为 Minecraft Script API 中的部分接口创建了 wrapper，并提供简单的事件管理器和任务管理器，另附有一些便于代码编写的一些小工具。

import { EventPriority } from "../EventPriority.js";
import { manager } from "../EventManager.js";
import { EventListenerData, sEventListenerData } from "../decorators/EventListener.js";
function listenEvent(listenOptions, callback) {
    let tevent;
    let priority = EventPriority.NORMAL;
    let ignoreCancelled = false;
    let eventOptions = undefined;
    if (listenOptions instanceof Function) {
        tevent = listenOptions;
    }
    else {
        tevent = listenOptions.event;
        if (listenOptions.priority)
            priority = listenOptions.priority;
        if (listenOptions.eventOptions != null)
            eventOptions = listenOptions.eventOptions;
        if (listenOptions.ignoreCancelled != null)
            ignoreCancelled = listenOptions.ignoreCancelled;
    }
    let listenerOptions = { ignoreCancelled, priority: EventPriority.NORMAL };
    if (eventOptions) {
        listenerOptions.options = eventOptions;
    }
    let listener = new SingleHandlerEventListener(tevent, callback, listenerOptions);
    manager.addListener(listener);
    return listener;
}
export class SingleHandlerEventListener {
    constructor(event, cb, options) {
        this[sEventListenerData].handlerEntries[0] = [
            event,
            options?.priority ?? EventPriority.NORMAL,
            {
                options: options?.options,
