I managed to put texts on screen now I want to show the text after the button is clicked
but the button does not appear.
Here is the code.
package
{
import flash.events.MouseEvent;
import flash.media.Camera;
import mx.controls.Button;
import flash.display.Sprite;
import flash.text.TextField;
public class test2 extends Sprite
{
private var tField:TextField;
public function click(e:MouseEvent):void
{
tField = new TextField();
tField.text="ffff";
addChild(tField);
}
public function test2():void
{
var aa:Button=new Button();
aa.label="deneme";
aa.x=100;
aa.y=200;
aa.addEventListener(MouseEvent.CLICK, click)
}
}
}
You need to alter the test2 function to actually add the button to the stage:
addChild(aa);
You forgot to add the Child to the stage. After setting the position you still need to do addChild(aa);
public function test2():void
{
var aa:Button=new Button();
aa.label="deneme";
aa.x=100;
aa.y=200;
aa.addEventListener(MouseEvent.CLICK, click)
addChild(aa);
}

I'm gonna try explaining my situation with images, to make sure that everyone will understand what i want to succeed.
First of all i have 3 files:
GenImage.fla which is linked to class GeneralImage.as
and it only contains the following picture (I tried to make the image Movie Clip but again it's not working):
Pic1
and a file named ScrollUI.as which contains the class ScrollUI.
What i want to succeed is from my GeneralImage class to create a ScrollUi item, pass the stage, and there create a ScrollPane which makes the picture look like this:
Pic2
The center part of the second image is the ScrollPane Component, which i need to make it Scrollable through the whole image. I managed to get it in my screen but i can't put the Stage in it and make it scrollable.
These are my codes :
GeneralImage.as
package {
import flash.display.*;
import flash.events.*;
import flash.display.Stage;
import ScrollUI;
public class GeneralImage extends MovieClip
{
public function GeneralImage()
{
var k = new ScrollUI();
k.ScrollConstructor(this);
}
}
}
ScrollUI.as
package
{
import flash.display.*;
import flash.events.*;
import fl.containers.ScrollPane;
import fl.events.ScrollEvent;
import fl.controls.ScrollPolicy;
public class ScrollUI extends MovieClip
{
private var _mainStage:Stage;
var aBox:MovieClip = new MovieClip();
var aSp:ScrollPane = new ScrollPane();
public function ScrollUI()
{
}
function ScrollConstructor(stage:Object):void
{
_mainStage = (stage as MovieClip).stage;
aBox == stage as MovieClip;
aSp.source == aBox ;
_mainStage.addChild(aBox);
aSp.setSize(300,300);
aSp.move(150, 75);
aSp.scrollDrag = true;
aSp.horizontalScrollPolicy=ScrollPolicy.OFF;
_mainStage.addChild(aSp);
}
}
}
So what i want it to set the Source of the Scroll Pane ( which is named aSp ) to be the _mainStage which is the stage i get from GeneralImage
Your issues is likely these two lines:
aBox == stage as MovieClip;
aSp.source == aBox ;
You're doing a comparison by using two ==, which effectively does nothing in your case. Use a single = to assign a value.
This is how I would suggest you approach this:
In the FlashPro library, find your image asset (I'm going to assume you have it wrapped in a MovieClip), right-click (or command click) and go to it's properties. Check the "export for actionscript" box, and give it a meaningful class name (for my example, I'll assume you called it MyImage)
Then you could do the following:
ScrollUI Class
package
{
import flash.display.Sprite;
import fl.containers.ScrollPane;
import fl.events.ScrollEvent;
import fl.controls.ScrollPolicy;
public class ScrollUI extends Sprite
{
//just declare the variables here, don't assign them new values
private var aBox:MovieClip;
private var aSp:ScrollPane;
public function ScrollUI()
{
//use the actual constructor...
aSp = new ScrollPane(); //instantiate a new scroll pane
addChild(aSp); //add the scroll pane to the display
aBox = new MyImage(); //instantiate an new MyImage from the library
//set the scroll pane properties
aSp.source = aBox; //you had two = signs here before, which doesn't actually assign anything it compares
aSp.setSize(300,300);
aSp.move(150, 75);
aSp.scrollDrag = true;
aSp.horizontalScrollPolicy=ScrollPolicy.OFF;
}
}
}
Document Class
package {
import ScrollUI;
public class GeneralImage extends MovieClip
{
public function GeneralImage()
{
var k:ScrollUI = new ScrollUI(); //create a new instance of the ScrollUI class
addChild(k); //add the scrollUI object to the display;
//OR, you just do this:
//addChild(new ScrollUI());
}
}
}
You could also just set the .source property of the scroll pane to the physical path of your image.
