But i have a rectangle and i want to scale it using actionscript with a tween (part of a series of functions that i am writting for one of my buttons) so i am able to adjust with a tween its width but it uses the left part of the rectangle. I want to scale the width of the rectangle from the center point of the rectangle and not the upper left corner. How can i actionscript that?

I want to create an animation which simulates a camera pulling backward through a forest of trees. I've created a tree symbol and I can scale it down over time, which looks pretty good. So theoretically I can generate a whole punch of these trees on either side of my stage and gradually scale them down toward a common vanishing point in the middle of the stage (and I will also gradually move the vanishing point off to the side to simulate the camera pull back transitioning into a sideways pan). The problem is that scaleX, scaleY attributes always scale down toward a preset registration point on the symbol that I don't seem to be able to change programatically at runtime, whereas I need to be able to scale the tree toward the vanishing point.
The only solution I've come up with is to parent the tree symbol to another invisible symbol whose registration point IS at the vanishing point, then scale down that invisible symbol so that the tree scales down and also transposes itself in the direction of the vanishing point. But this feels cumbersome. I bet there is a way to do this with matrix math, if only I had a better understanding of it.
I am testing with scaling a cube, like so
Code:
private function growCube():void {
TweenLite.to(cube3, 2, {scaleX:1.5 , scaleY:1.5, scaleZ:1.5} );

I have a scale up and down function that increases or decreases the size of an external loaded image inside a loader. What i am now trying to do and having trouble with is playing certain messages when the scaling reaches a certain point.
For instance when the user uses the 'increaseScale' function and scales 'image_Content' up by 40% its original size then 'warning_msg.visible = true;'
When they increase it by 65% then 'stop_msg.visible = true;'
This will then respond the same way if the user decreases the scale back to 40% and so on.
I cannot work this one out, i have posted the code below and have attached the fla file...

I am working on an application that will allow a user to scale an image. The issue that I am having with the method below is that the scaling is always taking place on the previous scale point. For example: If I scale the image up one and then scale the image down one. I have to scale down twice to get it back to the point I want it to be.
Here is my current code:
private var sourceBMD:BitmapData = testImage.source as BitmapData
private var matrixScaleX:Number = 1;
private var matrixScaleY:Number = 1;
private var baseScaleX:Number = .05;
private var baseScaleY:Number = .05;

I'm trying to scale a container/parent movie clip up so that I effectively zoom in to a point referenced by one of its children. I've figured out how to use globalToLocal to get that point at the center of the stage, but the problem is the registration point for the container clip is (and needs to stay) at the upper left, so when I scale the container clip up, the point does not stay in the center of the screen. Here's my code:

Vector Scaling Object Without Affecting the Original Point
View 1 RepliesAll though I can scale down the size of my objects and can shift them to their correct positions when scaling. I cannot shift them to the correct relative positions, relative to the screen centre.
Code:
level=1; //starting scale level
public function scaleOut(level:int) // scale to a level 1-4{
for (var r = 0; r < Main.ballArray.length; ++r){

I've search through all the threads with "scaling" and "resizing" and can't find the solution.
Basically I have a GUI element on a gallery that I don't want to scale, while the rest of the page is free to resize/scale.
I think I need to add a listener of some sort to the stage, but I'm not sure how to do this.
I'm building some navigation that extends all the way from left to right across my SWF. When the window resizes, I'd like the nav buttons to get wider but not have the text on the buttons get wider.
The buttons themselves are rectangles with a vertical gradient and a stroke around the outside. I'm using 9-slice scaling so the stroke doesn't scale, but the middle (gradient) gets wider or narrower.What'd be great is to be able to select an object or layer and say "don't scale, even if the rest of this movie clip scales". Is there a way to do that, or will I have to do it via actionscript?
i have a diagonal movieclip that I am trying to scale along with the background video. The background video scales perfect, I am attaching the diagonal movieclip (br in the code as bottomright) with addChild
Instead of scaling with the window, it seems to repeat such as the image is displaying. this is the main section of the code that is doing the scaling
var br:mc_bottomright = new mc_bottomright();
addChild(br);
//proportional scale
if ((stage.stageWidth / stage.stageHeight)> (owidth/oheight))

I am trying to achieve an effect of scaling a movie clip on click...very similar to [URL] When the user clicks on See, Hear, Play and Shop boxes, the boxes expand. I have created a box movieclip that has a bar on top. This bar is a movie clip inside the box movieclip. When i try to scale the main box movieclip, the internal bar movie clip scales as well. How to stop this?
View 2 Repliesreally sorry to bring this one up again. I've managed to create quite good working gallery. What I'm trying to now is create a menu that is attached to the scaling part but does not scale it self - in other words just changes position. here's an example of what I mean: galleru #1

What am i doing wrong?
It's been a long time since I've done any work with actionscript, and alas I've forgotten nearly everything. I've tried to look for a tutorial that would explain basic animation with actionscript, but the one that I found on Kirupa was no longer there.
Basically I'd like to do this:On the stage I have a movieclip and I'd like the movieclip to move along the x-axis to a certain point and then back to the starting point again. The moving speed of the movieclip should also be adjustable.
I'm creating a game in flash for a university project, and learning actionscript and programming as I go. I'm very much still at a beginner level - at the moment al I have is some actionscript for drawing rectangles and moving them about the screen. This is what I'm having trouble with at the moment: I have a class called 'Creature', and I want instances of it to interact with each other. I want them to do something when they come within a certain distance of another instance. And I want them to be able to pick a random other instance to get the location of, in order to do something with that information.
What I think I need is: A function for telling the distance between two (x,y) points.
A way of referencing the nearest other instance of the class. And a way of randomly selecting from all of the instances of the class.
How to convert 3d point to 2d point? I've found next formula in Internet(camera is situated in origin)
[Code]....
But these formulae give me strange result when z are less than zero(z<0) I need build line from A(100,100,100) to B (100,100;-100) As you can see these equations give really strange result when I try to convert B point in 2D dimension
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 am using AS2 with Flash 8 Professional So, my problem is that I currently have a man in the middle of the screen, who shoots a line towards the mouse when I click. However, when I use hitTest to see if the line collides with another object, Flash recognizes the line as a large box if it is diagonal, so the hitTest isn't very accurate. The line only satys there for one frame, so I can't have the usual moving-bullet-style. I am either looking for a way to create an imaginary line with AS from the starting point to the mouse and beyond, and tell whether or not this line intersects with an object... or some other way that I haven't thought of to fix my problem. Keep in mind that the line rotates from a center point towards anywhere around it for 360 degrees.

View 1 RepliesI am trying to develop a Quadratic Bezier Curve using the graphics.curveTo() method. Initially when i drag mouse to draw the shape, i use start point and end point of mouse to draw the curve line. I assume control point at any position below or up to the line. An draw the curve using this control point. some what like:-
[Code]...
Now i add a tip on this curve segment. I have x and y position of tip. I want to change the curve segment by dragging tip. but now i don't have the exact control point according to tip position. If i use tip coordinate as control point it reduce the height of curve and now tip does not lie on the curve segment. What i have to do is calculate the exact control point on the basis of tip coordinate. But i failed to get this point.
how to use these in order to make an object move from point A to point B in an arc.Think of that classic game where you have to input the angle and power and try to hit your opponent.
View 1 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.
From the Robert Penner code given in this tutorial: [URL] i was wondering why controlx and controly has to be so complicated. I've tried changing it to just _root._xmouse but it messes up. I don't get this, shouldn't the curve point be the same point as the mouse?
