Flash :: Finding Correct Scope Of An Object For A Callback?
Dec 11, 2009
I'm working on writing a tweening class in as2 that has a callback variable and I can't seem to find a good way to get the scope without specifically passing in a scope variable as well. This tweening class needs to work in classes as well as on the timeline. Here's what my codes looks like right now.params.scope[ params.onComplete ]( params.onCompleteParams );params is an object passed into the class. This works but I don't want to have params.scope in there.
I have a video inside of another movieclip. When I go full screen, I scale up the outer movieclip to fit the screen. So that OuterMovieClip.width is equal to screenWidth etc. How do I maintain the aspect ratio on my video so it does not get distorted? Whats the proper math for that?
know if the index effect the scope of an object because I am creating a game and for some reason, I get an error like below
TypeError: Error #1009: Cannot access a property or method of a null object reference. at com.objects::Torret/updateObject() at com.objects::EngineApi/loop()
[Code].....
updateObject is the loop for all my objects. I have one centralized loop and in that loop it calls on an array of objects that have been placed on the stage. all of them containing the method updateObject. to update the status of the object. addGameChild() is a encapsulated addChild() , that not only adds the object to the stage, but places it in a array so it's updateObject() method can be called on. it is also used to make it easier for garbage collection.
In the first function homeL adds the 'restMenu' text field when it's called. In another function the hideTarget method is called and it checks to see if the objects name is "instance5" which is the name of homeL. Is there a way to link an objects name to the object because I get :
I have a menu MovieClip that has its buttons inside of it. I have the menu with a MousEvent.CLICK and trying to figure a way to register what you are clicking on.
i've been working on a problem for a while now, which involves targeting the closest movieClip in relation to the x y coords of the mouse, I've attached a nice little acompanying graphic.Each mc added to the stage has it's own sub-class (HotSpots) which uses Pythag to measure distance from mouse. At this stage i can determine the closest value from my Main class but can't figure out how to reference it back to the movieclip... hope this makes sense. Below are the two Classes.My Main Class which attachs the mcs, and monitors mouse movement and traces closest value.[code]
determine the base class of a Flash library object at runtime, using Actionscript? The toString method gives me the class of the object, but what I'd really like to determine is the superclass of the object. So, if I have an Actionscript class called "Fruit" and I created many different Fruit types in the Flash library ("Cherry", "Apple", etc.), is there a way in code I can determine that an "Apple" is a child of "Fruit"?
My web application pass a javascript object to flex application using addCallback function. when the flex application is in modal dialog in safari browser, the object in the flex application is null and when I open the flex application just in a new window, the object is passed correctly. But, I need the showmodaldialog to show the flex application.
The flex code: ExternalInterface.addCallback( "handleEvent", handleEvent ); override public function handleEvent( event:Object ):Object { Alert.show(String(event)); .....
I have a Debug class I've written, and I'd like to include a static trace() method in there, unfortunately I have no idea how to then access global / top level trace as effectively I've blocked it with the local static scope.[code]
Been doing some actionscript magic lately, done a nice interpolator class. The class, whenever an update occurs, calls a previously specified callback function. Normally, setting a variable of funCallback:Function and calling it works fine. However when I wanted to specify an *object's method* as the callback for the interpolator, it apparently called it as if it would be a static method.
And it isn't.What I need to do, simply speaking, is to be able to call an object's public method, having just th object's reference and function name, just like the second variant of setInterval does ( the one having "object, string" as the first two params, not "function").
I have a simple object defined by an object literal, and have a couple functions assigned to this object. Inside the functions, I try to access global variables, and it only gets undefined. The Flex debugger tells me the variables are just right up the scope tree.Yes, I know I can access Thing by using 'this', that doesn't solve my scope issue though.Project Flex Compiler Settings: Flex SDK 3.4, Require Flash Player 10.x.Example:
You will find enclosed a ".zip" file in wich there's a ".fla" file, a ".txt" file and 6 ".jpg" images. Frame 1 of the FLA only has a "Preload" class/constructor found on another site and works well. Frame 2 launches the graphic interface construction. The file "externalVar.txt" has one variable "maxVin" with a value of 6.
I would like to know WHY i can't acces this variable from outside of the loadVars object's scope (i would better say from outside of its ".onLoad" methode scope). In fact, when i trace my variable "maxVinNum" from outside of this function, flash player return "undefined". Even if i declare "maxVinNum" on the _root (_root.maxVinNum). For information, at the start of frame 2, i have let an instruction in comment: //var maxVinNum = 6; When we activate this instruction, then the variable is directely declared and everything works well. This test allow us to verify that scripts are not bugged. Here is the script of frame 2, some of you may understand quickly what's wrong :
I need to find an instance of a movieclip that is on my flash file. It is really big and uses a lot of memory. It says on the number of times used that there is one instance of the object on the flash file, but I can't find it. I thought I deleted them all but there must be one left. How do I go about finding it? It's a really large flash file with many layers, and I don't want to just delete the library file. Is there any way I can find where the object is placed in my file?
