XML & array problem

[[email protected]]

Hello,

I'm trying to load XML data in an array (it is not finished yet because I need some help)... This will create levels for a breakout game, where 1 creates a block and 0 doesn't. I need to write an XML file storing the levels and the array content for the blocks. In the end I should be able to fill up an array like below using the extracted information!

var lvl:Array =     [[0,0,0,1,0,0,0],
                   [0,0,0,0,0,0,0]];

I have been trying so hard to get this done but can't find the correct solution so I was wondering if someone could give me a hint on how I should write the XML and actionscript to load the numbers into the array (note that I'll need an array in another array).

Thank you for your help!

so what you want to do is store an array in xml?

<myxml>
<thearray>[[0,0,0...],[..]]</thearray>
</myxml>

//load the xml via a urlloader
//add a complete event listener 
function completeHandler(e:Event):void
{
  var thexml:XML = XML(e.target.data);
  theArray:Array = Array(thexml.thearray);//try that
  //you can also bring it in as a string then chop it up into an array 
  //based on "[", "]", and commas

}

It works, thank you! I was using the same methods but much more complicated... The only thing with this method is that the end-user won't immediately know how to insert or remove blocks but no prob, I'm glad it works! Thx again for the quick reply!

Hmmm, when trying to fill the array with the xml for level 2 I get an error because I'm using the same var 2 times. When there are no blocks left on the stage to hit I just tell the currentLvl to add 1 using ++, this works. Then I call the function to create the level but now level 2 us ing the code below.

if (currentLvl == 1) {
        var lvlArray:Array = new Array (thexml.lvl1array);
    }
    if (currentLvl == 2) {
        var lvlArray:Array = new Array (thexml.lvl2array);
    }

What am I doing wrong?

Regards.

Whatever you are trying to do (of which I'm not really sure...)
- don't declare variables inside loops or inside conditions.
- don't use Array's constructor - it is virtually unexisting function. Use Array literal - you won't get confused at least when trying to convert something to array or put an array inside another array.

EDIT: Ah, it seems like you ware trying to create an array from string - then look into Array#split([delimiter:String]); method e.g.:

var array:Array = "a,b,c".split(",");

i'm not sure what your trying to do, but :

var lvlArray:Array;
if (currentLvl == 1) {  lvlArray = new Array (thexml.lvl1array);   }    
 if (currentLvl == 2) {  lvlArray = new Array (thexml.lvl2array);   }

is how that should be (don't mind the formating) "var lvlArray:Array" should only happen once, strictly speaking.

You could also just keep the XML elements the same (instead of naming them differently: lvl1array, lvl2array, etc)...

So your XML would be like this:

<myxml>
<thearray>[[0,0,0...],[..]]</thearray>
<thearray>[[0,1,0...],[..]]</thearray>
<thearray>[[1,0,1...],[..]]</thearray>
</myxml>

And you could just reference each "level" as a separate element in your XML Array... So level 1 would be lvlArray[0], level 2 would be lvlArray[1], etc...

I can't seem to be able to use this code in the code I already wrote... Is there anyone who would like to take a look at this code to help me? I'd really appreciate it and for someone who knows a lot about flash this should be easy...

Kind regards!
