ActionScript 3.0 :: Add To Stage Only Once Initial Changes To Properties Are Done?
May 12, 2010
If I have a textfield instanciated from the document class with a base .string set as for example "4444" and BEFORE adding it to stage, I change the .string value to say "1234", when I test the swf, I can see the 4444 for a very short time changing for the 1234.I didn't change the value after adding to stage so I don't get why the display number is changed after being added to display.How to force it to add to stage (display itself) only once the initial changes to his properties are done?
I can't seem to find a way to get more than the initial set of 4 stage3Ds provided by flash. I have tried instantiating a new one using it's constructor and then adding it to the stage by simply pushing it to the list stage.stage3Ds.push(new Stage3D());
but this doesn't seem to be working as my eventListener for the Event.CONTEXT3D_CREATE is never called (it is if I use one of the default Stage3Ds. workaround or a way to accomplish this?
I have some code that adds a child using addChild(dragsquare); dragsquare is what I used as the class for a movieclip, mcsquare.
Everytime a child is added to the stage, it is called: ObjectX The "X" increments everytime a new object is added using ++objNum.
E.g:
Object1 Object2 Object3
etc...
When the child is added to the stage, it can be dragged, resized, rotated, etc...
I have used this code so when someone clicks the "save" button it loops through all objects on stage (increasing the last number by 1 to get the next object) and finding their properties. Here is the code I have used.
ActionScript Code:
Code: save.addEventListener(MouseEvent.MOUSE_UP, saveObjects); function saveObjects(event:MouseEvent):void { for (var i:uint=0; i<numChildren-23; i++) {
[Code]....
23 children already exist on stage so I have to minus that number to get whatever is added on stage by the user.
However, scaleX is getting the childs ORIGINAL properties and not its current stage properties (where it has been resized, rotated etc..) and only returns a 1 for scaleX. How would I make it track the properties it has on stage?
or if i'm using Flash Professional, i can simply set these properties for the document in the UI.
while the Stage class offers the ability to set a frameRate and override width and height thru properties in actionscript, why is it not possible to set the background color of the stage the same way?
Stage doesn't have a property (public or otherwise) for background color. can anyone explain why that is? it seems strange to me but i'm assuming there is a good reason rather than this simply being a oversight.
I have an object on my stage, called obj.I also have a class called "Physics" which contains a bunch of methods for physics, such as inertia, gravity, and bouncing off walls. In order to do some of these,I need access to the stage.stageWidth and stageHeight properties.My code is as follows:
public function wallBounce(obj) { this.stageRef = stageRef[code]...
This is supposed to check if the object's x value is greater than the stageWidth or less than 0. When I run this code it says:
TypeError: Error #1009: Cannot access a property or method of a null object reference.
I am a semi-newbie programmer who is completely self-taught and have no clue what is causing this. I spent a bit googling it, and I think it has something to do with scopes,.
If I have a swf that's being loaded into other peoples' swfs (which I have no control over) is there any way I can get properties from the stage (such as height, width, fullScreenHeight, etc.) or does this have to be exposed by the loading swf?
I am using this code to iterate through the contents of a movieclip which contains instances of "alien2" - my alien. I have each alien in a movieclip called squadron1. They all have their own layer and follow a motion path to recreate the attack sequence in Galaga. I can add action script to them by right clicking on them, but when I do this test below I can't call any MovieClip methods on them. It is my intention to add a function to each one via code to make it detect bullets, look for the player etc, but at the moment all I can do is add the code to each one individually on the stage.
Code: var target; for(var item in _root){ if(_root[item] instanceof MovieClip ){ target = _root[item]; [Code] .....
I am trying to access a property that belongs to the stage, from a class. For example, let's say I add a textfield with an instance name of "magic_txt" on the stage. In the Document Class, I am able to access magic_txt and update the field like so:
magic_txt.text = "Magic Text"
However, since I would like to work in classes, I am having a difficult time figuring out how to access the property "magic_txt.text" from a class. I know I need a reference, but I am unsure how to set this reference.
I am coming from a strong background in Visual Basic, and in Visual Basic, the way to access a form property is to call the form name (dot) object. In actionscript, it doesn't seem to be as simple.
is there a way to override a MovieClip's parent and stage properties? In a custom class extending the MovieClip class we can override the get parent() and get stage() methods. But is there a way to do it to existing MovieClip?
I mean I have an external swf content (loaded) and assigned to a movieClip. But now, how can I assign the loaded MovieClip to my custom class, so that it "doesn't see" the parent and stage properties?
Or can I override functions of existing classes? Sth like:
override public function myMovieClip["get parent"]():DisplayObjectContainer { ... }
I just need to prevent a loaded MovieClip from having access to the main movie's stage.
