How to load this into a Main class in AS3? - actionscript-3

I'm learning some AS3 basics and would like to set up a native menu up the top of the window.
I found this menu example at Adobe: https://help.adobe.com/en_US/as3/dev/WS5b3ccc516d4fbf351e63e3d118666ade46-7de7.html
How would I add this to my Main class so that the menu appears please?
The MenuExample class is in the same dir as Main
package {
import flash.display.*;
import MenuClass;
public class Main extends MovieClip {
private static var _instance:Main = null;
public function Main() {
_instance = this;
this.addEventListener(Event.ADDED_TO_STAGE, init);
}
public static function getInstance():Main { return _instance; }
public static function getStage():Stage { return getInstance().stage; }
private var Menu:MenuExample = new MenuExample();
private function init(e:Event):void
{
removeEventListener(Event.ADDED_TO_STAGE, init);
//_menu = new MenuExample(stage); //correct way to do it
}
}
}
Thank you.

Adobe AIR getQualifiedDefinitionNames

I have a problem with getQualifiedDefinitionNames, when I compile with AIR 20 I get
Main
gameBg_png$c19135a2672bad8837da970f47c7278f-30390368
and when I compile with Apach Flex 4.15.0 or Adobe Animate CC it returnes everything as expected!
Main
Main__gamebg
how to fix it with AIR, that it returned Main__gamebg class?
my sample code:
package{
import flash.display.MovieClip;
import flash.events.Event;
public class Main extends MovieClip {
[Embed(source="../assets/gameBg.png")]
public const _gamebg:Class;
public function Main() {
super();
if (stage) init();
else addEventListener(Event.ADDED_TO_STAGE, init);
}
private function init(e:Event = null):void {
removeEventListener(Event.ADDED_TO_STAGE, init);
var definitions:*;
if (this.loaderInfo.applicationDomain.hasOwnProperty("getQualifiedDefinitionNames")) {
definitions = this.loaderInfo.applicationDomain["getQualifiedDefinitionNames"]();
for (var i:int = 0; i < definitions.length; i++) {
trace(definitions[i])
}
}
}
}
}
http://forum.starling-framework.org/topic/getqualifieddefinitionnames-porblem?replies=5#post-90611
this trick works.
///////////////
// SomeImage.as
///////////////
[Embed(source="someimage.png")]
public class SomeImage extends Bitmap{
public function get dimensions(): String{
return width + "x" + height;}
}
/////////////
// MyClass.as
/////////////
public class MyClas{
public function foo(): void{
// Instantiate the bound class to get the embedded image
var someImage:SomeImage = new SomeImage();
// ... do whatever you'd like with someImage
trace("Dimensions: " + someImage.dimensions);
}
}

ADDED_TO_STAGE function never called

I have this class which should take a button from stage (xBtn).
package com.stx.utils {
import flash.display.MovieClip;
import flash.events.*;
public class STXbutonx extends MovieClip {
private var xBtn : MovieClip;
public function STXbutonx() {
addEventListener(Event.ADDED_TO_STAGE, init);
}
private function init(e:Event=null) : void {
trace("int!"); //this is never called
xBtn = stage.getChildByName('ics') as MovieClip;
xBtn.addEventListener(MouseEvent.CLICK, onX);
removeEventListener(Event.ADDED_TO_STAGE, init);
}
private function onX(e:MouseEvent) : void {
trace("x Clicked!");
}
}
}
and in Document class I called like this :
import flash.display.MovieClip;
import com.stx.utils.*;
public class Main extends MovieClip {
var xx : STXbutonx;
public function Main() {
xx = new STXbutonx();
}
}
Why my init function is never called?
Thank you!
Because you never add it to the stage.
Change your Document class to
public function Main() {
xx = new STXbutonx();
addChild(xx);
}
Main holds the reference to the stage, adding a child to Main will add the child to the stage. Thus the event listener in STXbutonx will fire.
xBtn = stage.getChildByName('ics') as MovieClip; // now I have acces of undefined property stage...
You don't have access to the stage because STXButon is not on the stage, it is not an DisplayObject. To get around this, do this:
package com.stx.utils {
import flash.display.MovieClip;
import flash.events.*;
public class STXbutonx{
private var xBtn : MovieClip;
private var stage : Stage;
public function STXbutonx(stage:Stage) {
this.stage = stage;
init();
}
private function init() : void {
trace("int!");
xBtn = stage.getChildByName('ics') as MovieClip;
xBtn.addEventListener(MouseEvent.CLICK, onX);
removeEventListener(Event.ADDED_TO_STAGE, init);
}
private function onX(e:MouseEvent) : void {
trace("x Clicked!");
}
}
}
And of course
import flash.display.MovieClip;
import com.stx.utils.*;
public class Main extends MovieClip {
var xx : STXbutonx;
public function Main() {
xx = new STXbutonx(stage);
}
}

How can I dispatch event to another class in Action Script 3?

