# Frequently Asked Questions

In this page, some very basic, frequently-asked questions are answered. It's important to understand that these examples are generic and will most likely not work if you just copy/paste them in your code. You need to understand these lines, not just blindly shove them in your code.

# Code Examples

# Bot and Bot Client

// Set the bot's "Playing: " status (must be in an event!)
client.on("ready", () => {
    client.user.setActivity("my code", { type: "WATCHING"})
})
// Set the bot's online/idle/dnd/invisible status
client.on("ready", () => {
    client.user.setStatus("online");
});
// Set the bot's presence (activity and status)
client.on("ready", () => {
    client.user.setPresence({
        activities: [{ 
          name: "my code",
          type: "WATCHING"
        }],
        status: "idle"
    })
})

Note: You can find a list of all possible activity types here.

client.on("ready", () => {
    client.user.setActivity("my code", { type: "STREAMING", url: "https://www.twitch.tv/an_idiots_guide" })
})

# Users and Members

// Get a User by ID
client.users.cache.get("user id here");
// Returns <User>
// Get a Member by ID
message.guild.members.cache.get("user ID here");
// Returns <Member>
// Get a Member from message Mention
message.mentions.members.first();
// Returns <Member>, if there is a mentioned member
// Send a Direct Message to a user
message.author.send("hello");
// With Member it works too:
message.member.send("Heya!");
// Mention a user in a message
message.channel.send(`Hello ${message.author.toString()}, and welcome!`);
// or
message.channel.send("Hello " + message.author.toString() + ", and welcome!");
// Restrict a command to a specific user by ID
if (message.content.startsWith(`${prefix}commandname`)) {
    if (message.author.id !== "A user ID") return;
    // Your Command Here
}
message.guild.members.fetch(message.author)
  .then(member => {
    // The member is available here.
  })
  .catch(() => {
    // When an error occurs.
  })

# Channels and Guilds

// Get a Guild by ID
client.guilds.cache.get("the guild id");
// Returns <Guild>
// Get a Channel by ID
client.channels.cache.get("the channel id");
// Returns <Channel>
// Get a Channel by Name
message.guild.channels.cache.find(channel => channel.name === "channel-name");
// returns <Channel>
// Create an invite and send it in the channel
// You can only create an invite from a GuildChannel
// Messages can only be sent to a TextChannel
message.guild.channels.cache.get('<CHANNEL ID>').createInvite().then(invite =>
    message.channel.send(invite.url)
);

# Messages

// Editing a message the bot sent
message.channel.send("Test").then(sentMessage => sentMessage.edit("Blah"));
// message now reads : "Blah"
message.channel.messages.fetch("352292052538753025")
  .then(message => {
    // do something with it
    // Check if the author of the message is the bot
    if (message.client.user.id !== message.id) return console.log("I'm not the author of that message!");
    // Edit the message
    message.edit("This fetched message was edited");
  });
