Actionscript 3 variables and functions from child movieclip

[coma]

on my main time line i have 2 varaibles: "LastSelected" and "Flagged", which are used to control the navigation on the site im making. I also have a function called UnClick() which perfroms the rollout animation for the btn last selected and then jumps to the flaaged section. these are all on the main timeline.

now ive created a button symbol that is inside a movieclip called "HomeContent" and i need it to navigate the main timeline to another label "Services" and to do so i need to assign the 2 variables and call the UnClick() function from within the MovieClip.

this sounds like a simple thing to do but im kinda new to flash and AS3

can you provide us with some code. :)

okay well its a bit hard to show the actual code (cause its long and messy) so ive made this small and simple fla file (Attached) to better demonstrate my need.

on the main timeline, in the "AS Root" Layer:

var String1:String="Hello ";
var String2:String="World!";
 
function OutPut():void{
    trace (String1+String2);
}
 
OutPut();

in the Movieclip HomeContent in the "AS Home" Layer:

btnOutPut.addEventListener(MouseEvent.MOUSE_DOWN, LetSee);
function LetSee(evt:Event):void{
 String1="Welcome "; // A variable declared on the main timeline, AS Root layer frame1
 String2="Stranger"; // A variable declared on the main timeline, AS Root layer frame1
 OutPut(); // A function declared on the main timeline, AS Root layer frame1
}
/*---------------------Error Messages---------------------
1120: Access of undefined property String1.
1120: Access of undefined property String2.
1180: Call to a possibly undefined method OutPut.
--------------------------------------------------------------*/

Now I can't think of something else but you can just put your code on the main timeline :)
where is your stop just add

stop();

HomeContent.btnOutPut.addEventListener(MouseEvent.MOUSE_DOWN, LetSee);

function LetSee(event:MouseEvent):void{
String1="Welcome ";
String2="Stranger"; 
    OutPut(); 
    
}

hmm... i guess.
that would work but it really sucks that i cant do it from inside the movieclip (im sure a similar situation will come up sooner or later). so there is no way to call global varaibles or functions? that cant be right AS3 is meant to be a propper programing language that is meant to meet the standards the C+ and other languages are set to. it would really suck if AS3 cant.

im thinking that i may be able to set variables and call functions if i create a class that will set variables and handle functions for me. any ideas?

[spectator]

Yes If you create class that will be a solution, but what you say about the code inside something else, well there is a way, but I only can think of the _root which is not accessible in AS 3.0. You should create a class :)

Hi
I also had the same problem as you and i read your question and also sow the answers you got. I was not too happy with the answers so i sat and worked this one out myself.

The good news is that you can access the coding from the main time line from within the movieclip.
What I did was inside a mouse event function I wrote


“event.currentTarget.root.string = "this also works";


I had created the variable called string which is a String (var string:String) in the main time line. Then I called for this variable from within the movieclip timeline and use the event.currentTarget.root as a prefix for a mouse event responding function. And this worked. And also I using the same prefix and called for a function from the main time line and it worked too.
I hope this will solve you problem

Here i took some time and reworked on your file and it is working :) have fun

What a champ. I'm going to have a look at the code after work. Thanks for your help!
