Steps to create an animation.
1.When making a play finish the play sketch of the first sequence before adding a second sequence.
2.When adding the new sequence the players of the previous sequence will be copied to the new sequence with the
same tack to identify them when animated. These players can then be moved to their new position, click and hold
down left button and drag them to their new position.
3.If a sequence doesn't contain text or lines you might want to check the animation only box. The animated play
will then continue without a pause when passing this sequence.
4.When finished click on Animation in the special menu.
