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.
View 6 RepliesI 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 RepliesOne of the strangest things I've EVER seen with any software. I teach Animation at a high school. I had my students do the following, using Flash CS4, on Windows XP SP3, with Flash 10 installed. All software latest as of April 2010.

I have a project on the go which has a compass that I would like to have move randomly around a fixed central point (giving the idea of changing direction).Would anyone be able to help me out with the coding to get this to work?
View 1 RepliesAs in the figure i have three lines out of which line1 and line2 are fixed. line3 is derived from line1 based on some angle say 70.I try to rotate the line3 but it deviate from the point x1 and x2. I try the code like this

I nedd to build a "See if you have the right weight" wheel in Flash. It have to be a small wheel over a bigger one. The top one have to be drag and drop like it was pined to the other one, so it rotates around the center axis (when click and drag with the mouse over), allowing us to match the scales in the wheels as we like.
I've found a lot of tuturials about drag and drop objects in Flash, but freely, not around a fixed center axis.
I'm trying to pause my rotation on rollover of a movieclip and restart rotation on rollout of the movieclip. Here is my current code,

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);

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.
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);
}
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]

I draw a shape,like follows:
var shape1:Shape;
shape1=draw();
addChild(shape1);
shape1.rotation=50;
[Code]....
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 posted a while back looking for a function to make one movieClip circle around a fixed point. The solution I was given (which has worked perfectly up until now) is:[code]This function is called repeatedly by a Timer (loopTimer) with delay 10.The problem I have hit now though, is that if I want to modify or reverse the speed of rotation at any point it causes a jump in position (because I am setting the x and y values directly, rather than incrementing them e.g. "x = ..." rather than "x += ..."). Can anyone see a way to modify this function so that I can just increment the x/y positions?
View 5 RepliesI have a library symbol, exported for Action-Script and to Frame1. Now in the document Class, i write

Now the code works fine but when i write my own (sealed/fixed) Box Class that surely Extends MOVIE-CLIP, statement-2 gives error , i know the Box Class is not dynamic but the Movie-Clip is Dynamic. Now what i understand that Movie-Clip Class being dynamic becomes fixed/sealed when it is extended by any Fixed/sealed Class???
So I've found numerous tutorials on rotating to face the mouse, and none of the rotation equations work properly for me. I made my own that worked but then it just over complicated things such as bullet direction.
Code:
var radians:Number =Math.atan2(mouseY-ME.y,mouseX-ME.x)
var degrees:Number = (radians/Math.PI)*180;
ME.rotation=degrees;
That is the only code that changes the rotation of my movieclip. and it always seems to be about 45 degrees behind my mouse?
Basically, what I'm trying to accomplish is moving a movieclip towards the direction it's facing.I've been scoping around the net for different ideas on how to do it, but I've only found AS2 tuts.
What I've done already is making the movieclip rotate around it's own center when the user presses either the left or the right arrow-key.What I'm now trying to accomplish is to make the movieclip move forward to the direction it is currently facing when the user presses up and vice versa for pressing down.
How to MovieClip rotation with acceleration?
View 2 RepliesI need to put rotation handles to a movieclip. The same way it happens when you rotate an element in editing mode but in the final movie.
View 3 RepliesI am making a 'simple' template builder in flash which allows the user to add/remove text boxes and images to the stage.
I can rotate any of the movieClips fine but it rotates from the top left and i want it to rotate from midpoint. Is there a way to set the midpoint/rotation point using actionscript?

View 3 RepliesWhat do I have to write to keep the movieclip not to change dimensions if the user starts playing with the dimensions of his screen ? I remember it was a line of as3 written at the beginning.
View 3 RepliesI've a movieclip representing an arrow (with registration point in its middle). When I click a button, the arrow must point to a certain movieclip on stage. I use this code to execute the Tween:
TweenLite.to(arrow_clip,1,{rotation:degrees});
But I can't understand how to calculate the degrees. I tried the following with no luck:
var degrees =Math.atan2((clip.y-arrow_clip.y),(clip.x-arrow_clip.x))*(180/Math.PI);
I found the following is working but I can't completely understand why:
var degrees = -(Math.atan2(arrow_clip.x-clip.x, arrow_clip.y-clip.y))*(180/Math.PI);
How could I do: To attach a movieclip (e.g. 'footsteps'), along a path (other movieclip).
That would be within a interval for attaching one movieclip at a time.
I would need rotation, i.e, the footsteps, should rotate according with the path direction.
I'm having a problem with a little movement script I wrote for a MC I have. I believe it either has to do with variable scoping, or with a coordinate system problem. (If I change the xPos and yPos in the onClipEvent (load) to 0,0...then the MC starts in the middle of the field (MC) I'm trying to move it inside of.) Basically...the ActionScript you see below is a part of the "Player" MC...who is supposed to move around a "field" MC I have.
(I was assuming setting xPos and yPos to 0 would have the Player MC starting at the very top left of the entire screen...which instead it starts in the middle of the "field" MC.) Also - When I press the different arrow keys...the Player MC jumps around to different locations...but once at the new location the movement (in a single direction) works okay. I've attached the .swf.
onClipEvent (load) {
speed = 2;
xPos = 0;
yPos = 0;
this._x = xPos;
this._y = yPos;
