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 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'm using a transform matrix as part of a bitmap draw to select an area of my target rather than drawing from 0,0:
var bmd:BitmapData = new BitmapData(target.width,target.height,true,0);
var mat:Matrix = new Matrix(1,0,0,1,-target.x,-target.y);
bmd.draw(this,mat);
[code]......
how to scale down flash images using BitmapData and Matrix?? I'm using it for fullscreen so that the images are always perfect. I've been tampering with this, but cannot get it to work properly.
View 3 RepliesIm currently building a little 3D particle engine in flash the uses sprites.to set the position of each sprite I am using the projectVector function below. (the viewTransform matrix is the particles world matrix concatenated with a perspective projection matrix)
var projectedPoint:Vector3D = Utils3D.projectVector(viewTransform, point);
sprite.x = projectedPoint.x;
sprite.y = projectedPoint.y;
[code].....
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 RepliesHas 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.
I've got a text field that is deep down in a hierarchy of DisplayObjects. The root object is scaled by a variable factor.I want the text field to display it's text in a specific font size, but the text field scales because it's a child of the scaled root object. Is there any possibility to prevent this? I didn't find something in the Adobe documentation.
View 2 RepliesIn AS3 flash - I have a textField with a CSS in it that looks like this:
body {
fontSize: 10%;
}
When it runs, the font is small. When I click the full screen button, I expected the font to increase proportionally because I set it for 10%. However, this is not working, the font stays at the same size as when not in full screen. I have debugged the onResize event and I can see the style fontSize=10pct when I log it out.
Am I misunderstanding the meaning of % here? I was hoping it would increase the fontSize automatically when going to full screen mode, but that does not appear to be the case.
I'm trying to make a text effect where on every frame the textfield increases in size and decreases in opacity. I'm using the scaleX and scaleY properties of my dynamic textfield to enlarge, but it's doing so keeping the left registration point fixed. I want to make it scale up radially outward, or with the center point fixed.
View 4 RepliesSo I've got one more problem because the font size limit on 127px I need to scale my dynamic text so it can be bigger. So here the code I tought could work:
this.createEmptyMovieClip("text1_mc",1);
[Code]....
Scenario: main moveiclip with 4 other clips in it. I want the rolledover clip to scale up and all the others to scale down and blur.
Question: What is the most effiecent way to code this. Would it be a "for in loop"? I am trying to minimize the code and would rather not use a whole bunch of if then statements.
I want my flash content to scale when I scale my browser window.
View 5 RepliesHow can I convert the current scale of the instance to 100% so I can easily "visualize" and manage the instance when I modify its scale? Here's the actionscript, it works, but I just want the temp._xscale and temp._yscale to be in percentages, not real numbers.
Code:
USflag.onMouseDown = function ()
{
var temp = USflag;
onEnterFrame = function ()

One last thing, what's the tag you have to put that is designed for boxing actionscripts? I'm suing [ code ][ /code ]

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 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 <-B
0, 0, 0, 0, 0 <-A
What does each thing do?
I 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.
Code:
var _reflectionHolder:Sprite = new Sprite();
addChild(_reflectionHolder);
_reflectionHolder.y =_targetObject.y + _targetObject.height / 2 + 10;[code]......
I ran into an issue with an app that I have been working on.The application lets a user draw a rectangle, which base class is UIComponent, on an SVG Canvas. The user can rotate, skew, scale,flip horizontal and flip vertical the rectangle. Then they can drop an image into the rectangle.We just cloned the rectangles matrix and applied it to the image and the image would transform the same as the rectangle. Well now we have changed the way the app works.
Now we don't want the image rotated or flipped on the initial drop, and this is where I'm having trouble.I was wondering if there is a way to always find the true top left of any rectangle no matter what kind of matrix is placed on it. I can find the center of the rectangle but when a user flips the rectangle the center point is outside the rectangle.Instead of finding the center I would like to find the topLeft.I have tried several things. Like transform.pixelBounds, but this gives me big numbers like 2200 instead of 400. I have also looked at senocular.com but not sure that I understand it.I just need a dynamic way to always find the top left.
I have some problems with doing Matrix transformations on a MovieClip with a Textfield. As soon as I make a matrix transformation the textfield of the movieclip disappears. And I can not get it back.
