ActionScript 2.0 :: Instance Name Not Eval'ing Correctly
Apr 28, 2003
I have a global map, when the user selects a continent it loads a seperat swf for that area. The continents grab variables from a database, and bring a bunch of variables into the movie.
One group is for the names of countries. It grabs the country name and it's 2 letter code. Then passes the country name to the local movieclip with that same instance name.
This works well for the most part. A couple countries don't load. Right now I'm looking at Asia. The country od Malaysia with it's code of "MY" produces errors half the time. Well most of the time.[code]...

I'm trying to work on my first flash game but I'm already having problems making my character move.I'm currently following this tutorial:However, when I try to test my game, I get an error saying:"Access of undefined property player_mc"In the scene, I have a square MovieClip called "player" and when you select it, in its properties I have given it the instance name "player_mc".However I still get the error. So I decided to change the object's name to "player_mc" as well but that still gives me the error. I don't understand why this isn't working.According to this, it's just to do with spell-checking... but yeah, I looked through my code and the objects and it's all "player_mc".

Basically I want to eval() a string like _level0.mc._x-=dist; where the "-" or "+" is a variable.You can paste this straight in and it should work.. only the last part (where it's doing the eval) doesn't.
Code:
this.createEmptyMovieClip("mc",this.getNextHighestDepth());
_level0.mc._x=200;
_level0.mc.createTextField("txt",_level0.mc.getNextHighestDepth(),0,0,200,200);[code]......

I have a response coming in from a server that contains a ton of strings that I need to eval to have them replace arrays already set as globals. So program fetches response, evals string into an array, and then we do stuff with the array. I've played around with little tests and can't get it working.
ActionScript Code:
var superArray= new Array('3','4');
var testArray="superArray=['1','2']";
function testEval() {
eval(testArray);
trace(superArray);

I was reading another query on this board about NOT using eval, as it had become deprecated, for attaching a name to a new MC. I have been using eval to check through all the objects, and to add ones with a certain name to an array.
for (i in this) {if ((typeof (eval(i))) == "movieclip" && substring(i, 1, 5)== "names") {
would there be another method of doing this using dot notation? sorry if this question seems a little muddled. I am new to flash, some things in it make a lot of sense and others are still confusing me.

I am passing flash a variable in string format and it looks like this
var stringVar = "new Array(new Array(1,3,4),new Array())";
Now i need to make an array out of it. I tried this:
var stringArray = eval(stringVar);
but had no success.

I'm trying to loop to dynamically create functions. I have 5 boutons and I don't want to duplicate 5 times the same code. This code works but I don't seem to be able to use the same eval trick on the variable "blnBtn05". Anyone knows why and how can I be make it work?

Does creating a new instance of an Object that uses an identical name to an older instance, delete the previous instance? Or should the original instance be deleted first? The code uses a ridiculous amount of XML vars. Isn't it less memory intensive to parse the XML and save the properties to an Object, and then delete the XML Object, rather than keep the XML Object around and reference it's child nodes directly? Is it better form to break up a huge XML file (>600lines/3200vars) into smaller chunks?

I have an air application, in which the user types javascript in a textarea, and it is eval'd in an mx:HTML component, but even with try/catch around the eval, and around the code in the eval, and an HTMLUncaughtScriptExceptionEvent handler, it still throws an error. htmlWindow is html.htmlLoader.window.

I have a clip containing 8 MCs, named id1, id2 etc, each of which contain a dynamic text field with the variable thisNo. I want to run a loop that inserts each digit from a randomly generated number into each of these MCsPatID is the random number, IDLength is it's character length.
for (i=1; i<(IDLength+1); i++) {
thisNo = PatID.substr(-i,1);

I'm trying to update an old flash 5 site I made years ago so that I can put video clips in it. I opened the file is flash cs3 and compiled just to see if it would work as is before modifying. It's hanging on a bunch of code, all which have eval() in them. It's been a loooong time since I coded actionscript so while I know that the bracket syntax is what I should be using, after trying various ways of writing it I just can't figure it out. Can someone tell me how the following should be written in Actionscript 2.0 and I can extrapolate from there?[code]...

