Flash :: Repositioning Objects Based On A Scale?
Jan 19, 2010
I have airplanes that are flying past the screen from a top down view. when the air planes crash, I scale them down to make it appear as if they are falling closer to the ground and farther away from the screen. I have turrets on these crafts as well. they are seperate objects from the air plan. I scale them down as well. The only problem is they dont reposition correctly. they stay in their x and y positions even though they are being scaled it looks as if they are being pulled away from the air plane. is it possible to reposition them correctly based on the size on the object they sit on (i.e. the air planes)

We are building an application in Flex where we have to scale and reposition the circles based on the changed screen resolutions. Example: Current resolution: (800, 600) I draw a circle at position (410,290) with radius 10 Now If i change the resolution of screen to (1440, 960) then the circle should be drawn at the same place on the screen with respect to the new resolution with relative increase in the radius.

Ive probably ran into some code like this before. just cant remember where. I have 2 display objects on my stage. One is rotating and the other is positioned 90 degrees from the rotating object. As the object rotates, the other object adjusts its x and y positioning from the rotating object..
If this doesnt make sense, then let me explain what I am trying to do. I have a spaceship in my flash game. this ship has 2 torrets siting on the left and right wing. as the ship turns, the torrets need to remain on the wings.

I would like to scale a movie clip based on how close the mouse gets to it, but flash slows when there are a ton of these. I'm looking for a new method
onMouseMove = function(){
var dx:Number = this._x - _parent._xmouse;
var dy:Number = this._y - _parent._ymouse;

Canvas.addChild() insists any DisplayObject added implements IUIComponent. But I don't want my core graphics engine dependent on Flex. Is there an obvious/common way around this, to have simple graphical objects like Sprites & Shapes in a Flex application? The individual DisplayObject children I want to add as children represent objects in a game world, like a spaceship or a missile or a horse...
Not sure if Canvas is the most appropriate container, perhaps Group or another class is optimal for a game-engine... example MXML & AS3 code showing a skeleton setup is most welcome. I'm targeting Flex4 & Flash 10, but Flex3/Flash9 solutions are still of interest.

I've been banging my head trying to figure out how to get this to work with no success... I have a class that extends MovieClip which loads a large image into it. This image has a mask applied to it to only display a specific section of the image. I need to be able to scale this MovieClip based on it's visible width & height while maintaining it's proportions.
I'm currently using Collin Moocks' approach (see it here:[URL]) to get the visible width and height of the movieclip, but I can't figure out how to get it to scale correctly based on those dimensions... Preferably I'd like to be able to set it's visible scaleX & scaleY properties similar to how you currently set the scaleX & scaleY, (i.e. movieclip.visibleScaleX = 1.5).

One of my main interests is playing games so I thought why not make a game? I see lots on the Internet games based in Flash so I thought that would be my best starting point to make actual graphic based games... (not to mention I actually got taught at university how to use flash to a certain extent). The game I decided upon was tetris. I'm sure you're all familiar with the block based puzzle game and might be able to shed some light upon what I am doing right and what I am doing wrong. So, I've firstly made my game screen with a window for all the blocks to come down in.
I've also put some dynamic text place holders ready for when I come to keeping track of how many 'lines' the player has scored, the time and so on in the right hand side of the screen. I have made graphics for the different colour 'building blocks' (just one block of 24x24 in different colours for each shape) and then used the 'building blocks' multiple times to create my shapes (I, J, L, O, S, T, Z). These blocks are called tetrominoes. Now I've come to a point where I need to import these tetrominoes randomly from the library and get them to appear in the middle just off the top of my block screen.
How do I import random objects from a particular folder in my library to the stage in Flash CS5 AS3? After realising a quick solution to my problem was not to be found quickly I then thought about what will happen to this block once it has been imported... Well, in Tetris the block moves slowly down until it hits another block or the bottom of the block screen. I know that I can do something with a detectHit() function. How do I get my block to move down the screen by a set amount of pixels every second or so?

I'm looking to create a rotating set of images, simulated to look 3D... that can rotate either left or right, reactive to someones mouse location.
The path of the images would look like a flat oval, and as the images came to the forefront, they would be at full scale, have the lowest position (high _y), have the highest depth (appear in front of everything else) and be dead center _x.
As they slide left or right, they would reduce everything by a relative 50% to the final shift (scale, _y, and depth) until they got to the end, moving in an upward arc following the oval path. When they got to the end, and kept rotating beyond (move in the opposite _x. but appear to follow the flow of the arc), continuing to decrease in scale, _y, and depth.

I have a CS4 document with many objects, motion paths over multiple layers. I want to scale everything, including the motion paths of each object. I've tried to do this by Clicking 'Edit Multiple Frames', then 'Selecting All Frames' and finally scaling everything via the Transform panel. Everything appears to have been scaled apart from the motion paths. Is there a way to do this?

This is unfortunately a quite complex issue to explain, so please don't get discouraged by the wall of text - it's there for a reason. i'm working on a transformation manager for flash, written with Actionscript 3. Users can place objects on the screen, for example a rectangle.
This rectangle can then be selected and transformed: move, scale or rotate. Because flash by default rotates around the top left point of the object, and I want it to rotate around the center, I created a wrapper setup for each display object (eg. a rectangle).
[Code]...
Now, to the question: should I use a different kind of setup, system or structure? Should I maybe use matrixes, if so, how would you keep a static width/height after rotation? Or how do I fix my current wrapper system for scaling after rotation?

