Sep 27, 2009Essentially the code below does the following:
1) I've created a URLLoader object called loader to load an XML at [url]...
2) When the load is complete it triggers onLoaded which iterates through the feed and adds each item into an array called arrayVariable.
This array is designed so that for any particular i called in variableArray[i] it is possible to access things like the object's title, description, link to FLV and a thumbnail.
3) Once complete, it then fires up createMatrix which sets the initial x, y information and page references so that there is a grid once they've been added to the displayList.[code]...

ActionScript 2.0 :: Matrix Algebra And Matrix Inverse?
Apr 5, 2003Has 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.
Actionscript 3 :: Understand The Method Transition That Falls In The Matrix Class
Dec 31, 2009I am trying to understand the method transition that falls in the Matrix Class. I am using it to copy pieces of a bitMapData. But I need to better understand what transitions do. I have a tilesheet that has 3 images on it. all 30x30 pixels. the width of the total bitmap is 90pxs. The first tile is green, the second is brown, and the third is yellow. If I move over 30pxs using the matrix that transitions, instead of getting brown, I get yellow, if I move over 60px, I get brown. If I move -30 pixels, then the order is correct. I am confused on what is going on.

I've tried three different approaches, however only (3) seems to be showing up. I'm just curious why (1) or (2) doesn't work?
Also is there a better approach than (3)? Since at the moment it's been created on _root. I hope the box can only be accessible through the instance. Since I'd like to incorporate the whole idea of public, private, encapsulation, etc.

View 1 RepliesFlex :: Excel - Interactive Heat Map - Import Matrix
Nov 12, 2009I'm at a very basic level with Flex and with programming in general. I am working on a project where I have data in an Excel (.csv) format, it's a large Excel plot/matrix where each cell has a temperature number. I want to import this matrix into Flex somehow, or parse the data in Flex, so that this matrix turns into an interactive heat with colors corresponding to varying temperatures from blue (cold) to red (hot), and each spot on roll over shows the temperature number.
Should I use plot charts, or some other control? should I convert data into XML or import into a MySQL database, would that be easier for Flex? But then, again, the data is basically just a large matrix, there's no headers/ fields in a traditional database sense, just many cells each having a temperature number. how I can import the data into Flex and use it as data provider to plot the heat map?

Flex :: Animating A Transformation Based On Transform Matrix?
Oct 18, 2010I have a UI component that I wish to relocate and scale, but in a rather complex way. I've figured out the necessary transformations using the transform matrix, to which I applied several translate and scale operations. I can set the new transform matrix for this UI component to be the above calculated matrix, and the results are accurate; but I need to animate the transition. I can't use the Scale/Move effects alone because they aren't as powerful when it comes to calculating the necessary transformation as the matrices are.So how can I animate the transition of an object given a source and a target transform matrix?Figured it outUsing a tweener and its onUpdate event to reassign the matrix with each intermediate value:
var animMatrix : Matrix = gi.transform.matrix;
TweenMax.to(animMatrix, 1, {

View 2 RepliesActionscript :: Create And Use An External Class In Flex AIR App?
Mar 30, 2010I'm trying to build a Flex AIR app using Flex Builder 3, which I'm just getting started with. In Flash CS4, there's a text field in the authoring environment where you can specify a class that will become the "base" class - your class inherits from Sprite and then "becomes" the Stage at runtime. Is there a a way to do the same thing with Flex/AIR? Failing that, how to create and use an external class?
[Code]....
But that gives the error "A file found in a source-path must have an externally visible definition. If a definition in the file is meant to be externally visible, please put the definition in a package". I can't win! When I put my class in a package, it says I can't do that because it would be nested. When I don't, it says it needs to be in a package so it can be seen.

IDE :: Graphics Class - How To Get The Current Shape
Dec 9, 2009My application has a lot of dynamically loaded shapes... Now i am working on an interface to change the color properties of each Sprite. The first idea was a simple colorTransform. But afaik this only allows for transforming the existing colors. I also want to be able to define a NEW fill, i.e. GradientType.LINEAR / RADIAL.
SOLUTION 1: There may be an undocumented method to retrieve a graphics current points. With that i could loop through this Array with lineTo and redraw the current shape with the new solid / gradient fill.
SOLUTION 2: Create a newSprite with the chosen GradientType, size it by currentSprite.getBounds(); and then use newSprite.mask = currentSprite; to fake my desired fill... However, i am afraid of the impact this creates on the application as there may be more than 200 of these Shapes displayed on stage... overlapping each other.
