ActionScript 1/2 :: Passing Coordinates Relative To Stage Into A Nested MC?
Jul 8, 2009
I am building a project where I have 15 'islands' inside one big 'ocean' movie clip. I created navigation buttons so you can explore the Ocean movie clip and look around the islands. my problem comes when i want to 'zoom into an island'
So basically on the stage i have a movie clip called- Ocean_mc, and inside it are 15 movie clips, one of them (for this example) is a movie clip called GreenIsland_mc.
when a user clicks the GreenIsland_mc it needs to expand and place itself centre stage, then when clicked again in needs to colaps back to where it came from. The problem is that when GreenIsland_mc expands it needs to expand to coordinates relative to the stage, but when I shrink it back again it need to find the original coordinates relative to its place inside the Ocean_mc movie clip.
I've a button on the stage called "closedbt" that i have to move near an image. This image is nested into a MC named "gallery", then it's coordinates are different from the rest of the stage.
I am new to Flash and ActionScript 3.0 environment. I don't have any knowledge in depth with Flash and ActionScript 3.0. I am using the flash(.swf file) in my Java application. Now, this .swf file is to be placed in the server system. While I am working with these, I faced an error. Here, my issue/problem(s) starts....
1.)With the help of URLRequest & URLLoader classes, I am loading a jpg file dynamically onto the stage using the following code:
I have a movieClip inside a parent movieClip on the stage. The parent movieClip's registration point is top left. I'm having trouble figuring out how to "center" (move) the parent movieClip so that it's child movieClip is in the center of the stage. How do I calculate those destination coordinates?
I am creating a film strip of thumbnails and am dynamically creating the thumbnails from an xml file. All this works great. The issue becomes the fact that I need for the filmstrip to resize when the window is resized and add or remove the number of the thumbnails as necessary. In order to calculate where the last thumbnail should be, I'm using the following code to calculate the x position:
PHP Code:
var lastX = rightArrow.x - (thumbWidth + 10);
where rightArrow is actually filmstrip.filmnav.rightArrow. I get the correct answer - but when I add the thumbnail to the movieclip filmstrip.panelscontainer.thumbcontainer, it's actually on top of the rightArrow. Clicking on both of them to see where Flash thinks the X is will show that Flash this the X of the thumbnail is at 607 and flash thinks the X of the thumbnail is 731, which is as it should be -- so why is the thumbnail so far to the right?The first thumbnail should always be x=10 and that is working fine and I'm currently not trying to layout the other thumbnails because they were all screwed up with a similar problem.
I have a main mc, with another mc nested inside it that needs to reposition to exact x,y coordinates (on four separate occasions). Can I put keyframes on the timeline with a script placed on the keyframes so that when my main movie reaches those frames, the nested mc repositions to the specified coordinates?
I am trying to get a movie clip - nested inside another movie clip on the stage - to match the x, y coordinates of the mouse. Attached is an example file both in Flash 8 and MX2004 formats. I can get the drag to occur, but the problem is that the dragged mc's coordinates are relative to it's parent movie clip and not the stage. I have been messing around with localToGlobal with not much luck. I think I may be using it wrong, though. I have left it out of the example file.
Here is the relevant code: var dragging = false; this.onMouseMove = function() { if (dragging == true) { this.container.drag._x = _xmouse; this.container.drag._y = _ymouse; }}; [Code] .....
I have a MovieClip ("mc3" that moves dynamically) inside of a MovieClip ("mc2" that moves dynamically) that is on the stage ("stage" that is static). I need to find the value of mc3's x in relation to the stage? I need to make it into a variable. I am trying to do the math, can't figure it out. Also tried localToGlobal and failed.
Code: class Test{ public function set movePlayer(_Playah:MovieClip):Void { trace(_Playah._x);
[Code]....
and when I "run" this function in my .fla file, its says "undefined" (for this position) how to "pass" MC informations to a function inside a class (x,y coordinates, rotation..) although when I trace only "_Playah" it shows the correct name of MC i've passed to it.
how to proportionally scale multiple movieClips relative to the stage size.
I understand movieclip placement relative to the stage, and I have been using a code to scale MovieClips as a fullscreen background (also proportionally)
But
I can not figure out for the life of me how to scale other movieclips in relation to the stage size.
for example I have a background_mc that proportionally scales with the stage to fill without distortion.
HOW do I then place another MC say center aligned (I know how to do that) that will scale with the background without distortion?
Ideally I would like to place several MC's on my stage all scaling in proportion with the stage yet independently.
I have not been able to find any documentation on this. lots of tutorials on backgrounds and color fills and the like but nothing on proportional scaling of independent mc's
this is the code I use for my background_mc (can it be modified or should it be thrown out the window to achieve independent scaling?)
My main SWF file, "working_login.swf" has a movieclip that loads another SWF file, called "membership.swf". It loads this SWF file inside of a movie clip which, upon a press of a button, tweens the movie clip containing the "membership.swf" onto the screen. Membership.swf allows you to login using "testing" as the user, and "testing" as the password. I have no idea how to dynamically change the username_txt dynamic text on the main swf.
