ActionScript 3.0 :: Reference Parts Of An Array And Keep Both Instances Updated?
Dec 20, 2011
long title i know. This concerns the data handling for a physics engine i'm writing. At the moment, i divide objects in my engine, into three broad groups (2d arrays), which allows me to save on a lot of processing. every object has an array for its records which is held inside one of the three main arrays. however, this division is causing more processing work in other spots, particularly where finding things is concerned.
what i'm wondering is if it would be possible to make a master list, but still keep my three smaller arrays, and for an object's records to be synchronised regardless of whihc place i update it. actually going and synchronising it would be extra work that kind of defeats the point, but what i hope to do is reference object records from the master array, so thst both the master array and the three small arrays hold references to the same data objects

I have an XML document with different companies and links to different text sources such as "about" etc for each firm.
Now in my company presentation class I want to send an ID reference so if a user clicks on Microsoft the links point to Microsofts information etc. Im loading all other information through another XML and everything works fine, its just the links I cant seem to figure out.
This is my XML

I have two MC's on stage,
MCmenu is a button array,
MCtext is a collection of text with frame labels. It's labeled as MCtext
The menu buttons tell MCtext to play the frame label as the button clicked. This *used to work*, but Flash was laggy as hell so I updated it. Now the same code returns #1009: Cannot access a property or method of a null object reference. at MCmenu/itemClicked()
Code:
function itemClicked(butn:Event):void {
parent.MCtext.gotoAndPlay(SomeArray[butn.currentTarget.label);
}
I've tried just using a frame number, but still the same #1009
I've tried the Script Assist to target the MC on the stage:
using root.MCtext... still the same #1009
using this.MCtext... returns a #1010

I am trying to get the length of an array through mxml (not actionscript). I have the following:
<s:Application

Why does test2 show the correct array length but test1 is stale?

[code]My code will:
- loop through the Grid array and place each tile on the stage
- assign RedBall a random Grid coordinate and places it on the stage at that coordinate
I want to be able to click RedBall, which will create a border around the tile beneath RedBall, and create borders around the tiles above, below, to the left and to the right. BUT, I don't want to reference the tiles by their distance in pixels from RedBall or from each other; I want to reference the tiles by their coordinates in the Grid array. So I want to:
- get the coordinates of RedBall
- use those same coodinates to reference the tile at the same coordinates in the Grid array
- use the tile's coordinates to reference the tiles above/below/left/right
- apply a border to all these tiles
What's the best way to reference an instance of a tile? Should I apply a name to each instance as it's created in the loop? like myTile.name = "tile"+i+"_"+j; ? If so, how do you reference that instance later? Just tile1_3 ? Do you have to prepend it with root, or stage, or the class it was originally created in? Do you have to use getChildByName? OR, can you still reference it later without having given it a name?

Here is a simple example of what I need to be able to do:I have a movieclip, "main_movie", in the main frame, which has multiple instances inside of it...for example "mc_1", "mc_2", and "mc_3".I am unable to figure out how to dynamically reference them. Please look at the code below and let me know what I'm doing wrong.
for (var i = 1; i <= 3; i++) {
main_movie.mc_[i]._visible = false;

It's me again and I'm running into a problem. So, I have this movie clip that is nested inside multiple movie clips. I want to tell Flash to perform an action when that movie clip hits another movie clip in the main timeline. It's just collision detection for a game using the hitTestObject code. I was thinking of using MovieClip(root), but that won't work since it's nested so much.

There's 3 boxes I'm indexing through with a timer. They disappear in sequence. How do I make them reappear?

var timer:Timer = new Timer(555);
timer.addEventListener(TimerEvent.TIMER, onTimer);

I'm not to particular about the sequence they disappear and appear, but it need to keep going in a loop.

I'm working on a project where I have Multiple instances with the same actions.
Instead of typing out
btn1._visible = false;
btn2._visible = false;
btn3._visible = false;
btn4._visible = false;
Could I store these instances in an array so that I could minimize my code to something like:
btnArray._visible = false;
I've tried to do this but it seems to read the instances as strings instead.

