常用组件模板

单例管理器

import { _decorator, Component } from 'cc';
const { ccclass, property } = _decorator;

@ccclass('GameManager')
export class GameManager extends Component {
    private static _instance: GameManager = null;
    
    public static get instance(): GameManager {
        return this._instance;
    }
    
    onLoad() {
        if (GameManager._instance) {
            this.node.destroy();
            return;
        }
        GameManager._instance = this;
        // 不销毁节点
        // cc.game.addPersistRootNode(this.node);
    }
}

事件管理器

import { EventTarget } from 'cc';

export class EventManager {
    private static _eventTarget = new EventTarget();
    
    static on(event: string, callback: Function, target?: any) {
        this._eventTarget.on(event, callback, target);
    }
    
    static off(event: string, callback: Function, target?: any) {
        this._eventTarget.off(event, callback, target);
    }
    
    static emit(event: string, ...args: any[]) {
        this._eventTarget.emit(event, ...args);
    }
}

对象池

import { NodePool, Prefab, instantiate } from 'cc';

export class PoolManager {
    private static pools: Map<string, NodePool> = new Map();
    
    static getPool(name: string, prefab: Prefab): NodePool {
        if (!this.pools.has(name)) {
            this.pools.set(name, new NodePool(name));
        }
        return this.pools.get(name);
    }
    
    static spawn(name: string, prefab: Prefab) {
        const pool = this.getPool(name, prefab);
        if (pool.size() > 0) {
            return pool.get();
        }
        return instantiate(prefab);
    }
    
    static recycle(name: string, node: any) {
        const pool = this.pools.get(name);
        if (pool) {
            pool.put(node);
        }
    }
}
