Command cooldown

Hey people, I'm currently working on my local chat plugin. Everything is working good but I'd like to add one thing.

Currently, people are using the broadcasting command like crazy. I want to put some kind of cooldown on this, so that they can only use it, say, every 2 minutes. Now, I honestly have no idea how to create something like this so I'm asking you people

Thanks.

 

Java timer class might do.

 

No need for a timer, just record the current time (System.currentTimeMillis() ) every time a player is trying to use this broadcast command. Next time the player sends this command check the time difference between the current time and the time you stored before (System.currentTimeMillis()-oldTime>2*60*1000) to see if the 2 min interval has passed.

 

This is the best way. And if you are smart you can program it so that it tells them how much longer they need to wait too.

 

Thanks, I think I understand what you are saying. Still one thing though, if I store it in a variable named "time" that one would apply to all players, right? How do I make a variable that only applies to one username? I'm just guessing it has something to do with arrays. But I have no idea tbh. (Yes, java noob here)

 

You need to make a Map object that maps a player to its time variable. something like that:

Code:

class X extends JavaPlugin {
   Map<Player,Long> playerTimes = new HashMap<Player,Long>();

...

   onPlayerCommand(...) {
      Long oldPlayerTime = playerTimes.get(player); // find the last time the player used the command
      long curTime = System.timeInMillis();
      long diff = curTime - oldPlayerTime;
      .....
      playerTimes.put(player, curTime); // update the time variable for the player
   }

You also need to check that outPlayerTime is not null
Lookup the docs for Map and HashMap for more info

 

Thank you very much for your help! Got it working the way I wanted it to

 

Could someone actually make a plugin for this? It'd need a config file, but in the config file you just put any command and then how long the cooldown is.

Just got Zeus and we want to give the lightning to specific players, but need to add a cooldown coz it can be spammed right now...
