I'm creating a webpage where all the content is within the same swf. In order to get things to work I have all my different content in different MC's. Each of those separate MC's have two frames inside. One where it's empty and the other where the content is displayed. To make this work I have a variable name 'page'. My menu is supposed to pass a string to this variable and at the same time trigger a transition to be played ('doors' sliding over and hiding the stage).
Then the transition sets all my content MC's to the hide position. Then it checks what the page variable is and sets the corresponding content MC to show before the 'doors' open again. At least that's how it's supposed to work in theory. But I haven't figured out how to do all this. First off I don't know how to get my menu to pass that string to the 'page' variable. Here's my menu with the problem area marked:

I want to pass a string variable to a SWF so that I can specify a XML file to load without republishing the SWF. When I assign the string variable to a textfield it is correct.But when I use that variable in the loader it does not display the XML from that file.You can see below that I commented out the string "lesson_11/images/0301_objectives.xml".If I put this string in the loader it works, if I use the string variable in its place it does not work.
Code:
var xmlFileToLoad:String;
var myQueryString:Object;

How to display the correct digits. For instance, if the answer is 97%, I want the display to show 97, not 11. Please feel free to view the SWF or look at the FLA file to see[code]...
View 5 Replieshow you would target a function's local variable through a concatenated variable string.For example:
var txt = "Hello World";
function testing(msg) {
var test1 = msg;[code].........
I'd expect the trace to be "Hello World" but rather is given "undefined". So if variables created outside functions are created on the main timeline, where are local function variables created and how would you access them?
why wont this work?
some_mc["nested_mc_name"].onPress = function():Void {
trace ("test")
};
I'm trying to make a dynamic function so I can pass a string var for the name of any nested movieClip I want on the fly.
how I can pass a variable calculated in a function, to the stage.
View 9 RepliesI was just wondering if it's possible to pass a variable from one swf to a function on another swf?
I have 2 containers on my main stage, each one loads an external swf, I want one to send a variable to a function in the other container.
I simply tried calling the function by doing _root.container2.fncTest("works"); just to see if it works
and in container2 I have
Code:
function fncTest(test):Void {
myText = test; //dynamic text box on the stage
}
but that didn't seem to work.. Do I have to make the function public or that only works for classes?
I have an external log file which name changes each session, with the format XXXXX.log
I need to load it inside a swf to show its data, but each time the logs name is different, I need to open the .fla, changing the name of the file and then republishing the swf.
So I have made a simple script to load another .txt, to type manually in it the 5 number of the logs name and load it externally inside the swf:
Code:
var logNumLoader:URLLoader = new URLLoader();
logNumLoader.dataFormat=URLLoaderDataFormat.VARIABLES;
logNumLoader.addEventListener(Event.COMPLETE, loadedLogNum);
[Code]....
While I cannot assign the value of logNum to the last function, the .log cannot be opened.
Is is possible to pass easing function as variable in AS3?g.
TweenLite.to(mcDelimiter, resizeTween, { x:(stageWidthHalf-(initStageWidthHalf-mcDelimiteri_X)), ease:Elastic.easeOut } );

View 2 Repliesthe idea is that the site keeps tracks of whatever page is current and passes this variable to the alpha function which will target that movie instance to fade when moving to another page - then that page's name will be assigned to current.this is the code that i have now..
#include "alpha.as"
evolution.onRelease = function() {
this[current].gotoAndPlay(2);

I'm trying to pass a variable to another frame but it's not working, can anyone please explain how to do this.
(I'm trying to build a video player--I have buttons for various videos on one frame and the player on another frame.)
So i have 4 buttons, that represent values: 10, 50, 100, 1000
When i click one of them i what a global variable declared: pulic var stake:int = 0; to e initialized with the value of the button pressed.
So i have the following code:
stake0050_btn.addEventListener(MouseEvent.CLICK, changeStake);
i would like to have a function changeStake, witch will update a variable called stake.
How can i tell the event listened to call changeStake with an argument?
How do i pass a variable to a function from an event listener which is inside a function Below is a function that is called when after loading some variables
function dataOK(mydataevent:Event):void{
var j:int = 0;
do {
trace(j);
[Code]....
This is a simplified version of the original code. The above function generates an error because j is undefined in the function. I am wanting to get the variable j when the button is pressed.
How do I pass the variable j to the Button_Click function?
I am running a loop to pull thumbs into a containing movieclip from an xml list. What I want to do is have the thumb's parent movieclip fade in after they are done loading, but I can't figure out how to reference the parent once it's loaded.My code(which currently doesn't work the way I want it):
var vsThumb:articleBox;
var currentarticleX:Number = 0;
var articleLinkURL:String;

How can I combine the following functions and still pass a different string to the buildUI(); function?
I have two functions that do the same thing only at the end they both call a function and pass a String value to the function. This string value is the only thing different.
Below is are my eventlisteners and functions as they are now:
female_start.addEventListener(MouseEvent.MOUSE_DOWN, startFemale);
male_start.addEventListener(MouseEvent.MOUSE_DOWN, startMale);
//FUNCTIONS THAT DO THE SAME THING AND BOTH CALL buildUI BUT PASS A DIFFERENT STRING.

How do I pass a variable to function when calling it with interval.
This:
Code:
doFlip(1);
to something like this:
Code:
myInterval = setInterval(doFlip(1),2000);
Code:
onEnterFrame = traceMe("test")
traceMe = function(param){
trace(param)}
If that won't work then would someone explain how you get something to execute a predefined function and pass a variable...
I COMPLETELY MESSED UP MY CODE AND DID NOT CHANGE THE MOVIECLIP NAMES WHEN COPING IT INTO STACKOVERFLOW. SO IT MADE NO SENSE.

top_icon.addEventListener(MouseEvent.MOUSE_DOWN, topApp);

I'm trying to make children of a tile and put them in their respective locations. To do that, I need to know what kind of tile is to be created, but if I just use my old method:[code]I will have to use a chunk of code like this for every single imaginable tile. Obviously, that is not efficient! So I'm trying to optimize it by having what tile type is to be posted saved in a string, then using the string to refer to what child is to be created, something like below:[code]how to make the above code work. Surely, there is a way to do this?

I have new a object in the main stage var

in main stage:
1. how can i access the variable "sequence" in "mc_rect"
2. how can i pass parametre from main stage to mc_rect via function setSequence(data:int)?
3. how can i call the function in addSequence() in mc_rect.
in asp.net, i usually use mc_rect.sequenct,mc_rect.setSequence(data), mc_rect.addSequence() to achieve my goals......btw, can function in mc_rect return out result to main stage?