What I want: I want it to display "Hello, guest!" when there is noone logged in and no cookie set. I want the program, upon someone logging in as "testing" to have the dynamic text box display "Hello, testing!" upon a successful login. Right now, I have absolutely no idea how to go about this. I am using a class to set the dynamic text, but I cannot figure out for the life of me how to set it up to recognize a guest VS someone logged in. These are the following files that I am using: [URL]

I'm developing my first flash app. I'm trying to use classes because they'll be very important in my future app. I created a simple movieclip with a star. However, instead of putting it directly on the stage, I'm calling it from library, using the addChild method to place the star in the stage. To do that, I simple right click over the movieclip icon->properties->check export to action script->and I give a name to the class (for example: myMC)
Then, inside the class I wrote: package { import flash.display.*; import flash.events.*; public class myMC extends MovieClip { var star:myMC=new myMC(); public function myMC() { [Code] .....
As I am placing the two variables origin_x and origin_y inside the constructor, I'm expecting to get 250 and 200 respectively. After drop the star, I want to send it to it's original place, and that's why I need to keep this values. And here's the problem, origin_x and origin_y are both ZERO, instead of 250 and 200... The value is not relative to stage. I managed a little bit and I found this post : [URL]. Unfortunately I tried to replace by the suggested code, but both values remain zero. An interesting thing, is that if I put the star directly in the stage instead of calling it from the library as I am doing, I get correct values in origin_x and origin_y.
I have a Flash file for an xml driven menu. There is the document Class, called Main. There is also a Navigation class. In the Navigation class, I position the location of main buttons and sub menu buttons for the menu. I want to position the buttons in the Navigation class relative to the stage. Currently, they are just fixed at certain positions (like 20); To do this, I have read that because this is not happening in the document class.
I must add an event listener to the constructor that listens for the added to stage event. I am not sure how to do this, as when I try and add an event listener for added to stage in the Navigation class nothing happens, (or all menu items diaspear). How to position movie clips relative to the stage (i.e. stage.stageWidth - 50) from a class that is not document class? How to do so in the document class, too.

I was wondering how "relative alignment" such as on the easybit-site (take the window and resize it) is done? All objects on the stage are positioned always relative to the actual window-size without losing quality, but how???
I made a spinning globe with Away 3D which sits in front of a 2D graphic in a specific spot. The swf is going to exist as part of a web-page. When a user hits "zoom in" or "zoom out" on there browser (looked at FF and IE) and refreshes the page, the 2D graphic is zoomed and stretched. The spinning globe is also magnified, but falls out of position... in this case, down and to the right. I put my original re-jiggering steps to put the globe in place in an onResize() method, called by stage.addEventListener(Event.RESIZE, onResize);
[Code]....
Even if I wanted the globe to stay dead center on the stage, I don't know how to do this. What kind of calculation do I need to make in my onResize() method? Do I move the view or do I need to move something else? Can someone explain what is happening to the viewport or the camera when the stage is resized?
All though I can scale down the size of my objects and can shift them to their correct positions when scaling. I cannot shift them to the correct relative positions, relative to the screen centre.
Code: level=1; //starting scale level public function scaleOut(level:int) // scale to a level 1-4{ for (var r = 0; r < Main.ballArray.length; ++r){ // scale radius Main.ballArray[r].bRadius *= (oldLevel / level); [Code] .....
I have a whole stack of tile instances arranged in a grid on the stage. Each mc has a button in it. All I want is when the user clicks the 'mc', to return the coordinates of that mc relative to the main stage. I've tried _root, _parent ... everything.
Does each tile have to be named? Of course I have been able to find the coordinate if I name them all but I'm dealing with about 600 of them. Also, they are arranged in a weird way that I can't use AS to generate it at runtime. Check out the attachment and you will see what I mean.
I know about Flash's localToGlobal and globalToLocal methods to transform coordinates from the local system to the global system, but is there a way to achieve the intermediate? To transform coordinates from an arbitrary system to any other arbitrary system?
I have a clickable object inside a Sprite, and the Sprite is a child of the stage. I want to retrieve the clicked point in the Sprite.
I have a graphical component and I am trying to obtain it's coordinates relative to the stage by using the localToGlobal or contentToGlobal methods.
My problem is when scrolling a Container, these methods do not return the correct values, but return the old unshifted coordinates of the graphical component. Later, after everything seems stable, when trying to use the methods they return correct value so this means at the time where I use them after scrolling not all information necessary in computing have been commited.
For the case of the Container class I have investigated and although it passes through the scrollChildren method, the computation is wrong.For the case of the Tree component when scrolling with the wheel, the methods return correct value, but when pressing the arrow button of the scroll-bar the methods return incorrect value.
Until now I have tried to listen the scroll and the update complete events when they are dispatched but without any success. So my problem is that after scrolling I would need to know a moment(event to be listened or something else) that I can call the methods and the output to be ok.I would like the final solution to be uniform.
