Actionscript 3 :: Flash Zooming In (scaling Up) To A Specific Point Within A Clip
May 24, 2011
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:

Basically I want to know if there is a way to go from a zoomed in version of something, and then seeing the whole image in another frame. (By pressing a button)
Let's say there's a tree, I would bascially like (upon pressing a button which I can do) to zoom out and see the whole scenery. Is there a way I can do this without actually changing the size of the image?

I am working on an application that uses raster images, so it only looks good at native resolution.
Is there a way to force the graphics to never be scaled?

I have a client who wants some things in Papervision that I'm not sure how to do, namely: when the user clicks somewhere on a model, zoom the camera into that point.
I would use a tween engine to tween the camera forward, but as moveForward is a method, I'm not sure how I'd enter this data into a tweening call.
ActionScript Code:
Tweenlite.to(camera, 1, {??????});
Second, I need to set the camera to lookAt wherever the user clicked on the model. How can I tell what the closest vertex is next to the mouse click?

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 am very much new to AS3 and Flash and had a problem trying to get my Flash timeline to pause at a specific point if the mouse was over any part of the stage. If the mouse was not or no longer over the stage I wanted the timeline to continue playing where it had left off.
I managed to solve the problem after a few hours and would like to share my first piece of AS3 - it might help someone else who has a similar problem, or you might be able to improve it.
One of may main objectives was to make sure the code cleaned up after itself and left no listeners or timers running.

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;

All 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){
// scale radius
Main.ballArray[r].bRadius *= (oldLevel / level);

I've scanned through the forums, but can't seem to find an answer to my question. I'm trying to move (tween) a movie clip 800 pixels along the x axis (horizontally) when a every time button is clicked. I don't want to move the movie clip to the 800 "x" pixel mark. Yet, I can't seem to move the clip an additional 800 pixels whenever the button is pressed again - it keeps starting from the original spot. I am new to ActionScript...
My code is below:
btnBottom1.addEventListener
(MouseEvent.MOUSE_DOWN, playHandler);
function playHandler(evt:MouseEvent):void {
import fl.transitions.Tween
import fl.transitions.easing.*;
var twTeen:Tween = new Tween(mcbottomFlap1, 'x', Elastic.easeOut, mcbottomFlap1.x, +800, 3, true);
}

How do I listen/respond to a specific cue point by name in AS3?
I have this listener which runs a function as soon as a cue point is reached, but I can't figure out how to run different functions for different cue points.

Whenever i want to declare a point with a specific value, it takes me three lines:[code]It isn't a huge amount of effort, but i'm becoming tired of doing this hundreds of times. Is there an easier way?I've tried doing something like this:[code]but that gives me an error, because it only accepts one input parameter.how can i do this simple operation in one line ?This is also important to me because i'm making a fair bit of use of static classes, (non instanced, making use of static public vars) where (afaik) i cannot run code. I want to be able to declare global point variables in a static class, without having to use some external class to set the values.

I look at professional animations and notice the camera-like effects they manage to put into these animations. I'm wondering how I can do the same without having to just enlarge or reduce a movieclip across the stage. Is there any way to add a camera view on your animations or do you just have to bear with Flash's basic necessities?

What I'm trying to do is make a dial-type of interface, where you click on a point on the edge of a circle and that point will rotate to another point at the top of the circle. What I can't figure out is how the make "Point B" rotate to "Point A", where "Point A" is always fixed at the top of the circle and "Point B" (and Point C and Point D, etc...) are located along different points on the edge of the circle. I'm using the tween function to rotate, so what I need to figure out is how to get the difference in the rotation between the two points.

I'm new using Flash.I have a video player and now we are implementing an HD button, the player always starts the video and 360P format and stream begins, if the user click on the HD I need to save the time of the video when it was clicked and then call another file. mp4 720P and start it at the same point that was recorded.I've tried various ways using CONNECTION.STREAM.seek(TIME); and always starts at (0), I feel that because of not being in Buffering he does not understand

I have a file that loads in several flvs.At certain points during the flvs, I need to trigger events on other timelines.Right now, I have them set up as listeners using enterFrame to detect playheadTime.This works, but is too hard on the CPU that is running the file.Is there something similar to VideoEvent.COMPLETE that could trigger events at other specific points in the flv?

I have a slider which I want to use to rotate an image around it's center. This normally is easy but my problem is the clip is made dynamically and the size changes so I can't use the default registration point and I need to assign the center point before I rotate it. I found the rotateAroundExternalPoint function which rotates around a center point fine. How to get it to rotate to a certain angle and then have it stop at that angle. The rotateAroundExternalPoint increments the rotation rather then allowing me to set the angle to rotate to. Is there anyway that I can set what angle to rotate my clip to? It right now increments the rotation by the x coordinate of my slider bar (slider_position.x).
Code:
import flash.geom.Matrix;
import fl.motion.*;
var mat:Matrix = clip.transform.matrix;
addEventListener(Event.ENTER_FRAME,EnterFrame3);
function EnterFrame3(event:Event) {
var center_point_x = clip.height / 2
var center_point_y = clip.width / 2 //
MatrixTransformer.rotateAroundExternalPoint(mat,center_point_x,center_point_y,slider_position.x);
clip.transform.matrix = mat;
}

I'd like to start playing a web-based video at a specific time, say 2 minutes in, even if the video hasn't been downloaded that far. I thought I could just "seek" to that time but that apparently only works when the video is buffered first.
So for example, this:
Code:
nc = new NetConnection();
nc.connect(null);
ns = new NetStream(nc);
ns.play("[URL]");
ns.seek(123);
video.attachVideo(ns);
Seems to work if you have the video cached or buffered or whatever, but if you don't it gives the "NetStream.Seek.InvalidTime" error, which makes sense. I want to know if it's possible to start playing a video at a specific time, even if the video hasn't loaded up to that point.

I have multiple movie clips on my piece. Each clip is of an an image, and when the mouse curser goes over the image, the movie clip begins (making it bigger).If you run your mouse curser all over the screen, they all activate at once.I want the clip to only activate after the mouse is on the specific clip for more than a few seconds. I know I need a timer. How do I do this? What is the code and where does it go in mine (below)?

I am trying to animate this piece with frames.
Basically, I have adrop down menu, which contains about 20 buttons. Each button is set to _root.Keys_MC.gotoAndPlay("frame label"); a specific from within the Keys_MC which is on the main timeline.
The problem is, no matter which one I click, it always links me to the first frame of that movie clip.
