Scenes, Flash

Start Flash using CS2

Draw something that changes in scene 1 using a shape or motion tween.

Go Insert, Scene

*Notice, you can switch between scenes here:

On scene 2, draw something that changes in scene 2 using a shape or motion tween.

Put in an additional layer, add actionscript to the layer in scene 2 that says:

GoToAndPlay("scene 2", 1);

When you play it, this should keep only scene 2 playing.

The benefit of scenes is it keeps things organized when your project gets big.  Also, it helps prevent bogging down in big projects.  Another benefit is if you are working on a big movie and want to test it, you can put actionscript in the first frame of scene 1 that says something like:

 GoToAndPlay("scene 5", 1);

This will keep you from having to watch the whole movie.
