classes and variable. Why are they so sensitive??

[luciferonline]

package classes
{
public class xml_data_loader /*extends XMLListCollection*/
{


public static function call_XML() :void{

public var gauge_3_2:Number = 12;

}

}

}

Can some one explain why I can not access these vars from a seperate .as file.


this is what I am getting:


1114: The public attribute can only be used inside a package.


Cant seem to get a grip on it.
cheers

Try:

package classes
{
public class xml_data_loader /*extends XMLListCollection*/
{
public var gauge_3_2:Number = 12;

public static function call_XML() :void
{}
}
}

no still is bugging out.
What it is for is to set about 20 variable and then assign them to a switch statement:
like so:


public function guageLoaded(which:Number):void{
trace(which);

var thisGuage:MovieClip;

switch(which){

case 1:
thisGuage = guage_1.content as MovieClip;
thisGuage.positionNeedles(gauge_1_1, gauge_1_2, gauge_1_3, null, 0.2);
break;


the only problem is the switch statement is out of the scope of the xml loader(that you helped me with the other day).

I just want to make the vars global?

Its seems weird that you cant just pull values as you please. or am I just a retard??

BUMP^^^^ Anyone??

What flexy told you was correct. public vars are declared inside a class, not a function. You would use the function to assign data to the public vars. Like this:


package classes
{
public class xml_data_loader /*extends XMLListCollection*/
{
public var gauge_3_2:Number;

public static function call_XML() :void {
gauge_3_2 = 3;
}
}
}


So when you're XML loader function is complete, assign the XML data to public class vars. If it is "bugging out" as you say, you should post more code so we can tell you what you're doing wrong.

hey cheers fellas.
Its a little more complex than that. I am trying to assign xml data to the vars

: gauge_1_1 = Math.floor(((Number(myXML.gauges.data[0].current))-(Number(myXML.gauges.data[0].target)))/(Number(myXML.gauges.data[0].target))*100);

The vars exist inside:
function xmlLoader(evtObj:Event) :void
{}

its killin me.

If you are interested this is the entire class package:

public class xml_data_loader //extends ArrayCollection

var myXMLURL:URLRequest = new URLRequest(XML_URL);
var myLoader:URLLoader = new URLLoader();
myLoader.addEventListener( Event.COMPLETE, xmlLoader );

}

the first var is red lighting now. Saying undefined variable.

[flexy]

I'm going to chip in and say that you can't reference gauge_1_1 from within your static function call_XML(). You'll need to make it static.

Also, looking at the positioning of your closing braces, you're nesting methods.

[luciferonline]

I found that the xml loader wont work unless it is nested.
are you referring to the function being static or the vars?
cheers

So now I have two classes.
They seem to be fine(touch wood)
The only thing is xternal.as is saying

1017: The definition of base class Sprite was not found.
any thoughts?
