javascript - Bot 将字符串返回到我没有指定的数字

Question

制作一个不和谐的机器人。不仅在 6 卷上获得“你赢了”，而且在 2 和 4 上也如此。我知道这不是最好的方法。它似乎并不关心是否random == 'insert string here' 或 random == 'insert int here'。

//Dice Roll Game
bot.on('message', (message) =>{  

    let diceNum = ['1','2','3','4','5','6'];
    let random = diceNum[Math.floor(Math.random() * diceNum.length)];

    if(message.content == '!roll') {
        message.reply('You rolled a' + ' ' + random + '!');
    }

    if(random == 6){
        message.reply('You win!');
    }
});

我看到您的代码的主要问题是:

1. You did not put your all of your dice-related code into the if-block checking if the message is the roll command.

   • This causes the bot to reply when the number "rolled" is 6 even when the command is not invoked.

2. You did not check whether the message came from a bot.

   • It would reply multiple times since you did not check whether the message came from your bot.

修复所有错误后，您的代码将如下所示:

//Dice Roll Game
bot.on('message', message => { // If theres only one parameter, you can omit brackets
    // Bot Check
    if(message.author.bot)return;

    // Even with useless parameters to the command, it will still run
    if(message.content.startsWith('!roll')) { 

        // Arrays are not needed

        // Gives a random int from 1 - 6, (~~) floors an integer 
        let random = ~~(Math.random() * 6) + 1; 

       message.reply(`You rolled a ${ random }!`); // ES6 Template Strings 

        // Please use strict equality signs to prevent bugs from appearing in your code
        if(random === 6){
            message.reply('You win!');
        }
    }

});

旁注:如果您不希望在您的 bot 消息前添加提及，请使用 message.channel.send 而不是 message.reply。
