恢复原样

class RestoreExample(Scene):
    def construct(self):
        s = Square()
        s.save_state()
        self.play(FadeIn(s))
        self.play(s.animate.set_color(PURPLE).set_opacity(0.5).shift(2*LEFT).scale(3))
        self.play(s.animate.shift(5*DOWN).rotate(PI/4))
        self.wait()
        self.play(Restore(s), run_time=2)

save_state方法用于记录当下状态。Restore动画将s恢复为之前记录的状态，等同于s.animate.restore()。
