View 1 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 know it's possible to scale and rotate an object by using some actionscript. Is it also possible to distort an image?
For example; keep the topleft corner and the bottomleft corner of an object at the same position and put the topright and bottomright corner of the same object 25 pixels down.
I tried many Flash .swf before and they all can be scaled freely -- by using a width and height in the HTML, and sometimes in the URL params or flashvars. But is it true that all Flash object can be scaled? For example, can some Flash objects using absolute coordinates to plot graph so that every 10 pixels it marks 1, 2, 3, 4, 5, and no matter what is done at the HTML or any where else, it just won't scale and the browser can't do anything about it either? Is there a way to scale it to half the size for that graph? (that is, 1, 2, 3, 4, 5 is separated by 5 pixels instead of 10 pixels)
View 1 RepliesLet's say I have a movieclip, which contains a simple circle draw on it. What I need is to scale the movie clip along a random line (not vertical or horizontal only). The picture attached probably illustrates what I mean. The only idea I can have is to combine usual scaling and rotating.

Like in this example but with actionscript instead of motion tweening.
I have a little problem, I'm writing an app, where flash attaches a movie with attachMovie and in addition, I add an object with its _x,_y,_xscale and _yscale. Now what I need to do, is not to attach a movie, but to load it with MCL. The problem is,that I don't know how to attach an object with its _xs and _ys to a movieclip loaded. Furthermore, when loaded,it doesn't appear in a library, so I could attach it. Setting parameters manually would take tons of time, so I'm looking for most "economical" solution.

View 9 RepliesWhen I created a Bitmap object from drawling the pixels of an image and then scale that Bitmap too large (or even too small) the image disappears or in some cases distorts in what appears to be random pixels barfed all over my screen.
In order to show you this I have made an example: [URL]
(click the plus button any more than 8 times and poof! the bitmap disappears)

I have had some help but still not understanding this.
How can I scale an object from center after it is dragged by the user?
Currently I have this:
function onSliderChange(e:SliderEvent):void
{
scaleClip(slider.value);
}
[Code]...
With this code the movieclip jumps back to the center of the stage each time I call the scaleClip() (move the slider). I would like the object to scale from it's own center regardless of where it is on the stage.
I need to scale and move a object at the same time.
Like in this example but with actionscript instead of motion tweening.
I drew a farm and I want to be able to move the animals around, also to make it a bit more real, they need to scale down proportionally along the y axis, I have been searching for a tutorial or download to no avail.
View 9 RepliesI am basically trying to create a display object transformation manager which will allow me to scale/rotate objects. I am currently trying to figure out how to rotate an object so its corner follows the current x and y of the mouse. I always get confused on the math of things like this. I know how to listen for the events and everything, I just am unsure of how to calculate the amount of rotation to apply. I will probably be rotating via a Matrix so I can rotate the object around its center, rather than the upper-left corner of it. My question here is: how do I get values when I don't want them constrained, like scaleX and scaleY?
View 1 RepliesI have a div with a flash object in it. That div is going to pop up in a modal triggered when a user clicks a thumbnail of the flash presentation. The problem occurs when I try to use the scale effect to scale in or out, it errors out.
Here is the HTML:
<div id="modal">
<object id="presentation" width="720" height="576" classid="clsid:d27cdb6e-ae6d-11cf-96b8-444553540000" codebase="[URL]" align="middle">

I've created an mc which functions as my map and controls to go with that which allow the map to be moved around and key points navigated to and zoomed in on at varying zoom levels.I'm using scaleX and scaleY to scale the map mc and a list of x and y positions to correctly position the map for each key point.When I want to go to a certain area I perform this calculation (offsetX and offsetY are the center of the screen):
newX = posX * scale + offsetX;
newY = posY * scale + offsetY;
Then I tween the position and scale of the map to smoothly scale and move the map to the correct position:
var tween = new TweenLite(_background, EASING_SPEED, {x:newX, y:newY,scaleX:scale.getScale(),scaleY:scale,ease:EASING_TYPE,onComplete:moveToComplete,onCompleteParams:[room]});
I now need to implement a zoom in / out function and this is what I'm struggling with. The zoom should use the center of the screen as the reg point for the scale, so I've been trying something along the lines of the following to get the correct positioning:
var newX = offsetX - (offsetX - _background.x) * scale;
var newY = offsetY - (offsetY - _background.y) * scale;
So in my mind this gets the distance from the current position of the map relative to the center point of the screen (offsetX, offsetY) then scales that distance by the new scale. However, this is clearly wrong because it's not working and the positioning of the map is wrong.I've also tried using a transform matrix to get the correct values but I know even less about them and not got the right results.
function scale(target:MovieClip, center:Point, scale:Number):Point {
var m:Matrix = new Matrix();
m.translate(-center.x, -center.y);//move the center into (0,0)