I've searched few docs and I couldn't find about dispatching event to another classes.
I'm trying to make like this.
'main' class has button.
'main','sub' class gonna trace "button is clicked" when button is clicked
I can trace that in 'main' class with dispatch event.
but 'sub' class is problem.
how can I dispatch event like that into 'sub' class?
Main class
package com
{
import flash.events.*;
import flash.display.MovieClip;
import com.sub;
public class main extends MovieClip
{
public static const BTN_CLICKED:String = "btn_Clicked";
public function main():void
{
if (stage) init();
else addEventListener(Event.ADDED_TO_STAGE, init);
}
public function init(e:Event = null):void
{
var flashVars:Object = {};
removeEventListener(Event.ADDED_TO_STAGE, init);
if(parent != null && parent.parent != null)
{
flashVars = parent. parent.loaderInfo.parameters;
}
else
{
flashVars = this.root.loaderInfo.parameters;
}
//entry point
var subClass:sub = new sub;
subClass.init();
btn.addEventListener(MouseEvent.CLICK, onClick);
addEventListener(BTN_CLICKED, onbtnClicked, false, 0, true);
}
public function onClick(e:MouseEvent)
{
dispatchEvent(new Event(BTN_CLICKED));
}
public function onbtnClicked(e:Event)
{
trace("clicked");
}
}
}
Sub Class
package com
{
import flash.events.*;
import flash.display.MovieClip;
import com.main;
public class sub extends MovieClip
{
public function sub():void
{
if (stage) init();
else addEventListener(Event.ADDED_TO_STAGE, init);
}
public function init(e:Event = null):void
{
removeEventListener(Event.ADDED_TO_STAGE, init);
//entry point
trace("sub class loaded");
}
}
}
You should relocate var subClass:sub to the main set of main class definitions, beside public static const BTN_CLICKED:String = "btn_Clicked";. Then, you can do subClass.dispatchEvent(...).
public class main extends MovieClip {
private var subClass:sub;
public function main() {
...
subClass=new sub();
addChild(subClass); // not just "init()", it's wrong
...
}
public function onClick(e:MouseEvent)
{
dispatchEvent(new Event(BTN_CLICKED));
subClass.dispatchEvent(new Event(BTN_CLICKED));
}
}

Can't dispatch custom event from one class to another in Flash AS3

This is my custom event class:
package{
import flash.events.Event;
public class PetEvent extends Event{
public static const ON_CRASH:String = "onCrash";
public function PetEvent(type:String, bubbles:Boolean=true, cancelable:Boolean=false):void{
super(type, bubbles, cancelable);
}
override public function clone():Event {
return new PetEvent(type, bubbles, cancelable);
}
}
}
This is my game handler. I create a new instance of the class Surf from which I want to listen from.
package {
import flash.display.MovieClip;
import flash.events.Event;
public class GameHandler extends MovieClip {
public var newGame:Surf;
public function GameHandler() {
newGame = new Surf();
newGame.addEventListener(PetEvent.ON_CRASH, onCrash);
addChild(newGame);
}
public function onCrash(petEvent:PetEvent):void{
trace("MPAM");
var gameOver:GameOver = new GameOver(stage.stageWidth, stage.stageHeight);
addChild(gameOver);
newGame = null;
}
}
}
And the relevant lines from the Surf class:
public function startSurfing(timerEvent:TimerEvent):void
{
moveCatandDog();
for each ( var boat:Boat in armada)
{
boat.moveBoat(boatSpeed);
if ( cat.hitTestObject(boat) || dog.hitTestObject(boat) )
{
dispatchEvent( new PetEvent(PetEvent.ON_CRASH) );
gameTimer.stop();
}
}
}
So when Surf detects a crash I want it to send the event to GameHandler and GameHandler will create a GameOver instance.
I have tried everything and I don't even get a trace. I normally don't ask questions but this is for a uni project and I'm running out of time. I would really appreciate any feedback. Thanks!
Problem solved!
I had to change my Document Class to GameHandler and make a public static variable of stage.
Previously I had Surf as my Document Class because I had some keyboard listeners set to the stage.
So the PetEvent and the dispatch in Surf were correct. I changed the GameHandler as shown below, with another solution I found in StackOverflow.
Inside the constructor of GameHandler, if the stage is ready (not null) it sets it to the public static variable STAGE (via the init function), otherwise it adds a listener and when the stage is ready it does the same thing and removes the listener.
package {
import flash.display.MovieClip;
import flash.events.Event;
import flash.display.Stage;
public class GameHandler extends MovieClip {
public var newGame:Surf;
public static var STAGE:Stage;
public function GameHandler() {
if (stage){
init();
} else {
addEventListener(Event.ADDED_TO_STAGE, init, false, 0, true);
}
newGame = new Surf();
newGame.addEventListener(PetEvent.ON_CRASH, onCrash);
addChild(newGame);
}
private function init(e:Event=null):void{
removeEventListener(Event.ADDED_TO_STAGE, init);
// store stage reference when stage ready
STAGE=stage;
}
public function onCrash(petEvent:PetEvent):void{
var gameOver:GameOver = new GameOver(stage.stageWidth, stage.stageHeight);
addChild(gameOver);
newGame = null;
}
}
}
and I imported GameHandler into Surf with:
import GameHandler;
so I can set the listeners in Surf to GameHandler.STAGE.addEventListener (...)
Thanks everyone for the suggestions!

