【问题描述】：
我是 Phaser 3 和游戏开发的新手，所以我遇到了问题。我正在尝试重新启动游戏场景，但是当我运行它时出现“未捕获的类型错误：this.scene.restart 不是函数”的错误
var playbtn = this.add.dom(390, 600).createFromCache('play-btn');
playbtn.setPerspective(600);
playbtn.addListener('click');
playbtn.on('click', function (event) {
this.scene.restart();
});
这是我的全部代码

当角色击中炸弹时，会弹出“重玩”按钮，如果玩家点击该按钮，游戏将重新开始。这些是我的目标... 我正在从事的项目是一个教程示例，但任何建议或解决方案都会对我有很大帮助。谢谢
