AFK counter

Hi, I'm trying to detect when a player is idle for 5 minutes in my plugin. But I don't know how or where to put the code, as everything so far in my plugin is triggered by events.

I also am not sure about what logic I should use. I can either record the player's location every 10 seconds or so, and compare it to the last recorded position. If the positions are the same 30 times in a row, the player is afk. Or I can have a counter that is reset on every PlayerMoveEvent, and if the counter reaches 5 mins, the player is afk. Or perhaps there is a better solution...

Thanks!

 

Scheduling something to happen every few seconds sounds like a good place to start. What I would do is store all the online players in a HashMap along with an integer of how many seconds they've been AFK. Have a server-wide repeating task to increase every player's integer by 1 every second, but listen to PlayerMoveEvent and reset that player to 0. Of course you can have things like announcing "player is now AFK" inside the timer loop itself.

 

I hate to be "that guy", but could you show me an example of how to do this?

I would rather reset the players "last moved time" to System.currentTimeMillis() and have a schedular that repeats every 30 seconds or so, if the "last moved time" is greater than the configured value, kick the player

 

What about simply making a Map<String, Integer>, setting the String to the player's name and the Integer to how long they've not moved, and using a scheduler that repeats every second?

May or may not be what you need or want, but this is one way to do it. Tailor it to your needs.

Code:

public class AFKCheck extends JavaPlugin implements Listener {
    private static ConcurrentHashMap<String, Integer> times = new ConcurrentHashMap<String, Integer>();
    public static AFKCheck instance;
    private static int secondsToAFK;
    
    public void onEnable() {
        instance = this;
        
        new AFKListener();
        
        Bukkit.getScheduler().scheduleSyncRepeatingTask(this, new Runnable() {
            public void run() {
                for (Player player : Bukkit.getOnlinePlayers()) {
                    int time = times.containsKey(player.getName()) ? times.get(player.getName()) : 0;
                    times.put(player.getName(), time+1);
                }
            }
        }, (long)0, (long)20);
    }
    
    public static boolean isAFK(Player player) {
        return (times.containsKey(player.getName())) ? (times.get(player.getName()) >= secondsToAFK) : false;
    }
    
    public static int getTime(Player player) {
        return (times.containsKey(player.getName())) ? times.get(player.getName()) : 0;
    }
    
    public static void setTime(Player player, int time) {
        times.put(player.getName(), time);
    }
    
    public class AFKListener implements Listener {
        public AFKListener() {
            Bukkit.getPluginManager().registerEvents(this, AFKCheck.instance);
        }
        
        @EventHandler
        public void onPlayerMove(PlayerMoveEvent event) {
            AFKCheck.setTime(event.getPlayer(), 0);
        }
    }
}
