As you can see in my code, I'm trying to adjust on the fly the x and y properties so that the movieclip gives the impression to rotate from its center and not from its corner at 0,0
Code:
var myclip:MovieClip = new MovieClip();
myclip.buttonMode = true;
myclip.graphics.beginFill(0);
[code]....
but it doesn't work and the clip does not rotate well
I have a movieclip and when I do 3D rotation from Transform panel, It rotates perfect, center is in the middle of image, and when I apply mc.rotationY, rotation center is in left of the image, aren't 3D rotation from Transform panel and mc.rotationY from AS same? what's up?
View 2 RepliesI 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 am new in action script 3... i am not able to rotate movie clip from center point(movile clip is a containear holding many clips).
View 9 RepliesAs is well demonstrated by a Google search, the rotationX, rotationY, and rotationZ properties turn a display object around the center.
That's all well and good, but I want to rotate a display object about a different point.
I can't believe there isn't a way to do this, but I don't see anything that addresses this question specifically.
I have a b2PolygonShape body and apply a force to it.
_recbody->ApplyForce( b2Vec2(6.0, -6.0), _recbody->GetWorldCenter() );
I want to change the centre of rotation of the body to be more in the front of the body. So that applyForce and also collisions make the body not turn in the centre but more in the front.
I found this actionscript online to rotate a sprite around its center point but I get two errors when I use it. 1084: Syntax error: expecting identifier before leftparen. 1084: Syntax error: expecting rightparen before leftbrace. Also, in place of angleDegrees do I put in the angle I want the sprite to rotate by?
var point:Point=new Point(spr_box.x+spr_box.width/2, spr_box.y+spr_box.height/2);
rotateAroundCenter(spr_box,45);

var m:Matrix=ob.transform.matrix;
m.tx -= point.x;

I coded an entire file based on the top left registration point of my movie clip. I want it rotate it to point at the cursor, but since the registration point isn't in the middle.. its not a perfect rotation around the center of the mc. Is there anyway to rotate it around the center of the movie clip without changing the registration point?
ActionScript Code:
stage.addEventListener(Event.ENTER_FRAME, aimBall, false, 0, true);
function aimBall(event:Event):void {

trace(ball_mc.rotation);
} function getAngle(x1:Number, y1:Number, x2:Number, y2:Number):Number {
var radians:Number = Math.atan2(y1-y2, x1-x2);
return rad2deg(radians);
} function rad2deg(rad:Number):Number {
return rad * (180/Math.PI);

Is it possible that I can have a fixed 3d rotation center for a movieclip.So if I have two movieclips spaced apart and I have rotated them, they rotate in their own axis rather than based on a single axis.

Then I want to rotate the shape at it's center point(200,202) by using shape1.rotation=50,but I find the shape don't rotate at the the center of it's shape. How to realize the function which make shape rotate at its center point?
I am trying to place leaves in a circle to create a flower with code. I run into some problems.Is it possible to rotate the leaves so they all rotate in the direction of the center of the flower? And is it possible to calculate how many leaves can fit around a certain circle radius without to much overlapping?
View 1 RepliesI'm trying to do some augmented reality projects with flartoolkit . I can now put simple 3d objects on my marker and it works fine , but I wanna give my project some events that the user can interact with. I'm trying to trace the rotation of the marker. there's a container:DisplayObject3D which my application uses to add the 3d objects , I traced this :"trace(container.rotationZ)" but it's just returning 0 . I studied another AR application's source code and it was using the rotation of it's container object without problem .and I think I should mention that I'm using the exercise file of seb lee delisle papervision3d course from [URL]. anyone has any experience with flartoolkit? the main functions of my my code is as below:

