Message Command

To invoke a message command, user need to meets two criteria.

Mention or Global Prefix
Command Name and Arguments

Note: This is similar to discord.py's cogs

Message Center

const mcenter = new MessageCenter(client, { prefixes: ["simp"] });

In this example, our bot will only listen to message with prefix simp

You can also disable prefix and make the bot invoke everytime it is mentioned

WARNING

Appropriate Intents must be used, otherwise your bot won't give any reaction!

class MainCog extends CogMessageClass {
    // constructor omitted

    @MessageCommand({
        // This can be omitted, the decorator will use `name` from function name
        // name: "ping",
        aliases: ["ing"],
        description: "pong!",
    })
    async ping(msg: Message, strp: string) {
        await msg.reply("pong!");
    }
}

User can invoke ping command by sending simpping or simping

strp (Stripped Content) is message.content that removed prefix or mentions and command name

For example

// Command: play (using prefixes: ["simp"])
"simpplay The Rumbling"
// strippedContent is equal to
"The Rumbling"

// Command: submit (using mention: true)
"<@bot_id> submit cancel_1112 ```py\nimport os; os.system('sudo reboot');```"
// strippedContent is equal to
"cancel_1112 ```py\nimport os; os.system('sudo reboot');```"

message.content is remained unmodified, you can access full message there too
