    problem with loading data from text file into an array????

    hi all,

    the code is about loading data from text file named:"data.txt"

    the data in the file are as following:
    &a1=1&
    &a2=2&
    &a3=3&
    &a4=4&

    now in the flash file:

    in the first frame on stage, code: loadVariables("data.txt", "_root");

    then in a button on stage, the code:
    on (press) {
    _global.arrayData = new Array();
    for (var i = 1; i<=4; i++) {
    var temp = eval("a"+i);
    arrayData[i] = temp;
    trace(arrayData[i]);
    }
    }



    in the trace panel, the result is:
    undefined
    undefined
    undefined
    undefined


    any help with that?

    Hi,

    How are you loading the text file?

    this might help you along, paste this into a new AS2 document and have the data.txt in the same directory

    PHP Code:
    var arrayData:Array = new Array();

    var 
    loadVars:LoadVars = new LoadVars();
    loadVars.load("data.txt");
    loadVars.onLoad = function(OK)
    {
        if (
    OK)
        {
            for (var 
    i:Number 1<= 4i++)
            {
                var 
    temp:Number this["a" i];
                
    arrayData.push(temp);
            }
            
    trace(arrayData);
        }
    }; 
    didnt see your other part, if you want to do it your original way,

    loadVariables("data.txt", "_root");

    PHP Code:
    on (press) {
        
    _global.arrayData = new Array();
        for (var 
    i:Number 1<= 4i++)
        {
            var 
    temp:Number _root["a" i];
            
    arrayData.push(temp);
        }
        
    trace(arrayData);

    and your altered original button code
    PHP Code:
    on (press) {
        
    _global.arrayData = new Array();
        for (var 
    1<= 4i++)
        {
            var 
    temp _root["a" i];
            
    arrayData[i] = temp;
            
    trace(arrayData[i]);
        }

    that lot should get you on

    thank you fruitbeard, for quick reply!

    the first code worked well, however, the 2nt and 3rd with the "press" event gave "undefined" result.

    regarding your Q: the data in the file is loading with "loadVariables" function if that what you mean.

            }
            
    trace(arrayData);
        }
    }; 
    this code was very helpful, thanks again!

    Hi,

    Glad you found something that worked for you out of that lot.