I found the solution, Thanks Batman for his help, I changes some things into my code and the program is working.
First of all as Batman said , In my GenImage.fla i made the logo a MovieClip and i named it "wholemap"
Here are my codes :
GeneralImage.as
package {
import flash.display.*;
import flash.events.*;
import flash.display.Stage;
import ScrollUI;
public class GeneralImage extends MovieClip
{
//as Batman indicated, I should have used the ScrollUI constructor, but
//except for the Stage, i also send the wholemap that is in my GenImage.fla
//<< this.getChildByName("wholemap") as MovieClip) >>
public function GeneralImage()
{
var k = new ScrollUI(this, this.getChildByName("wholemap") as MovieClip);
}
}
}
ScrollUI.as
package
{
import flash.display.*;
import flash.events.*;
import fl.containers.ScrollPane;
import fl.events.ScrollEvent;
import fl.controls.ScrollPolicy;
public class ScrollUI extends MovieClip
{
private var _mainStage:Stage;
var aBox:MovieClip = new MovieClip();
//So our constructor gets 2 items, a Stage, and a MovieClip
public function ScrollUI(stage:Object, pic:MovieClip)
{
//We set the Stage at the variable _mainStage with that way:
_mainStage = (stage as MovieClip).stage;
//We set the Image that we will take at our clip variable :
var clip:MovieClip = pic;
//And we send the Movieclip (clip) in our ScrollConstructor function
ScrollConstructor(clip);
}
function ScrollConstructor(Clip:MovieClip):void
{
var aSp:ScrollPane = new ScrollPane();
aBox = Clip;
_mainStage.addChild(aBox);
aSp.source = aBox ;
aSp.setSize(300,300);
aSp.move(150, 75);
aSp.scrollDrag = true;
aSp.horizontalScrollPolicy=ScrollPolicy.OFF;
aSp.verticalScrollPolicy=ScrollPolicy.OFF;
_mainStage.addChild(aSp);
}
}
}
Thank you very much for your assistance, I hope if someone else come across with this problem to be able to solve it with this Answer
Let me explain my situation:
We have a file named Main.fla which links to the class MAIN( it's included in the MAIN.as file). I also have a secondary User.as file with a User class.
I managed to import a classic swf button to my stage from the User.as class but i'm finding trouble on adding the pop up window, when the button is clicked. Here are the codes:
MAIN.as
import flash.display.*;
import flash.net.*;
import flash.events.*;
import User; //Importing our User class
public class MAIN extends MovieClip
{
public function MAIN()
{
var k = new User();
k.logocons(this); //This function is made on User class and
//it takes a stage:Object as definition
}
}
User.as
import flash.display.*;
import flash.net.*;
import flash.events.*;
public class User extends MovieClip
{
var myLoader:Loader = new Loader();
public function User()
{
var url:URLRequest = new URLRequest("C:/Project/Button.swf");
myLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, swfLoaded);
myLoader.load(url);
}
function swfLoaded(event:Event):void
{
myLoader.x = 50;
myLoader.y = 50;
}
public function logocons(stage:Object)
{
stage.stop();
stage.addChild(myLoader);
}
}
This works normally so far When i test the file the Button works perfectly
What i want now is when the button is clicked to show at my MAIN.Stage a pop up window which is also in the same folder named PopUp.swf.
I tried really many things but i couldn't find how i can access the MAIN.stage from another class.
Thanks in advance
User.as
import flash.display.*;
import flash.net.*;
import flash.events.*;
import fl.motion.MotionEvent;
public class User extends MovieClip
{
var myLoader:Loader = new Loader();
private var _mainStage:Stage;//MAIN.stage
public function User()
{
var url:URLRequest = new URLRequest("C:/Project/Button.swf");
myLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, swfLoaded);
myLoader.load(url);
}
function swfLoaded(event:Event):void
{
myLoader.x = 50;
myLoader.y = 50;
}
public function logocons(stage:Object)
{
_mainSage = (stage as MovieClip).stage;// now you can use _mainStage anywhere on User class.
