AS3 :: Flash - Only Allow Access To Certain Properties On DisplayObject?
Jun 16, 2011
I have a getter within a class which is used to make my property skin:DisplayObject read-only. This class also has a property body:AvBody which is used to define the x y width height etc of the object, which in turn positions the skin.
What I want to do is disable access to the properties x and y on skin unless accessed from within the internal namespace (where AvBody is also located) Is this possible?
Note: I can't make skin any type other than DisplayObject (I can't even make skin a class that extends DisplayObject because it creates issues with library symbols).
In regards to as3 project: Is there a way to inherit the properties of a given DisplayObject? I am looking for a single method that will grab something like the x, y, width, height, color, etc. Whatever is involved in the common classes between the two display objects.
Edit:
I don't think I was clear enough... Let me give an example of the type of functionality I am looking for.
var sp1:Sprite = new Sprite(); sp1.x = 30; sp1.y = 30; sp1.width = 500; sp1.height = 30; var tf1:TextField = new TextField(); tf1.inheritTransform(sp1);
So, in this case I know that the method 'inheritTransform()' doesn't exist, but I am wondering if there is something similar. Or maybe I am missing the point of extending a class in some way? I don't see how the two would relate in such a case.
I'm trying to figure out a way to use a loop to cycle through all the properties of a DisplayObject and class extended off of it, like in using a for(... in ...) loop on Objects.
I am currently working on a shooting game, its also a trial for me to use Classes and Packages.My set up is the stage holds the player, the script then adds 2 movieclips, enemy holder and a bullet holder. The bullet is then added to the bullet holder.
I have 2 movieclips. One is a fairy flying up the stage. The other movieclip is a magic dust, which is originally designed to generate magic dust with onMouseMove event, based on the mouse's x & y. I want to change the the magic dust movieclip so it will generate magic dust following the fairy's movement.[code]...
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 flash CS3 with ActionScript 3.0. Suppose, I created a button component and a Combo-box component. Hence, SWF file consists of a Button and a Combo-box component. Now, my requirement is, How to access the instances and properties of these components(Button and Combo-box), so that I can create HTML webpages depending upon the Combo-box selection and the Button click events occurred on flash components? Here, we need to pass/send the flash components' instances to HTML. How can we do it? All I want is to access the flash components in HTML.
Given this:public namespace foo;foo var bar:String = "baz";We can access the property "bar" like so:[code]It gives me the following error: ReferenceError: Error #1069: Property foo::bar not found on MyClass and there is no default value.On further inspection of the foo namespace I can see (in the debugger) that the URI is in the format {package}:{type}/{name}. If I try to replicate this by doing the following:[code]Does anyone know if it is possible to get access to namespaced members like this? I don't have compile time access to the namespace, but I can look up it's uri (and prefix) dynamically at run time.
I would like to be able to quickly check if a given DisplayObject is a descendant (not in the inheritance sense - ie. child, grandchild, great-grandchild, great-great-grandchild, etc.) of another DisplayObject. There doesn't seem to be a native way to do this and I can only think of two ways to achieve it: Create the mother of all nested loops. Seems a bit, I dunno, wrong? Dispatch a bubbling event at the 'child' and check if the potential 'parent' receives it.
My aim is to access the FileReference class Flash Player 10 properties,methods and Events using CS3 instead of CS4.For load() ,save() methods needs runtime version of Flash Player 10.I need to include the flash player 10 in CS3 publish settings Version.Otherwise you can suggest how i can able to access the FileReference class new properties and methods without CS4.
