掷骰子。 DND,将数组中的数字加在一起
Dice roll. DND, add numbers from an array together
所以我为龙与地下城创建了一个基本的掷骰子 dicord 机器人。
我目前使用的代码可以掷任何类型的骰子,(例如“roll xdy”“roll 1d20”,“roll 100d100”)
当有人发送匹配的消息时,它会输出结果。
我的问题是我想将这些数字加在一起并显示结果总数,但我不确定如何到达那里。
// Run dotenv
require('dotenv').config();
const { any } = require('async');
const Discord = require('discord.js');
const client = new Discord.Client({ intents: ["GUILDS", "GUILD_MESSAGES"] });
client.on('messageCreate', msg => {
z = msg.content;
matches = z.match(/\d+/g);
x = matches[0];
y = matches[1];
if (msg.content === 'ping') {
msg.reply('pong');
}
if (msg.content == 'roll ' + x + 'd' + y) {
function rollDie(sides) {
if (!sides) sides = 6;
return 1 + Math.floor(Math.random() * sides);
}
function rollDice(number, sides) {
var total = [];
var number = x;
var sides = y;
while (number-- > 0) total.push(rollDie(sides));
return total;
}
msg.reply("result: " + rollDice());
console.log(rollDice())
}
});
client.login(process.env.DISCORD_TOKEN);
应该这样做。
Reduce 将回调函数应用于给定数组的每个元素,因此您可以使用它来添加数组的所有值并报告它。
将数组 'totalArr' 传递给此函数应该会得到数组中所有数字的总和
Javascript
const rollTotal = function (totalArr) {
const startingRoll = 0;
const subTotal = totalArr.reduce(
(previousValue, currentValue) =>
previousValue + currentValue,
startingRoll
);
return subTotal;
};
测试
console.log(rollTotal([1, 2, 3]));
输出=6
好像您在声明变量时没有使用 let
或 var
(z
、matches
、x
和 y
) .没有理由再使用 var
了。我使用 toLowerCase and trim methods, and wrapped all the logic in an if (msg) { .. }
to scrub input a bit. You had parameters for the rollDice
function but then were just pulling from the variables you created and not using the parameters, so I modified that. I used the reduce 方法对数组求和。我更改了一些变量名称以使其更具描述性(例如 z
更改为 msgContent
)并在更多可用的地方使用它们。
在您的 rollDie
函数中,您给出的默认模具边数为 6,但由于 if
语句包装它,调用该函数的唯一方法是边数是专门选择的。所以我修改了这个,这样如果有人只想掷 3 个 6 面骰子,他们可以输入“Roll 3”。在报告骰子掷骰时,我使用了 join 方法,因此它们将以逗号和 space 分隔列表而不是数组显示。
const { any } = require("async");
const Discord = require("discord.js");
const client = new Discord.Client({ intents: ["GUILDS", "GUILD_MESSAGES"] });
client.on("messageCreate", (msg) => {
if (msg) {
let msgContent = msg.content.trim().toLowerCase(),
matches = msgContent.match(/\d+/g),
numDice = matches[0],
numSides = matches[1],
diceResults = [];
if (msgContent === "ping") {
msg.reply("pong");
}
if (
msgContent === "roll " + numDice ||
msgContent === "roll " + numDice + "d" + numSides
) {
function rollDie(sides) {
if (!sides) sides = 6;
return 1 + Math.floor(Math.random() * sides);
}
function rollDice(number, sides) {
let diceArray = [];
while (number-- > 0) diceArray.push(rollDie(sides));
return diceArray;
}
function calcDiceTotal(diceArray) {
return diceArray.reduce(
(previousValue, currentValue) => previousValue + currentValue,
0
);
}
diceResults = rollDice(numDice, numSides);
msg.reply(
"ROLLING... " + diceResults.join(", ") +
" || TOTAL: " + calcDiceTotal(diceResults);
);
}
}
});
client.login(process.env.DISCORD_TOKEN);
输出应如下所示:"ROLLING... 3, 1, 6, 3, 5 || TOTAL: 18"
这是按预期工作的最终机器人程序代码,使用了上面的修复程序并对其进行了调整,因此当有人输入任何其他消息时机器人程序不会中断。
看起来效果不错!
