I have a sprite and a tween created using actionscript.
the sprite resizes correctly but the center of resizing is the upper left corner.
How can I set the resizing point to the center using actionscript ?
I'm trying to Resize a panel using a Resize Effect using its center as the anchor point. I've been googling for some information and the only thing I have found is to set the horizontalCenter and verticalCenter to 0, but this is not working for me. The panel keeps resizing from top/left corner.
View 1 RepliesI'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.

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 dynamic image loading into a movie clip and i dynamically created a transform box around it. However the anchor point of that transform box is coming on the left top instead of in the center, which is not letting the image transform properly. how to dynamically put the anchor point to center through AS2?

How Can i Set registration point to to the loader at the center by using as3 ?
View 5 Repliesbasically 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

Using the new 3D features in CS4. I know you can change the 3d center point manually via the Transform panel, but does anyone know how to do this dynamically at runtime? (ie via code)
View 1 RepliesI've created an mc which functions as my map and controls to go with that which allow the map to be moved around and key points navigated to and zoomed in on at varying zoom levels.I'm using scaleX and scaleY to scale the map mc and a list of x and y positions to correctly position the map for each key point.When I want to go to a certain area I perform this calculation (offsetX and offsetY are the center of the screen):
newX = posX * scale + offsetX;
newY = posY * scale + offsetY;
Then I tween the position and scale of the map to smoothly scale and move the map to the correct position:
var tween = new TweenLite(_background, EASING_SPEED, {x:newX, y:newY,scaleX:scale.getScale(),scaleY:scale,ease:EASING_TYPE,onComplete:moveToComplete,onCompleteParams:[room]});
I now need to implement a zoom in / out function and this is what I'm struggling with. The zoom should use the center of the screen as the reg point for the scale, so I've been trying something along the lines of the following to get the correct positioning:
var newX = offsetX - (offsetX - _background.x) * scale;
var newY = offsetY - (offsetY - _background.y) * scale;
So in my mind this gets the distance from the current position of the map relative to the center point of the screen (offsetX, offsetY) then scales that distance by the new scale. However, this is clearly wrong because it's not working and the positioning of the map is wrong.I've also tried using a transform matrix to get the correct values but I know even less about them and not got the right results.
function scale(target:MovieClip, center:Point, scale:Number):Point {
var m:Matrix = new Matrix();
m.translate(-center.x, -center.y);//move the center into (0,0)

How to find out different circle's center point of a bitmap?
just like photo above, how can i locate the 2 center points of circles?
i only know using .getColorBoundsRect to get a point, but this only apply to one circle, in fact i wanna get different points according to the bitmap.
I'm trying to add some zooming functionality. The problem is that when you zoom in and out, it scales the MC up and down from where the registration point is. This means That when I'm far from the position of the registration point instead of zooming the in straight it also makes it appear as if you are travelling towards the registration point.
To offset this effect I want to calculate the amount of pixels I need to offset the Map by so that it appears as if you are zooming in directly.
So just as a test I've put a little ball inside the map(called "center") which I'm trying to keep in the center of the map.[code]...
Is there a way to use the scaleX and scaleY property in conjunction with the Tween class to scale from the center?ActionScript Code:[code]above unfortunately only scales from top left. This is not a class I can go in and move all the content by hand (so that the registration point is in middle) as it's all dynamic. I've looked al over but none seem to make use of the Tween class.

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 trying to make a text effect where on every frame the textfield increases in size and decreases in opacity. I'm using the scaleX and scaleY properties of my dynamic textfield to enlarge, but it's doing so keeping the left registration point fixed. I want to make it scale up radially outward, or with the center point fixed.
View 4 RepliesI'm trying to see if there's a way to change the registration point of a MovieClip that's importing an image dynamically?Here is my code where I add an image to an "overlayHolder":
overlayBitmap = _loader.getBitmap( _data.id + "-overlay_image" );
overlayHolder.addChild(overlayBitmap);
overlayHolder.x = _data.overlay_left;
overlayHolder.y = _data.overlay_top;
What I need to do is rotate this image later on, upon interaction from someone, but need it to rotate with a center-registration.I've seen a bunch of tutorials/forums talk about centering a registration point when you're drawing a Sprite on the stage, but not when you're importing an image.
I need to make a MovieClip rotate around it's center point to the left or right depending on mouse drag. I got some basic semblance of what i want going, but it's pretty hackish. Normally i calculate the angle and such but i only really need to use the distance the mouse travels and apply it to the movieclip and for flavor add some nice easing when you let go.

1. Is there a way to scale up an object from its center even if its registeration point is at the top left? can that be done using TweenMax?2. can I apply the same tween on two objects at the same time? basically what I want to do is load up an image to the stage, and then tween its scale from 0 to the original size along with another movie clip behind it that would form some sort of a border for the image. and I want to scale them up from the center.