I will be choosing which mask to use based on users selection of puzzle piece.When I try to use traingular mask by adding puzzle.gotoAndStop(2) the swf just flickers. Thought the holder_mc and mask_mc are exactly of same dimension one comes below lower than other though I have not altered the position of the clips within a puzzle piece.If you want to take a look at my fla here it is https:[url]....How to go to a specific frame 2. Why is position of two clips inside the piece changing
So I have a movie clip associated with an external class in the linkage dialog. I put that movie clip on the stage. I have another external class that contains some code (not for the movie clip but for the stage). When I access the custom properties of the class in the actual flash file (not the external code) everything works fine.For example.myMovieClip.explodeTheCode = true;works in the main movie. However, it doesn't work in the external flash file when I have a reference to that movie clip.myRefToCustomMovieclip.explodeTheCode = true fails!It throws an error. In java, I'd just import the custom class the movie clip is linked to and then I can call all the extra custom methods on the movie clip in the external class I want. However, this does nothing. I still can't access any properties.So my question is, how do I access the custom features of a movie clip (that is linked to a custom class) from an external code file. It works in the movie, but not in the external source code.
This is a problem that's best explained in code. I don't see how active_button.upState, which I know is a TextField (see trace statements), mysteriously turns into a DisplayObject when I try to access the textColor property. I've included the error messages below for reference. Also, why is it that when I have an object that I know is a SimpleButton (again, see traces) I need to cast it to SimpleButton in order to store it in a var? That doesn't make any sense to me.
I have a movieclip in the library with the linkage name:BackgroundClip, so in the constructor I create it, add it to the display list and can even access and modify its properties, which I tested with the x position. Now what im having issues with is getting the stage resize listener to adjust the BackgroundClip instance, bg, to the stages width and height. In the clip is an image, so if someone has a better way of using classes to create full screen liquid gui im all ears![code]
I have a calendar where each day is a movie clip called 'day'.I use calendar1 movie clip as a parent to day, which means day is inserted into calendar1 using this line..the issue is that I can't access any of the checkbox properties, but all of the text properties as illustrated below.[code]
I need access to the properties of a file I load on the next line. Specifically, trying to pull the _height and _width off of it.
I think it's being bungled up because it's inside a function running two (nested) for statements. Let me post up the code for you geniuses[code]...
The width traces fine in the onLoadInit, but only AFTER the function that is creating and positioning the movieclips is finished running. They are nested in something of a complicated heirarchy so to save the widths in another array and then try to move them all later would be bonkers.
Let me just start by saying this forum is awesome, over the past 3 years I've found nearly all of the answers to my AS questions without posting once... That streak ends today.I'm building a site where the client is going to be able to upload various backgrounds which load depending on which tab they click on.
The class is BigBackground.as. It does the loading of the backgrounds, and then in the .fla I would like to manipulate these "BigBackgrounds" starting with the width. However, even though the width traces correctly from BigBackground.as, the width traces to 0 from the .fla file. I can access width from the class, but how can I access the width & height from the .fla?[code]...
I'm new to as3 and I was trying to make my own slider for a while until I found the slider component. The slider component is so perfect for what I want to accomplish. But the size of the little graphics is ridiculous. If you click on the line that the slider knob is on top of the knob will snap to where you click. This is great but with only 3 pixels of height to click on it's pretty much useless. I tried going into the slider movie clip and altering the individual graphics but when I run the program the sizes are back to their teenie tiny size.
In my controls I have keydown events that control my hero. As of right now, I am trying to rotate my hero but he refuses to turn . Below is my Hero Class, my control class, and gameobject class. pretty much all the classes associate with the controls class.
Main movieclip onstage is : design_mc. Within it is a movieclip already in place onstage with an instance name clipart_mc.also loading a ListBox to the stage and each time a selection is made from listbox myLoader9 is used to load selected .swf intodesign_mc.clipArt_mc.Now within each of the .swf files loaded into design_mc.clipArt_mc there is a mc ike to color transform called color_mc.So now the listbox is onstage and I make a selection that places heart.swf inside of design_mc.clipArt_mc. I want to access heart.swf so I did this:
var child:DisplayObject = myLoader9.content.contentLoaderInfo.content.color_mc; var colorTrans3:ColorTransform = new ColorTransform(); var trans3:Transform = new Transform(child);
