In flash with as3.0, I have to call a function on the main stage from a movieClip

Question

I have to call a function that is defined on the main stage of my project, and I have to call it from a MovieClip, what can I do? I\'m using flash cs5.5 and AS3.0

Answer 1

if your MovieClip has a class, just add it to your main class using like:

var m:MovieClip = new MovieClip(); **addChild(m);

then you can get access into it's public function like typing:

m."functon name";

Answer 2

When I read your question it sounds as though you have a function defined in an action frame of your main timeline.

My answer may be out of reach for your current project, and ToddBFisher's answer is perfectly right. That said - I'm going to answer the question differently.

Instead of defining a function on the main timeline, set up a document class, define your functions there, and access the class's functions in your code. Keep as much code off your timelines as possible.

Answer 3

There are multiple ways to access the MainTimeline from objects on the stage. Probably the most reliable is 'root', but there is also 'parent' (but only if you MovieClip is a direct child of the main timeline).

// root should always work
Object(root).myFunc();

// parent will only work if your movieclip is a direct child of the main timeline
Object(parent).myFunc();

Note that you have to cast these are generic Objects (or MovieClip would work) because they return typed classes that don't have a 'myFunc' function in them.

You'll need this code on your main timeline:

function myFunc():void {
  trace("My function got called!");
}

Answer 4

Assuming your movie clip is a direct child of your main stage, in you movie clip you can do:

MovieClip(parent).theFunctionToCall();