stage.stop();
stage.addChild(myLoader);
}
private function onButtonClick(e:MouseEvent){
//ex. _mainSage.addChild(popWindows);
}
}
So, my menu for my game is in a separate .fla file and I have used a loader like so to load the menu into my game:
package {
import flash.display.MovieClip;
import flash.display.Sprite;
import flash.display.DisplayObject;
import flash.display.Stage;
import flash.events.Event;
import flash.events.MouseEvent;
import flash.events.TimerEvent;
import flash.utils.Timer;
import flash.ui.Mouse;
import flash.media.Sound;
import flash.media.SoundChannel;
import flash.text.TextFormat;
import flash.text.TextField;
import flash.display.Loader;
import flash.net.URLRequest;
import flash.net.URLLoader;
import flash.system.LoaderContext;
import flash.display.Sprite;
import flash.net.Socket;
import caurina.transitions.Tweener;
public class Main extends MovieClip {
public static var gameLayer:Sprite = new Sprite;
public static var endGameLayer:Sprite = new Sprite;
public static var menuLayer:Sprite = new Sprite;
public var gameTime:int;
public var levelDuration:int;
public function Main()
{
addChild(gameLayer);
addChild(endGameLayer);
addChild(menuLayer);
var myMenu:Loader = new Loader();
var url:URLRequest = new URLRequest("Menu.swf");
myMenu.load(url);
myMenu.contentLoaderInfo.addEventListener(Event.COMPLETE, menuLoaded);
function menuLoaded(event:Event):void
{
menuLayer.addChild(myMenu.content);
}
playBtn.addEventListener(MouseEvent.CLICK, startGame);
}
public function startGame(e:Event)
{
// Code to remove the menu (menuLayer.removeChild?)
// Code here to start timers etc
}
I set instance names for my buttons but when I try to do something like menuLayer.playBtn.addEventListener(MouseEvent.CLICK, startGame);, I get messages saying Access of undefined property playBtn.
Now, I double checked on my Menu.fla and I definitely gave the button an instance name of playBtn but it's not working. Any help please? Might be something really obvious I've missed but I'm not sure what.
EDIT: Trying it another way (Converting the menu to a movieclip) but not 100% sure how to do it exactly. The code I have is:
public class Main extends MovieClip {
var mainMenu:menuMain = new menuMain;
// Other variables
public function Main()
{
addChild(gameLayer);
addChild(endGameLayer);
addChild(menuLayer);
menuLayer.addChild(mainMenu);
mainMenu.addEventListener(Event.COMPLETE, menuLoaded);
}
function menuLoaded(event:Event):void
{
//var mainMenu:LoaderInfo = event.currentTarget as LoaderInfo;
//var menuInstance:MovieClip = menuLayer.getChildAt(0) as MovieClip;
// now you can actually add the listener, because the content is actually loaded
mainMenu.playBtn.addEventListener(MouseEvent.CLICK, startGame);
}
public function startGame(e:Event)
{
// Code to execute timers etc.
}
My guess is that you think that when you go menuLayer.addChild(myMenu.content) that menuLayer suddenly becomes an instance of menu.swf That is not the case. It becomes a child of menuLayer.
Try this :
menuLayer.addChild(myMenu.content);
var menuInstance:MovieClip = menuLayer.getChildAt(0) as MovieClip;
trace (menuInstance.playBtn);
This code assumes that you have nothing else added to menuLayer and in that case your menu.swf content would be the only child on the display list of menuLayer.
I am also assuming that menu.swf's contents are a MovieClip.
If my assumptions are wrong, this may not work.
I also noticed that you have your menuLoaded method inside your constructor. Not a good idea. Especially since the next line is expecting playBtn to exist and the menu hasn't even been loaded.
Try something like this :
public function Main()
{
addChild(gameLayer);
addChild(endGameLayer);
addChild(menuLayer);
var myMenu:Loader = new Loader();
var url:URLRequest = new URLRequest("Menu.swf");
myMenu.load(url);
myMenu.contentLoaderInfo.addEventListener(Event.COMPLETE, menuLoaded);
}
function menuLoaded(event:Event):void
{
var myMenu:LoaderInfo = event.currentTarget as LoaderInfo;
menuLayer.addChild(myMenu.content);
var menuInstance:MovieClip = menuLayer.getChildAt(0) as MovieClip;
// now you can actually add the listener, because the content is actually loaded
menuInstance.playBtn.addEventListener(MouseEvent.CLICK, startGame);
}
public function startGame(e:Event)
{
// Code to remove the menu (menuLayer.removeChild?)
// Code here to start timers etc
}

I have a problem with the btn:Button
You should use the import statement to import "Button"
Depending on your requirements it could either be
Spark Button
import spark.components.Button;
MX Button
import mx.controls.Button
UPDATE: Looks like this page has an answer to your question. Specifically check THIS answer
you problem is your class PencereyiGizle is looking for a button to be passed as a reference in the constructor which you are not doing
var firat:PencereyiGizle= new PencereyiGizle();
addChild(firat);
you need to pass either an instance name of a button
var firat:PencereyiGizle= new PencereyiGizle( someButton );
addChild(firat);
or create a new button and pass it along
var someButton:Button = new button
var firat:PencereyiGizle= new PencereyiGizle( someButton );
addChild(firat);
For starters let me just say that I am very new to action script and also that I'm not using adobe creative suite, I am using notepad with flex as a compiler. I have two classes, a main class and a class called OBJECT_square.
