Using Flash Pro CS5 and I have a question more out of curiosity really. I have a simple gallery that I made by simply making buttons to move forward or backward along a timeline inside of a movieclip. I applied the "Fade In a Movieclip" code from the snippets to each image so that it'll fade when you go to it. The previous image however does not fade away when clicking away from it and because of the speed of the fade that I have set it's still quite effective.
I'm curious though is it possible to set a button to fade out the previous movieclip while retaining the simplicity of the "Go to Next Frame" code? I know how to set a button to fade out a movieclip but in order for it to work with this method I imagine I would need something to the effect of "Fade all movieclips" so that it could remain generic and be effective across the timeline. Is such a thing possible?
I'm not clear on what you are doing and what code you are using, but if your gallery lies within a movieclip where you just move from one frame to the next, then if you were to fade that container movieclip you would be effectively fading all movieclips within it.