How do I access Stage Class properties in Custom Class? Class: package { import Main; import flash.events.*; import flash.display.Sprite; import flash.display.Stage; public class Run extends Sprite { [Code] ....
Output: TypeError: Error #1009: Cannot access a property or method of a null object reference.
I have made a very simple swf in which I have a MovieClip which I have rotated on the stage. When I try to access this rotationX and rotationY properties of this clip using the constructor of the class assigned to this MovieClip they are coming back as 0 even though they shouldn't be. If I put an on rollover event of the MovieClip and trace out these properties here I get the correct values.
1) In my program, I am wanting to create a function that would take in the height and width of a loader object, compare them to the stage dimensions, and then scale the object in question before it is added to the display list. However, I have several different types of classes that I want to make use of this functionality. So what would be better, to create a NEW class that would have to be created each time a resize needed to occur, and is imported by all needed classes, or just have a function within each already existing object and copy that function to every class's scope that needs it? Would this be resolved by placing the function in question inside of the default package?
2) When accessing stage properties, are they a global or a relative scope? i.e.[code]would those two statements produce the same value regardless of whether they were in the default package or inside of 1300 classes? Or is the stage scope relative to some degree?
Just been playing around with the tutorials, on the Set properties/Get properties. Everything is all cool, except the "instance name" aspect. I dnt really understand that too well. Is it possible to change an Mc Name dynamically? If you look at my FLA when you hit the top left red button you will get a trace of the mcName as "square". Now if you input a new mc Name on the right hand side, you will see it change on the left hand side. But i want to know why it doesnt remain as the new mc Name, it still goes back to square.
I forgot to put it in the title so I'll just place it here; I am using AS 2.0. I know that there are other ways to accomplish the goal that am after, but I was wondering if anyone knows of a way to access the properties of an object's properties?
Here is the code that I thought of, even though it doesn't work
var a:Object = new Object(); a.bproperty = 0; //lowerlevel properties a.cproperty = 1; // lowerlevel properties
[Code].....
This really just boils down to how I am organizing the code(I have ideas on what do next, and i am 99% sure that I can get them to work), and if there is a way to dynamically access the properties of the objects properties, It will save me from creating yet another large block of code for my project.

I have developed some code whereby the positions of objects on the screen are represented by two values and I store all this data in three arrays like so:
Code: objectName = new Array('flower','boxy','fleawhale','vampirefish','littlefishies'); initialXoffset = new Array('24','83','14','50','40'); initialYoffset = new Array('100,-170','10,50','20,100','50','-200');
i have a comboBox that has a defined fontSize for the choices inside which is 10, (myComboBox.fontSize = 10. How can i change the initial value, label I'm guessing, to be a fontSize of 10 as well?
I'm using FLVPlayback to display a flv in a swf embedded in html. Autoplay = false, wmode = transparent / windowless. I've got it working (not yet set up the way I'd like, but that's another issue), but the way the flv displays when the page loads is a problem. The controls skin is clearly visible, but the movie frame displays as a white box on a white page, barely visible except for a faint outline.
I guess the white screen simply represents the first frame of the flv. Ideally I'd like to see either a black box or the first frame with meaningful content. Is there any way (say with ActionScript) to advance and stop the flv to a particular frame? Or is there some other way to not see a white box here?
See attached screen grab detail. If it helps, here's my html.
I would like to add a code that would add an initial call to the function myFunction, but because it is listening for a MouseEvent, it has to wait until a MouseEvent happens (CLICK)
I thought that I could add a parameter to a function call like this:
Code: myFunction(e:Event, buttons[0]); but that did not work.
I've set-up a menu using the actionscript below tracking bt up / down states (credit - thanx Barn:[URL]..
But I'd like to adapt the script to have the home button (mvcBtn0) initially set by default to the down state - and then revert to the up state as soon as another button is pressed.
I've tried various adaptions sending the clip to down state on load and then the up state once another button is clicked - but none are working.
...How do you do this? I'm gunning for <65 kb and need to figure out if my published swf will meet this goal. Is there a window or something (maybe a 3rd party tool) to let me know what the initial download size of my swf is?
I have a few inputFields on the stage and I would like to give them an initial value, I know I can put that value directly to the inputField the problem is that this value may change depending on some conditions. how to give an initial value to a inputTextField?
Okay maybe its because I've been working on this all day and can't think straight any longer but this seems like it should be really obvious and I'm getting frustrated that I can't think of how to do it.I have a movie clip sitting just off stage. When the file is first launched I want to record the x position of this movie clip in a variables, say startX. When a button is pressed (and there are several of these) I am using Voetsoejba's easing code (brilliant) twice, once to move an MC just in the x direction (easeX):(on the main timeline, whre movetxt and content are the two MCs)