Here is the MAIN class:
package
{
import flash.display.*; import mx.core.*;
import flash.events.*; import mx.collections.*;
import flash.geom.*; import mx.controls.*;
import flash.text.*; import mx.events.*;
import mx.styles.*;
import mx.containers.*;
public class MAIN extends Sprite
{
public var APPLICATION:Application = Application(Application.application);
public var keyDownText:TextField = new TextField();
public function MAIN()
{
stage.addEventListener(KeyboardEvent.KEY_DOWN,KEY_DOWN);
addEventListener(Event.ENTER_FRAME,STEP);
this.addChild(new OBJECT_square().CREATE(10,100,1));
this.addChild(new OBJECT_square().CREATE(10,200,1));
}
public function STEP():void {}
public function DRAW():void {}
public function KEY_DOWN(event:KeyboardEvent):void
{
keyDownText.text = "Key code: " + event.keyCode;
this.addChild(keyDownText);
}
}
}
Here is the OBJECT_square class:
package
{
import flash.display.*;
import flash.events.*;
public class OBJECT_square extends Sprite
{
public var X:int = 0;
public var Y:int = 0;
public var DEPTH:int = 0;
public var SPRITE:Sprite = new Sprite();
public function CREATE(X:int,Y:int,DEPTH:int):Sprite
{
addEventListener(KeyboardEvent.KEY_DOWN,KEY_DOWN);
this.DEPTH = DEPTH;
this.X = X;
this.Y = Y;
DRAW();
return SPRITE;
}
public function KEY_DOWN(event:KeyboardEvent):void
{
if (event.keyCode == 39) {X += 1; DRAW();}
}
public function DRAW():void
{
SPRITE.graphics.beginFill(0xFF0000,1);
SPRITE.graphics.drawRect(X - 10,Y - 10,20,20);
SPRITE.graphics.endFill();
}
}
}
Now my problem is this. Simply put I would like the square that OBJECT_square draws to move right when I press the right arrow key. Right now I can only get it to be drawn once (though I am actually creating two separate squares in two different spots). Now the thing I need to know is if I have used the keyboard event correctly in OBJECT_square. I used keyboard event in the main class as well to display the last key I pressed but I'm not sure how to use it in a class other than the main one. Also I'm not sure how to 'update' the square so that it is redrawn when it moves, that is remove its old self from the display list and reinsert its new self. The whole kinda point to the code is that the square be 'self-sufficient', ie contains all the code needed to draw it and move it rather than relying on any other class. I basically want it so that once another class has made a square the square is capable of doing everything else on its own.
You don't need to keep manually redrawing the square. Sprites have x and y properties that you can change and will automatically be moved. There is also no reason to be creating a sprite inside a class that is already extending sprite. There are a couple of other weird things you are doing so a fixed up version of your class would look something like:
package
{
import flash.display.*;
import flash.events.*;
public class ObjectSquare extends Sprite
{
public function ObjectSquare (x:int,y:int):void
{
graphics.beginFill(0xFF0000,1);
graphics.drawRect(x,y,30,30);
graphics.endFill();
addEventListener(KeyboardEvent.KEY_DOWN,KEY_DOWN);
}
public function KEY_DOWN(event:KeyboardEvent):void
{
if (event.keyCode == 39)
{
x += 1;
}
}
}
}
package
{
import flash.display.*; import mx.core.*;
import flash.events.*; import mx.collections.*;
import flash.geom.*; import mx.controls.*;
import flash.text.*; import mx.events.*;
import mx.styles.*;
import mx.containers.*;
//rename your class to Main. Should not be all caps
public class Main extends Sprite
{
public var APPLICATION:Application = Application(Application.application);
public var keyDownText:TextField = new TextField();
public function Main()
{
stage.addEventListener(KeyboardEvent.KEY_DOWN,onKeyPress);
addChild(new ObjectSquare(10,100));
addChild(new ObjectSquare(10,200));
}
public function onKeyPress(event:KeyboardEvent):void
{
keyDownText.text = "Key code: " + event.keyCode;
this.addChild(keyDownText);
}
}
}
You would probably be better off creating a class to handle all your keyboard inputs and then change the relevant objects.
