url...I'm using this code i made some changes like changing the array for a xml.In some part i put a button to stop the movement and i used [code]
and it works perfectly, but then i want to return with another button to the movement. and i can't make it work.
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 Replies[URL]I'm using this code and I made some changes like freezing the rotation when the mouse is over the rotation entities. But I'd like to stop rotation when the mouse leaves the stage. How can I do?This is my code

import flash.filters.BlurFilter;
import mx.transitions.Tween;
import mx.transitions.easing.*;

find greatest common factor and lowest common multiple
View 8 RepliesAs 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 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.
onEnterFrame=null, onEnterFrame=undefined & delete onEnterFrame....
Which one to use??? What are the performance considerations. If all my movieclips on-stage are running a MovieClip.prototype.onEnterFrame = function() {run initial stuff before setting onEnterFrame=null/undefined... }, will there be performance hits? It's sad that delete onEnterFrame doesn't work unless I delete the prototype enterFrame as well, which would make the clips reinitailise itself again once you declare the enterFrame prototype again (i need to do this since there's more movieclips that end up appearing on-stage, and they need to automatically initialises themselves the moment they appear).

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);
function rotateAroundCenter (ob:*, angleDegrees) {
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 {
ball_mc.rotation = getAngle(ball_mc.x, ball_mc.y, mouseX, mouseY) -90;
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 3 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);

Why isn't there the Z, rotation X and rotation Y fields in my motion editor panel?

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.

Simple question: In AS3 you can't do sharing of a MC between more MCs, right? In AS2, you can. How can I work around this?
Let me be specific: in ActionScript *TWO* I do something like this:
movie.attachMovie(LargeImage, "image", 20);
LargeImage = movie clip of 400 x 480.
Now... the thing is: I do this for 20 MovieClips but they all REUSE the same original MC apparently (with no memory increase, of course). If I animate the MC, it will animate within all 20 MovieClips. I'm using a mask to show only portions of the MC, but I think that's not important.
But in ActionScript 3 this wouldn't work, right?
Because in AS3 every time we .addChild, the child is REMOVED from the parent, so the same MovieClip / Sprite couldn't be in 2 places at once. How would you work around this without creating a separate instance of the "LargeImage" MovieClip for each object? Note that I don't want to use BitmapData & CopyPixels: the object may be animated.

View 1 RepliesWe are working on a project where we have multiple modules- all these share a common set of functions like rounding, string parsing etc.Currently, we have added these functions into the parent container (which calls these modules) and use them in the respective modules. Likewise, if we have to share variables between modules, we add them to the parent module- so it becomes shareable across.Is this the right approach- both from a performance and structure perspective?
