I have a problem , how position a plane in surface of sphere.
i am developing an application where client can add his photos to appear on a sphere or ball or coffee cup and able to save them and give it for printing using flex. like itasveer.com site. i tried to use away3D but if the image is small it is stretched and added to sphere. i dont want it to strech instead the original image shud appear on the sphere. if it is added to cup it shud cover only the circular part it shud not add this to top and bottom.

And I want to take plane 3D coordinates (x,y,z) expecially z-coordinate. I try below code. But it doesnt work correctly. Mouse and plane are not be same coordinates on screen. How I can do?

I'm developing using Eclipse Indigo, Flex 4.5.1, Papervision 3D 2.0.883. Basically what I'm trying to do is get this papervision3D/Flex example to compile so I can use it for a movie viewer on my own site. I've had to make a bunch of changes to get it to work with Papervision 3D 2.0, so that may be part of the problem. My application spits out the following complaint when I run it in Flash Debugger:
TypeError: Error #1034: Type Coercion failed: cannot convert org.papervision3d.view::Viewport3D@2bf6df49 to mx.core.IUIComponent.

I am working on a game in which there are several Plane objects that the player can click. My main application class extends the BasicView class. I made this whole game as an ActionScript project and everything works fine when I run it as one.
Now I load this game in a Flex application. When added to the Flex application, it runs perfectly until I click somewhere at which point it throws the following error:

I am trying to create a bullet hole effect when you click the mouse down.I want a bullet hole to appear where you click the mouse and to stay there, and then when you have > 10 bullet holes on the stage i want to earliest ones to start to fade out.
Here is my code so far:
[AS]
onClipEvent (mouseDown) {
i++;
this.duplicateMovieClip("BulletHole"+i, i+1);
[code]...
However this just duplicates the movie clip and then when you click again it disapears straight away.
I've just recently learned the PureMVC framework, and am a little confused as to the coupling between Proxy and Mediator objects. The links on this page connect to some documents describing the framework. (Please note, the links on the aforementioned page open PDFs.)
The diagrams and examples of PureMVC I've examined often show a direct coupling between a Mediator and Proxy. When the proxy's state is updated, rather than sending a new Notification, the Mediator (which retrieves a reference to the Proxy from the Facade) has its state updated.
This certainly seems to simplify the logic of the code, but it also directly couples two seemingly disparate components together. To my understanding, a Mediator's purpose is to translate Events from a view into PureMVC Notifications. Proxies are meant to perform some function to gather data and relay it back to the view. These two components seem to exist in different layers of the application, and perhaps shouldn't necessarily be coupled together.
Wouldn't it make more sense to have the Proxy objects send their own Notifications when their state updates, which are forwarded to the interested Mediator by the Facade?
I use AS3's drawing api to draw filled shapes, but when they overlap, instead of filling the overlapped area, it becomes clear again, with no fill.
My question is, how can i get rid of this behavior, i need to just fill everything, is there a way to somehow "flatten" the shapes?
How would I go about cutting a transparent hole into a Graphic and leaving a stroke around the hole I just made (similar to if I had used the Eraser tool on the Flash canvas, minus the stroke)? My first instinct tells me to draw a circle over the spot I want to "cut out" with a stroke of an arbitrary width and an alpha-less fill, but if I were to click-and-drag this hole - or simply make another overlapping hole for that matter (again, as if I were using the Eraser tool), the stroke would definitely not appear the way I want it to. If anyone is familiar with how the terrain is blown away in the 2D Worms series, that is more or less what I am going for.
View 1 RepliesI'm going to write an application with the Air/Flex-Framework. I'm looking for Best Practise and general Design Patterns for designing software especially in Air/Flex. I have experience with this framework but never had the pleasure to write a piece of software from scratch.
For instance: I stumbled across lots of software written in Air/Flex with nearly infinity global vars Most of the software I saw was not object-oriented How can I pack the asynchronous method calls nicely?
I'm familiar with general design patterns by gamma. I'm looking more for advise in designing good quality software with Adobe Air/Flex.
I've got a continuous plane (2-D) containing polygonal obstacles. I am uniformly sampling the plane at discrete positions to create a uniform grid of points. The grid does not have points where obstacles lie (i.e. holes where ever an obstacle is) as shown in the image below.[url]...
View 1 RepliesI need draw rectangle with two circle holes inside. The problem is in circles interception. I want them to join together and cut from background, but they seems to be XORed:
At first I tried drawRect and DrawCircle:
graphics.beginFill(0, 0.5);
graphics.drawRect(0, 0, width, height);
graphics.drawCircle(width/2, height/2, 50);
[Code].....
here getCirclePath returns object with points to draw polygon which looks like circle. Also I tried different combinations of GraphicsPathWinding constants, but no luck.
how to draw two intersecting circle holes in graphics?
I have only worked on web apps for my whole career.I'm starting a new desktop (Adobe AIR) app project but I found myself having difficulties with:
stuck with thinking about overall UI design in the traditional page model
not sure how to handle the navigation part in the UI
not taking advantage of states
deciding what should be implemented on client vs server side, (or on both?).
Flex has the notion of lazily loading data. It has a class named ItemPendingError which allows developers to handle it when an attempt is made to access data that is not yet available aka "pending".However, looking at the documentation it's clear you have to add try/catch blocks around your code wherever you have code that might cause an IPE (ItemPendingError) to occur.I'm curious if anyone knows why it works this way. I'm not sure what the best solution might be, but having to willy-nilly add in try/catch blocks to catch the error and then register a Responder with it feels bad and not very clean. And the fact that you sort of have to exercise your application to make sure you've caught all the possible places where the error might occur is also lame.Is there some other way or better approach that I haven't seen/heard of?
View 3 RepliesI now need to design a chemistry periodic table. I will have a set of few elements that have been chosen by the user,and that should be reflected on the periodic table by making these few elements clickable.So when the user clicks on these few elements,corresponding explanation text will pop up on the text area outside the periodic table.Making all the elements of the periodic table buttons,so only the buttons that are within the set are enabled(clickable),while others are disabled.Embedding a static periodic table picture,and do things there(don't know exactly how yet).

