Actionscript 3 :: Set Zoom On Mouse Click Target To Center Of Stage?
Aug 24, 2011
I'm having toruble with an image that I zoom into in flash. I got everything to work, only I want the clicked X and Y coordinats to center to the stage. ( so that the area clicked on always zooms in and position the area clicked to the middle of the stage) the image is a movieclip and it zooms with a tween, but i tried everything but the image wont center the stage..
does anyone have a clue for wich actionscript 3 code I can use to do this?
my code is:
const TWEEN_IN:String = "tweenIn";
const TWEEN_OUT:String = "tweenOut";
var tweenDirection:String;
[Code]....

I have a big movieClip which the user can zoom by click on a 'zoom-in' button. Once zoomed the user can click on that movieclip and pan it. Now the center of that movieClip is displaced and no longer where it was before. However, if the user click on 'zoom-in' now again, the movieClip should zoom from the center of the stage and not from the movieClip's center.
To put it simply, I want a formula which will zoom a movieClip from the center of the stage and not from its registration point, no matter where the registration point is.

Is there a way on a drag zoom image viewer to have the draggable mc scale from the center of the stage rather than from its registration point?

up/down/right/left) except for zooming around the center of thestage. Let me explain, the user can drag the map in any directionany number of times but whenever they zoom in/out whichever pointof the map is in the center of the viewable area should always stayin the center.So for example I have several zones in my map, like Zone 1,Zone 2, Zone 3, etc. Let's say the user wanted to examine Zone 1more closely so they move the map in such a way that Zone1 nowappears in the center of the viewable area. I want when they zoomin/out Zone 1 to always remain in the center.
So I have the Map as a movie clip symbol and as a buttonsymbol. In Scene 1 of my Flash document I've inserted the Map movieclip and inside of the movie clip I have the Map button. In Frame 1of the layer where my map is I have the code for moving and zoomingin/out. Here is what it looks like below.

I'm developing a full screen zoom/pan UI. Everything is working great, except I can't get it to center on the correct point when zooming in.
You can view what I have here: [URL]
The numbers in the top-left corner are the navigation, and the white boxes represent the individual sections.
I have a large container movieclip that fills the entire page. Inside of that movieclip (site) I have all of my individual section movieclips (section1-section6). I'm also using a dynamic registration point class to dynamically set the registration point of the "site" movieclip to the current selected section, so that the zoom in/out is centered on that section.
When a user clicks on a navigation item, I first reduce the _xscale and _yscale of "site" to 80, when that is complete I move _x and _y to the position of the selected section's movieclip. When that is complete, I set the _xscale and _yscale back to 100. Right now, it is not zooming in centered, so I have a final step where I correct the _x and _y position after zooming back in.
If I don't zoom in/out I can successfully pan the movieclip and center on the correct section. I believe the problem is that I am moving the _x and _y to the position of the "site" movieclip as if it is at 100%, but since it is at 80% it is not moving to the correct position. I tried to fix this by giving the _x and _y coordinates as:
endX = endX / 100 * 80;
Which made it a little better, but still not centered. I have a feeling that there may be a fundamental flaw in my approach to this.
For some reason the forum won't let me attach my .zip, so I posted it online, as well: [URL]
My code below, in case you don't want to download the file:
Code:
tile._alpha = 0;
currentSection = section1;
//** Set Stage **//

I have a slider which increases and decreases the scale of the map area, however, I cannot work out how to make the area being zoomed into stay in the centre of the map.I have attached an example file to highlight the problem. If the red dots are lined up and the slider moved I want the red dot on the map area to stay in the same place and not move as the map grows.

I want to program something that does this but I have no idea how to get started or whether it is possible.
1. Using the loader class I will load several images to the stage and set their x / y coordinates accordingly so that they don't overlap.
2. A random x, y coordinate is generated within the document class.
3. If there are any loaders that exist at that location it will be deleted.
If the x, y coordinate was to be generated by a click to the stage, I could do it like this.
Code:
// detect for clicks at the stage level
stage.addEventListener(MouseEvent.CLICK, dosomething);
public function dosomething(e:Event) : void
[Code]....
But I want to be able to send a simulated click instead at a certain x y coordinate, and then use the .target to operate on the object that it refers to. Is this possible?

When I zoom out, instead of centering the document on my zoom, it pushes the doc to the upper left corner. It is pretty maddening, as I am zooming in and out a lot.
Is there a way to manually center the artboard?