Would anybody happen to know if there is a way to scale objects accordingly on stage when switching to fullscreen.. It's sort of like when the stage is set to "scale", and all the objects scale accordingly, but I'm trying to scale the objects while having the stage set to "noScale"..

Im currently building a little 3D particle engine in flash the uses sprites.to set the position of each sprite I am using the projectVector function below. (the viewTransform matrix is the particles world matrix concatenated with a perspective projection matrix)
var projectedPoint:Vector3D = Utils3D.projectVector(viewTransform, point);
sprite.x = projectedPoint.x;
sprite.y = projectedPoint.y;

im currently writing a piece of code where i need to get all children that are specific class or extend one.
currently im using this
ActionScript Code:
public function getConnections():Vector.<NodeConnection>{
var res:Vector.<NodeConnection> = new Vector.<NodeConnection>();
[Code].....
The problem with this is that 1st, string comparison is slow, and im expecting that there will be hundreds, of instances on stage. and secondly, It is very probable that i will extend the classes that i use in the functions, so their toString() will produce different name. e.g if i have on stage instances of "Node, ExtendedNode1, ExtendedNode2 " since they are all nodes, id like to all of them be returned.

How can you call objects based on properties they have instead of object names? For example if i want all the objects in an area to move somewhere else. Thats not what im trying to do but just an example. Also im using flash mx 2004

Im using Oracle, BlazeDS, Java and Flex. I have a list of objects displayed in a datagrid(Lets call them Main-objects. Each of these objects have a set of UserComment-objects associated with them(One-to-Many relation in the DB). These comments may come from two different "types" of users, distuingished with either a 1 or 0 in the UserComment-object's "userType" field. Each time the user selects a Main-object in the datagrid, the UserComment's related to this object is displayed in a separate datagrid below.Based on the introduction, i want to separate the UserComment's into two separate datagrids (one for each user-type), instead of the one i have now. So my question is: What is the best approach for performing this task? What is the best way of separating the UserComment's into two separate data grids based on the value of the "userType" field?

I've been trying to sort objects depths based on their Y position but have not been able to do it efficiently. I was able to successfully sort objects with a selection sort algorithm and a quick sort algorithm; however, both have only been partly successful. Selection sort gets about 8-10/30 FPS with 13 objects and gets about 14-18/30 FPS. This is not good enough as I figure I could have as many as a hundred objects to be sorted at once.
After digging around, I found that array.sort() is more efficient than a quick sort implemented in AS3 and that calling swapChildren() or swapChildrenAt() at every swap was bogging it down. So now I am copying the objects array and sorting it with sort() and then comparing the two and swapping displayObjects so as only to call the swapChildren() or swapChildrenAt() method once per element. It appears to be running, and at full speed, though it won't swap correctly. Here is my code:

What I want is to sort a Vector array of objects(not primitive), based on a propery(Number). (think character.zDepth). Generally the same thing as the sortOn function of Arrays, except that we don't have that for Vectors.
like myArray.sortOn(x, Array.NUMERIC)

So a small example of my situation...On my stage I have 5 items labeled item1_mc, item2_mc, item3_mc and so forth...they all have two keyframes on their respective timelines, one labeled "active" and the other "inactive". My code contains 2 arrays, inactiveArray and activeArray and a variable known as energy that regularly goes to and from 0 - 100.
What I am looking to achieve is basically the function of...
if energy >= "insert given items 'active threshold' 20, 40, 60, etc..." then add it to the activeArray, if it is not, remove it and add it to the inactive array.
all objects in activeArray gotoAndStop("active");
all objects in inactiveArray gotoAndStop("inactive");
I have tried many different ways of achieving this effect but I always end up with duplicates and extras or something doesn't move when it's supposed to, where it's supposed to, it just ends up into a giant cluttered mess and I start from scratch.

I have 2 MCs named box1 and box2. Each one has dynamic text field named content_txt (content_txt.autoSize = true) and loads some text data from XML file.Box2 is on the top and box1 on the bottom. I need function that checks the height of box2, or of its content_txt and puts box1 on exact distance along _y axis.I have tried with this code:
Code:
onEnterFrame = function () {
b1y = box2._y;
b1v = box2.content_txt.height; //or just box2.height
spacer = 20;
[code]....
but it slides box1 without exact calculating of box2 height.

The following code is a combination of samples taken from red5. Basically I am trying to combine a live stream subscriber with a chat box based on shared objects. I'm not a flash developer and have a very limited understanding of what is going on here.
// ** AUTO-UI IMPORT STATEMENTS **
import org.red5.utils.Connector;
import org.red5.samples.simplechat.BasicChat;
[code]....
I don't think that var chat is being initialized anywhere as trace(chat) prints 'undefined'. However var connector and var publish_video seem to collect their instances from the stage.
This sample code included those two and worked fine, but I can't make my additions behave the same way.
I have added an instance of BasicChat to the stage (I'm using Flash CS4) and have spent the past many hours playing with it's various properties, layers and groupings, but to no avail. why my var chat isn't collecting its instance from the stage?
