Javascript 只运行一次精灵工作表，createjs

我想知道是否有人可以帮助我制作我正在用createjs库制作的精灵表动画。所以我有一个狐狸的角色，我想在用户打开页面时立即加载它。我得到了运行好，它重放一遍又一遍，但我只希望它运行一次。是否有方法停止动画，或者有一个事件侦听器在动画到达最后一帧时停止动画？任何帮助都将不胜感激。谢谢大家!

  function projectFox() {

    createjs.Ticker.addEventListener("tick", stage);
    createjs.Ticker.setFPS(8);
    foxanimation();

你可以这样做

太好了，成功了！非常感谢。所以我也想要它，这样当只运行一次后，它就会从舞台上移除……我是否需要写一个if语句s
