有没有办法在cocos creator中创建自定义事件和在类上分派事件？

const {cc} = require('cc');

let eventTarget = new cc.EventTarget();

const EventType = cc.Enum({
    CUSTOM_EVENT: 'custom_event'
});

eventTarget.on(EventType.CUSTOM_EVENT, (event) => {
    // 处理事件
});

let customEvent = new cc.Event(EventType.CUSTOM_EVENT, true);
eventTarget.dispatchEvent(customEvent);

cc.Class({
    extends: cc.Component,

    properties: {
        // 定义属性
    },

    // 定义方法

    // 定义事件分派方法
    dispatchCustomEvent() {
        let customEvent = new cc.Event(EventType.CUSTOM_EVENT, true);
        this.node.dispatchEvent(customEvent);
    }
});

this.dispatchCustomEvent();
