ActionScript 3.0: how to use SharedObject

with 4 comments

I’ve been using SharedObject a lot lately, Flash’s own version of a cookie.
and so I thought it’d be about time telling a bit about how this works.
so I’ve made this very simple example, that works as a counter, telling you how many time you’ve visited a certain webpage.
check out the simple counter built with SharedObject here:

reload the page, to see how the SharedObject tells you how many times you’ve reloaded it.
the motor behind this is kinda simple.
here’s all the actionscript:

//create a shared object or load it
var sharedObject:SharedObject = SharedObject.getLocal("firstTimeOrNot");
//if the sharedObject is only just created, the min_variabel will be equal undefined and we set it to 0
//if it exists we just add 1 to it, as loading it counts as another visit to the webpage
if (sharedObject.data.min_variabel == undefined){
   sharedObject.data.min_variabel = 0;
   sharedObject.flush();
} else {
   sharedObject.data.min_variabel++;
   sharedObject.flush();
}
//the .flush() makes sure, that the changes of the min_variabel is immediately saved to the sharedObject
//set the dynamic text equal to the min_variabel
numberOfVisits.text = sharedObject.data.min_variabel

questions?
just post them below

1. Hi, I’ve been trying to get shared objects to work for a long time. I just found this and tried copy-pasting your code in a flash file and it worked. I also tried to find what I have done wrong, and kinda failed…

   Could you help me? Here’s my code:

   var sharedObject:SharedObject = SharedObject.getLocal(“ftd”);
   if (sharedObject.data.played != undefined) {
   _quality = sharedObject.data.setQUALITY;
   hud = sharedObject.data.setHUD;
   helpers = sharedObject.data.setHELP;
   } else {
   _quality = “low”;
   //Init save vars…
   _root.loadingInfo.replaceText(0,1000,”LOADING: CREATING GAME”);
   sharedObject.data.played = new Boolean(true);
   sharedObject.data.setQUALITY = new String(_quality);
   sharedObject.data.setHUD = new Boolean(hud);
   sharedObject.data.setHELP = new Boolean(helpers);
   error = sharedObject.data.played == false;
   if (sharedObject.data.played != true) {
   _root.loadingInfo.replaceText(0,1000,”ERROR: CANNOT USE SHAREDOBJECTS – CANNOT PLAY”);
   }
   if (sharedObject.flush() != true) {
   _root.loadingInfo.replaceText(0,1000,”ERROR: WILL NOT SAVE – CANNOT PLAY”);
   error = true;
   lbar.stop();
   }
   }

   Thank you!

2. Oh, I think I found my mistake. Please tell me if I’m wrong (but it works now! *happy*); When setting variables in sharedObject.data you cannot call the new method. You have to just put the value, i.e.
   sharedObject.data.X = 3;
   instead of
   sharedObject.data.X = new Number(3);

   Thanks again!
