I could use some help figuring out how to convert some older script to AS 3. I’ll start simple - here is the main class and a bit of code on the main timeline that calls it. I’m not certain how to declare the “settings” variable in AS 3 style. And I’m not sure how to call the “QuickCheck” public function from the main timeline.

```auto

package {

    import flash.display.*;
    import flash.events.*;
    import flash.net.*;
    import flash.display.Stage;
    import flash.display.StageAlign;
    import flash.display.StageScaleMode;
    import flash.display.StageDisplayState;
    import flash.accessibility.AccessibilityProperties;
    import flash.text.TextField;
    import flash.text.TextLineMetrics;
    import flash.text.AntiAliasType;
    import flash.text.TextFormat;
    //----------------------------------------------------------------
    import flash.media.Sound;
    import flash.media.SoundLoaderContext;
    import flash.media.SoundChannel;
    //----------------------------------------------------------------

    public class QuickCheck extends MovieClip {

        //CUSTOMIZE//////////////////////////////////////////////////////////
        var settings = new Object();
        //correct color
        settings.correctColor = "#85BB3D";
        //incorrect color
        settings.incorrectColor = "#CF7E05";
        //weather feedback is shown or not
        settings.hasFeedback = true;
        //prefix for the answer choices
        settings.choiceLetter = "A,B,C,D,E,F,G,H,I,J";
        //space between the questions and answer chocies
        settings.questionChoiceBuffer = 14;
        //space between the answer choices
        settings.choiceBuffer = 14;
        //CONSTRUCTOR FUNCTION///////////////////////////////////////////////
        public function QuickCheck(path, questionArr, directionsArr):void {
            //reference to path
            this.path = path;
            this.questionArr = questionArr;
            this.directionsArr = directionsArr;
            this.currentQues = 0;
            this.totalQues = questionArr.length;
            this.currentAnswer;
            this.submitOpen = false;
            //trace("CONSTRUCTOR FUNCTION EXECUTED ****************************");
        }
        /////////////////////////////////////////////////////////////////////
        private function init(settings):void {
            this.correctColor = settings.correctColor;
            this.incorrectColor = settings.incorrectColor;
            this.hasFeedback = settings.hasFeedback;
            this.choiceLetter = settings.choiceLetter.split(",");
            this.questionChoiceBuffer = settings.questionChoiceBuffer;
            this.choiceBuffer = settings.choiceBuffer;
            //trace("init() called");
        }
}

///////////////

On Frame 18 of the main timeline (this is AS1.0/2.0 style script):

var activity = new QuickCheck(this, questionArr, directionsArr);
activity.init(settings);

```
