UniWeb Actions
« on: November 24, 2012, 03:00:19 PM »
The playmaker's WWWobject is pretty limited.
EG: doesnt work for REST, setting header, JSON decode.
Hopefully UniWeb can be used for improvement.

hi,

 Yes, UniWeb is the only viable solution for proper webService Access for any serious projects. wwwObject will get the job done for simple things and proof of concepts tho.

Json should be handled by newtonSoft great library.

Like Data management, web services and online access in general is such a vast topic that it is difficult to find the right balance, maybe you could list some usage you would like to benefit like obviously texture downloading, but you might other needs.

It would be indeed very good to develop a series of custom actions to support UniWeb conveniently within PlayMaker. maybe you could participate if you have some scripting knowledge? This would be welcome indeed.


bye,

 Jean

Ya. newtonSoft has a great JSON library.
But UniWeb comes with its JSON Decode and Econde native support, so I will just take that instead.

UniWeb has great features like
- HTTPS
- JSON,
- cookies,
- texture downloading,
- websocket,
- steam,
- keepAlive,
- HTTP cache,
- GZIP,
- send binary data(eg: after you take a picture in iphone and you can send it to server to save it)
...etc .. just like all the stuff you would expected for networking.

Playmaker cant really do serious network game with only get request and socket.

Sure. I wrote my own script just now. It works for basic REST server calls.
Altho I am not sure if i am doing it right without yield.
Hopefully someone can add more functions.

         Fsm.Event(isError);
         return;
      }
      progress.Value = r.Progress;
      if(r.state != HTTP.RequestState.Waiting) { //there might be some chunks available
         
      }
      if (r.isDone) {
         storeText.Value = r.response.Text;
         /*
         var tex = new Texture2D (512, 512);
         storeTexture.LoadImage (r.response.Bytes);
         renderer.material.SetTexture ("_MainTex", tex);
         storeTexture.Value = tex;
         */
         Fsm.Event(string.IsNullOrEmpty(errorString.Value) ? isDone : isError);
         Finish ();
      }

      
   }

Hi,

 Good! thanks for that.

--  I noticed that your "storeTexture" will not work because the related code is commented out. So maybe you should comment also the public variable, else users will think it's a bug.


Also, don't hesitate to share the actual file in the "Share new action" section of the forum, it will be easier for people to find your work.
