I'm assigning raw matrix values through Matrix3D.rawData.When assigning certain matrices it yields the following error:
ArgumentError: Error #2188: Invalid raw matrix. Matrix must be invertible.
However, I believe the matrix data I'm passing represent an invertible matrix!Is this a (known) bug? Or is the matrix not invertible and is my math failing me?

I am trying to rotate a Sprite in three dimensions around its centerpoint, and I am struggling to understand some of the behavior of matrix3D.
Ive overridden the set rotationX, rotationY, and rotationZ methods of the Sprite as follows:
override public function set rotationX (_rotationX:Number) : void {
this.transform.matrix3D.prependTranslation(this.width/2.0, this.height/2.0, 0);
this.transform.matrix3D.prependRotation(-this.rotationX, Vector3D.X_AXIS);
[Code].....
I am using prependTranslation to correct the centerpoint of the rotation, and the first prependRotation to cancel out any previously-applied rotation.
Testing it out, rotationX works exactly as expected, and the Sprite rotates around its horizontal axis.
rotationY and rotationZ also appear to work fine. However, there is one problem: whenever rotationY or rotationZ are set, all of the other rotation values change as well. This is not a problem with rotationX -- if I set rotationX, nothing else changes. But if I set rotationY or rotationZ all the rotation values change, which is a problem for my app (which is trying to save and restore values).
I think I am just lacking some understanding about what is going on with matrix3D. How can I implement this so there is no interdependence between the values?

I have a simple 3D tween that I created to 3D rotate a bitmap logo (in a movieclip) on it's x axis. It works great during testing but I noticed that when I tested it on the website that the pivot point was totally off! I had to use the matrix.prependTranslation() method to alter the pivot point so that the clip would rotate & remain centered. This is totally broken when I run in the browser but works great outside of the browser?

I'm studying John Lindquist's example from here: [URL] I'm trying to figure out how to add restrict his matrix3d method, so the sphere has limited movement.
Code:
Select all override protected function onRenderTick(event:Event=null):void {
var currentMousePoint:Point = new Point(viewport.containerSprite.mouseX, viewport.containerSprite.mouseY);
if(isMouseDown) {
var difference:Point = currentMousePoint.subtract(previousMousePoint);

I made a cube with as3. I wanted it to rotate in the Y Axis according to the horizontal mouse movement. It works nice when this is all I want. But if I try to also make it rotate on the X axis with the vertical mouse movement, things get screwy.
This happens because the transformations are added in the global coordinates, not the local ones. So, for Example, if I wanted the cube to rotate 30 degrees along its Y axis, I have to find a way to translate that into the global coordinates, and then apply that to the matrix3D of each face. I need a local to global translator.

I have a decompiled swf which I've heavily modified consisting of two large buttons with identical behaviors. When I assign a url to the button layer after double clicking on the left button, then the right, the behavior are both applied to the same sprite which, when viewed in the library, only represents the left button ("url one"), while the second url is missing. There are two separate layers for each button on the scene, yet I can't get separate urls applied to them because of this.I could just create two separate files, but that would add to the amount of code...
View 7 RepliesI'm currently translating an application from actionscript-3 to Java code and got stuck with a variable assignment problem.
There is such block in as3 application: var num:*=0; num = 5.5;
As far as I understand AS3, variable is declared of an unknown type, which is resolved during the first assignment =0 meaning it will become int. Am I right?
So does that mean that by assigning 5.5 to it, the Number will be converted to int, and I will have num==5 in the result? Or will it become Number after assigning Number to it?
Added:but I don't have any Flash environment to test it myself. I'm converting one of the utility methods from actionscript to Java and got stuck with this problem.
Added 2: The question is, if num will contain 5 or 5.5 at the end of this block?
If I have a combo box with code:
Code:
var listenerObject:Object = new Object();

i have a main page that loads a swf of an xml photogallery onto the main stage. I used the classpath in actionscript settings to target the actionscript files and xml data. So far, everything works well. Now, a button on the stage unloads this swf and then loads a second photogallery. The problem is that when it appears, it contains the same data (images) as the first photogallery. This is because it is using the same classpath as the first gallery. My question is how can i assign each gallery its own class path. It seems that only one can be selected at a time.
View 3 RepliesI was wondering if it's possible to assign seperate MC's the same instance name. Say, like, 'boundary' so I can have various boundaries and not have to worry about it.I could use a for loop and name each boundary something like bounds1, bounds2, bounds3 etc. but I'm wondering if there is an even easier way.

