ActionScript 3.0 :: Find Most Left And Top Right Point In A Sprite?
Aug 8, 2009
I once needed to pan a sprite full of movieClips (picture 1) which were draggable with no bounds so you could drag them up and left (higher than sprites registration point).
You could also drag them down and right and expand a sprite that way (as well) but that didnt matter.What did matter was how much is 'up' and 'left' from the sprite registration point so i can include that in my formula for panning.
This was easy to find, i just sorted my array of movieClips, sorted on x and sorted on y after each drag, and thats how i got my up and left points.
Now I am trying to do that same thing, exept my movieclips inside a sprite have a custom rotation (picture 2), so i also have an up and left point, except this time up and left are caused by rotations of movieClips inside a sprite... (and these are dragable as well with no bounds)

I know some basic trig. but how do i find an angle from an anchor point and a moving point?
adjecent = _root.anchor._x-_root._xmouse;
opposite = _root.anchor._y-_root._ymouse;
hypotenuse = ((adjacent ^ 2)+(opposite ^ 2)) ^ 0.5;

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 seem to be having difficulty figuring out the code required for mouse over and scroll left to right. Basically, I have arrows either side of the window and I would my timeline to smoothly go to the left or the right when the cursor is over the arrow.

Way with actionscript to determine the right and left side of a movie clip? I have a row of dynamiclly loaded pictures that load into a movieclip and then have arrows that scroll the photos left and right using an interval and _x +=10. The scroll works great. Only problem is, it just goes on and on and on if you keep pressing the arrow. Is there any way to tell it where the left and right side are and not to let either side go past a certain point.

I've checked this behaviour: If I define a sprite (by programming) as:
var square:Sprite = new Sprite();
square.graphics.beginFill(16750899, 1);
square.graphics.drawRect(0, 0, width, height);
square.graphics.endFill();
return square;
When I check the position of the sprite ( square.x, square.y), they reference the TOP-LEFT CORNER.
If I create a symbol by Flash CS4 and export to Actionscript (I also associate one class which extends Sprite for doing "new()" in my code):
var square: MyClassExtendsSprite = new MyClassExtendsSprite();
When I check the position of the sprite (x, y), they reference the CENTRE of the sprite!

How can I know if a point is contained inside of an Sprite in Flex?
For example:
// My example point
var A:Point = new Point(5,5);
// My example sprite
var s:Sprite = new Sprite();
s.graphics.lineStyle(1,0x000000,1);
s.graphics.moveTo(0,0);
s.graphics.lineTo(100,100);
The point A belong to sprite s because its position is inside of it. Is there any function to know it? I want to do it for all kind of sprites, so use math formulas to calculate linear or quadratic equations (line, circle, rectangle, etc) is not valid for me.

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:

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 read the Movement using ActionScript tutorial [URL]. My question is: How can I make the box stop at a certain point, instead of disappearing. What I want to do is to have a picture move from right to left, and then have it stop when it reaches the left side of a banner that I'm trying to make. I'm working with an image of a ship, and I want to make it look like it's floating from the right, and when it reaches the end, I want it to stop there and have text appear on the right side of the pic.

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 searched online and found this script that is supposed to rotate and image but I'm not sure how to use, where to put in the degree angle that I want my sprites to rotate by. Also, I get an error. 1084: Syntax error: expecting identifier before leftparen. 1084: Syntax error: expecting rightparen before leftbrace.
var point:Point=new Point(spr_box.x+spr_box.width/2, spr_box.y+spr_box.height/2);

I'm attempting to write a racing game. I've loaded in my image, I brought it to the stage and now, all I want to do is rotate it from its' center and not upper left corner.
The code:
racer.rotation += 5;
rotates from the upper left corner. How do I rotate from the center of the car/sprite? I've tried putting it into a container but I'm unsure on the coordinates of the container because I tried to set the x,y coordinates to half the sprite image but y'know, it's not doing what I expect it to.
ActionScript Code:
if (arrowLeft) {
var container:Sprite = new Sprite();
[Code]....
I will never sneer at another racing game! I didn't think it would be this hard to do a simple rotate of 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.
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 have a column of objects down the center of the stage and I need them to randomly point either to the left or the right. They have been placed using a for loop so I can't point each one individually. I was told I could use Math.random to flip their scaleX position but I can't get it to work.

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();

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 am generating sprites programatically like this:
this.food = new Sprite();
this.food.graphics.beginFill(0xFFFFFF);
this.food.graphics.drawRect(0, 0, 10, 10);
this.food.filters = [new GlowFilter(0xFF6699, .80, 5, 5, 2, 2, false, false)];
this.food.graphics.endFill();
[Code]...
I basically want the food sprite to spin slowly about its center, not its x and y value which is the top left corner of the sprite. How can I make the anchor the center of the sprite?

I am making application which will dynamically create sprites via action script and copy the sprite's image to a bitmapdata object via .draw() function. I would like to store the location of the sprite's transformation point and insertion origin (which would be set within the flash editor when the sprite is created/imported.) Is there a way to access the location of the transformation point and the insertion origin via ActionScript? I just want to read it, I do not need to change it.

I've looked over many forums and pages to sadly learn that you can not reset/change the registration point of a movieclip dynamically. Though I am curious if or how I could go about assigning the registration point to a sprite instance I create at runtime. To give you a more concrete example of what I'm doing:
I create an instance contentWindow in my code to be animated (a 300px by 200px rect with registration in the top left corner)I create a Sprite instance imageHolder in my code and add it as a child to contentWindow I then add various images to imageHolder through a Loader object referencing an XML file. imageHolder's top left corner is oriented to contentWindow's registration point. (Leaving me with an oddly oriented imageHolder if the contentWindow's registration is centered, and will only re-size from that origin) Since imageHolder will be switching out various sized images it would be much more aesthetic to have the sprite's registration point centered. So since as3 defaults it to top left shouldn't there be a way to alter it at instantiation of the sprite? Then I could set my contentWindow's registration to center and the empty sprite would center all content loaded into it?

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)
