how I can count the B point's coordinates (see attached image... or not as I am a new user...pf!). I know the arrow's rotation - so the angle (let's say it is -120), A's coordinates (0, 0) - A is the middle point of the arrow, and that the distance between A and B is 50 px.

I know some basic trig. but how do i find an angle from an anchor point and a moving point?
adjecent = _root.anchor._x-_root._xmouse;
opposite = _root.anchor._y-_root._ymouse;
hypotenuse = ((adjacent ^ 2)+(opposite ^ 2)) ^ 0.5;
i have the follow issue :
I have a point which is setted at the border on a component, with changed transform point to the center of a component in order to match the component rotation.
the important part is when i try to get the point XY after rotation - they remains the same as before rotation.
how to get XY, after rotation ( changeing point.rotation property to specific degrees of rotaion )
How do you determine the "rotation point" (axis?) of an object?
A sprite/movieclip that has been loaded using a Loader has its rotation point set to the upper-left corner. What I want to know if how I manually (using ActionScript) set it to the center.
I know 3D rotation is well documented on SO and many other sites, but despite reading countless explanations I still haven't figured out where I'm going wrong. My background is in art and design, not math and programming, and I'm never really certain if my angle of attack (no pun intended) is the right one. Rather than paste a patchwork of my dismal code, I'm including an image describing my problem. What I'd really like is a step-by-step worded breakdown of how to solve it. Pseudo code is useful, but I will learn more if someone will just aim me in the right direction or point out common pitfalls.

I have 2 objects on stage, pane (which rotates) and topbut (which initiates the rotation) Currently onRollOver of topbut rotates pane indefinitely, what I'd like it to do is stop once the rotation has gone through 180 degrees.

I'm working on an interactive animation for a university assignment. Here in this scene the user is able to turn a safe dial left and right either using on screen buttons or keyboard keys. The trouble I'm having is trying to write an IF statement to detect the angle of the safe dial so when the dial == an angle of rotation the scene goes on to play the next frame of the animation.
Code:
import flash.events.MouseEvent;
import flash.events.KeyboardEvent;

I have a stage with and height of :600x400 On this stage i have 3 squares that have a centerpoint in the middle. The square are 90 (width) and 80 (height)The first square is aligned to the left site and the second one in the middle and the third one on the right The perspectiveProjection is setup using the middle of the stage as it projectionCenter.When i rotate all squares to 90 degrees (rotationY) than only the middle one is now not visible anymore, at that point i want to switch the image inside the square. But at 90 degrees the left and right squares are not invisible.. For the left square that point wouldbe at 90 - 22, and the right one 90 + 22. Is there a way to calculate the correction value (22) in this example?
What i don't want is to give every square it's own perspectiveProjecten , then it would work but you have a completely different3D rotation.The only thing that goes wrong in my example is that the image from the left and right square are not changed at the right time, because 90 degrees on the left square does not mean it it not visible at that point.
And here is the code:
import flash.display.MovieClip;import flash.geom.Point;import flash.geom.PerspectiveProjection;import fl.transitions.*;import fl.transitions.easing.*
var squares:Array = [c1, c2, c3];

I need to move a movieclip dynamically over a path. The movieclip has a front which should remain pointing to front when moving along the path. So I need an angle at which the movieclip should be rotated regularly. This is something similar to the motion guide we have in Flash.
View 5 RepliesI have a rotation value in degrees(0-360) and a value for magnitude, ie (1-10 pixels per second).
How to apply this information to determine what to add to an objects x and y values to send the object off in a given direction at a given speed ?
I'm trying to parse some simple XML and use it to render some controls, its all going so well. I'm having some trouble with E4X and counting the number of nested nodes within a certain child...code is as follows....
Code:
<questions>
<question>
<label>History of Smoking</label>
<value>3</value>

