How does it work?

If I create a character and a background, how can I merge them together?
The reason for it is so that all the finished animation and background is separate from any pans on the stage.

Whilst your question is vague, what you would do is hold them both in a container movieclip.

var container:MovieClip = new MovieClip();
container.addChild(finishedAnimation);
container.addChild(background);
addChild(container);

This would require you to have previously defined finishedAnimation / background. If you had not done, you would remove them from your stage and in your library tick "export for actionscript", give them a name and then:

var finishedAnimation:yourAnimName = new yourAnimName();
var background:yourBackgroundName = new yourBackgroundName();

Leaving you with:

var container:MovieClip = new MovieClip();
var finishedAnimation:yourAnimName = new yourAnimName();
var background:yourBackgroundName = new yourBackgroundName();

container.addChild(finishedAnimation);
container.addChild(background);

addChild(container);
