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'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 have a MC in an AS3 animation and I want to increase its height from bottom to top which would mean that the registration point should be bottom of the MC and center of width (horizontal center).

The Registration Point is set to the top upper left corner and I would like it to be in the center of my loadMovie.The Zoom transition only zoom from left corner and need to be center equal sides. How do I do this. My image size is "width 400px height 240px
View 4 RepliesI'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

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.
View 2 RepliesWhen 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?

View 1 RepliesI have read a few discussions on changing the registration point on a movieclip but don't seem to work. I have a movieclip with embedded mcs. I can se that the nly way of changing the reg point is by saving as a mc again ie: creating another one and upon creation choose the reg point.

View 5 RepliesI'm making a custom collision class, and I need to know the registration point of the targets so I can use the bitmap.hitTest(); function, and not all of my movieclips have their registration point in the upper left side, so I'll have to do a little calculation according to the registration point of each movieClip, but I don't seem to know how to obtain the registration point with as3.
View 3 RepliesIs there a way to extend only the bottom part of a dynamic Movieclip? I tried to change the height or to scale my mc but it always makes the change relativity to the center of the Movieclip. I guess I should define a registration point and change the height according to it but i'm not sure of how to do it
View 2 RepliesNormally, this is a simple task if the registration point is either top left or dead center of the movieclip. Unfortunately, this may not (and likely will not) be the case for the movieclips I am trying to position, so I was wondering if there was a way to center a movieclip in a given area without knowing it's registration point.registration point via the Matrix class or any other method, as it's very important for positioning of the movieclips inside of it.
View 6 RepliesTo load an image onto a movieclip, the mc's registration point must be top left. Is there a way of loading the image on the whole movieclip, when it's reg point is not top left. In other words to set where to start putting the image in reference to the movieclip
View 2 RepliesI 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.

var wereld:MainScreen = new MainScreen();

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 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);
}
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.
There is not setRegistration point method. So, how to set registration poing in AS3. Do any body know about it ??

View 3 RepliesI have a movie clip on my stage with various elements in it. When I edit this movie clip all the coordinates for the various elements have really random values because the registration point is not set to the top left corner of the symbol but I can't find any way to change the registration point - nothing I've found online so far works.
