(discord.js) 如何设置命令的时间限制？答案

【问题标题】：(discord.js) How to set a time limit on a command?(discord.js) 如何设置命令的时间限制？

【问题描述】：

我正在尝试为我的服务器创建一个法官机器人，它将赋予使用命令的人“原告”角色，并赋予他们提到的人“被告”角色。除了可以同时开始多个试验之外，一切都按预期完美运行。就像如果有人使用该命令，它使他们成为原告，第二人成为被告，如果第三人对第四人使用该命令，他们也将成为被告和原告。我想做到这一点，当命令的事件正在播放时，服务器中的其他任何人都无法使用该命令，直到第一次试用结束。我试图为整个服务器赋予“陪审团”角色并使它成为这样，如果有人拥有“陪审团”角色，他们就无法使用该命令，但我永远无法让它发挥作用。我还尝试为命令设置时间限制，但这也根本不起作用。我不知道如何让这个工作，任何建议表示赞赏！谢谢！！！

client.on("message", message => {
   
    const args = message.content.slice(prefix.length).trim().split(/ +/g);
    const command = args.shift().toLowerCase();

    if (command === "sue") {
       let member1 = message.mentions.members.first();
       message.member.roles.add("797738368737345536")
       member1.roles.add("797738235715256331");
       message.guild.members.cache.forEach(member => member.roles.add("797743010346565672"))
       message.channel.send("Court is now in session.")
       client.channels.cache.find(channel => channel.name === 'courtroom').send( + " **All rise.**"); 
       client.channels.cache.find(channel => channel.name === 'courtroom').send("Plaintiff, you have 2 minutes to state your case.");  
       setTimeout(function(){

        client.channels.cache.find(channel => channel.name === 'courtroom').send("Thank you. The court may be seated as we turn to the jury for their verdict.");   
    }, 240000);

    const Responses = [
        "The Jury hereby finds you.... **GUILTY!** You will be sentanced to 10 minutes in jail.",

    }, 250000);

    setTimeout(function(){

    }, 850000);

    }  
    
});

【解决方案1】：

您可以创建一个文件，这样当文件存在时，任何人都无法使用该命令。

const fs = require("fs");

if (command_gets_executed) { // If the command gets executed

 if (fs.existsSync("./commandAlreadyUsed")) { // Checking if the file exists

  // YOUR CODE - When the command should not be usable

 } else {

  fs.writeFileSync("./commandAlreadyUsed"); // Creating the file

  // YOUR CODE - When nobody else used the command before

 }
 

}

如果您希望该命令再次可用，只需使用fs.unlinkSync("./commandAlreadyUsed")。
