I'm trying to break up a square or rectangle into a large number of randomly sized squares or rectangles so that none are overlapping.How to fill a square with smaller squares/rectangles?The solution seems to be either through bin packing or some sort of tree map.But what I'm looking for is the actual algorithm in Java, Javacript , actionscript or even C.
View 3 RepliesI'm trying to figure out how to tile a rectangle (the stage) with an arbitrary number of rectangles. Simple tiling where all the tiles are the same size and simply stacked in a grid.I'm doing this with a resizable layout and a number of tiles that is arbitrary and will change over time.
Given a more or less 4:3 or 16:9 monitor I would like a solution that tends toward minimizing the perimeter of the tile and being similar in aspect ratio to the screen. I realize that if I have a prime number of tiles that I won't be able to make a nice grid, but other than that it seems there should be some way to do this.Lets say I have 231 tiles I need to arrange. The factors are 1, 3, 7, 11, 21, 33, 77 and 231.If the screen is really, really wide 1 x 231. Wide but not not as crazy wide as before 3 x 77. And most likely 11 x 21 is what I would need.So is there an easy way to do this on the fly? Is there a pre-calculated way to make it easy?
how could I randomly place x number of rectangles on stage so that they dont overlap?
not tween, just place?
I would like to link the red squares to the blue square in 3D with CS4 only (please no papervision or sandy...)I'm very closed to the solution but I still have a wrong z (visible when you move the mouse to a corner for instance)

The main function is drawLines()
We have a 100 by 100 px square.
How would one split this up into N number of random x/y rectangles?
And more crazy, how could you then position these back in order?
I checked out 2d Packing but its not really what im after.
I am trying to make a Grid that is equal to the width and the height of the flash movie. I have a movieclip called box which is 30x30, and want it to repead along the x to form columns and along the y to form rows so that it makes a big rectangle of smaller squares. For some reason it looks like this:

I want to create randomly sized circles which act magnetically to eachother. They should start on random positions and then find the perfect order. They shouldn't overlap. What are the things I have to deal with here?

View 2 RepliesI am trying to draw a set number of squares in a grid type layout and have pretty much gotten it to do what I want. The
problems is that I want to be able to manipulate each square individually later on and I'm pretty sure I need to assign each one a unique instance name.something like "square_0_0" all the way down to "square_10_10" (it's a 10x10 table of squares).how do assign a unique instance name to each square as it's added to the stage? I attached the code I currently have running.
I have the following AS code to draw a single rectangle using mouse, but I need a different code that allows drawing multiple rectangles and the selection/exclusion of individual rectangles like a modeling tool (eg.: MS Visio).

View 2 RepliesI'm looking for an algorithm that will break down a number into n chunks, so that the sum of the chunks will equal the original number. Example - take 30,000 and break it into 100 random numbers - but the sum of those numbers needs to be 30,000.Seems there must be some algorithm to do this, just not sure what it is called.

View 1 RepliesI've been porting a Flex 4 codebase to iOS using the adobe packager, but have run into a snag when trying to package our whole codebase. The packager runs for a while and then throws an OutOfMemoryError - even if I increase the java heap size to 4GB. No single piece of code seems to be causing the problem, as it compiles successfully if I cut out large chunks of code, and I can change which chunks I'm omitting. It might be related to the size of the code itself.I've logged a very detailed bug report with adobe here: ou can package to reproduce the issue, a ruby script that generates actionscript codeto generate that AIRI file, and a summary of all of the things I tried before logging the bug.
View 2 RepliesWhen getting the rotation of a movie clip I sometimes get a number like this: -1.4033418597069754e-14
And this number seems to break simple math. see my code below:
var thisRot:Number = rotation;
trace("thisRot: " + thisRot);
//outputs - thisRot: -1.4033418597069754e-14
[Code].....
How can -1.4033418597069754e-14 round down to 0? And Math.round(thisRotAbs) also results in 0. So how can this be? And how can 180 - -1.4033418597069754e-14 = 180?
I have this code which works fine when selecting a small number of images.

However, when selecting a large number of images (1000+), the fileList isn't initialized yet when the SELECT event is dispatched. Is there a way to wait for the fileList to be initialized?
I'm building my first Flex custom component, in Flex 3. It is a data table based on the 'Grid' container class, with a simple text Label in each cell. (DataGrid and AdvancedDataGrid were not appropriate starting points for my needs.) The component works quite well using smallish tables, but I tried stress-testing it using a larger table, and have been disappointed by the results.
The component creation process has some slow spots, but those are in my power to optimize and aren't my primary concern. What worry me more are what appear to be limitations in the Flex framework itself.
This 'large' sample table has a bit over 7000 cells in it. This is largish, but still 1-2 orders of magnitude less than the biggest I need to accommodate. In standard Grid structure, the main portion of the component consists of a Grid with 400 GridRows of 16 GridItems each, plus a few other smaller ancillary Grids.
Once the table renders, I find the following:
Mouse-related events are slow to fire. Specifically, I have rollOver/rollOut event handlers registered on each table cell, to let me highlight the cell under the pointer. On a small table, I could move the mouse over the table very quickly, and the highlighting would follow the pointer in real-time. With the larger table, the highlighting is very jerky, changing only about twice per second, skipping over many cells.If I place the mouse cursor over the component and leave it there, my CPU is pegged (one processor core, anyway), and stays that way until I move off of the component, when it drops to idle. My component isn't doing anything at all at this point.
It feels like Flex simply cannot scale to support component trees that are this large. I shudder to imagine how it would behave with 100,000 cells. Perhaps I'm pushing the Grid beyond its intended use, but having an object per table cell doesn't seem like an unreasonable model, and ~14,000 objects in the tree (a GridItem and a Label per cell) seems pretty modest.
I had to manipulate a large number of XML and GIF files. In this case I will need to use a compressed file, like zip. if the flash can access this type of data like the Java do.