I'm setting up some Radio Buttons. The desired effect is when you click a button, it calls a function which loops through an array of the button states, switching them off.
The stumbling block is changing the state of the buttons from on to off. I'm sure it's an issue with the way I'm trying to get the instant name (eg radioBtn1) into the MovieClip Variable 'currentRadioName'.
The error I receive is: TypeError: Error #1034: Type Coercion failed: cannot convert "radioBtn1" to flash.display.MovieClip.
So I'm trying to stick some object into a MovieClip object, which obviously doesn't work.

I have a movieclip tweened of a lightbulb bright then fading. 50 or so instances are placed within another movieclip and given instance names of bulb0 to bulb50. I have a stop action on the first frame of this movieclip.
Other animation within the main movieclip is activated on rollover and I have used actionscript to place this main movieclip on the stage and to control the other animation within it.
Within my external as. I have an array as follows:
var bulbclips:Array = new Array();
for (var i:uint; i < 58; i++) {
bulbclips.push("winNav.bulb"+i);

the user needs to select an answer from a dropdown list. I am then creating an array that will store the answer to each question when the user clicks the submit button. Each of the drop down menus is named sequentially. So what I am trying to do is write a while loop that will increment through and read each of the values into the array so I can process the responses later. The issue that I am having is writing the syntax to recognize the Instance name of the specific drop down I am trying to reference.
Here is the basic code I am using:
var Store:Array = new Array(2);
public var Increment:Number;
Increment = 1;
[code]....
So the DropDowns instance names are DropDown1, DropDown2 etc... It works fine if I manually enter in each instance name (but there are 43 total and I don't want to do each one individually).
I am assuming that I need to setup some sort of variable to temporarily add the increment number to the "DropDown" and then use that as the reference:
Increment = 1;
while (Increment <=2){
ItemNumber = "DropDown" + Increment;
Store[Increment] = MovieClip(Scroller2.Form_Scroller.content).ItemNumber.value;
trace(Store);
Increment++;
}
But when I do that, I get the following error message:
TypeError: Error #1010: A term is undefined and has no properties.
at combotest/submitted()
I assume this is because it is looking for an instance of ItemNumber instead of the instance of the value of ItemNumber.

My project downloads an array from a MySQL server that has URLs for pictures in it. Part of my script then downloads these pictures and splices the array (removing the URL and replacing it with the bitmap). Now i need to use those bitmaps on the stage but i need two instances of the same bitmap at the same time, and it seems like flash is having a problem with this.
How do i create two instances of the same array bitmap?

I'm trying to add an instance of a MovieClip inside an array. Inside the House Class is a property called HouseObjects. Inside that array, I created a Comp and a Light class. MovieClips are dynamically placed on the stage, via linkage. The MovieClips also act as "toggle buttons." If the button state is ON, value is 1. If the button state if OFF, value is 0.
If the value is 1, I am trying to add MovieClip instance inside the onList Array. Inside that array will be all the instances that have a button state ON.
I created a property called objSelect.
var objSelect:Object;
That variable holds the currentTarget selected. I'm trying to pass it to function trackItems to either push/pop it in the onList array, based on the button status.
I receive an error for this line:
onList.pop(objSelect);
Incorrect number of arguments. Expected no more than 0.

I've continued with it and have hit another hurdle. When I run the loop to load in the XML images, inside the same loop I add instances of a "thumb" movieclip onto the stage. It's just a little graphic that I want to use as thumbnail buttons. So for example, if the XML loads in 3 images, 3 instances of the "thumb" mc also load onto the stage. I currently give then unique names in the loop but that name gets overwritten each time the loop runs. How can I record each name of the instance? I'm guessing an array but how do you populate an array with a loop?
Then, I'm hoping if those names are recorded in an array, then I can reference the different thumb instances (so they can do different things with the images) and also use removeChild on them when I close the gallery and load in the next gallery. Here is my code so far,

When I change the variable "i" inside the statement to 3 or other values,

where each of my buttons have a dynamic text label.
So this button is a symbol, and the instances are named let say btn1, btn2, btn3. The label tag name inside the symbol is btnName.
How I can make this work if I define my array on top level? How I can make sure that the label btnName will have the correct array name for each btn instances?
found out the benefits of .children usage...
btn1.children.btnName = xArray[0];
btn2.children.btnName = xArray[1];

I have a source array with simple Point instances in them (just an object with x and y properties). I want to have a resulting array with the cumulative result of calling Point.add() to each of the instances. (e.g. the resulting point object is a result of adding the current point to the total of the points before it in the source array.) is this possible to dynamically do this?
