Hiding a button

Content

Hi

I wonder if anyone can help point me in the right direction.

I have a flash movie which imports variables from a plain text file, these define button names and urls.

I want to “hide” a button if no url is set in the text file.

on(rollover) {
if(button_url=“”) {

this._alpha=0;

}
}

I’m applying this to the as of the button but this doesn’t work.

Any help greatly appreciated!

The movie has to go out in Flash 6 (don’t ask!)

You could instantiate your buttons.

I’ve used AS2 here as its for Flash Player 6.

So if URL exists you instantiate the button, something like:


attachMovie("ButtonMovieClipName", "instanceName", 1);

The number is the layer.

You can also drop the button; something like this:


instanceName.unloadMovie();

Example:


if(button_url) 
{
   attachMovie("ButtonMovieClipName", "instanceName", 1);
}

If you have say 10 buttons just increment the instanceName and instantiate/deinstantiate them using code.

so my button needs to be in a movie clip to do this?

is there any way of dropping the alpha / or hiding the button itself?

thanks!

Your button would be in a movieclip yes; just create movie clip buttons.

You can drop the alpha; but thats not how I do it nor how I would recommend doing it. Also I think you’ll find that would just make it invisible, but the button still clickable.

As a rule of thumb you should always instantiate dynamic elements.

ok, thanks for the steer.