What I am doing now is loading a .png image with a Loader object. After loading the file I cast the loaderInfo's content to a bitmap and set the smoothing value to true. This works without a problem until I reach a ScaleX and ScaleY value less than 0.5.
For example, if I have a 1000x1000 object, scaling it down to 200x200 causes the bitmap smoothing to no longer work.[code]...
getting a bitmap to apply smoothing properly after being scaled very small.What I am doing now is loading a .png image with a Loader object. After loading the file I cast the loaderInfo's content to a bitmap and set the smoothing value to true. This works without a problem until I reach a ScaleX and ScaleY value less than 0.5.
For example, if I have a 1000x1000 object, scaling it down to 200x200 causes the bitmap smoothing to no longer work.I can reproduce the problem using all of the following Sizing methods:
Change the scaleX and scaleY properties on the bitmap. Directly change the height and width properties of the bitmap. Add the bitmap as a child of another sprite and change the scaleX and scaleY properties of the sprite. Add the bitmap as a child of another sprite and change the height and width properties of the sprite. Creating a new BitmapData object with a matrix scale and then drawing the original BitmapData onto it.I've also tried some other workarounds that I found when searching, such as:setting the scaleX of the image to 1.001 or 0.999 forcing the height and width of the Bitmap object to be even numbers.
Below is some sample code for reproducing the problem. (I am running this locally so I have a copy of testimage.png in my bin-debug folder)
public class MainObj
{
public var comp:UIComponent;
public function MainObj()

I have developed a flash app in AS3 that allows you to drag objects around on stage, save,and load them. When the "save" button is pressed, it then loops through each item on the stage and gets the coordinates (x and y) for the bottom left corner and the top right corner. Code:
Code:
ActionScript Code:
var bottomLeft:Point = new Point(-50, -50);
[code]........
I am learning AS3 and trying to get an object to be able to move / rotate / scale and drag and drop. I found 2 seperate tutorials one does button clicks to move and rotate code.[code]When I add the second lot of code to the first app (ie add a layer and insert the script ) change myPoint to rocket . I get the following errors:'{' expected
View 1 Replies1. Is there a way to scale up an object from its center even if its registeration point is at the top left? can that be done using TweenMax?2. can I apply the same tween on two objects at the same time? basically what I want to do is load up an image to the stage, and then tween its scale from 0 to the original size along with another movie clip behind it that would form some sort of a border for the image. and I want to scale them up from the center.
View 5 RepliesWhen you load a object through flash, you can set the rotational/scale point, but when you load it as a loader object or sprite, how do you change this point?
In this instance, I want to change the height of a sprite that is filled with a rectangle so that it shrinks down, not up.
Right now:
var colored_bar:Sprite = new Sprite();
with (colored_bar.graphics) {
beginFill(0x9e1819, 1);
[Code]....
The way I am doing it currently is moving the y position everytime I take away soem of the height, so it looks like it's moving down, but I'd think moving the orientation point at the beginning would be faster
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 6 RepliesSo I have this Photo class than handles loading a pic, and dispatches an event when the loading is done with:[code]which is simple and works, but now I'd like to make something more advanced. I'd like to dispatch the load ratio.So far I have extended the Event class, with my own EventRatio class, and I can put properties on that class. Which is cool, but I need something more dynamic than just sending a fixed value.So, what is the best way to connect the Loader object of the Photo object, with the EventRatio object?
