ActionScript 3.0 :: Finding A Point Relative To A Center Point?
Nov 9, 2010I'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.

ActionScript 3.0 :: Top-left Registration Point To Center Conversion (2D To 3D)?
Nov 16, 2010I'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

View 1 RepliesActionscript 3 :: Flash - Center An Object Around A Point After Scale?
Oct 27, 2011I'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)

ActionScript 3.0 :: Find Center Point Of Mc With Dynamic Scale?
Dec 1, 2010I'm trying to add some zooming functionality. The problem is that when you zoom in and out, it scales the MC up and down from where the registration point is. This means That when I'm far from the position of the registration point instead of zooming the in straight it also makes it appear as if you are travelling towards the registration point.
To offset this effect I want to calculate the amount of pixels I need to offset the Map by so that it appears as if you are zooming in directly.
So just as a test I've put a little ball inside the map(called "center") which I'm trying to keep in the center of the map.[code]...

View 1 RepliesActionScript 3.0 :: Zoom Mc_1 To Center Of Reference Point Mc_2?
Nov 10, 2009I am building a map app that allows you to drag a map around the screen and it is masked to only allow a portion of it to be seen as you zoom in. For zoom, I can only think of scaling the mc_1 (which is the map). Since my stage is larger than my map viewable area, i have placed a mc_2 as the background to the map. mc_2 is the "stage" for mc_1. So mc_1 is above mc_2.
I want to enlarge mc_1 by easing out...but don't know how to scale it where it looks like a real zoom effect. I figured I would just have the user click a + button and it would scale it to a predetermined size. how to ease it in/out?
Lets say my map was of the united states and I drag the map around my window and Texas is in the center point of the mc_2. How do I zoom in on Texas, instead of it just scaling mc_1?
