Actionscript 3.0 :: Dynamically Generated Objects Rotating Around Its Own Center?
May 12, 2009
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?

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).

I have created an empty movie clip in the root, I load dynamically some jpg to the empty movie clip, but now I want to center it and I can't I have this code, it centers the movie clip but on the registration point of 0,0 not in the middle of the movie clip so the movie clip will show up nice and centered.
ActionScript Code:
var stageL:Object = new Object ();
stageL.onResize = function () {

I'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.

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;

I 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.

a 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.
var point:Point=new Point(spr_box.x+spr_box.width/2, spr_box.y+spr_box.height/2);

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 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;

ok, here's the deal. We are creating an ecard that will be customized by the sender, and sent to soldiers in Iraq. There are about 5 different things that the sender can customize, as well as write a message. The goal is to have their choices sent to a database and then inserting those variables when the receiver watches the movie.Now, instead of creating possibly thousands of XML files (one for each sender), we decided it would be better to just generate the XML on the fly from the info in the db. But my question is, how do I handle loading that XML? Since this won't just be a static page on the server, I'm not sure how to go about it. I'm wondering if you can use variables when loading XML, for example:
Code:my_xml.load("senderData.xml?user=LyndaSmith");Basically, how can i create an XML file on the fly with the values from the DB, that can then be loaded into Flash?I have virtually no experience with db's, so this is the method I came up with because I do have some experience with XML. I have a developer who will actually insert the values into the database with ColdFusion, and he can also generate the XML, I just need to be able to load the dynamic XML in flash when the receiver watches the card.

I have a movieclip that I am adding to the stage dynamically. The movieclip has to be placed at specific coordinates to match the current text field.The coordinates that show on the INFO tab are x=264 and y= 365. However, in order to get the movieClip to match those I have to set x to 398 and y to 200.If I set the coordinates to those in the INFO tab then the movieclip does not show; it appears off stage.

My company has a database-driven system of web forms, each ofwhich consists of many questions in various layouts (2-columnradio, 1 column checkbox, etc). The forms are never hard-coded.Each HTTP request causes Java code to perform DB queries todynamically generate the various questions and answers.Thosequestions are then rendered through JSP and Struts tiles into HTML.The HTML also contains JavaScript functions to hide/showconditional questions on the web page based on answers to earlierquestions. Now we're trying to figure out the best way to adapt thissystem to use a Flash front-end instead of HTML/JavaScript.My preliminary research suggests at least two possibleapproaches:
1. A pre-compiled SWF could send a request with certainparameters, and the server could respond with an XML description ofthe form to build. Then the SWF could parse that XML andynamically generate the form using attachMovie for each formelement (with a lot of math to determine relative positions ofelements with variable sizes, like text labels). 2. Flex might reduce the code for placing elements, by usingMXML to describe the form structure as well as visual arrangement.I haven't used this yet, and I'm wary of Flex 2 simply because itrequires Flash Player 9 which is only at 50% browser penetration

I'm currently reading in data from an XML file. Each attribute of a child is assigned as a property of a movieclip as shown in the code attached. However, what i'd like to do is not have the property names already decided as i don't necessarily know how many attributes a child in the xml file will have. Is it possible to dynamically name the properties depending on what number attribute they are...?

I've tried to generate movieclips dynamically the method I have used does the following:
Uses a loop runs depending on how many movieclips I want to generate e
Each time the loop cycles it creating a new movieclip instance
Adds the new movieclip to an array
Uses method addChild to put moveclip on the stage then draws a rectangle
begins fill
ends fill
Adds it to that movieclip
I then use a conditional statement checking if the movieclip is the first item in the array if so it sets the current MovieClips x and y position to a chosen value. the first movieclip is used for a starting point to align the rest of the generated movieclips to. If not the movieclips x and y position are set to the previous array items x and y position + current movieclips width or height + the gap I would like them to have. Then the cycle repeats. I've coded this using timeline code and it works fine the shapes appear on the stage no errors. I tried to move this code off the timeline to an as file and the code has no errors but when run I just don't see the objects even if I trace there x and y positions I don't see them on the stage.
Timeline Code
var mcArray:Array = new Array();// DEFINE ARRAY FIRST
var randomNo:Number;
var colorStr:String;
var currentColor;
var movieClip:MovieClip;// TEMPORARY VARIABLE

I have a Flex application which references a separate MXML file as a template for a custom component. I create instances of the component dynamically several times in my program, but I need to get a handle that will allow me to modify that instance of the component as desired. I pass specific information to this component on instantiation using bindable public variables in the component's MXML file. I add it to my main program using addChild().
I want to update the component's progressbar as necessary and I want to remove it from the box to which I addChild'd it. What's the easiest/best way to get a variable that will give me predictable access to each component so I can easily manipulate the components as necessary? Some research suggests creationComplete, but I decided it was faster to just ask than to go through lots of different experiments and come up blank.

I'm not quite sure how to describe the problem I'm having but I'll do my best. I have an image gallery built in AS3 that loads content via an XML file. Nothing mind blowing here... When testing locally on a static XML file, the gallery works as intended. The purpose of this gallery is to function within a CMS and load dynamically generated XML files to display the appropriate images/info for each particular gallery. All this functions fine, to an extent...

The first part works, I can "firstText" and I can make it go to frame 9 and stop but I can't manipulate the movie clip "title_txt" which is inside "firstText"

So basically my file is a photo gallery. There are two ways to click through the photos - the previous/next buttons or the camera icons on the floor plan diagram. The cameras are dynamically generated from XML, into a cameraHolder mc.
I have the controls working independently, but I need to have them working together (ie: if you click the previous/next buttons, the camera icons would change state) I don't have all the over/selected/visited states working yet, but I don't really need help with that.
What I really need to be able to do is figure out how to call the camera icon clips. See line 138 for where I tried to trace one: trace(cameraHolder.camera0); It returns as undefined.?
Also is is possible to call a mc where part of the name is a variable? For example, you'd call something like "camera" + whoIsOn instead of camera0?
FYI: this file is definitely a work in progress. I kind of slapped together two examples to get what I currently have...
