I have the starting point of a rectangle, and the rotation of the line that I would like this rectangle to be parallel to. My initial thought was to create a Rectangle() then rotate it, but there doesn't seem to be an easy method rotate a rectangle. From this rectangle I create I can obviously get the four points, but I need these to be adjusted based on an angle of rotation that I pass it.
View 1 Repliesvar snapshot:ImageSnapshot = ImageSnapshot.captureImage(someSprite);
var file:FileReference = new FileReference();
file.save(snapshot.data,'abc.png');
n the above code I am able to capture an image.But I also want to apply a scalingMatrix(for zoomIn/Out) and a clipping rectangle to it. How to do it? I tried capturebitmapdata too, but with that I can't even get a proper image. See here. So I don't want to use that.
Okay so I have two import pieces of code involved in this. This first tiny bit is what creates an object called OBJECT_arrow. It is located in the main function of my main class[code]...
It isn't really all that important. Now this next bit is the OBJECT_arrow class. What it does is loads an external png image and draws it. [code]...
How can I rotate an Image eg. 180 degrees clockwise using the Matrix. I can use the following code to rotate the image 90 degrees, but it is incremental, meaing
var matrix:Matrix = new Matrix();
matrix.rotate(Math.PI/2);
matrix.tx = imgControl.content.height;
var bitmapData:BitmapData = new BitmapData(imgControl.content.height, imgControl.content.width);
bitmapData.draw(imgControl.content, matrix);
imgControl.source = new Bitmap( bitmapData);
[Code]...
I found the function:
rotateAroundExternalPoint(m:Matrix, x:Number, y:Number, angleDegrees:Number)
to rotate an object around an external point. The top of the object will always point at the center point which is exactly what I want.
It works fine but its possible to rotate it in an oval instead of in a perfect circle...I think it should be something with the angleDegrees Parameter but im not sure what to do with it. I also tried to set up an own matrix but I failed. Any right direction to orbit an object in an oval, and where the top of the object always point at the rotation center?
my problem is that if i scale, rotate or translate a display object using its transform.matrix i am not getting the value in the display object but the transform is happening like displayObject.scaleX or displayObject.scaleY etc. i get this new transform value using the dislayobject? as i am using a matrix transform manager which actually changing the transform matrix of the display object.
View 8 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.
Here s the link what I m trying to achieve

how to achieve this rotation ?
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.
For 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 am having some dificulty making a path for this enemy i'm trying to create... cause i want him to rotate + move, then stop, then shoot, then rotate back and move off screen... Its easier if you see it.. you can download the swf file in the zipped archive to demonstrate what i mean. I did it there with tweens. Anyway.. i tried and make it but i'm a little stuck on the stopping part... you can also see what i did in the fla file attatched...

View 2 RepliesI followed the tutorial for the Matrix Bitstream Effect here - [URL] utorials/Sp...ndex.shtml - like a slave, downloaded her code and compared, and I still can't see why my matrix will not become random. I put a bunch of copies of the movie clip of the "random" 0s and 1s on Scene 1, and they all slavishly turn to 1s and 0s at the same time, no randomness. Can anyone tell me what I'm doing wrong?

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?
View 41 RepliesAfter reading over the Flash 10 file spec I want to play a bit with transformational matricies.If you have multiple MATRIX records in an SWF do the transforms compound each other?Or is the matrix a complete replacement of the previous matrix?Does flash operate similar to Postscript with gsave grestore like operators which allow the transformational matrics to be saved & restored?
View 1 RepliesI'm trying to use the MatrixTransform class to RotateAroundInternalPoint but it requires that the object I'm trying to rotate has matrix points defined. My question is, is there a way to add Matrix points to a non Shape object so I can rotate it, or is there another class that is used to rotate movie clips around internal points?
View 6 RepliesMost 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.
I was wondering how you can use the matrix to increase the component of the canvas!
View 1 RepliesI have to use Flash CS3, so I can't use the properties rotationX, roationY and rotationZ.I have a movieclip, that looks like this. 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
myMC.transform.matrix = new
Matrix(1,0.15,0.35, 1, 0, 0);
And this is the result get the matrix right, or is there another way?
In the 4 * 5 array that makes up a colour matrix, what do ALL the values do? All I have found is basically this:
0, 0, 0, 0, 0 <-R
0, 0, 0, 0, 0 <-G
0, 0, 0, 0, 0 <-B
0, 0, 0, 0, 0 <-A
What does each thing do?
Unfortunately geometry is not my strong point and I am on a deadline. I am trying to determine if a textfield is larger than a displayObject and that it does not sit outside the x and y of said object. If it is larger, I need to scale it and make sure it is always in the confines of the displayObject space. On a side note, i need to scale the size of the text accordingly.
View 0 RepliesI am trying to copy an image.The green stuff on the first image is a mask(which is not set, its just there to show it)Everything works fine when I dont set a mask to an image (picture 1)But when I set the mask I get picture 2.What I want is to copy a part of the image which is visible when the mask is set. I know what size the mask and image are going to be so I can calculate the size of the area which i need to copy.This is the code I am using, image has registration point in the center, thats why i use matrix.translate (not sure if its the right way).Also there is no image scaling applied (there might be later), thats why I am using matrix.scale.
