yoni-mcscripts-lib/yoni/command/AsyncCommandQueue.js

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 { CommandQueueExecuteStatus } from "./CommandQueueExecuteStatus.js";
export class AsyncCommandQueue {
    sender;
    command;
    #status = CommandQueueExecuteStatus.executing;
    get status() {
        return this.#status;
    }
    #result;
    get result() {
        if (this.status === CommandQueueExecuteStatus.executing)
            throw new Error("command executing have not been done");
        return this.#result;
    }
    async resolveResult(commandResult) {
        if (this.#status !== CommandQueueExecuteStatus.executing) {
            return;
        }
        try {
            this.#result = await commandResult;
            this.#status = CommandQueueExecuteStatus.done;
        }
        catch (err) {
            this.reject(err);
            this.#status = CommandQueueExecuteStatus.failed;
        }
        if (this.#status === CommandQueueExecuteStatus.done)
            this.#resolveCallback(this.result);
        else
            this.#rejectCallback(this.result);
    }
    reject(err) {
        if (this.status === CommandQueueExecuteStatus.executing) {
            this.#status = CommandQueueExecuteStatus.failed;
            this.#result = err;
        }
    }

    constructor(sender, command, resolve, reject) {
        if (typeof sender?.runCommandAsync !== "function") {
            throw new TypeError("sender cannot runCommandAsync()");
        }
        this.sender = sender;
