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 2 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 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).
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 2 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.
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'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)

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.

i have the follow issue :
I have a point which is setted at the border on a component, with changed transform point to the center of a component in order to match the component rotation.
the important part is when i try to get the point XY after rotation - they remains the same as before rotation.
how to get XY, after rotation ( changeing point.rotation property to specific degrees of rotaion )
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?

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.
