ActionScript 3.0 :: Zoom Mc_1 To Center Of Reference Point Mc_2?
Nov 10, 2009
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?

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'm trying to figure out how to find a point relative to the center of an object, modified by its rotation. For example, in the attached swf, I've been messing around trying to draw trails to a bitmap, coming out of the thrusters. I didn't have a problem at first, but as the ship rotated, the lines that were being drawn wouldn't remain relative.
http:[url]....
I'm sure this is because I have no idea what I'm doing, and I've just been sort of idioting my way through it. That aside, is there an easy way to find the point I'm looking for? For instance, say I want a point at Y -14 of my ship, but I want that to remain relative to the ship as it rotates.

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 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.

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?

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 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);

Looking for code to enable zooming in/out on a graphic or movie clip using mouse scrollwheel with origin of scale change being at the mouse cursor position. I have one where it is at top left. I also require it to stay proportional, when applied to a rectangular graphic my code makes it go letterbox on zoom out!

There is an Image control that when I click on it I need to zoom in (using the center/transform point where the mouse is clicked). I have the zoom transition working great, but when I set transformX & tranformY (with autoCenterTransform false) it doesn't zoom into that point.
Here is my code that only zooms in (not to a specific point)

basically just wondering if its possible to scale an MC about the center of the stage as opposed to the top left of the MC? I thought about setting the X & Y as stage width / 2 + MC width / 2 but cant as the user needs to be able to move the MC which is much bigger than the stage and zoom in on a point in the center rather than just the center of the MC.

I'm making a 3D room builder. The user places Sprites around the 2D stage and my script converts those Sprites to Papervision3D DisplayObject3D objects. I'm having problems with the 3D object positioning because Sprites have registration points at their top-left corner and 3D objects have registration points at their center. How can I make that conversion?ere's a scheme of how the 2 different coordinate systems work:
I've tried this code:
child3D.x = child2D.x;
child3D.z = child2D.y - child2D.y - child2D.y; // just to make it negative
