Manipulating frames in the timeline

[chiapa]

Hi everyone,

I've got a first frame in the timeline in which the stage has a play button that, when pressed, advances the timeline to the next frame, where the game should actually start, with UFO's and stuff flying through the stage. But I want the "action" to start only in the second frame of the timeline. I tried this, it doesn't work: the UFO's don't appear in the first frame but don't appear in the second either, as I wanted.

function Main():void
{
if (currentFrame == 2) //it's wrong, I was just trying...
{
Mouse.hide();
stage.addEventListener(MouseEvent.MOUSE_MOVE,mexe_ mira);
...
...
...
...
}
}

If I don't put the "if", in the first frame (with the play button) all the UFO's appear, flying across the stage. They aren't supposed to.
If I put the "if", there are no UFO's at all, in any frame.

Any ideas? Thanks
Chiapa

Can you post your fla file?

if you must put things in main timeline instead of putting them in separate MovieClips between which just change visibility status etc, something like this might work:

This starts checking what is the current frame and if it is 2 then it marks game started and calls the Main() function

import flash.events.Event;
import flash.events.MouseEvent;
import flash.ui.Mouse;

var startFrame:Boolean = false;

addEventListener(Event.ENTER_FRAME, onEnterframe);

function onEnterframe(event:Event):void
{
    if(!startFrame && currentFrame == 2)
    {
        startFrame = true;
        Main();
    }
}

function Main():void
{
    // now it is frame 2
    Mouse.hide();
    stage.addEventListener(MouseEvent.MOUSE_MOVE,mexe_mira);
    //...
    //...
    //...
    //...
}

Have you considered putting the code in a place that isn't the constructor? Like say, a different method?
