Excellent! Thanks for the hints! I was able to successfully create a custom event class and use it to control the main timeline. In this case the document class was my “controller” class.

Hi ‘worked’,

this.gotoAndPlay(2) isn’t going to effect the main timeline, as ‘this’ will be a reference to the clicked button within that scope (or possibly the black_box, depending on your code), you could this.parent…. your way up to the root, but that’s messy and easy to break.

What I’d do is dispatch an event from the iconClicked function, listen for that event in the control.as or whichever class is responsible for managing the root timeline, and call gotoAndPlay from there.

Quick question… but what if blackbox_mc has it’s own code, code that cause the timeline to gotoAndPlay another frame (from the main timeline) when clicked? For instance, if blackBox_mc created another button mc that listened for a click event, iconClicked(e:MouseEvent). How would i advance the main timeline to the 2nd frame when clicked?

function iconClicked(e:MouseEvent):void {
this.gotoAndPlay(2);
}

Thanks any help is appreciated!

I’m trying use a Class to control a bunch of movieclips I have created and instanced in Flash. I’ve already got the .swf working using only Flash, but I’m trying to learn how to write classes. (Reading past the added array stuff, which seems to be working in Flash) My references to, for example, topTextMischief_mc.visible = true is not working in the class. I get this error:

ReferenceError: Error #1069: Property topTextMischief_mc not found on ShowHide and there is no default value.
at ShowHide()
at testingarrayreplacement_fla::MainTimeline/displayRecipe()
at testingarrayreplacement_fla::MainTimeline/mischeifIn().

Here is the Class I have tried to create:

package
{
import flash.display.MovieClip;
public class ShowHide extends MovieClip
{
public var _buttonNumber:Number;
public var elementNames:Array = ["Mischief","SnapDragon","ShanghaiLemonDrop","AppleBlossom","GingerSnap","Yazitini"];
public var subElementNames:Array = ["topText","circleText","glass"];
private var graphicState:Boolean = false;

public function ShowHide(bNum:Number) {

_buttonNumber = bNum -1;

for (var i:Number = 0; i < 6; i++) {
if (i == _buttonNumber) {
graphicState = true;
}
else {
graphicState = false;
}
for (var j:Number = 0; j < 3; j++) {

this[subElementNames[j] + elementNames[i] +”_mc”].visible = graphicState;
// trace(subElementNames[j] + elementNames[i] + graphicState);
}

}

}
}
}

What could I do to get this working?

I’m afraid the answer to me should be “learn how Flash works, oh ignorant one.” Or “Try starting at the beginning, instead of diving into the deep end of Classes too early.”

This IS only my second Flash site… I have spent hours and hours trying to figure this out from books and the web, to no avail.

Here is the comp of the site I am working on:
