Simple Custom Class getter/setter

Report · Jul 07, 2009

Hi,

I can I get this class to store the last frame number so I can use it in the next frame I go to?

package {

public class GlobalNumber {

        private var _theNumber:Number;

        public function GlobalNumber(num:Number) {
            _theNumber=num;
        }

        public function set theNumber(num:Number):void {
            _theNumber=num;
        }

        public function get theNumber() {
            return _theNumber;
        }

}

On frame 1

import GlobalNumber; // imports the class

var frameNumber:GlobalNumber = new GlobalNumber(1); // creates an instance of the class and sets the value = 1

trace(frameNumber) // 1 (playhead is arriving from frame 2 then I want it to =2 NOT =1)

On frame 2

frameNumber.theNumber = currentFrame;

// sets the class variable to 2

but when I mouseDown on a movieClip and send the playhead back to frame 1 the variable = 1 again

Is it because it's recreating the variable?

Should I delete the variable? If I do, how would I store the value?

The ultimate goal is to remember the last frame I was on.

thanks,

You could try making your getter and setter static:

package {

public class GlobalNumber {

private static var _theNumber:Number;

public static function set theNumber(num:Number):void {

_theNumber=num;

}

public static function get theNumber() {

return _theNumber;

}

Then on the timeline frame 1:

import GlobalNumber;

trace(GlobalNumber.theNumber) // NAN first run, then 2 on return

GlobalNumber.theNumber=1

trace(GlobalNumber.theNumber) //1

And on frame 2:

trace(GlobalNumber.theNumber) // 1

GlobalNumber.theNumber=currentFrame

trace(GlobalNumber.theNumber) // 2

gotoAndStop(1);
