The link elements I'm talking about are single words, so they are not wrapped inside the container, which means that they should have a single bounding rectangle. But how do I go about finding this rectangle? I'm familiar with Flex3 but don't know enough about the new Text Layout Engine in Flex4.
View 1 RepliesI have a rectangle of any arbitrary width and height. I know X,Y, width, and height. How do I solve the upper right hand coordinates when the rectangle is rotated N degrees? I realized if it were axis aligned I would simply solve for (x,y+width). Unforunatly this doesn't hold true when I apply a transform matrix on the rectangle to rotate it around its center.
View 2 RepliesThe AS3 getBounds function returns a rectangle that is not fitting tightly to a rotated ellipse. Instead it returns an axis-aligned rectangle based on the bounds of a rectangle whose width/height corresponds to the max/min diameter of the ellipse and follows its rotation.
Stack Overflow Q/A about the math of ellipses and bounding boxes
Based on this I took a stab at coding a solution in AS3. So far I have been able to produce a rectangle that fits perfectly along the x-axis, but as I rotate my ellipse it acts very weird along the y-axis. Rather than alternating between 2*r_min and 2*r_max while rotating, it alternates between 2*r_min and 0. My best guess is that I have done something wrong when solving the differentiated t for gradient -> infinity...
Here is an example from my code:
var r_max:uint = 45;
var r_min:uint = 20;
var rot:Number = ellipse.rotation * (Math.PI / 180);
var t_nil:Number = Math.atan( -r_min * Math.tan(rot) / r_max);

In AS3, I have a Sprite that has a Z axis rotation applied.How do I calculate that Sprite's dimensions (it's original size) from Sprite.rotationZ and Sprite.getRect(...)?
View 2 RepliesIs it possible to make a bounding circle instead of a bounding box?The objects should bounce INSIDE the circle.I have now a bounding box outside the circle, but the objects exceeds the circle at the corners.
I was thinking of making an array of Points on the edge of a circle and when the object is < or > then do something... but that would be a lots of if/else statements.
What I need to do is find the rectangle of a rotated rectangle. I have a house that is diagonal and I need to find the rectangle of the bottom of the house so I can check for collisions. I was hoping to use the rectangles to find intersections. Something like - if (playerRect.intersects(houseRect.bottom){ do something };Every time I try to get the rectangle of a rotated rectangle, all I get is the bounding box which is not rotated.
View 4 RepliesI have a BitmapData with 2 red circles. I want to find the rectangle area or each circle. If i use [B]getColorBoundsRect[/B] I get the smallest area enclosed by the 2 circles. How can i go about this and get individual area of the circles?

View 1 RepliesI am working as a developer on a Flex/Air application and we are using the buggy Flex RTE (RichTextEditor) to let the user manage his notes. At the moment I am trying to evaluate how costly it would be for us to build a new text component using the TLF (Text Layout Framework).Really important is the question if we can import the HTML text, produced by the RTE straight away. I know that there are some limitations regarding lists with TLF 1.1, but does it work in general?
I have just tried to grab some HTML formatted text from RTE like:

View 3 Repliesi'm trying to add whitespaces in front of my text, but flex removes all but one whitespace from the text. So i can't format the text.
Here is the specified line:
<s:p> - Lorem</s:p>
<s:p> ipsulum</s:p>
Here its shown correctly but when running the swf it reduces the whitespaces of the second line. Of course i tried to use CDATA but this didn't work too.

i am trying this:
open google docs, new document, and type in: hello world (world bolded)
then download it as html(zipped)
i unzip the html file, and save it to the assets folder in src folder of my Flex app
i have a Spark:TextArea instance and i want to do:

myTextArea.textFlow = importer.importToFlow(htmlSource);
where htmlSource should point to the saved html file somehow
how do i do this? i tryed embedding, converting to ByteArrayAsset and to String, but i always get the source of the html file and not it's rendered rich text (ie "hello world).

View 1 RepliesI am using text layout framework textflow in Flex 3 to get embedded images. In the edit field for the application the user can apply formatting. This all works fine except if the user deletes all the text they have entered and then starts typing again then the formatting is lost.[code]To setup the initial formatting then similar code to apply the formatting when the user changes it.So how can I stop the user from 'deleting' the formatting if they delete all the text?
View 1 RepliesFor those of you still with me, I am tasked with making some scrollable content in Flash. Load in a TextFile using LoadURL(), then display it. To get the text, we've written our own class TextFieldExtended, which is basically just there to give the textfile location to the constructor and then have the class do the various steps of getting it and loading it for you.So I needed to get a Scrollbar, which I got hereThe thing is, it works with Sprites.After trying to get it to accept TextFieldExtended, I bumped into a block, since the scrollbar relied heavily on a Sprite property that TextFieldExtended didn't have or could have.
So I tried adding the TextFieldExtended instance to a Sprite instance using addchild.A problem occurs here that I do not know how to handle. It seems that a Rectangle is drawn and the Text is drawn on that. I say this because the scrollbar moves the Rectangle up and down a bit, but the text doesn't scroll, just the Rectangle it is positioned in and the text then moves along with it.My question: can this be fixed, or is does this implementation of scrollbars need a lot of adaptations before this is possible?
I draw a rectangle i should see a little bold circle to indicate a perfect rectangle, I seemed to lost mine, can somebody please tell me how to get it back!
View 2 RepliesI am trying to convert a rectangle(actually multiple rectangles) to a curved rectangle. I think it should be pretty easy but I guess i am stupid. Basically I would have a start position and stop position (many of these), and they would be converted to curved rectangles and follow in a cicrle around.
View 0 RepliesI would like to create a rectangle inside of a rectangle, starting approximately 15% inward from the right side of the other rectangle.
I know how to create rectangles with:
Code:
var newHotRect:MovieClip = new MovieClip();
newHotRect.graphics.beginFill(0x00FF00);
newHotRect.graphics.drawRect(0, 0, 100, 100);
addChild(newHotRect);
But how would I make another rectangle on top of that (the black one pictured) that is approximately 15% from the right?
I toyed around with .right, and .bottomright with no success. Can anyone lead me in the right direction? or even finding the x and y of the upper right or bottom right side of a rectangle?
how to respond when a rectangle hits another rectangle? I already know how to detect the collision, I just don't know how to respond to it. I'm just trying making a simple side-scrolling platform game where I have platforms I can walk on and bump against on all sides. I have searched everywhere and just can't find the tutorials I'm looking for.
View 6 RepliesI wrote the following code for drawing a rotate rectangle
var s:UIComponent = new UIComponent();
s.graphics.lineStyle(1, 0x0000FF);
s.graphics.drawRect(50, 50, 200, 200);
s.rotation = 30;
template.addChild(s);
Where template is a canvas. Its rotate nicely but the problem is the position is not in right place. i.e. it is not in (50,50) after rotate.

Basically this is not working. I used this question to improve - still nothing.Why doesn't this Flex App draw a simple rectangle?
I have a rectangle that I've created and set its individual properties like so
var aRect:Rect = new Rect();
aRect.width = "15%";
aRect.height = "15%";
Problem is the compiler chokes on 15% and "15%", with or without the quotes, neither works.
the code is straightforward and my Intention should be clear. Still i can get this to work:
<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark"

How can I set something like corner radius for the default rectangle which appears when an item is hovered?
