Lua webservice/http requests

[AggrorJorn]

Does anybody have good experience using a lua lib for calling webservices/making http requests? Currently looking at Luasockets but tinkering about whether this is even possible when you are making a game using the Leadwerks game player.

I've asked josh to give us a generic interface for this since he's in there doing it specifically for that API that allows us to track what players are doing. I doubt we will have that anytime soon, if at all though. He seems to be focusing on this specific API he's working with. Other than that anything that allows this via Lua would require an external non Lua library which means it's not going to work for the game player.

Thanks for confirming Rick. I was afraid that was the situation. Nothing that can be done on our part then. Here's hoping he exposes some of that functionality to a network class.

you can use luajit ffi, if you have to. http://www.leadwerks.com/werkspace/blog/120/entry-1182-luajit-awesome-luajit-enet-loaded/

 

the code there is super old, so just take it as inspiration because it's so bad.

This are some repos that deal with curl in lua.

These will not work in the sandbox and thus not in the game player.

 

As you probably know. You need to have the proper curl lib for the os installed in the same directory as the exe.

What do you want to use this for?

[AggrorJorn]

What I want to achieve is to call a rest api to either post, update or get data. Prefferably via JSON or XML.

 

For the winter games tournament I am making, I rely on level seeds. Highscores are currently saved to Steam highscores, but I can't store which popular seeds are being used by others. In general there is so much data that I want to store for usefull game mechanics and stats.

 

Something like this:

--Realy basic pseudo Get request 
var request = new Request() 
request.Url = "http://mysite.com/api/v1/popularseeds" 
request.Method = HttpMethod.Get 
var jsonResult = request.Execute() 

--Realy basic pseudo Post request 
var request = new Request() 
request.Url = "http://mysite.com/api/v1/popularseeds" 
request.Method = HttpMethod.Post 
var jsonString = "'user':'Aggror',
'attempts':'4',
'positions':{  
  '12345',
  '5674'
}" 
request.AddBody(jsonString) 
request.AddParameter("hmac",
"124362346") 
var jsonResult = request.Execute()

You could do this:

Analytics::SendGenericEvent("Level Seed",seed)

Thanks, I will give it go tonight.

[AggrorJorn]

So although using analytics is certainly cool and provides a lot of insights, we can not use it for querying inside the game.

[Josh]

gameanalytics.com does support querying data, but it is not in the Leadwerks API yet.

 

The most interesting application of this would be to construct a heatmap revealing player movements throughout your level.
