ActionScript 3.0 :: Efficiently Creating/populating A 20x20 Cell Matrix
Dec 9, 2009
I have a 20x20 matrix set up in Excel that I'd like to recreate in Flash. Essentially the values are either 0 or a calculated formula of -Fo or 1+2(Fo).
My question is with a matrix of this size, is there an efficient way to create and populate it besides hard coding the address for each data cell? Can I make this using a loop?
I've attached a snippet of what the Excel sheet looks like. Notice the data trend.
I suppose this is an easy question but I can't seem to get it to work. How does one create and populate a 2d array in flash? I am first defining the array with:
[Code]....
that this code exists in another for loop which loops i also please assume that 5 is my total list of entries in the xml file i simplified my code for posting. i just want to know what the proper synax is for populating this 2d array. also how do i access it? array [i,c]? right now whats happening is the array does fill up but only with the last values.
I'm really new to flash, with my background mainly in C++ and Java. But what I'm wanting to do is create a 5x5 button matrix to make a game.I've tried using the visual style of drawing the button and what not, but I really don't like it. I'd like to have like an array of button of object where I can track things like click count for each object. Is this possible with action script?
I have an application that reads in an external XML file, parses out the pieces, displays them, and then allows the user to edit them. I would like to have a save button that the user can press that would save any changes to a new XML document somewhere on the server (any file location that I specify).I've been looking around online, and can't find any examples... all I can find is that this ability wasn't available until flash v.10.Another option i was considering was to create an XML variable, create it's value, and then somehow forward the user to a coldfusion page where I could then create a file.
I want to create a bunch of squares appear in a grid-like fashion but not row by row. I'd like more of a diagonal effect.
Here's the code I have so far:
[code]...
So this sort of works in the sense of it creates a vertical row and a horizontal row. But I need it to actually kind of 'wipe' diagonally across the page.
I am working on a project where I need an interactive matrix of 500x500 clickable elements. I thought this would be an easy task in actionscript3 but boy was I wrong. I was able to create a matrix where each element was a Sprite object with attached Mouse click event. But here the performance problems begin. FlashPlayer10 can handle up to 100x100 matrix, but when I increase my matrix I start getting script timeout in browser player... Here is how my "unfinished" matrix looks like.So how should I approach this problem? I was hoping flash will be able to handle so many elements, but I guess I was wrong. I want to have a pan control to pan around for objects off screen and of course zoom in/out control.It's true I'm not very professional in Flahs and actionscript but a friend who is told me this would be no problem implementing in AS3? I need this in flash as the thing needs to be hosted on website.

Has anyone here ever developed a function (or general library of relevant functions) that will allow one to find the inverse of a matrix? I've searched the forum archives, as well as the internet more generally, but haven't found anything. If anyone has some leads, I hope you'll pass them along.
If I don't hear anything within the next few days, I might try to develop something on my own, but I'd hate to do so if someone has already done the dirty work.
A solution to this problem would be very useful for 3-D work or anyone doing mathematical programming more generally.
I am building a Flex application using Pure MVC pattern and Zend framework for calling php code on the server. I need to sync some data with my server which is using MySQL as the database. And there are 5 such tables I need to sync. So I call these php functions at regular intervals from Flex and use long polling on php side. The client side code for my subjects lies in 5 different proxies.
Should I send 5 separate requests from each proxy to call the php code which is lying in separate classes. Or should I build a separate proxy to send 1 request from 1 php file and then distribute this data among different proxies on the client side. Which one will be more effecient? Mathematics shows using separate proxies and php classes allow more number of users to be accomodated on the server.Can I write 1 SQL command to fetch data from all 5 tables given they cant be joined on any column?
The game that I'm currently making has many bitmaps, for the sheets for various things. Is there a way that I can store these efficiently so my flash file is huge?
I have 9 movieclips in the stage. When I click a movieclip I load an image to it. The below code does this with one movieclip named o1. I feel stupid to just copypaste the code nine times for o1, o2, o3.. etc. What would be more efficient way of doing this?
I have one fla with a lot of library symbols. At some time part of these symbols were copied to another fla, and updated. Rather than copying the modified symbols back to the original movie, I want to use authortime sharing. So I click on one symbol at a time in the original fla, click source, scroll to the other file in the file chooser, wait for the library to open, scroll to an identically named clip inside an identically named folder ....the source is shown as a full path - is there a way to make it relative (in fact the two fla files reside in the same folder)?
Longtime Flash Pro, Flex, and AIR developer, Dmitriy Yukhanov, has written a new article for the Dev Center listing over 60 tips for efficient use of Flash Pro. Categories include: Improving performance Optimizing file size of project assets Developing Flash projects more elegantly Making project files easier to update Most of the tips are illustrated and quite easy to understand. This is one of the most comprehensive articles on this topic that I have seen.
I have overcome a problem, but my solution seems really inefficient and clunky. Please consider this problem:
I have an array collection with articles in.
This array collection is filtered to a currently selected article category.
There is a cursor bound to a view that shows the current article. When a category is deleted I need to delete orphened articles, I can't use the cursor or collection without affecting the views as they are bound.
