View 2 RepliesI am trying to use AMF PHP to pass variables to a flash file, thus far I cannot see anything wrong with my code, but I have very little experience with creating classes, so here it goes, here is my code,
index.php:
<?php
include "amfphp/services/flashMe.php";
$session = true;
[Code].....
Flash is looking for the flashMe class and the push method within that class, but I keep getting null variables in my flash file when I run it
Code:
var myOnStageClip:MovieClip = this.fileInstanceMC;
var myLinkage:Class = Class(getDefinitionByName(getQualifiedClassName(myOnStageClip)));

When I set the following class as my document class it works (draws a rectangle) but when I don't set it as my document class and instead instantiate it using var myRec:simple_shape = new simple_shape(); in first frame of my timeline nothing happens no rectangle and no error either). why and how I can get it to work without setting it as my document class?

I asked yesterday how to call a function from an XML file, and I figured out how to make that work using the string-to-function call.so in my XML file I have <ITEM CALLBACK="ContactsList">View All</ITEM>, and my TextMenu class parses the XML file and creates my navigatable text menu instance. When enterMenu():String is called, it looks to see if the CALLBACK attribute has a value, and if so it returns it as a String.so..
var callbackFnc:String = textMenu.enterMenu();
if(callbackFnc != null)

I am loading one swf into another using the Loader class, but when the child swf finishes loading and is added to the display list, its Document Class is not instantiated. I have a few trace statements that should execute when the object is created, but nothing is happening when loaded into the parent SWF. When I compile the child SWF on its own, the Document Class runs as expected.
So I'm wondering... how do I associate a child SWF's Document Class with Loader.content?
[Code]...
Is there a way I can load a swf file but not automatically instantiate it's DocumentClass? Instead I want to do something like the following:
protected function mainLoaded(e:Event = null):void {
trace('mainLoaded');
var main:* = this.mainLoad.createClassByName('Main');
trace(main);
}
Where mainLoad is an instance of CasaLib's SwfLoad and createClassByName is the equivalent to
loaderInfo.applicationDomain.getDefinition();
The thing is that when my swf finishes loading I can see it is created, because of some trace calls, although its obviously not added to the display list.
Here is the code:
ActionScript Code:
private class someFunction(classRef:Class):void
{
try
{
var instance:Object = new classRef();

Can I perform the check without instantiating?
I've got a confusing situation which wont seem to fix itself basically I have my main class, my iContent class (which will hold each page and have functions for all pages), and my individual pages.
The homepage is instantiated by calling the iContentClass.goHome method in the main document class. The home page contains a button to go on to the next page. This button references the goColourBrowserPage function within the iContentClass, which removes the child (being the home page) and attempts to add a child (colourBrowserPage).
For some reason this doesnt work! It doesnt seem to add the child and wont let me remove the child of the home page! I've been sitting here for 3 hours trying to work it but to no avail!

Is there a way to declare and instantiate an array using constants as indexes? I want to do something like:
public var arr:Array = new Array([ CONSTANT_A : "helloWorld", CONSTANT_B : "helloGoodbye" ]);
In php one could do:
$arr = array(CONSTANT_A => "foo", CONSTANT_B => "bar");
I'm making an app with pages set out as classes which extend the MovieClip class.
What I've got are back buttons and different pages which go to the same page, however... If I end up going out of a page and back into a page (specifically one with drawn squares and dynamic text boxes called from a web service), it seems to have kept all of the original information.
So far I've tried killing all of the children with a while loop targeting the index and also using weak event listeners - neither is working!
If I only instantiate a class once should I make its vars static? I understand how this is of benefit if I make multiple classes, clearly you use less memory as it creates a reference to the same place for each class. Are there any other benefits for creating static vars or functions ?
For example I have my class 'MainMenu' which I create once (might even be my document class). In it I create a
Code:
private var someHolderForStuff:Sprite = new Sprite();
Should I rather create
Code:
private static var someHolderForStuff:Sprite = new Sprite();
I have a MovieClip symbol that has 2 frames (for now). Depending on how it was initilialized, I want it to gotoAndStop at either frame or 2.Inside my class definition (Animal.as), I have written this as my constructor:
var type:String;
public function Animal(t:String = "") {
type = t;
[code]....
Let's say I have a defined ClassA. ClassB extends ClassA and there's a Movie Clip instance on the stage linked to ClassB. How would ClassC access the properties and methods of ClassB without extending ClassB or creating a new instance of ClassB? The way I'm currently doing it is by referencing the stage instance linked to ClassB and then using the dot syntax to access ClassB instance variables, and this works only if the the accessed variables are public or internal, depending on what package ClassC is part of. I would like to know if there's a better, cleaner way to accomplish this.

