Let's say I have a class, and I created a new object of this class in my document class. Inside this class, there is a public variable. How would I be able to detect a change in that public variable?
View 7 RepliesI have a simple problem. I have two document classes. One is Main.as the other is Step2.as. I want to declare a public variable in Main.as then need to give it a value from Step2.as. That value will later be used in my next Document class Step3.as How would I write the code that gives the value in my Step2.as and then how would I write the code that retrieves the value in my Step3.as?
Note I can't import my Step2/ or Step3 document class into my Main.as.
Can I detect a change to a variable (a data string)?
I am making a AS2 SWF (player level 7) with a combobox page navigation. I have a page name variable that I am changing from outside of the SWF with Director and Authorware using (I believe) FlashVars. The variable (internally) is set by default during SWF initialization. The external variables values allowed are always one of the combobox's data field values. The combobox default variable is not always index positon 0 (zero). Or the order of the data either. The variable can get changed internally by the nav combobox used for navigation independent of the external variable. - this works When the shared nav var is changed from the external source, the combobox needs to change to the match the corresponding combobox's data variable. This is what I am trying to do. I can change the combobox setting programatically (index) but not get it to recognize it as a change event. Or tell it programatically
Can the combobox be selected by the data variable or is the only option to use the index (and loop through index values to match variable to data field)?
And update the combobox selection (and as a result the nav page) by triggering a change event programatically?
Detecting the var change cleanly without the OnEnterFrame trick is my goal - if it even works in the version I have to use (flash palyer 7).
I define a global variable in a swf and then launch a child window which will alter the value of the global variable and I want the parent to detect that event and take specific action. How should I go about this? Can global variables launch events?

View 3 RepliesI've got two classes running...one is a document class (EgoGame.as) and another is a class linked to several similar movie clips (Ball.as).I'm trying to access a public variable from Ball.as which has been declared in the doucment class EgoGame.as.When I run the test the outputs states the following...1120: Access of undefined property _ballPlaced.Here's my code. What I'm trying to do is remove the event listeners from the Ball.as when the _ballPlaced variable is true, so that the user can't drag and drop the balls after they've been placed in a zone.

I've created 2 public variables in my Document Class...
public var _wall1:Wall=new Wall();public var _wall2:Wall=new Wall();I've then added them to the stage and given them relevant instance names...
stage.addChild(_wall1);_wall1.x=32; _wall1.y=510;_wall1.name = "wall1";I then want to use these variables in another Class (Ball.as). They need to be accessed in a function within the Ball Class constructor.
function bubble(event:Event):void{if(this.hitTestObject(_wall1)){ this.x += 1;}else if(this.hitTestObject(_wall2)) { this.x -= 1;}However, the following Error message keeps appearing...
1120: Access of undefined property _wall1.1120: Access of undefined property _wall2.Any pointers? Do I need to import something into the Ball Class to point to the _wall# public variables in the Document Class?
I have a base class like this
class Base {
public var space:Number;

which gets extended by
class Desc extends Base {

This doesn't compile. Say, you don't have control of the base class, what ways is there implement the same thing? The obvious is create a function setSpace(), but this object is being embedded in an already existing system that use the public space.
display an variable to the public, also use variable in middle of string.

finally have a working hitTest (YAY!!!!), now, my code is setup to create 3 'sasquatches', the problem is for the hitTest to work, the variable "one" has to be public. Now, in the next bit of code we create 3 instances of one using a for loop, BUT they all three are in the same spot cause I can't figure out how to pass Random numbers to the variable each time it creates.
Code:
package{
import flash.display.*;
import flash.events.*;

I think I've made some fundamental error here... I have a public variable a in class A, and I want to access it in class B, but I cant (access of possibly undefined property...) now every time I want to refer to a variable in class A I need to pass the variable reference to class B's constructor

