ActionScript 3.0 :: Top-left Registration Point To Center Conversion (2D To 3D)?
Nov 16, 2010
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
[code]....

I start with a question: how could I change the registration point of a movie clip created or loaded at runtime? I want to move the registration point from top/left to center.

When you create shape on stage and right click and chose create object you can chose Registration point for the object you chose what corner will be used as center of coordinates for this object. Now onice you create object is there way to change this registration point e.g. i created it in center now i want to to be in upper left corner?

I coded an entire file based on the top left registration point of my movie clip. I want it rotate it to point at the cursor, but since the registration point isn't in the middle.. its not a perfect rotation around the center of the mc. Is there anyway to rotate it around the center of the movie clip without changing the registration point?
ActionScript Code:
stage.addEventListener(Event.ENTER_FRAME, aimBall, false, 0, true);
function aimBall(event:Event):void {
ball_mc.rotation = getAngle(ball_mc.x, ball_mc.y, mouseX, mouseY) -90;
trace(ball_mc.rotation);
} function getAngle(x1:Number, y1:Number, x2:Number, y2:Number):Number {
var radians:Number = Math.atan2(y1-y2, x1-x2);
return rad2deg(radians);
} function rad2deg(rad:Number):Number {
return rad * (180/Math.PI);
}

Can I set the registration point of a MovieClip (or other Display Object) to its center upon creation in AS3? the following
[Code]...
sets the registration point of myClip to its top left corner by default. Using Flash CS4 to set it to its center is just a couple of clicks, so I am wondering how I can perform the same action only with code.

I've got a scrolling image gallery which I have a zoom button that lets the user zoom in on the images... If they click on the stage, the scrolling stops. Now, if they try to zoom in, the image scales from the left side, since the images registration points are on the left side of the movie clip they're loaded into. This causes the images to shift right, but I want it to appear as if its a straight on zoom...

I'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 am moving movieclips around my stage in relation to the users mouse location. All of my movieclips have the registration point placed in the default top left corner. As an object moves off the stage to the left it suddenly disappears when the registration point reaches the edge of the stage. I would like to see the whole object move off the screen instead of just disappearing when the left corner reaches the edge. I would move the registration point to the right side but I would like the movieclip to be able to move off all sides of the stage (top, bottom, left, right)

So when you load a picture into a movie clip, it loads into the Top-Left hand corner.I really want it to load into the Top-Right hand corner. Is there a way?I am loading it via AS - not placing it manually, as I have a variety of images which are of different dimensions....

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.
public function Main()
{
var wereld:MainScreen = new MainScreen();
addChild( wereld );

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.

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 am using a slider component to scale a movie clip. Currently it scales from the bottom right corner (I guess this is default). I would like the MC to scale out from the center.
Current Code
// slider
slider.addEventListener(SliderEvent.CHANGE, scaleObject);
slider.minimum = 1;

I've been experimenting with senoculars transform tool for a while now. It's an awesome tool, I'm just having some issues getting it to do what I need it do. I think the problem is it does some really complex stuff but I really just needs some of the simpler features. I'm pretty close to just scrapping it and making a simpler one myself but I really don't want to do that.
My current issue is trying to get the registration point to always be the center of the object it's transforming. I was able to sort of do this by changing the line that creates the registration point to this: innerRegistration = new Point(_target.width>>1, _target.height>>1); but when the object is scaled the registration point gets messed up.
