ActionScript 3.0 :: Object Disappears Once The Registration Point Is Off Left Side Of The Stage?
Sep 22, 2009
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)
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...
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?

Do you usually set the registration point in the upper-left corner ?I usually have always troubles with the registration point in the center.. or is maybe useful in any situation ?
I'm having some troubles trying to scroll a container MovieClip across the stage.I've attached an EventListener to the stage to track the MOUSE_MOVE MouseEvent, but it scrolls in a weird way (when halfway the screen it shows about 300 px of the container, when going below the horizontal centre, it goes up and disappears from sight.This is my code:
Code: private function moveHandler(e:MouseEvent):void {
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
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.
I need to have 2 kinds of masks, one with a registration point in the top left so that when I tween its height it expands downwards, and one with a registration point in the bottom left so that when I tween its height it expands upwards?how do i do that, with code ofcourse?i have made something but i dont know if its the right way:(this expands downwards, but i dont know how to get it to expand upwards)
Code: import gs.TweenLite; var subMask:Shape = new Shape();
I want to learn how you can change the registration point for the Canvas.I want to make a zoom of this component, but the point registration in the upper left corner! How do I move to the center?

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....
Is there a way to set the stage resize registration point to the top left rather than centre. I.e. when i set dimension (in publish settings) to 100% by 100%, when the browser is resized the stage width and height change to match it but the far left hand point is now in the negative figures and anything that was on the left hand side of the screen is moved towards the centre. Is there a way of setting where the stage resizes from so i don't have to update the position of the movieClips everytime stage is resized (which causes a slight juttering effect).
I am trying to scale a movieclip with AS3, but always using the center of the stage as the registration point. The movieclip is larger than the stage to begin with, and uses a slider component to slide back and forth. I'd like to be able to scale the movieclip using a button, but it currently uses it's own registration point (upper left corner) as the source.
Is there a way to force the scale to use the center of the stage?
I have an object which is converted into a symbol. I double click on this object/symbol and it goes into its own seperate timeline. For my coding purposes I would like to know how to change the registration point of the symbol so it moves along or is addjustable on a symbols its own timeline so a can create animations on an objects timeline without screwing up my codeing because objects don't register when their moved away from the registration point the compiler still thinks that the registration point is where it was previously.
I'm a relative noobie struggling to understand object registration points / center points. For example, in this image of an empty movie clip from an XML gallery I'm customizing for my site, there is a circle with a cross and an empty circle.
Can someone point me to a thread or article that explains object registration points, how they relate to each other and how (and why) to move them (or not)?
im trying to make my plane movieclip follow the mouse... which i have achieved although i want to give it a regestration point so that when the mouse turns or goes left, right, back etc, the front of the plane goes with it so it looks realistic aposed to a plane image moving left and right.
I'm a bit newbie to Flash, and I'm experiencing strange problem. I have a simple flash application, which when run in Flash player looks like this
the thing is, when i resize the Flash player window, a black frame becomes visible to the left and top of the stage. is it possible that these black areas start appearing on the right side, and the stage to be fixed on the left? The strange thing is that these black areas are not part of the stage, the (0,0) coordinate is there where white area starts and not in the corner of the window, and that's causing me problems.
I'm working on Flex component which can be resized using handles on the right and left (that is, if you click and drag the left side, the component will grow to the left, if you click and drag on the right, it will grow to the right).
Right now I am using:
var oldX:Number = this.x; this.x = event.stageX + (initial.x - initial.stageX); // Move the left edge to the left this.width += oldX - this.x; // Increase the width to compensate for the move to the left
But that makes the right side jump around, and generally looks ugly.
What is the "right" to do this? Is there something fundamental I've gotten wrong?
Edit: The jitter occurs on the right side of the component. When I set this.x, the component moves to the left, the screen redraws, then the width is updated, and the screen redraws again.
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 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); }