View 1 Repliesi've got two classes and i'm not extending to MovieClip. I like to attach the mc in the constructor just because i'll be working with different MC's that have the same purpose.
however, im using private var loadedMC:Movieclip and now i've got another class that needs to be able to access the instance's variable.
for example, myClass.loadedMC , but this would mean having to make it public and I rather not go that route.
I have the below script as part of a small application I'm building. The script just creates cue-points along a movies timeline so we can add events etc to those cue-points.
[Code]....
It's creating the cue-points well, although I'd like to use the below variable outside of this function.
Code: var stampName When I try and use it I get an access of undefined property error, which I believe relates to the variables being private and within the function - but I can't seem to find a method to get this varibale public.
I'm trying to make this fluid preloader that uses tween classes to change the size of the bar instead of just using something likegotoAndStop(percent)I have the tween class working but need a way for it to detect the change of the percentage variable. Here's what I'm trying to get it to do:Current percentage is at 55, this is set as the "currentPercent" variable. It suddenly jumps to 65%, the "currentPercent" variable would change to 65 while the "prevPercent" variable would stay at 55 so the tween class could have a beginning and ending value.

View 6 RepliesWhat event would signal that the visual content of an SWFLoader had changed or how would you detect that.
Actually if the visual content changes there is in fact a "render" event broadcast in the parent application, but I don't know how to determine which SWFLoader caused it.
Say you have one SWFLoader on a page that contains some sort of input control but its just sitting there doing nothing until a user presses something on it, and then there is a render event in the parent application. However, if there is another SWFLoader that contains a continually playing VideoDisplay, then there will be continal render messages being broadcast in the parent application (I verified this.) My point being that the parent application is getting signaled somehow the instant the visual content of some embedded SWFLoader changes. But the question is how does my code determine specifically which SWFLoader changed.
I thought this would be easy but I don't seem to be getting anywhere. I've got a button with a text field in it, simple old dynamic one, not an input. I need to be able to change the htmlText value of that text field and detect it so I can change the size of the button to fit. I thought using Event.CHANGE would do it but I'm not getting the callback:
Code:
private function setListeners():void{
this.btn_text.addEventListener(Event.CHANGE, textChange);

i want to center some dynamic numbers in a circle... but of course it won't align properly when there a more digits. So i need to know how many digits there are in order to offset the numbers to center.

View 2 RepliesI have been banging my head against a brick wall regarding the following problem which must be very simple to fix, just can't see the answer.I have a class assigned to a movieclip called canvas. The class is called drawClass. I have called the instance of canvas on the stage 'drawingCanvas'.When I trace "drawingCanvas" I get object drawClass] which is fine. Tracing drawingCanvas.name gets me the instance name 'drawingCanvas'.This is a String variable.Basically what I am trying to do is pass the MovieClip name to another class. In my example the class 'toolBar', which can then interact with the MovieClip.
The problem is passing 'drawingCanvas.name' results in a String, so I get an error saying :TypeError: Error #1034: Type Coercion failed: cannot convert "canvasArea" to flash.display.MovieClip.I can't for love or money find a way to convert a String variable to a MovieClip variable! I have the name of the MovieClip, I just need to tell the toolbar class. But I can't find a way of doing this as the instance on stage is an object of drawingClass, not a MovieClip (unless MovieClips with attached classes are not treated as standard MovieClips?).
I'm trying to achieve something i thought would be extremely easy, but i can't get it to work!

is it better to use public variables or public static variables?
View 6 RepliesI'm creating a board game which has 3 variables, p1Move, p2Move and activePlayer.
p1Move and p2Move store the p1 and p2 location on a game board. activePlayer stored who's turn it is at the moment.
I am loading a value in from a text file which changes the value of move. This all works fine when i designate a player directly:
ActionScript Code:
p1Move = [insert variable name],
but i want to designate dynamically based on who's turn it is.
Something like this:
ActionScript Code:
_root["p"+activePlayer+"Move"] = Number(this.varAmount);
so that flash changes the value of p1Move (or p2Move depending on who's turn it is) to varAmount. varAmount is the variable being read from the textfile.
Hopefully that all makes sense. Basically i want flash to change the variable associated with the active player only.
I have an flash movie with on the main timeline a movieclip "MC1". In this movieclip I have another movieclip "MC2". On the first frame of MC1 I have declared a variable x and I want to give this variable a new value when I click on MC2 but it doesn't work?!
Main timeline: 1 frame with MC1
MC1: 1 frame with MC2
Codes implemented on the timeline:
MC1:
x;
MC2:
onMouseDown = function() {
_root.x=1;
}
