function() require "json" end)

Now you start xtralife:

require "xtralife"
xtralifeInit(" app key goes here "," app secret goes here ",true)  -- true for sandbox, else leave out.

You can find your app key and secret in the xtralife dashboard once you register and create an app there.

At some point you should call 'xtralifeResume()', this will login if the user has used xtralife in your game before, if not then it won't do anything. I usually call this on my main game front end loop - the start screen for example in the game.

Before you update any high scores or achievements - eg - as the gameover starts or level ends, then you should also call 'xtralifeLogin()' - this will create a new xtralife user if you haven't logged in before.

These two routine calls ensure that all goes smoothly on systems that don't already have a gaming lib - like html5, windows, etc...

If you are using the Gideros gaming plugin then you can use the gaming lib's 'getPlayerInfo()' to find the users id and alias name.

pt3...

Here is the code for the way I init the gaming lib:

pcall(function() require "gaming" end)
if Gaming then
	if android then
		if kindle then
			gaming=Gaming.new("gamecircle")
			gamingNetwork="kindle"
		else
			gaming=Gaming.new("googleplay")
			gamingNetwork="android"
		end
	elseif ios then
		gaming=Gaming.new("gamekit")
		gamingNetwork="gamecenter"
	end

After the login success event I call 'getPlayerInfo()' as mentioned above.

Here is my typical player_information_complete event code:

		gaming:addEventListener(Event.PLAYER_INFORMATION_COMPLETE,function(e)
			print("gaming PLAYER_INFORMATION_COMPLETE")
			if e.id then
				gamingName="Guest"
				if e.name then gamingName=e.name end
				if gamingNetwork=="android" or gamingNetwork=="kindle" then
					local n=gamingName:gsub('%W','')
					xtralifeLogin("email",(n.."<a href="https://forum.giderosmobile.com/profile/..e.id.." rel="nofollow">@..e.id..</a>."..gamingNetwork),"unknown")
				elseif gamingNetwork=="gamecenter" then
					xtralifeLogin(gamingNetwork,e.id)
				end
				print("network",gamingNetwork,e.id)
			end
		end)

This will attempt to login to xtralife, if xtralife has been used before then it will update the existing login with the alias and id codes for the network. Because we don't have the 'secret' for the gaming libs I have to re-use the 'email' tag on xtralife instead of the proper tags.

Now you are done!

All you need to do now is submit scores, grab the leaderboard, etc:

xtralifeScore(500,"test")   -- submit 500 to the 'test' leaderboard
 
xtralifeScores()  -- grab the main leaderboard, add "test" to grab the test leaderboard instead.

Enhancements:

Notice that people will be logged in as 'Guest'.

Add this to the beginning of xtralife.lua :

guestWord1={"Handy","Lost","Clever","Frozen","Alpha","Small","Tiny","Huge"}
guestWord2={"Box","Car","Circle","Triangle","Book","House","Horse","Cat","Dog"}

Now replace the xtralifeProfileEx(reply) with this:

function xtralifeProfileEx(reply)
	if xtralife then
		local update={}
		local doUpdate=false
		if reply["displayName"] then
			xtralife.displayName=reply["displayName"]
			if gamingName~="Guest" and xtralife.displayName~=gamingName then
				xtralife.displayName=gamingName
				update.displayName=gamingName
				xtralifeSetProfile({displayName=xtralife.displayName})
				doUpdate=true
			elseif xtralife.displayName=="Guest" then
				xtralife.displayName=guestWord1[math.random(#guestWord1)]..guestWord2[math.random(#guestWord2)]..math.random(10,99)
				update.displayName=xtralife.displayName
				doUpdate=true
			end
		end
		if reply["lang"] then xtralife.language=reply["lang"] end
		if reply["firstName"] then xtralife.forename=reply["firstName"] end
		if reply["lastName"] then xtralife.surname=reply["lastName"] end
		if reply["addr1"] then xtralife.addr1=reply["addr1"] end
		if reply["addr2"] then xtralife.addr2=reply["addr2"] end
		if reply["addr3"] then xtralife.addr3=reply["addr3"] end
		if reply["avatar"] then xtralife.avatar=reply["avatar"] end
		if doUpdate then xtralifeSetProfile(update) end
	end
end

That will generate a random name for the Guest and update the xtralife servers with the new information.

If you make these routines better then please add your new code to this thread so everyone benefits.

Quick question: if it uses REST api (UrlLoader), why does it require luasocket for ?