I followed a dynamic gallery scrolling thumbs tutorial and then changed it quite a bit to fit my needs.
I basically added a previous and next button and image title box.
It all works great apart from one thing.
e.g. I click on thumb 5. I then use the next button and go to say... image15. I then click on thumb 9. When I use the prev or next button again it will resume from image15, but it should then carry on from thumb 9 as that was the last change I made.
I thought this would be as simple as assigning the thumb variable value to the image number variable. i.e myID = id; but it doesn't work. my variable myID actually loses its value when I click the thumb image (I used the trace to clarify).
Here is the code.
PHP Code:
function bttnClick(event:MouseEvent):void{
bttn.gotoAndStop(1);
root.logo.visible = false;
myID = id;

I have a 4x4 set of square buttons that I need to give instance names to. They will be named 'btn_1' thru 'btn_16'. Is there any shortcut to assigning the names or do I have to go through 16 times clicking on the button and clicking down to the 'instance name' text box?

The AS3 code i'm using works the first time, but then goes a bit crazy and stops working for some reason. Please see my attached fla.

View 1 RepliesI tried the drag and drop demo at [URL]. It works well allowing me to drag an item and have it register when it is dropped on the correct target. I want to modify it so that I can drag an item to multiple locations... not just one. My desired application is the ability to drag pendents or charms onto a bracelet or chain and have them "snap" to the chain. With the above demo, I can see how 90% of it would work, but I cannot figure out how to have multiple targets named the same. The bulk of the code is attached.
The line I believe needs to changed is this one:
if (event.target.dropTarget != null &&
event.target.dropTarget.parent == myTarget){
I need this part :event.target.dropTarget.parent == myTarget
to read something to the affect of:
if item being dropped is over object A OR object B OR object
C OR object D than ... rest of my code

I'd like to figure out how to get these four skulls to move on a constrained X axis on enter frame, and on CLICK, I'd like them to reset to their original positions.Example:On frame 1 is an mc I created named holder. Inside there's an mc named box. Inside box are four mcs, circles1-4, inside the circles I have four skulls.I've also created an mc called rectangle and dragged it over the first skull to get the coordinates I want using the following trace:
trace(rectangle.x, rectangle.y, rectangle.width, rectangle.height);
Resulting in these coordinates: 143.95,119.05,131.15,61
So, this works MOUSE_OVER the circles

I am using swfobject v2.1 to pass flashvars to my swf and I was wondering what the best or preferred way to pass those flashvars values to AS3 variables inside the swf.
snippet of javascript inside my html file from swfobject's required code.
Code:
....
var flashvars = {};
flashvars.myVar1 = "one";
flashvars.myVar2 = "two";
[Code].....
I essentially want to be able to pass a handful of flashvars to my swf and assign their values to AS3 variables inside (such as flv file url, skin, background colors, autoplay true/false, etc... my approach would be that certain AS3 variables would have default values (realizing my above examples do not show this), while others would require them passed from Javascript (flashvars).
is there anything changed in actionscript in flashbuilder 4? i'm new to as3.... why is following for loop not assigning value to array ?i tried in various ways, but could not get it

I have a problem which i hope some one can help me with. I am loading in data from an XML file. This works fine, i can trace the contents of the XML file. The problem i have is this. I want to save each attribute to a class variable so i can call upon it with a getter method.The code is below:
Code:
package XML
{
import flash.events.Event;
import flash.net.URLLoader;
[code]....
If i trace(path) inside the processXML() its displays as expected. but if i fire my getter method path() im returned a value of null.
I need to set movie clips at specific frames from an existing array. For example, if I have the array [4,7,3] and three movie clips, I want the first clip to be at frame 4, the second at frame 7, and the third at frame 3. Except I have 100 of these, not just three.
Here's the code I'm using to test it out on a single movie clip. It isn't throwing up any error messages, but it isn't working, either, and the movie clip remains stubbornly set on the first frame. 'Randomorderlist' is the array, which is working perfectly. The trace is also working correctly and displaying the number of the frame I want for the movie clip.
function assignframe():void {
boxsymbol(gotoAndStop(randomorderlist[0]));
trace(randomorderlist[0]);
}
assignframe();
I think I might know why it isn't working, but I'm not sure. 'boxsymbol' is the class name rather than the instance name. I first tried the instance name, but it came up with a 1180 error and stuffed up the whole SWF badly. This was the only way I could fix it. Also, Flash wouldn't let me use the same name for the class and the instance. It forced me to use classes, even though I don't really want to.
I have a little problem and I guess it won't be difficult to solve, but I am still learning to create codes and I get stuck every once in a while (more every than once haha). What I want is to create to different arrays, one for all the buttons I have, and the other for all the instances of the frames that will take me when I hit each button. So for example if I hit mybutton3, it should take me to frame3.