AS3 Dispatch Custom Event from class to class

I want to dispatch a custom event from the Country() sto the MenuButton();
CountryEvent
package {
import flash.events.Event;
public class CountryEvent extends Event {
public static const COUNTRY_HOVERED:String = "onCountryOver";
private var _countryName:String = "";
public function CountryEvent(type:String, countryName:String, bubbles:Boolean=true, cancelable:Boolean=false) {
super(type, bubbles, cancelable);
_countryName = countryName;
}
public function get countryName():String {
return _countryName;
}
public override function clone():Event
{
return new CountryEvent(type,countryName,bubbles,cancelable);
}
}
}
Country Class
package
{
import flash.display.MovieClip;
import flash.events.MouseEvent;
import flash.events.Event;
public class Country extends MovieClip
{
private var countryEvent:CountryEvent;
public function Country()
{
this.addEventListener(MouseEvent.MOUSE_OVER,onMouseOver);
this.addEventListener(MouseEvent.MOUSE_OUT,onMouseOut);
}
private function onMouseOver(e:MouseEvent):void
{
countryEvent = new CountryEvent("onCountryOver",this.name);
dispatchEvent(countryEvent);
}
}
private function onMouseOut(e:MouseEvent):void
{
}
}
}
MenuButton Class
package {
import flash.display.MovieClip;
import flash.events.MouseEvent;
import CountryEvent;
public class MenuButton extends MovieClip {
public var countryName:String = "";
public function MenuButton() {
this.buttonMode = true;
this.addEventListener(MouseEvent.MOUSE_OVER,onMouseOver);
this.addEventListener(MouseEvent.MOUSE_OUT,onMouseOut);
this.addEventListener(CountryEvent.COUNTRY_HOVERED,onCountryOver);
}
private function onCountryOver(e:CountryEvent):void {
if(e.countryName == countryName) {
this.gotoAndPlay(2);
}
}
private function onMouseOver(e:MouseEvent):void {
this.gotoAndPlay(2);
}
private function onMouseOut(e:MouseEvent):void {
this.gotoAndPlay(11);
}
}
}
When a country is hovered a custom event is dispatched which I want the MenuButton to listen and if the parameter passed is the same as its name to get highlighted. The Country Class is the Base Class for my countries movieclips I have on stage and the MenuButton the Base Class for the menu button
It seems that the event never gets through
Thanks in advance
You have to make two modifications:
First, set your event bubbles property to true, so when a Country clip dispatches an event it will go up to the top level.
Then your MenuButtons should listen to stage, not to themselves. So when a Country dispatches an event it goes up to stage and can be caught by the buttons. If you want to listen to the stage you have to do a slight change in your code:
public function MenuButton() {
this.buttonMode = true;
this.addEventListener(MouseEvent.MOUSE_OVER,onMouseOver);
this.addEventListener(MouseEvent.MOUSE_OUT, onMouseOut);
this.addEventListener(Event.ADDED_TO_STAGE, onAddedToStage);
}
private function onAddedToStage(e:Event):void
{
removeEventListener(Event.ADDED_TO_STAGE, onAddedToStage);
stage.addEventListener(CountryEvent.COUNTRY_HOVERED,onCountryOver);
}
the best and easy way for solving this issue is by simply pass the stage reference as class level parameter and add event to the stage reference and dispatch event to the stage reference.
Country Class
package{
import flash.display.MovieClip;
import flash.events.MouseEvent;
import flash.events.Event;
public class Country extends MovieClip
{
private var countryEvent:CountryEvent;
private var _stageRef:Stage;
public function Country(pStageRef:Stage)
{
_stageRef = pStageRef;
this.addEventListener(MouseEvent.MOUSE_OVER,onMouseOver);
this.addEventListener(MouseEvent.MOUSE_OUT,onMouseOut);
}
private function onMouseOver(e:MouseEvent):void
{
countryEvent = new CountryEvent("onCountryOver",this.name);
_stageRef.dispatchEvent(countryEvent);
}
}
private function onMouseOut(e:MouseEvent):void
{
}
}
MenuButton Class
package {
import flash.display.MovieClip;
import flash.events.MouseEvent;
import CountryEvent;
public class MenuButton extends MovieClip {
public var countryName:String = "";
private var _stageRef:Stage;
public function MenuButton(pStageRef:Stage) {
_stageRef = pStageRef;
this.buttonMode = true;
this.addEventListener(MouseEvent.MOUSE_OVER,onMouseOver);
this.addEventListener(MouseEvent.MOUSE_OUT,onMouseOut);
_stageRef.addEventListener(CountryEvent.COUNTRY_HOVERED,onCountryOver);
}
private function onCountryOver(e:CountryEvent):void {
if(e.countryName == countryName) {
this.gotoAndPlay(2);
}
}
private function onMouseOver(e:MouseEvent):void {
this.gotoAndPlay(2);
}
private function onMouseOut(e:MouseEvent):void {
this.gotoAndPlay(11);
}
}