ActionScript Code: var request:URLRequest = new URLRequest(XMLslides.item.thumbnail[i]); var tloader:Loader = new Loader();[code].....
Works fine (it's in a for loop, ...after the main XML object is loaded)... but this:
ActionScript Code: var request:URLRequest = new URLRequest(XMLslides.item.thumbnail[i]); var tloader:Loader = new Loader();[code].....
Causes those thumbnails to be attached to the masked buttons, but not the new ones.Is there a way to do this without creating another loader object? I want to keep it efficient.
I've created a game engine using bitmaps and box2D, the floors for the game engine is made out of a number of lines which then has a bitmap fill applied to it, then it adds a little bit of grass on top of these floors....Here's a quick video to show you what I'm talking about:http:[url].....
This all works fine on my main computer, but when I move over to my netbook, I struggle to get 10fps... Because of this I am now looking for as many ways as possible to improve the efficiency of my code. So far what I've done that appears to of had some positive effect is:
- Use bitmapCaching on layers where it's appropriate to do so.
- Use scrollRect to scroll on only the necessary part of each of the layers.
However I'm still having big problems when it comes to scrolling the terrain on my netbook - are there any ideas that anyone might have which might be able to speed up the game slightly?
I have a browser-deployed Flash app (not an AIR app with access to SQLConnection) and it fetches JSON results from a remote server via HTTPService. I need to extract subsets from the returned resultset, an array of objects, efficiently. Mutltiple calls through the cloud to the back-end won't do. It all has to happen client-side.Is there any collection class in Flex ActionScript that can sort an array of objects by one of the properties the objects all have in common, like the Array sortOn method, and then also provides a binary search method can extract a subset of objects from the sorted version of the array without visiting every item in the array and comparing?if I have an array of objects and each object had a zip property and a name property, I'd like to be able to extract all objects with zip = 10015 from the a copy of the original array where the copy has been sorted on zip.
I have an ArrayCollection of Objects. Each Object with three attributes:CustomerID, Income and DateMy goal is to chart this data for each customer (or a couple together) in a Income by Date LineChart display. Selection of customers is done with ArrayCollection filters.Data is fetched from an SQL database, however, each customer has some data points missing.f there was zero income on August 8, 2010 there will be no entry for that.Charting the ArrayCollection as is, is misleading because there is no indication of the missing data points.One way to solve this is to artificially add zero points for the missing dates for each customer. However, this would explode the data set (and impact performance).
I have brought in an XML document into Flash (AS3), and can pull any string that I need to into the output window. That is all fine and good - but what I need to do is set var values to be used later.
This outputs what I want, but the problem is: if I try and trace newVar our assign another variable the value of newVar outside of the processXML function, it isnt there.
how to get this to work, but I've finally gotten Loadvars working dynamically. However, now I need to take the "avatar" variable and use it to populate a list component. I keep reading dozens of different ways to do it - turn your variable into an array in Flash, etc. What is the best method?
So I have a list box on stage with the instance name "lb" I'm trying to get some text from my xml list into this list box? In this case the @TITLE data.
I'm able to trace the data from the xml file into the output window, but I can't figure how to display that text in the list box.
Why is this not populationg the fiedls with images? The XML is well formatted (I tested)myThumb has a Loader called myPicMC, where the pics are supposed to load. I supposed the proble is with the code in bold blue. [code]
I have main-swf that loads external swf. I made a combobox where user can choose another external swf and main-swf loads that after user have made selection. Everything works fine as long as code combobox labels and datas directly to the actionscript. When I tried to populate combobox with extrernal XML-file, it didnt work.[code]So, what I would like to do is get rid of that "varlehtivalikko: Array = new Array" where combobox data and label info has been stored and load that info externaly from my XML..
I am creating a RSS Feed application based on a data, and I have the following:
I have an ArrayCollection that is pre-populated with data. I am sorting through the ArrayCollection, get 1 piece of data (condition), and need to connect to an RSS feed which returns me the title, and I set my ArrayCollection in correspondence to condition -> title.
public function updateArrayList(list:ArrayCollection):ArrayCollection { trace(list); for(var i:int = 0; i < list.length; i++) { //Alert.show(list.getItemAt(i).condition);
I have have a problem loading and accessing data from a value object in my new project.. I load an xml file via a service, which contains title and locations of asset files, I need to be able to access the location of an asset file by specifying the title and retrieiving it from a value object.. I'm using the Robotlegs framework, here's an example of the xml:-
I'm trying to wrap my brain around getting data into my project in a way that I can use.. I want to use MySQL & PHP my Flashbuilder app and I'm not populating a datagrid so......
For simplicities sake, In my database table I have 3 columns "ID, Title & Content". I want to use this to populate the different states in my flashbuilder project.
Normally in a web page I could say in the sql statement "SELECT * FROM table WHERE ID = 1" to get the first row of info and I could put my Title and Content where I want them on my page I can change the query to "SELECT * FROM table WHERE ID = 2" to populate page 2 to get it's title and content.
In flashbuilder it all on the same page and I'm not understanding how to populate a singular text field for a title or content area with a single field from the database.
where the component before / represents parent and the children of the corresponding parent are separated by , Can anyone provide me the logic to create a array collection for this hierarchy to set as dataprovider to my tree.
