ActionScript 3.0 :: Matrix Array Row/column Insertion?

Jan 13, 2011

I'm trying to make game like bubble spinner....I created a grid 2d array for this game... But got stuck at insertion of a new row/ column to the current matrix position.How to insert a row/ column to a matrix after its already created ie, if i have 2d array of size 4x4

[1] [2] [3] [4]
[5] [6] [7] [8]
[9] [1] [2] [3]
[4] [5] [6] [7]...

then i have to add a row like 0,0,0,0 to the 3 rd row and need the shift of 3rd row to 4th and 4th row to 5th.

ie,
[1] [2] [3] [4]
[5] [6] [7] [8]
[0] [0] [0] [0]
[9] [1] [2] [3]
[4] [5] [6] [7]

ActionScript 3.0 :: Generic Array Deletion & Insertion?

Jun 23, 2010

I was going through the options the generic Vector class offers to delete and/or insert items from/to an array, and it seems to me that the only way is by using the Splice method. For me, this method does a lot of work I dont utilize in my code (like creating a new array as a result etc.), hence
 
is there an optimized way how to delete a certain item from a vector, instead of calling myVector.splice(idItemToRemove,1) ?

ActionScript 2.0 :: Matrix Algebra And Matrix Inverse?

Apr 5, 2003

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.

Flex :: Flash - DataGrid Column Width: One Column To Rule Them All?

Nov 16, 2010

I have a Flex 4, mx:DataGrid with the following (pertinent) properties set:

width="100%"horizontalScrollPolicy="off"

I have the minWidth set on all of the DataGridColumns and the width set on one of them. If I simply maximize/minimize the display (in browser or stand-alone flash player) of the application, the columns scale up and down nicely. But if you grab the edge of the application and drag it to make it bigger, only one column grows really big. When you drag the size down again, the one column remains big, but all of the other columns get squished way down.

Flash :: Get Scale Of A Matrix Object?

Mar 14, 2011

Most often, questions are asked about how to scale a DisplayObject, and the answer is usually to use a Matrix.

My question is, how to you GET the scale of a Matrix (scaleX and scaleY)?

There's a Matrix.scale method to set the scaleX and scaleY, but it doesn't return a value, and no other properties exist to read it back.

The reason I ask, I'm using object burried deep down into a Display list, and each may be transformed. So I use the child object's sprite.transform.concatenatedMatrix getter, but am stuck at this point on how to read the scale from it.

It is now flat, no 3D rotation or shearing But what I want is that this movieclip has a rotationX, or that it is a bit in perspective like this: As I said, I can't use rotationX, so I have been playing around with Matrix. But I can not get it right.Here is how I try to do it

And this is the result get the matrix right, or is there another way?