I have a movie clip of all counties in the state of Montana (allcnt_mc). Within allcnt_mc there are individual movie clips specific to each county with name equal to the county's name. When clicking on a county, I'd like to zoom to that county and center the stage on it. I've added event listeners to all counties through querying an xml table that has demographic info I am calling into dynamic text boxes. Here is the code I have thus far to load the xml and add the listeners to the county movie clips.
//load xml
var xmlLoader:URLLoader = new URLLoader();
var xmlData:XML = new XML();
xmlLoader.addEventListener(Event.COMPLETE, LoadXML);

I am building a map app that allows you to drag a map around the screen and it is masked to only allow a portion of it to be seen as you zoom in. For zoom, I can only think of scaling the mc_1 (which is the map). Since my stage is larger than my map viewable area, i have placed a mc_2 as the background to the map. mc_2 is the "stage" for mc_1. So mc_1 is above mc_2.
I want to enlarge mc_1 by easing out...but don't know how to scale it where it looks like a real zoom effect. I figured I would just have the user click a + button and it would scale it to a predetermined size. how to ease it in/out?
Lets say my map was of the united states and I drag the map around my window and Texas is in the center point of the mc_2. How do I zoom in on Texas, instead of it just scaling mc_1?

What's the correct way to track mouse position, from Adobe Flash, when someone has: Started a drag within the Flash application (a MOUSE_DOWN event), Dragged the mouse outside the app or even the browser window (a MOUSE_MOVE event), and Released the mouse button (a MOUSE_UP event)? For example (imagine Stack Overflow is a Flash application):
Within the app, I'm able to track the mouse X and Y positions with a MOUSE_MOVE event listener, but I lose it when it goes outside of the browser... So, how do I track the position of the mouse no matter where it goes? For a good example, try Google Finance. Try dragging the chart around; it'll still drag around if you move your mouse out of the browser window, and the mouse will be outside of the browser when you release it.
Also, check out KOKO KAKA; If you click on the scrollbar (make the browser window really small) and move outside of the browser window, the scroll bar moves just like a real one would. I believe both only work because the MOUSE_DOWN event "captures" the mouse, allowing the Flash application to track the position of the mouse even when it is outside of the browser.

Code:
addEventListener(MouseEvent.MOUSE_WHEEL,mouseWheel);
function mouseWheel(event:MouseEvent) {
Map.scaleX = Map.scaleX + event.delta*.01;
Map.scaleY = Map.scaleX;
}
The problem with this code is that it scales from the registration point (0,0). Due to the other transformations I'm doing to this image at various times, it isn't possible to move the registration point. The image is larger than the stage and the user is able to drag it around. I want the mouse wheel to zoom in on the place the mouse is hovering over (or at a minimum...the center of the "view" they have...aka the stage)I tried doing this:
Code:
internalPoint = new Point(Map.mouseX, Map.mouseY);
externalPoint = new Point(stage.mouseX, stage.mouseY);
var matrix:Matrix = Map.transform.matrix;
[code]....
Which, incidentally, I'm using that whole portion of code to zoom into the state they will be in when they use the mouse wheel.

I have designed a menu that When you mouse over it, a custom cursor appears. When you mouse down it disappears and when you mouse up it returns. If you happen to mouse down and then drag the mouse off of the menu (whilst in mouse down) and then mouse up outside the menu, the custom cursor disappears. All good. The only issue is: If you happen to mouse down on the menu and then drag the mouse off of the menu AND off of the stage, i.e the SWF (whilst in mouse down) and then mouse up completely off of the stage, the custom cursor appears at the point it left the menu. I have tried to fix this using MOUSE_LEAVE but this dosnt work when the mouse button is pressed down. I have attached an FLA, SWF and the AS below.
Code:
stop();
import com.greensock.*;
import com.greensock.easing.*;
import flash.events.MouseEvent;

am hoping someone here might have some source in the little bag o' trix that will put me on the right road to achieving the following. i am trying to work out the best way of creating a movie that has buttons that when clicked will zoom into and centre a certain area of a larger movieclip?
and then a way of dragging the zoomed into movieclip around the stage area? or panning using x/y positions of the mouse. (and without asking for the moon on a stick - if the user clicks on a empty part of the zoomed mc - it zooms back out to it's original size position?)
any have any fla files or know of any good tut's or threads that can will give me a leg up to get it working? fingers crossed has done this before or know a good place to start?

I am trying to have flash draw a line from the center of the stage out and increment around the stage. Not sure what math I would use to do this though. So far I have the line going out to a certain point but not sure how to change that point so that it circles around whatever the dimensions of my stage would be.
So far I have this:
var linetox=0;
var linetoy=0;
var _stage=this;[code]...
which obviously moves the destination ending of the line lower and lower, just trying to get it to draw around the screen (like a clock)
