如何在Cocos Creator场景之间发送最终比分？

// EventManager.js
const { EventTarget } = require('cc');

class EventManager extends EventTarget {
    static instance = null;

    constructor() {
        super();
        if (EventManager.instance) {
            return EventManager.instance;
        }
        EventManager.instance = this;
    }

    static getInstance() {
        if (!EventManager.instance) {
            new EventManager();
        }
        return EventManager.instance;
    }

    publish(eventName, data) {
        this.emit(eventName, data);
    }

    subscribe(eventName, callback) {
        this.on(eventName, callback);
    }

    unsubscribe(eventName, callback) {
        this.off(eventName, callback);
    }
}

module.exports = EventManager;

// GameScene.js
const EventManager = require('./EventManager');

cc.Class({
    extends: cc.Component,

    properties: {
        scoreLabel: cc.Label,
    },

    onLoad() {
        // 订阅事件
        EventManager.getInstance().subscribe('gameOver', this.onGameOver.bind(this));
    },

    onGameOver(score) {
        this.scoreLabel.string = `Final Score: ${score}`;
    },

    endGame() {
        const finalScore = 100; // 假设最终比分为100
        // 发布事件
        EventManager.getInstance().publish('gameOver', finalScore);
        // 切换到结束场景
        cc.director.loadScene('EndScene');
    },
});

// EndScene.js
const EventManager = require('./EventManager');

cc.Class({
    extends: cc.Component,

    properties: {
        finalScoreLabel: cc.Label,
    },

    onLoad() {
        // 订阅事件
        EventManager.getInstance().subscribe('gameOver', this.onGameOver.bind(this));
    },

    onGameOver(score) {
        this.finalScoreLabel.string = `Final Score: ${score}`;
    },

    onDestroy() {
        // 取消订阅事件
        EventManager.getInstance().unsubscribe('gameOver', this.onGameOver.bind(this));
    },
});
