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。

export class CommandList {
    #commands = [[], [], [], [], []];
    #indexes = [0, 0, 0, 0, 0];
    #count = [0, 0, 0, 0, 0];
    hasNext() {
        for (const prio of [0, 1, 2, 3, 4]) {
            if (this.#count[prio] > 0)
                return true;
        }
        return false;
    }
    next() {
        let nextCommand = null;
        for (const prioIndex of [0, 1, 2, 3, 4]) {
            if (this.#count[prioIndex] > 0) {
                const index = this.#indexes[prioIndex];
                nextCommand = this.#commands[prioIndex][index];
                this.#indexes[prioIndex] += 1;
                this.#count[prioIndex] -= 1;
                break;
            }
        }
        if (!nextCommand)
            throw new Error("no next command");
        return nextCommand;
    }
    add(prio, command) {
        const prioIndex = prio - 1;
        this.#commands[prioIndex].push(command);
        this.#count[prioIndex] += 1;
    }
    count() {
        return this.#count.reduce((a, b) => a + b);
    }
}
