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 )
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;
Has anyone got a bit of code I can use to change the center point DisplayObjects rotate around in a 3D space? I need it to work with rotationX, rotationY and rotationZ. I know theres a workaround of wrapping every object in aother sprite and offsetting the x & y positions but I'd much prefer a math solution. As an example of the problem, this code should make a star shape:

I'm attempting to write a racing game. I've loaded in my image, I brought it to the stage and now, all I want to do is rotate it from its' center and not upper left corner.
The code:
racer.rotation += 5;
rotates from the upper left corner. How do I rotate from the center of the car/sprite? I've tried putting it into a container but I'm unsure on the coordinates of the container because I tried to set the x,y coordinates to half the sprite image but y'know, it's not doing what I expect it to.
ActionScript Code:
if (arrowLeft) {
var container:Sprite = new Sprite();
[Code]....
I will never sneer at another racing game! I didn't think it would be this hard to do a simple rotate of an image!
I have a symbol created out of a bitmap image. When I converted the "bitmap" to a "movieclip" object, I selected the center registration point in the dialog box. After the symbol is created an placed on the stage, I can seen the registration point at the center of the movieclip. Nevertheless, if I check the coordinates of the movieclip, it refers to the top left corner instead of the registration point. The most strange thing is that if I try to check the coordinates of the movieclip using Actionscript - something like trace("x: " + mc._x + "y: " + mc._y); - it do refers to the center point of the movieclip. So how can I have the coordinates during design time the same as during runtime? Why do I always have to refer to the top left corner and not to the ACTUAL registration point?
View 9 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.

function enterFrameHandler(event:Event):void

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 RepliesI have encountered a need to build what amount to classic boardgame spinner.
1. When you click on the spinner it spins clockwise
2. There are several places where it can stop.
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?
[edit] rotation point, aka, registration point.[/edit]
I 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?
I have the following problem. I have an MovieClip in a holder MC. I would like to turn the inner MC X with 'rotation' parameter, and still keep it in the holder mc to the right and bottom of the holder MC reference point. So after turning it should look like thatanyone can tell me how to do that? Basically a function that takes any X rotated in any degrees through X.rotation = ... and puts it back in place in the holder MC.

I want to have arm movement such as the forearm rotating about the arm where the elbow should be the problem is the registration point is at the shoulder for arm. I want the forearms registration to be constantly equal to a simulated registration point where the elbow should be as the arms registration point would be at the shoulder. I need to do it without nesting (a movieclip within another) is it possible. I tried using a constant distant between the two clips but it doesn't work. Don't know I have to use trigonometry or not
I think in brief what I trying to accomplish is
onEnterFrame=function(){
arm._x=shoulder._x
arm._y=shoulder._y
arm._x=simulated_x (where elbow would be)
arm._y=simulated_y (where elbow would be)
}
I am trying to rotate a symbol about the y-axis, 45 degrees one direction, then back to center, then 45 degrees the other direction. Seems like a relatively simple task, except here is what happens.
Here is the object with no rotation:
Here is the object rotated exactly 45 degrees:
And here is the object rotated exactly -45 degrees:
I need the object to rotate the same as it did the first time but in reverse, otherwise "45" and "-45" are generally worthless numbers to refer to. Is it something to do with the pivot point? I made sure the registration point was in the center when I created the symbol. It doesn't seem to be pivoting the object around the center though. How do I rotate about the y-axis using a pivot point that is actually in the center and gives the same (but opposite) effect when rotating it one way versus the other?
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 RepliesI draw a shape,like follows:
var shape1:Shape;

addChild(shape1);
shape1.rotation=50;

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'm trying to convert a Sprite that I have into BitmapData so I can perform some collision detection. There are a few things about the way the Sprites are used that is making this more difficult than I expected:
The Sprite itself is a container which holds another Sprite that actually has a box drawn in it. The inner Sprite is positioned negative half its width & height so that it can be rotated from the center via the container. The container may be rotated at any angle at any given time
So my approach thus far has been attempting to draw the outer Sprite onto a new BitmapData object with a Matrix to account for the difference. Whilst I can use a Matrix to make this work for one particular rotation angle, I cannot find a way to make it work for any rotation.
Here's what I'm doing to draw onto the new BitmapData:
var p:Product = getProduct(); // Product is the container with the inner sprite
var bounds:Rectangle = p.getBounds(stage);
var bd:BitmapData = new BitmapData(bounds.width, bounds.height, true, 0x00FFFFFF);
[Code]....
Translating by the same amount as the previous example will no longer work here, and the box will still be cut off. I've looked around at some solutions posted before or suggestions from other people but they don't seem to work for me due to my container Sprite and rotation.
As 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

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.

What am i doing wrong?
It's been a long time since I've done any work with actionscript, and alas I've forgotten nearly everything. I've tried to look for a tutorial that would explain basic animation with actionscript, but the one that I found on Kirupa was no longer there.
Basically I'd like to do this:On the stage I have a movieclip and I'd like the movieclip to move along the x-axis to a certain point and then back to the starting point again. The moving speed of the movieclip should also be adjustable.
I'm creating a game in flash for a university project, and learning actionscript and programming as I go. I'm very much still at a beginner level - at the moment al I have is some actionscript for drawing rectangles and moving them about the screen. This is what I'm having trouble with at the moment: I have a class called 'Creature', and I want instances of it to interact with each other. I want them to do something when they come within a certain distance of another instance. And I want them to be able to pick a random other instance to get the location of, in order to do something with that information.
What I think I need is: A function for telling the distance between two (x,y) points.
A way of referencing the nearest other instance of the class. And a way of randomly selecting from all of the instances of the class.
How to convert 3d point to 2d point? I've found next formula in Internet(camera is situated in origin)

But these formulae give me strange result when z are less than zero(z<0) I need build line from A(100,100,100) to B (100,100;-100) As you can see these equations give really strange result when I try to convert B point in 2D dimension
I am using AS2 with Flash 8 Professional So, my problem is that I currently have a man in the middle of the screen, who shoots a line towards the mouse when I click. However, when I use hitTest to see if the line collides with another object, Flash recognizes the line as a large box if it is diagonal, so the hitTest isn't very accurate. The line only satys there for one frame, so I can't have the usual moving-bullet-style. I am either looking for a way to create an imaginary line with AS from the starting point to the mouse and beyond, and tell whether or not this line intersects with an object... or some other way that I haven't thought of to fix my problem. Keep in mind that the line rotates from a center point towards anywhere around it for 360 degrees.
