Button inside movie clip to call function in main timeline

[Mylo Farmer]

Hello again.

I'm having a bit of a hard time with calling a function in the main timeline through a button in a movieclip. Is there anyway I can make this happen?

The mc is in the main timeline and in it I added a button with this.removeMovieClip(); and so far it works, but when I try to call a function from the main timeline it just doesn't seem to work.

Thank you in advance

hi,

and in it I added a button with this.removeMovieClip();

Are you sure?

The code, attached to the main timeline, should be something like:

my_mc.my_btn.onRelease = function()
{
 trace("button clicked");
 myFunction();
}

[Mylo Farmer]

thank you for the reply, but it still doesn't work. it won't even trace the button. I even tried adding _root. to it but I keep getting nothing.

Notice that both the MovieClip and the Button must exist in the same frame the code is defined.
i.e., if you have

trace(my_mc);
trace(my_mc.my_btn);

you have to get the correct paths

Here's an example.

[Mylo Farmer]

Nope, I still get nothing. Did it exactly as you put in your fla, but no luck. it won't trace the button at all, no matter what I do.

Would it make any difference that my button is on frame 15 of the mc?

[nunomira]

hi,

Sure it would.

Notice that both the MovieClip and the Button must exist in the same frame the code is defined.

You can't assign code to something that doesn't exist.

You may use something like:

my_mc.onEnterFrame = function()
{
    if (this.my_btn != undefined)
    {
        this.my_btn.onRelease = function()
        {
            trace("button clicked");
            myFunction();
        };
        delete this.onEnterFrame;
    }
};

This will make sure my_btn exists.
Obviously the code and my_mc have to exist at the same time.

Another alternative is using the first piece of code, and make both my_mc and my_btn exist, but hide my_btn by placing it out of the stage. (one keyframe out of stage, another keyframe in the desired position).

Thank you for the reply, Nuno. As a matter of fact, I didn't quite understand this part. What exactly would be putting a keyframe out of the stage? Do you mean in the library?

[nunomira]

Take a look at example2 to understand what I meant.
example1 uses the onEnterFrame

[Mylo Farmer]

Thank you for the examples, but neither work for me. Would you have a look at my fla to see if there's nothing blocking this code? (note, I removed any code to this button).

It is on layer "desistir", mc name is "telasair" and bt is "botaosair".

[nunomira]

You're attaching the MovieClip via attachMovie().
You'll have to add the code after the MovieClip is attached.

The layer you mention (desistir) also has that MovieClip, but that's not the one which is used as it doesn't even exist on frame 5.

Thank you for having a look at it. So you mean that if I add the code straight after the attachMovie() and move layer desistir to frame 5 I might have a chance at it?

Would the code look something like this?

_root.leaveBtn.onRelease = function ()
{
	para_sons();
	_root.attachMovie("sairjogo", "saindo", 755);
	_root.saindo._x = 0;
    _root.saindo._y = 0;
	quitgame = function ()
{
    i = 0;
    for (;;) 
    {
        if (i >= nitens) 
        {
            return;
        }
        bloco["mc" + (i + 1)].campo.type = "dynamic";
        bloco["mc" + (i + 1)].campo.tabEnabled = false;
        if (bloco["mc" + (i + 1)]._currentframe != 2) 
        {
            bloco["mc" + (i + 1)].resp = bloco["mc" + (i + 1)].valid[0];
            bloco["mc" + (i + 1)].gotoAndStop(4);
        }
        ++i;
    }
}
;
telasair.onEnterFrame = function()
{
    if (this.botaosair != undefined)
    {
        this.botaosair.onRelease = function()
        {
            trace("button clicked");
            quitgame();
        };
        delete this.onEnterFrame;
    }
};
	}

Nevermind the code above, I just realised I did something completely stupid lol. The actual code goes something like this:

_root.leaveBtn.onRelease = function()
{
	para_sons();
	_root.attachMovie("sairjogo","saindo",755);
	_root.saindo._x = 0;
	_root.saindo._y = 0;
	wtfsound = new Sound(this);
	wtfsound.attachSound("wtf");
	wtfsound.start(0,1);
	_root.saindo.onEnterFrame = function()
	{
		if (this.botaosair != undefined)
		{
			this.botaosair.onRelease = function()
			{
				trace("button clicked");
				quitgame();
				this.removeMovieClip;
			};
			delete this.onEnterFrame;
		}
	};
};
quitgame = function ()
{
	i = 0;
	for (; ; )
	{
		if (i >= nitens)
		{
			return;
		}
		bloco["mc" + (i + 1)].campo.type = "dynamic";
		bloco["mc" + (i + 1)].campo.tabEnabled = false;
		if (bloco["mc" + (i + 1)]._currentframe != 2)
		{
			bloco["mc" + (i + 1)].resp = bloco["mc" + (i + 1)].valid[0];
			bloco["mc" + (i + 1)].gotoAndStop(4);
		}
		++i;
	}
};

Thank you so much for your time and help, Nuno. I really appreciate it. It's finally working! Muito obrigado, de coração!