I'm working with an application which was originally designed to make heavy use of static-variables and functions to impose singleton-style access to objects. I've been utilizing Parsley to break apart some of the coupling in this project, and I'd like to start chiseling away at the use of static functions. I will explain the basic architecture first, and then I'll ask my questions. Within this application exists a static utility which sends/receives HTTP requests. When a component wishes to request data via HTTP, it invokes a static function in this class: Utility.fetchUrl(url, parameters, successHandler, errorHandler); This function calls another static function in a tracking component which monitors how long requests take, how many are sent, etc. The invocation looks very similar in the utility class:

View 3 RepliesWhen i try to open my mxml script in design mode i'm always getting following message "This Component is base on VBox, which is not a visual component. Switch to source mode to edit it"
View 1 RepliesI have mxml thingy, for example:
<mx:VBox id="isThisVBoxAwesomeOrWhat" width="500" height="500"
backgroundImage="@Embed('images/500x500.jpg')" verticalAlign="bottom"
includeInLayout="false"[cod
So, I have a Vbox names isThisVBoxAwesomeOrWhat that contains another VBox that containst two text fields.Now, further in the code I make a plane out of it so I can make a 3D object out of it, here is the snippet:[for i in totalPlanes]
...
var material:MovieMaterial = new MovieMaterial(isThisVBoxAwesomeOrWhat, true, true, true);
...
plane = new Plane(material, isThisVBoxAwesomeOrWhat.width, isThisVBoxAwesomeOrWhat.height, 10, 10);[code].....
So now I have my scene filled with planes made out of VBox composite as I wanted. I also have those planes in a linkedList, and what I would like to do now is to "SOMEHOW" access each individual VBox and it's composites for each individual plane.Something like this (obviously doesn't work! Just an example):
linkedList.node.data.VBox.VBox.Text[0]
so I could modify parameters on the fly. Or maybe I'm totally wrong on this and I should have as many Vbox'en as I have planes and id each individually. Whatever the case I can't figure out how to access children of the parent in this mxml example.
My embedded images show up in the Flex Builder Design Preview, but are not displayed when the application is run. The images have relative paths (/assets/images/...), and the application is run on the server (wamp). I've appended the path to the compiled location [URL] and tried to display a image in the browser, and the image exists, too. I've compiled it via FlashDevelop, Flex Builder, and Ant. I've deleted and remade the bin/bin-debug/release/bin-release files to no avail.

View 1 RepliesI have a very interesting challenge here for my Flex project development. I now have an experiment wizard which consists of three states.In the first state,the user selects the elements they are interested from the periodic table. When it comes to the second stage,now we have the elements that the user selected in the first state,and these elements are shown on a list A',the user can select an element from there. Also,I have an xml file that has the intensities and wavelengths for all the elements in the periodic table
