如何在 Discord 用戶輸入中搜索值並將其分配給 var？

Question

我正在嘗試搜索 Discord 用戶輸入附加到屬性（攻擊次數、攻擊技能、強度、韌性、保存）的整數，然后通過一些計算運行這些參數。

目前 function 在命令中使用 args 的順序：

！賠率 5 3 4 5 3

哪個有效，但我想要這樣的東西：

:賠率: 5 sk: 3 st: 4 t: 5 sv: 3

機器人將以任何順序在用戶輸入中搜索附加到這些屬性的值，並使用這些整數進行計算。

此外，如果屬性不存在，機器人將不會將它們包含在 output （或分配默認值）中，並通過添加沒有附加 integer 的附加單短語屬性（例如fnp或res ）然后添加另一個標准計算和 output。

這是我到目前為止所擁有的：

const { Message } = require('discord.js')
module.exports = {
    name: 'odds',
    aliases: ['stats', 'probability'],
    usage: '[#attacks (1 = auto hit)] [skill] [strength] [toughness] [save (7 = no save)]',
    description: 'What are the odds?',

    execute(message, args) {
        let attack = args[0]
        let skill;
        if (args[1]>=7) skill = 7;
        else skill = args[1];
        let strength = args[2]
        let toughness = args[3]
        let save;
        if (args[4]<=6) save = args[4];
            else save = 7;
        let hits = parseFloat((attack*((7-skill)/6)).toFixed(2))
        let hitSixes = parseFloat((attack*(1/6)).toFixed(2))
        let woundFactor; 
         if (strength>=(2*toughness)) woundFactor = 2;
        else 
        if (strength>toughness) woundFactor = 3;
        else
        if (strength==toughness) woundFactor = 4;
        else
        if (toughness>=(2*strength)) woundFactor = 6;
        else
        if (strength<toughness) woundFactor = 5;

        let wounds = parseFloat((hits*((7-woundFactor)/6)).toFixed(2))
        let woundSixes = parseFloat((hits*(1/6)).toFixed(2))
        let unsavedWounds = parseFloat(((wounds-(wounds*((7-save)/6))).toFixed(2)))

    message.channel.send(`On average you will make:\n${hits} successful hits (with ${hitSixes} sixes)\n${wounds} successful wounds (with ${woundSixes} sixes)\nGiving a total of ${unsavedWounds} unsaved wounds.`)
    }}

非常感謝任何和所有幫助！

// what you accept:
const inputs = {
    at: 0,
    sk: 0,
    st: 0,
    t: 0,
    sv: 0,
}

for (let i = 0, arg; arg = args[i]; i++) {
    const index = arg.indexOf(':'); // it must have an ":" as last character
    if (index === -1) {
        continue;
    }
    const keyword = arg.substr(0, index - 1); // get the word
    if (!inputs.hasOwnProperty(keyword)) { // check if it's an element of inputs
        continue;
    }
    if (i + 1 === args.length) { // make sure enough args are available
        continue;
    }
    inputs[keyword] = isNaN(args[i + 1]) ? 0 : +args[i + 1]; // make sure it's a number
    i++; // skip the next element
}

let attack = inputs.at;
let skill = inputs.sk >= 7 ? 7 : inputs.sk;
let strength = inputs.st;
let toughness = inputs.t;
let save = inputs.sv <= 6 ? inputs.sv : 7;