The Alert keeps coming up as 1. I read in the documentation that this will happen with XML objects but it is working when I create the XMLList and counts the number of questions I have. The code is working except it is only rendering 1 RadioButton, very sad. I suppose I could put the number of options within the <options> tag but I'd rather do it dynamically to avoid errors.
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 not a genius in geometry, I'd like to find a point in as3 with the radius and a angle but I don't remember the rule, I know this should be simple!
View 3 RepliesI am looking for a way to find a vector if I know one point and 1 angle. Like I have A(x, y) and a vector starting from A(x, y) with an angle. I would like to know the position on a point X (x, y) that can be anywhere on that vector. I only know the coordinates of A and the angle. Possible?? I guess it has to be a function...
View 5 RepliesI have a set of links (movie clips) arranged in a circle. When one of the links is clicked, I would like the circle of links to rotate until the selected link is in a certain position - straight down (90 degrees) in this case - and the others to maintain their positions relative to the clicked link (ie: they all move, but the distance between them is maintained). The behavior is intended to be like a bullet rotating into a chamber on a revolver, or - more accurately - like that of a Ferris Wheel.

// setting variables
var centerX = Stage.width/2; // Stage Center X

I have a slider which I want to use to rotate an image around it's center. This normally is easy but my problem is the clip is made dynamically and the size changes so I can't use the default registration point and I need to assign the center point before I rotate it. I found the rotateAroundExternalPoint function which rotates around a center point fine. How to get it to rotate to a certain angle and then have it stop at that angle. The rotateAroundExternalPoint increments the rotation rather then allowing me to set the angle to rotate to. Is there anyway that I can set what angle to rotate my clip to? It right now increments the rotation by the x coordinate of my slider bar (slider_position.x).
Code:
import flash.geom.Matrix;
import fl.motion.*;
var mat:Matrix = clip.transform.matrix;
addEventListener(Event.ENTER_FRAME,EnterFrame3);
function EnterFrame3(event:Event) {
var center_point_x = clip.height / 2
var center_point_y = clip.width / 2 //
MatrixTransformer.rotateAroundExternalPoint(mat,center_point_x,center_point_y,slider_position.x);
clip.transform.matrix = mat;
}
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.

Flash uses a movie clip's REGISTRATION POINT to determine the MC's X and Y coordinates, correct? If not, what is used?
View 4 RepliesSo let's begin. I want to build a wheel which you can spin, similar to a roulette wheel. You can do this both ways (CW and CCW, this issue causing the bug, actually). The wheel has some acceleration to it too, and I achieve this by measuring the start and final angle of the drag movement, using Math.atan2(dy, dx). The problem is the following: atan2 outputs the following angle scheme, assuming the point relative to which the math is done is in the center of the circle.
atan2 returns a value measured in radians, so I'm using the classic angle*180/Math.PI formula. I've changed this original scheme into the following, using some simple math to shift the angles a bit, to resemble more accurate circle angles (going up to 360 degrees) The problem that I'm facing at the moment is should the user decide he wants to swipe clockwise, and moves through the right point, where 0 turns into 360 or 180 turns into -180, the whole angle difference thing is capsized. It registers a CCW movement (as if the user swiped his mouse all around the circle). So, I'm looking for some ideas as to how I can work around this small issue.
From Pro Adobe flash can I export an animation's data? like the x and y coordinates and rotation values for individual images in a sequence
View 1 RepliesI have two point p1 and p2 and I want to designate coordinates of the point that is exactly between them. So I used the Point.distance method to designate the distance between them but I don't know what to do next to achieve my goal.
View 3 RepliesFlash knows where the anchor point is in 3D space in order for the symbol to rotate around it, but I can't seem to figure out how to see the coordinates of the anchor point or type in new ones. Please tell me how to do this. I am already very annoyed that Lynda, a pay service, doesn't think this is vital information. Apparently they think we would never want to do anything more visually stimulating than one simple spinning logo! But I digress...
Just to be clear, I know how to move the anchor point visually on the stage, but I want accuracy. I want to be able to give two symbols the exact same coordinates to rotate around.

View 9 RepliesI have encountered a need to build what amount to classic boardgame spinner.
1. When you click on the spinner it spins clockwise

When the user clicks the spinner I run a method to determine where (what target) it should stop on.
How can I make the spinner spin a few times, decrease in speed (ease) then stop at a certain angle?
i'm working on a flash game at the moment, and i would like to know if i am able to set the point that the movieclip rotates around using actionscript.
i don't want to do it by simply moving all of the contents of the movieclip closer or nearer. is there any other way of doing it? i couldn't find any simple functions for it. am i just going to have to use some complicated maths?
