I need help with a plugin

Could someone who has knowledge in creating plugins help me creating a plugin?

How I want it:

I want a command (/n) that when typing with the following format (/n doubt) appears in the chat of all the players as a doubt in which everyone can answer I also want to have a limit of using the command, every 3 minutes you can put a doubt

 

explain more

 

What I mean is a doubt channel in which everyone can participate, I want the player to use /n to post their question, I also want it to appear in everyone's chat log with blue letters Example:

/n how do i crawl a peak?

by entering this will appear in everyone's chat log

I'm going to see if I can give you a more advanced example haha I'm not that good with this

 

so u basically need a command that broadcasts a message in blue and has a task holding a delay for the /n command?

 

Something like that, that it is a channel of doubts in which they post a question and other players can answer that question also that every 2 minutes they can post a question.

 

ok i could probs do that just give me atleast two days im working on a few projects at once right now.

 

Ok

 

Avoid using Tasks where not necessary.

PHP:

// Command executed
this.cache[player.name] = time();

func get_last_execution_time(Player player) {
   return this.cache[player.name] ?? 0;
}

delta = time() - get_last_execution_time(player);

// Check if three minutes passed
if(delta > three_minutes) {
   // Execute command, update cache
}


For anyone who's confused - this is Pseudocode