Is it possible to have the child movieclip rotate separate of the rotation properties assigned to the parent? so ultimately giving the child element it's own axis?I've customized Lee Brimelows (gotoandlearn.com) 3D carousel to spin on the x axis to make it a vertical carousel. I've also rotated that by 45 degrees on the y axis to see all the items, and wrote a snippet of code to hide the left portion of the carousel. The entire carousel is contained within the 'container' movieclip, and inside of that are my carousel items (as seen below), with the larger item being the item in focus.
On rollover of the item in focus, I want to rotate it so it faces the viewer (as seen below),basically removing the 45 degree rotation applied to the container.The problem i'm running into is when you rotate the container (changing the rotationX of the container), the axis basically rotates with it, so when i rollover the next item 'in focus', the following happens..(in the example where it appears how it want it to, the carousel is at a rotationX of 0, so it works fine)
Program A has a cannon that aims to line up with where-ever the mouse is pointing, in 360 degrees, and fires when the mouse is is clicked. Program B has an eye instead of a cannon that should in theory do similar functions when the capslock key is toggled, but instead only has a 90 degree range of motion from the Right of the eye toward the bottom (quadrant 4 only). Where did the ther 270 degrees of rotation disappear to?

i.m trying to create a 3d rotation much like the widely used carousel only the rotation i desire consist of four upright(90 degrees) movieclips resting on a slanted, 30 degree plane which rotate onEnterFrame or following a tween on a oval like path - then pause for a given number of seconds at the four movieclips positions equal in distance on the plane
function around() {
this._x = Math.cos(this.angle) * radiusX + centerX;
this._y = Math.sin(this.angle) * radiusY + centerY;
var s = this._y /(centerY+radiusY);

View 1 RepliesI have a center window and a background in my flash file. I am trying to get the center window to stay in the center of the web browser screen and get the background to expand and fill the entire web browser screen below center window layer. Sort of like this site [URL] I've currently converted the background to a movie clip and have this code.

My flash movie is 1440x900 but the area where all the important stuff happens in within 1024x768, i am trying to keep the middle in the center regardless of browers size or aspect ratio.
I can center the page but it doesn't work as i need it to. If the browers is small (1024x768) the swf is justified against the left edge, but not keeping the middle in the middle of the brower.
[URL] is an example of exactly what i am trying to achieve.
I am watching the tutorial on the motion editor and when he opens the motion editor to edit the Rotation X and Rotation Y values I'm in trouble.My motion editor now only shows Rotation Z but, no Rotation X or Rotation Y. What am I doing wrong?
View 1 RepliesI am trying to do a simple "pseudo 3D" rotation of a movie clip. The clip would "flip" on to the screen. I have created the effect using PaperVision3D, however, the final SWF is about 64k and my project requires a smaller file size. I tried to create the flip effect manually by creating skewed versions of the clip and tweening between them, except this doesn't work because the shape is not tweaked along the vanishing point as it should be. It looks like perhaps I could accomplish what I want to do using the MatrixTransformer but I've not had much luck so far.

I have a pointer that rotates with this code (on the MC):
Code:

How can I control the center of rotation when manipulating CS4's 3D properties? --I mean in code, that is. I've set the 3D Center Point in the Transform Panel, and if I rotate the MovieClip in the IDE, it rotates correctly... but when I manipulate rotationY via code, that 3D Center Point is not used.

I have a client that wants a product to rotate around its axis for a full 360 degree view of the product. The final view needs to be draggable - so a user can use their mouse to turn it left or right. I took photos of the product in 10 degree increments and created a movie clip - but I can't figure out how to get it so a user can control the view: turning the product left or right.
View 3 RepliesI am trying create a rotating circle with buttons/menus around the edges and this would simply rotate around, not like a 3D carousel, just basic rotation of a circle triggered by movement of the mouse on a vertical axis!I have attached a jpg example to give you an idea of what I am trying to create.Would anyone be able to direct me to some tutorial something similar as I can't seem to find anything.
View 1 Repliesi was wondering if theres a way to link the amount and direction of an objects rotation to the mouse position. I want it so if you move the mouse far to the left the object spins fast anticlockwise but if you move it to the center it stops.
View 2 RepliesI recently started creating a small banner with a cog positioned half on the canvas in constant rotation and multiple buttons placed on the cog so they spin on and off the canvas. Unfortunatey at a slow rotation something like 400 frames at 25/sec the cog jitters a lot, even more when more buttons are added.
I was wondering if there was anyway to smooth out the tween for a nice non disruptive rotation and if there is anyway to cause the cog to slow down when hovering over a button.I can make it stop completely on a roll over and start again on a roll out but I was hoping for more of a speed decrease and have never worked with altering this before.
