Giving roles on discord - discord

Question

I'm making a discord murder mystery bot.
const Discord = require('discord.js');
const client = new Discord.Client();
client.on("message", (message) => {
msg = message.content.toLowerCase();
if (message.author.bot) {
return;
}
mention = message.mentions.users.first();
if (msg.startsWith("kill")) {
if (mention == null) {
return;
}
message.delete();
mention.send('you are dead');
message.channel.send("now done");
}
});
client.login('my token');
What would I add to the code so after the person who was tagged got there role changed from alive to dead?

Answer 1

// First, make sure that you're in a guild
if (!message.guild) return;
// Get the guild member from the user
// You can also use message.mentions.members.first() (make sure that you check that
// the message was sent in a guild beforehand if you do so)
const member = message.guild.members.cache.get(mention.id);
// You can use the ID of the roles, or get the role by name. Example:
// const aliveRole = message.guild.roles.cache.find(r => r.name === 'Alive');
const aliveRole = 'alive role ID here';
const deadRole = 'dead role ID here';
// You can also use try/catch with await if you make the listener and async
// function:
/*
client.on("message", async (message) => {
// ...
try {
await Promise.all([
member.roles.remove(aliveRole),
member.roles.add(deadRole)
]);
} catch (error) {
console.error(error);
}
})
*/
Promise.all([
member.roles.remove(aliveRole),
member.roles.add(deadRole)
]).catch(console.error);
The Promise.all means that the promises for adding and removing the roles are started at the same time. A promise is an object that can resolve to a value or reject with an error, so the .catch(console.error) logs all errors. I recommend that you handle errors for message.delete(), mention.send('you are dead'), and message.channel.send("now done") as well.
For more information on member.roles.remove() and member.roles.add(), see the documentation for GuildMemberRoleManager.