SinisterSoft · September 2017

Just mime for b64. Is it in another Gideros 'built-in' lib - if so then I could use them and get rid of socket.

see function xtralifeHeader()

SinisterSoft · September 2017

btw, I tried something like this before:

local bs = { [0] =
   'A','B','C','D','E','F','G','H','I','J','K','L','M','N','O','P',
   'Q','R','S','T','U','V','W','X','Y','Z','a','b','c','d','e','f',
   'g','h','i','j','k','l','m','n','o','p','q','r','s','t','u','v',
   'w','x','y','z','0','1','2','3','4','5','6','7','8','9','+','/',
}
 
local function base64(s)
   local byte, rep = string.byte, string.rep
   local pad = 2 - ((#s-1) % 3)
   s = (s..rep('\0', pad)):gsub("...", function(cs)
      local a, b, c = byte(cs, 1, 3)
      return bs[a>>2] .. bs[(a&3)<<4|b>>4] .. bs[(b&15)<<2|c>>6] .. bs[c&63]
   end)
   return s:sub(1, #s-pad) .. rep('=', pad)
end

but it didn't work because I think null is expected at the end.

	print(mime.b64(xtralife.id..":"..xtralife.secret))
	print(base64(xtralife.id..":"..xtralife.secret))

outputs:

NTliYWVhOWFiNTFkZGNhOTA1ZmNiY2U0Ojg2OWM2NzE5MjliOGVhY2NmNGM0ZDgyNDM0YTllMjIwNDc2NjM0YWE=	nil
NTliYWVhOWFiNTFkZGNhOTA1ZmNiY2U0Ojg2OWM2NzE5MjliOGVhY2NmNGM0ZDgyNDM0YTllMjIwNDc2NjM0YWE=

I tried adding .."\0" but that doesn't work - it doesn't add the null.

SinisterSoft · September 2017

Updated code/tutorial to not use sockets lib and instead use a base64 function.

snooks · September 2017

Thanks very much for sharing this, it looks like an interesting cross platform solution I'd never heard of before. I think this deserves to be in a repo somewhere.

HubertRonald · September 2017

Quick question: if it uses REST api (UrlLoader), why does it require luasocket for ?

and also @SinisterSoft doesn't use LuaSec

function xtralifeCall(call)
	return "<a href="https://&quot;..xtralife.name.."-api0"..xtralife.server..".clanofthecloud.mobi/"..call" rel="nofollow">https://&quot;..xtralife.name.."-api0"..xtralife.server..".clanofthecloud.mobi/"..call</a>
end

How is it possible? tell our your magic.

SinisterSoft · September 2017

@HubertRonald Https support is built-in to the various Gideros players.

For windows however you have to include a couple of extra files:

I'll try and get someone xtralife to join the forum and post about some of the features of the system here. It's *really* good.

MikeOfTheClan · September 2017

Hello, I'm Michael, founder of Clan of the Cloud, which became XtraLife last year.

Anthony has pretty much said everything (many thanks to him), but just wanted to add that we offer a hosted solution (which means you just need Anthony's SDK and you're good to go), or you can use our Open Source solution. In this case, you install everything on your own servers and you manage it the way you like it!

Other than that, we provide mostly all the features you'd expect from a backend, including player management (with support for social networks or private user base), leaderboards, achievements, turn by turn multiplayer, virtual currencies, cloud synchronization, sending of data between users, referral system, server side code, and much more.
Also, we do provide many "low level" features with which you can implement pretty much all your needs. Do you need a very custom clan feature? Check. Challenges based on virtual currencies betting? Check

Do not hesitate to contact us (or me) if you need more info. We like to talk about your needs on Slack!

SinisterSoft · October 2017

I've updated my files a little re xtralife. Here are the latest versions:
https://www.dropbox.com/s/4vrput6ytgvsqas/xtralife.lua?dl=0

It down downloads the avatar of the person if xtralife have it, it shows how to manipulate the image before saving.

It's all a bit of a hack so use it as the basis for your own mods. I'm updating soon because of work done by @MikeOfTheClan for extra googleplay and gamecircle support. So expect changes!

On my main game front end I call xtralifeResume()

This will login to xtralife if previously logged in.

At the end of the game I check if xtralife is logged in, if not then I try the xtralifeLogin() so it makes up a username/password. That way, in the future, if no facebook, google place, gamecircle or gamecentre then it will still record and compare leaderboards, etc...