I'm having problems with my usual eval methods of creating objects to read off dynamic values programmatically using concatenation. I've found the set command doesn't seem to work with objects that are dynamic....
Code:
function createobject(item){
//create it and store something in it
set ("_root.item"+item.stored, "data storage test for item "+item);
}function checkobjects(){
for (i=1;i<5;i++){
checkit=eval("_root.item"+i);
trace("_root.item"+i+".stored="+checkit);
[Code] .....
Running this produces the output of...
Code:
_root.item1.stored=undefined
_root.item2.stored=undefined
_root.item3.stored=undefined
_root.item4.stored=undefined
How to do this - basically I'm trying to load data, then use that to create dynamic objects and values within it, then I'm trying to work with those values by again using loops to read off the dynamic values during runtime. Obviously if these were "fixed" variables, then it would be easy, problem is that its impossible to use the new Object() command with dynamic names!
Previously I've used this:
Code:
checkit=eval("_root.item"+i+".stored);
trace("value is "+checkit);
Is it my imagination, or was this stuff a lot easier to do in AS1?

I'm trying to build an API in JS that will perform some operations and then execute the callback that's registered in AS when it's done. Because it's an API, I am just providing a JS method signature for another developer to call in Flash. Thus, the callback name that's registered in the AS part of the code should be a parameter that's passed in to the JS API in order for JS to communicate back to Flash.
For example:
[AS3 code]
ExternalInterface.addCallback("flashCallbackName", processRequest);
ExternalInterface.call("namespace.jsFnToCall", flashCallbackName);
function processRequest(data:String):void {
//do stuff
[Code] .....
Because the definition of the function is in AS, I can't use the window [function name] approach. The only way I can think of is to build the callback in a string and then use the eval() to execute it.

I have a variable call php_variable that loads from the php. It echos all the necessary variables. I have 2 array, Tel_start and Tel_area. The messages.text is just a text field I use to test if things are loading properly.

Having a hard time trying to resolve this issue, done a bit a of digging but can't find what i'm after. I'm pretty new to AS3 but know that Eval() has gone and been replaced with [] syntax. However, i'm trying to access a dynamic path to a clip and it seems that the array syntax will not allow more than one variable in a path.

I have a library object (SomethingMC) which extends a custom class (Something). Something, in turn, extends MovieClip.If adding SomethingMC to the stage within Flash CS3 IDE, is it possible for it's super class (Something) to assign an instance name from a class constant (Something.THE_CONSTANT)?
package
{
import flash.display.MovieClip;[code].....
The above does not work. It throws Error #2078: The name property of a Timeline-placed object cannot be modified. if the instance is assigned a name in the IDE, and it just doesn't work if no name is assigned in the IDE.

I have a BUNCH of bumpers of four types bounceUp, bounceDown, bounceLeft, bounceRight. during a collision which you hit determines the bounce so they always do the same thing so here's my question.....can i just name every bounceUp instance the same thing and then just add that one instance name to the list the collision detector checks?
i just dont wanna go through and name a hundred each of bounceUp s and bounceDown s individually as the potential for screaming increases proportionally.......

I am wrapping my brain around OOP in AS2. I am making two posts on two different subjects. My question here is: when should I use local instance variables, and when should I attach new properties to the instance object? (Feel free to correct my terminology.) Let's say I have a class for a scrolling background, which scrolls when I mouse over its edge. I want to put these values somewhere:
1) How wide is the border in which a mouseOver makes it scroll? This is basically a semi-constant I set it up once and keep it the same, unless the user changes it in an options menu to make the border wider or narrower. Call this scrollBorderWidth.
2) How fast is the background scrolling now? I want to track this so I can smoothly change the scroll speed over several frames. This is often changed. Call this scrollSpeed.
It seems I have two ways I can store and access these values and darned if I know which is better practice. METHOD A: Make them local variables in the class, so the scrolling background instance has them as local vars. I set them up thusly:
