why code snippet #1 works, but code snippet #2 doesn't? i thought the array operator would work in this case...
CODE SNIPPET #1:
Code:
for (i=0;i<products.length;i++)
{
// XML data code
for (j=0;j<prodItems.length;j++)

Why nested loops must be used. I have this code that I took from the Training from the source book:
v = 0;
i = -1;
while(++i < 2){
j = -1;
while(++j < 2){
[Code] .....
What I don't understand is why I have to have this to create two columns couldn't I just change the while (++i < 2){ to
while(++i < 4){ instead.
I have the following function but despite using the break statement, it doesn't seem to be stopping after it finds a match in the array:

I'm trying to build a musicians site. I'm populating menus, the musicians page, and some other stuff with XML. getting all the attributes (of the artists CD) for each artist. Here's one artist entry in my XML file:
Code:
<ARTISTS>
<ARTIST>
<NAME>AP.9 FED-X</NAME>
[Code]....
Yeah, I don't know how to handle several CDs for each artist. I can see I need a nested loop, but do I store those CD attributes in an array, or create a variable like some_mc["CDLIST"+j] ???
Then I gotta think about building the discography movieclip. I'll worry about that later. What I got working so far is at [URL]
The code is supposed to receive one system id and then scan around that system in all directions, with each direction having its own length. It is like scanning a rectangle around that system where 9*9 = 81 systems.The code works very well; but the problem. I get 8 duplicate results and there is a complete row missing from the results. The one just above the middle row. I think the problem is in the topsystem integer but I don't know what is wrong with it.[code]if you watch the part of the code that has if statements. this part handle the edges.specially zero and 10k. about what i want to do. think about it like a 9*9 dots field in rectangular shape. has 9 rows and 9 columns. each dot has an id from 1 to 10k. the input is the id of the dot in the center of the field (column 5, row 5). as now i know this centeral dot id. i want to loop through the whole field to find the other dots ids using topsystem(the distance between the centeral dot to the upper edge).downsystem (the distance between central dot to the lower edge). leftsystem (the distance between central dot and left edge).rightsystem (the distance between central dot and right edge).the code is working fine but there is 8 missing ids that replaced by 8 duplicated ids.
View 1 RepliesI have a program where I have around 100 LatLng (latitude longitude) points, and i have to get the largest distance between any 5 of them but you can only go forward (so if latlng_1 is the point number 5 latlng_2 can only be point number 6,7,8,....,100).
<-- skip the colored thing if its unclear
So I calculate the distance like this:
Code:
Select allfor(i=0;i<points_num;i++) {
for(j=i;j<........
// three more for loops
// and than calculate the distance between all five points and compare if it is larger than previous...
The problem is that the program stops responding for about 2 minutes to calculate this and I would like to know if there is anything I can do to calculate this thing faster? Yes I can reduce the point but than the thing I want to get is less accurate and even if I reduce the points I still want the calculation to be as fast as it can be.
when I use hittest and eval?
View 1 RepliesBasically 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.

var superArray= new Array('3','4');
var testArray="superArray=['1','2']";
function testEval() {
eval(testArray);
trace(superArray);

View 3 RepliesI 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 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 having problems in setting three variables using a for loop and then passing these variables to my function. I think it's something to do with the set function I'm using, because my colorFadeTo function claims it's being passed an undefined variable.

var current = circles[i];

base.mitem2y = mitem2._y

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.

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]...
View 1 RepliesI'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.

It display the correct string. But when I use Tel_start[0] like above, I got undefined. So here, the actual quesetion, what's the proper way of storing those variables and displaying it?
Is there any way to execute arbitrary code in Flash, like javascript's eval()? I'd like to take some code as a string and execute it, if possible
View 2 RepliesI have 15 sounds in my fla; I imported them to the library and exported all sounds with the name s1, s2, s3, ... s15 I created a function that recieve the number and then play the sound. In AS2 I could use eval like eval("s" + n), but in AS3 I can't!
[Code]....
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 am making dynamic post values to post to a URL.

Maybe I am doing this the hard way with eval, is there an easier way, such as passing an array of post variables?
