 5  1. Basic parameter animation: circle.animate.x(100)
 6  2. Sequence animation: breath.animate.expansion.sequence(0, 1, 0)
 7  3. Chained animations: circle.animate.x(100).y(50)
 8  4. UserData parameter animation via name lookup
 9  
10  The fluent API should make animations more readable:

12      self.play(Move(circle, x=100), run_time=1)
13  
14      # New fluent style
