I create a Sprite in a subclass, add it to the stage. Now I need to target it from another class, but I am going wrong somewhere. This is shorten code, so hope I did not delete some important parts. But you should be able to follow the basic structure.
Main class:
package myClasses
{
import flash.display.Sprite;
import flash.display.Stage;

I have my main.swf which has class of Main.as which control everything.Then in main.swf I have 3 movieclips that acts as a button and they share a class of Button.as which controsl all the button functions btn1, btn2,bt3 are all place on stage and in Main.as I control their positions.When you click on a btn, it moves to a new location at the same time the other 2 btns will move as well.I can get the target btn that's been click to move just fine, but I can't get the other 2 btns to move and they all share the same class. I know this probably has to do with a targetting issue... I think. Is there a way I can make the connection in same Button.as class file? Or do I use like some global event dispatch?

ActionScript Code:
public class Chart extends Sprite {
public function Chart(myHeight:Number, myWidth:Number) {

In a previous thread I asked a question about setting the width and height of a sprite subclass in its constructor method. One of the responses has puzzled me since I read it:
"Setting width and height only makes sense if you're adjusting the width and height of existing content, and the Chart (Sprite) has none at that point."
I don't understand that; what if you're adding children to the sprite that depend on those dimensions?
Here's a simple app which draws a red circle inside of a blue box which demonstrates my confusion as well as one other issue. The full questions are at the bottom.
Main.fla:
import Box;
var myBox:Box = new Box(200, 200);addChild(myBox);myBox.drawCircle();
[Code].....
Question 2: In this example, the dimensions of Circle are based on the width of its parent Box sprite. Is there a more elegant way to pass the dimensions to the circle? I ask because in my actual project (a chart) the plot area contains a lot of screen locations that must be passed around when I add new objects such as grid lines and markers and passing around the coordinates as parameters seems awfully messy. I'm just not sure how else to do it.
I've created a wrapper around Sprite called ClickableCircle, which is meant to add itself to the display list when instantiated. Here's a toy version:
public class ClickableCircle extends Sprite {
protected var circle:Shape;
protected var myName:String;

Say i have these two classes:
MAIN.as

import flash.display.*; import mx.core.*;
import flash.events.*; import mx.collections.*;

Now how is it that I can add the variable SPRITE which is a Sprite in the OBJECT_square class to the display list of MAIN class? I've tried addChild(SPRITE) and super.addChild(SPRITE). If everything works I should see a red square somewhere on the screen but right now its all blank, except for the text drawn in the MAIN class.
Basically I want it so i can just make a new OBJECT_square and it will draw itself without any more instructions from the MAIN class.

Can I access a static variable of a subClass' subClass? I don't want to instantiate it, just looking to get the variable because it has already been initialized by the subClass.example:

i am trying to do a simple blackboard on mouse down, start drawing on mouse move, if drawing, draw line on mouse up, stop drawing i set the listeners on a simple clip with a rectangle. if i dont fill the rectangle, the mouse events wont fall into the rectangle, but if i fill the rectangle, it will paint behind the rectangle, so anyway i wont see any succesfull results. what i did was create another sprite and paint within it; something like

I created a class, extended the sprite class, and now in the constructor I am trying to set the Sprite's width and height properties which are inherited from the DisplayObject. However, after I set this.width and this.height, and print the values, I get 0 for both.
What the heck is going on? When I view the livedocs I see that DisplayObject has width and height listed as public properties. I have been able to instantiate a Sprite directly, and set the width and height after it's been instantiated, so I don't get it.

I'm doing a simple rotation on a sprite but there's a weird behavior where the sprite does not rotate around it's top left. I think I'm rotating along the top left of the test class instead of the sprite child. I would like to rotate the rectangle around it's top left corner (kinda like a clock hand). The code is pretty short so I'll let the code + pictures explain my problem:
package
{
import flash.display.Sprite;
[Code]....
I've read a lot of stuff about rotating around a fixed point, I've tried doing it with movieclips instead of sprites, I even copy pasted a tutorial on rotation and nothing works.

Then the numericStepper is drawn as if it is squished to 20% its normal height. If I pre-set mySprite width and height before adding the numericstepper, the trace output is 0,0 after adding it and it is not displayed at all. Is there some way I can make the sprite only adjust to correctly fit the numericStepper OR resize it afterwards without distorting the numericStepper component?
Both of sprite.width and sprite.scaleX can be used for scale a sprite. Is possible sprite.scaleX depends on screen size?

View 2 RepliesEverytime I google this question I see confusing information about masks and blends, none of which seems to directly apply to what I think should be an easy thing... There are three Sprites involved here...the lowest layer sprite is pretty much a background. I want to overlay a translucent Sprite on top of the background and then I want the third, top-most Sprite to act as a hole, so that the area inside the third Sprite is completely transparent, so that the background sprite is completely visible. How would I go about doing this dynamically (i.e. dynamically drawing the masking sprite and hole using the Actionscript graphics calls)?
View 4 Repliesqi have a movieclip which is added to the stage:
var profileholder:profileHolder=new profileHolder ;
inside of profileholder is another movieclip(infoBtn) that acts as a button.when the mouse is over profileholder i want to do something with infoBtn like:
//profOver is the over state of profileholder
function profOver(e:Event) {
e.target.infoBtn.alpha=1;
}
this doesn't work and brings up this error:ReferenceError: Error #1069: Property infoBtn not found on flash.display.Loader and there is no default value.
at main_fla::MainTimeline/profOver()
i also tried:
function profOver(e:Event) {
var item:profileHolder=e.target as profileHolder;
item.infoBtn.alpha=1;
}
and get this error:TypeError: Error #1009: Cannot access a property or method of a null object reference.
I have a document class and a subclass. In the subclass I have a trace. I've done this dozens of times before.I've checked everything and I'm stumped. I can't for the life of me figure out why it's not running a trace.

View 9 RepliesI am building a app that pulls data from xml. The different nodes in the xml needs to build different objects. My thinking was that I must import the xml only once. Then build seperate classes for each object type. These classes will extends the xml class and apply whatever it needs to do with specific nodes data. Problem is that it seems like the subclass is created before the xml loaded. I can trace the xml data from the xml superclass but not from the subclass.

How do you subclass multiple classes. I have a class that subclasses MovieClip. I added a new feature. Now its yelling that my class needs to subclass SimpleButton. I know there both part of the display class. But how do you subclass that?
View 1 RepliesI'm running into the situation where I can't instance a SubClass in the above SuperClass because the SubClass is extending from the SuperClass.
I get stack overflow. Fair enough, right?
Well, I want to add this SubClass to the display, and the only way I know how to do that is through addChild(). To addChild() I need to instance the SubClass.
I can't put any visual display instance or events in this subclass because it's currently null and extends is keeping me from doing so. It's great cuz I can share all the goods, but now I'm stuck dancing inside functions because I can't use events on the main "timeline" of the null SubClass.
I am calling on different types classes from within a loop. The objects can be of different types so therefore I am using the getDefinitionByName method. here is a piece of my code:
for(var y = 0; y < mapH; y++)
{
brickHolder[y] = new Array();
[Code]....
But I got an error when I tried to call on methods. The interface is blank; doesn't have any methods in it. I am not sure if that makes a difference. But the parent class inherits it and the subclasses inherit the parent class. Can I instead use the parent class?
var brick:ParentBrick2 = ParentBrick2(new classRef());
In a nutshell, what can I do to loosely cast these objects so I am able to use any subclass methods that get called?
I want to subclass "superClass" and override one of it's functions.
