Check if command is executed

Question

I have a problem with my restriction system for commands.
The message 'you don't have permission' will only run once (when you don't have the role). I'm aware that if you don't set a var (in this case checkrole) the code will be executed once however, I don't know how to check when a command is executed.

So I could do something like this:

if  (command === ' ') {
    checkrole = false
}

Code of interest:

if (!message.member.roles.some(r => ["someone"].includes(r.name.toLowerCase())) && checkrole === false) {
    checkrole = true;
    return message.channel.send('Sorry, but you do not have the **permissions** to do that.');
  }

(var checkrole is defined - it begins as false (var checkrole = false;))

Kind regards, Ruben

Answer 1

Usually if you want to use commands you need a prefix. Once you chose that, you know that the content of the message (Message.content) will start with prefix + command. So you could write it like this:

// Assuming that:
// var prefix = '-'; for example
if (message.content.startsWith(prefix + "mycommand")) {
  checkrole = false;
}

Although this works, there are more efficient ways to use commands, especially if you'll need to use arguments and so on...
