my problem is that even if the registration point of the MC I want to rotate is in its center it keeps rotating in its upper left corn.The MC is a jpg I load dynamically.The syntax I use is : _root.photo._rotation += 90;

View 1 RepliesI have been working on this and thinking about it for days but I just can't seem to get it right. I want to have a circle that I can "pick up" with the mouse and then rotate (with the rotation point in the center). Currently I have done this with the following code:
PHP Code:
var radians = Math.atan2(mouseY-circle.y, mouseX-circle.x);
var degrees = Math.round((radians*180/Math.PI));
circle.rotation = degrees + 90;
I have added a mouse listener for movement to the circle mc and then checked if a button was down. On button down this code would be executed on enter frame. This code works but the main problem is that I want to be able to "pick the circle up" at any angle and rotate it. If I pick it up with this code the circle automatically rotates to 90 degrees.
All I need to do is rotate an object (which could spawn at any point along each of the four edges of the screen) so that it faces towards the centre of the screen. Obviously this will be done using the .rotationZ property. I will know the starting point of the object, and the centre point of the screen (400, 300). The object begins facing directly 'up' (e.g. if it spawned directly below the centre of the screen it would already be at the correct angle).
View 2 Repliesa movieClip that contains a polygon and some circles at the angles of the polygon. I want to use the circles as rotation handles.Now the code below works but it terribly, terribly slow.I've seen a couple of other examples of rotation using the mouse position, but I want the polygon to rotate via the handle; I think that means the angle of rotation needs to be updated each time the mouse moves.Is there a cleaner/more efficient way to do this?Also, this works only for one direction right now no matter the x/y direction you move the mouse.
public function mouseDownRotate(event:MouseEvent):void {
// get the global x and y of the dragged piece (offset so it looks like it's rotating around the polygon's center

I searched online and found this script that is supposed to rotate and image but I'm not sure how to use, where to put in the degree angle that I want my sprites to rotate by. Also, I get an error. 1084: Syntax error: expecting identifier before leftparen. 1084: Syntax error: expecting rightparen before leftbrace.

I have spent hours trying to figure out how i could rotate a loaded movie through the centre axis rather than the set point set by flash in the left corner.
View 1 RepliesI'm doing a little photo rotation front-end for a site I'm working on. It's a custom photo gallery site that needs to have a photo rotation functionality to it. The back-end developers couldn't find a decent way to do it in Javascript, so they've come to me to figure it out in Flash.They pointed me to the Flickr rotation tool as an example. Seems like it should be straightforward:Load photo into empty movie clip on stageRe-center photo movie clip to the stageUse left/right rotation buttons to rotate image in 90 degree incrementsThat said, I'm having a tough time, after I load a photo into the empty movieclip, using a rotate left and rotate right button to spin the photo around. Obviously, the registration point is in top-left corner of the photo movieclip when the photo is loaded.
I've read that rotation can be managed by putting the clip to be rotated into an outer clip, but...there's a catch......I won't ever know what the exact size of the photo being loaded is going to be, so I can't set the outer clip to a certain size. I only know that it will never be wider than 100px.
I am trying to rotate some points around the center of the circle(0,0), however I'm getting weird values from the output. I've commented the problem code..
Code:
var r:Number = 10;//radius
var y:Number;
var x:Number;
var a:Number = 90;//angle of which the semi-circle is facing.. could be a random angle.
var ax:Number;//rotated points

I am in the midst of finishing up a design application where you can upload images and colors. I use the greensock transform manager. I am taking anything a user does and recording it so I can recreate what they made on larger scale behind the scenes (to be exported for printing purposes)
The problem I am running into is with rotation and moving x and y values. The transform manager does everything relative to a center point, but when i recreate the image object the registration point is at the top left. I have found how to rotate around the center of the object using the transform matrix, but I can't seem to move the x and y correctly because these values change when you rotate. I want to just move the image to the left or right relative to the center. How could I go about doing this.
Here is how I rotate.
private function rotateAroundCenter (ob:*, angleDegrees:Number, ptRotationPoint:Point) {
var m:Matrix=ob.transform.matrix;
m.tx -= ptRotationPoint.x;

i have a triangle that i generate using the following code:
Code: Select allinternal function generateTriangle(w, h, topPoint, color = "0xFF9900") {
var triangle:MovieClip = new MovieClip();
with (triangle.graphics) {
[Code]....
I use this function and a foreach loop to generate 9 differently colored and sized triangles, which works fine when i place them on the canvas. But if i try to rotate them they rotate around the 0,0 point - i want them to rotate around the center of the individual triangles, how do i do that?
1. How do i move a dynamically generated triangle inside a movieclip? Solved using [URL]
2. How do i access each of the triangles inside the movieclip, or even better, place them in 9 different movieclips using addChild so that i can move them around individually?
I have 4 movie clips rotating around a center axis. I know how to make each one pause individually, but I don't know how to get them all to pause when you roll over just one of them. Right now it only pauses the one you roll over and the others continue to rotate. I have this code pasted into the actions of each movieclip that is rotating.
Code:
onClipEvent (load) {
var radius = 220;
var speed = .6;
var xcenter = 450;
var ycenter = 300;

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.
would anyone beable to direct me to a tutorial on how to create a rotating circle menu that is driven by xml.
View 6 RepliesI have a circular diagram with approximately 8 icons around the outter part of the circle. These points are all buttons. When Clicked, I want the diagram and icons to animate round to the top point (360 or 0 degrees). Then, when another icon is clicked they will all move round so that one is at the top.It would be a great bonus to have a slick easing in motion too but not essential - just a 'nice to have'.I have looked over forums and responses and there is quite a bit of info on this but I'm finding it difficult to apply it to this particular project.

I have a rotating dial coded in AS3 but I cannot get it to follow with the mouse - It works the way I want it to if I grab opposite to the pointer (so 90 to 180 degrees from the pointer) to rotate the dial. The problem is that I am using the rotation degrees to set a value only in positive numbers ranging from 0 to 240 instead of 0 to 360. If I change the standard rotation code so it tracks with the mouse, it reveals angles -180 to +180 which would screw up the number conversion to positive 0 to 240. I am thinking if I have to change "var r", then "var tr" needs changing to get it back.
View 4 Replieshow i could make the transition from my last photo to the first photo a more correct transition. maybe my explanation was difficult to understand?? take a look at these two sites(owendawsonphotography.com / owendawsonpga.com) and look at the rotating slide show. when the last image fades out it goes to complete white and the first image comes in at full opacity. I want it to look like the other transitions in the slideshow.

I am a complete and utter newbie when it comes to flash. I've bought Flash Professional CS5, and I am looking for a tutorial/help to create a rotating banner ad similar to the one on [url]...
Example: I've got four different pictures I want to rotate within let's say 3-4 seconds per picture. Each of the picture needs its own link, so people can click to get to the correct place. I want the pictures to "fade out to the left" when changing)
I have a MC that i am moving on to the stage that i want to look as if it rolls in to position. I cant find any referance on how to do this. my code so far is:
//Pic1
PicHolder1.x = 1800;
PicHolder1.y = 322.4;
Tweener.addTween(PicHolder1, {x:161.2,y:322.4, time:1, transition:"linear"});
this gets the motion across but how do i roll it then stop at the end position?
Background info: I am using ActionScript 2.0 and Flash CS5I was working on a game and I used photoshop to save a little gif image. I imported it into flash, "broke it apart", turned it into a movie clip, and put this bit of code on it. It rotates the image when the mouse is moved around it.
Code:
onClipEvent (enterFrame) {
// find x and y differences
