Анимация: метод play()

play()

// The cake has its own animation:
const nommingCake = document
  .getElementById("eat-me_sprite")
  .animate(
    [{ transform: "translateY(0)" }, { transform: "translateY(-80%)" }],
    {
      fill: "forwards",
      easing: "steps(4, end)",
      duration: aliceChange.effect.timing.duration / 2,
    },
  );

// Pause the cake's animation so it doesn't play immediately.
nommingCake.pause();

// This function will play when ever a user clicks or taps
const growAlice = () => {
  // Play Alice's animation.
  aliceChange.play();

  // Play the cake's animation.
  nommingCake.play();
};

// When a user holds their mouse down or taps, call growAlice to make all the animations play.
cake.addEventListener("mousedown", growAlice, false);
cake.addEventListener("touchstart", growAlice, false);