We have a client server architecture where a C++ server talks to Flash clients. I'm developing the server and would like to send through tcp an xy coord to simulate a button press where the receiving flash client would find the topmost visible object at that coord and send a mouse event to it such that we could simulate play without a human present. I'm told this is incredibly difficult, but it seems to me that there must be a way to do this. Am I off the mark? Or is there a mechanism in flash to iterate through all objects regardless of parent child relationships to find a visible button at an x, y coord and signal a press event?
I'm trying to write a plug-in for Flash CS5 that will display the "instances path" for a selected object. I'm trying to work with JSFL.I manged to get all selected objects using fl.getDocumentDOM().selection. I iterate over the array I get and look at the objects. I am able to get each of the objects' name. What I need to do is construct the "path" to that object (e.g., scene.scene.instance4.myText). Can anyone think of a way to do that? Is there a way to get the object that contains a certain object?
* Is it possible to create weak references to objects (like theventListener/EventDispatcher is able to do) so that if they are removed, you won't be stuck keeping a reference and taking up space to something that should be garbage collected?* Is there any way to find out how many active variables are referencing a certain object? This would be handy to actually create weak references, since, if you for example, have a static array containing all objects created in that class, you can do a regular check to see if there is only one remaining reference, and if so, you can safely remove it.
* Also, might there be any way to list the entire space (one big chunk of binary data, most likely) of every variable currently running in the program, all references, basically, what Flash is currently storing in RAM?I'm pretty sure that Flash (as crappy and lacking as it is in so many areas) does not have anything like any of these built in, but hopefully there is at least something.
there is a problem with IE browser it does not recognize object HTMLEmbedElement and not proceed for further execution . i have no choice because there is nothing to be updated in programming code
I'm building a class for a data grid that creates everything dynamically, and allows the user to add buttons to a cell easily. If the user defines a height for the dataGrid that's smaller than the content, the content is cropped and a scrollbar is added. Now here's where my problem occurs. Once the content is masked, and you then try to access the .height property of the dataGrid, it will return the height of the dataGrid + the masked content.So I added a get/set override function for the .height property. Now this works, but only if I'm constantly updating the height as I create my dataGrid. What I'm curious about, is how (when the properties aren't overridden) when you add a child to a MovieClip, it's .height property is updated automatically? For example if you have
ActionScript Code: var par:MovieClip = new MovieClip(); // each Cell is 20px tall. var cell1:Cell = new Cell(); var cell2:Cell = new Cell(); par.addChild(cell1); par.addChild(cell2); trace(par.height);
The .height will equal 40px. Is there a set somewhere inside addChild that updates the .height property, or is there a different way that they do it? Basically I'd like to override the .height property after a certain amount of the dataGrid is built (to compensate for the difference in masked content height), but since the override happens from the very beginning, I'd like to know if there's a better way of setting my MCs height rather than constantly setting it as I build the grid. Or better yet, is there a way to get the proper height of an object that contains masked content without having to override the height?
I'm getting a large JSON string and decoding it into an object, i'm looping through this object to create the interface. The problem is it seems to build the interface in a random order, is this because actionscript 3 loops through the properties of the object randomly?
Since Flashbuilder does not support WCF over https, I am considering to use weborb remoting as alternative, but not really sure how flash is going to know weborb location, if they are sitting on different servers. Looked at destination, source fields, but not really find a field called url in remoteObject in Flex.
I'm often finding a need to get a stage-relative position of objects in my game, which are often buried several layers deep as children of children of children, etc, often with differently scaled/moved/rotated parents. The position i want isn't quite relative to the stage, but a main holder object i have on it called lvlHolder (see code below). I wrote a function to deal with it that recurses up the display list, accounting for each object as it goes, to get a global position. It's worked so far, but one thing it doesn't account for is rotation. I'm finding a need for that now, and i'm not sure how to account for rotation of objects, to rotate offsets from them,
My function is below. how i should enhance it to accomodate for the rotation of each parent object? Also any tips on optimisation would be good, as i'm using this a LOT (roughly twice per frame, per object, for physics calculations) I'm also wondering, in similar situations i've seen something related to transform matrices used
I want to find out which type an object has. Therefore I thought of the 'switch' statement, but how would you do that? The following code does not work, but you will get the point of what I want to do.
Code: switch (object) { case is String: trace("string"); case is Array: trace("array"); [Code] ....
I have the code in one of my flex file used as labelFunction in a DataGrid.When I run the FlexPMD to do the code review, it generates an objection about the dynamic type object used in the following method signature and it suggests to use strongly type object.
public function getFormattedCreatedTime(item:Object, column:DataGridColumn):String { var value:Date=item[column.dataField]; return dateFormatter.format(value);[code]....