I'm having this problem: I have an external fla (Dawn.as) and I want to instantiate the class from the external file into the main swf timeline, but when I try doing that I get an error:
ActionScript Code:
TypeError: Error #1009: Cannot access a property or method of a null object reference.
at Code::Chapter/initialise()

've tried calling constructor class from my main.fla, and it just doesn't work. The error when I try to instantiate the constructor is that it needs an argument... and since the class extends a Sprite.

this._images = new Array();

...and after many days of being tested by this problem I have narrowed the location of my problem down to what can be seen up in the following.
Code:
for (a=0; a<4; a++){
for (b=0; b<4; b++){
var z:Number = ((a*4)+b);
_root.attachMovie("Light", ("L" + z), _root.getNextHightestDepth(), {_x:(a*45), _y:(b*45)});
}
}
For some reason, that loop will only attach one copy of my "Light" movie. I cannot seem to figure out why more are not added. I am putting that code on the first frame of my movie. There is nothing else in my project yet.

I have a symbol named picHolder. In symbol properties under linkage, I chose "Export for ActionScript" and "Export in frame 1" and gave it a class name of picHolder.Normally, to instantiate a new instance, I'd say:
Code:
var tempPic:picHolder = new picHolder();
and I'd go about my way.

View 4 RepliesWe used to write our UnitTests with FlexUnit and we were just testing our model. Now we want to test the view too. Before i run my tests i create an instance of my view and my model to test the stuff. When i try to access the view i get a null pointer exception. If i add the view to the displaylist it somehow works - even if i remove it from the list right after adding.it looks something like this:
var myView: MyView = new myView();
//myView.initialize(); will throw error

I'm looking to load external .swfs that have graphical assets in them which are all 'exported for actionscript', and instantiate those assets in a .swf packaged for iOS. I'm using the adt command line packager to create the .ipa file. I'm including the .swf files while packaging. The .swf files seem to load correctly, and give me no errors, but when the Loader for each .swf's bytesLoaded equals bytesTotal the content property remains null.The program works perfectly when I package the .ipa using the -target ipa-test-interpreter flag, but not when I use the -target ipa-test.
I'm assuming the problem is that iOS doesn't allow Flex developers to load external .swf files that contain actionscript, and the 'export for actionscript' in the external .swf files counts as actionscript for the purposes of Apple's security policies. I'm looking for confirmation as to whether or not this is the problem.When using adt to package .ipa files, does iOS block external .swf files that have library assets that have been 'exported for actionscript'?

How do you instantiate an MC that resides in an external swf library?
So for instance loading "shape.swf" and instantiating "square_mc" from it's library onto the parent stage.
i've been struggling with one problem for weeks, and i've just found what i think is a possible cause (or at least a contributing factor)
This line:
Code:
var totalOffset:Point = rangedWeaponData.totalOffset;
What i thought it was doing is creating a copy of a static variable, for me to manipulate. However my debugging seems to show so far that it's actually creating a reference, and my subsequent manipulation of that is also manipulating the base variable it references.
Code:
var totalOffset:Point = new Point(rangedWeaponData.totalOffset);
Is there any difference in performance, or instantiation speed, between the two? Will anything be different in the instantiation of the MyClass object?
public class MyClass
{
private var _myObject:SomeClass = new SomeClass();

I've noticed that using large jpg;'s that are highly compressed take a lot of time to appear as a mc on stage after calling " new mcname();"
I have doubled my background from 1500X900 to 3000X1800. I use a movieclip in library containing the .jpg source image. Creating the larger one takes about 5 times longer to appear. Kicking my levels start from about 4 seconds to a 20 second wait.

I'm making a vertical (constantly) scrolling shooter & am trying to instantiate objects based on a timer. For example: At 30 seconds, place a building @ x, y.

1.) How can I instantiate the bricks without taking such a big performance hit?
a.) currently, I�m instantiate the bricks that make a column one at a time. I tried doing this with a repeater which did work but I could not get the animation to work on each individual brick. The animation would only work across the entire column.
2.) How can I get the UIComponent that contains the brick columns to align itself to the vertical bottom 10 pixels above the box along the bottom with the slider?
a.) I'm currently adding a UIComponent to the stage dynamically and then keeping a reference to that UIComponenet, I am adding my bricks.
3.) How can I improve the animation?
a.) Most of my research has suggested the only way to animate a sprite is to use a Timer() or connect to the onEnterFrame event.
