Timers that perform actions on players

Hi, I'm pretty new to java and really new to developing plugins, and I have a really simple question. I'm making a test plugin, and all I want to do is have a timer that performs an action on all players every 2 or so seconds such as killing them or anything like that. I want it to happen to every player online without anyone executing any commands; it just keeps happening over and over. I know this is really simple, but I honestly searched around for like 50 minutes straight and couldn't find an answer. Thanks in advance for any help

 

Look at this tutorial to learn how create scheduled tasks. This code below is an example and kills all players every two seconds like you mentioned.

Code:java

//This code will only work in your main plugin class that extends JavaPlugin
//The 'this' is a reference the main plugin class
//If you're scheduling the task in another class you need to reference your main plugin class somehow
 
Bukkit.getScheduler().scheduleSyncRepeatingTask(this, new Runnable() {
    public void run() {
        for (Player player : Bukkit.getOnlinePlayers()) {
            if (!player.isDead()) {
                player.setHealth(0);
            }
        }
    }
}, 0, 40); //Every second is equal to 20 ticks so this would fire every 2 seconds after a 0 tick delay

 

Thank you so much! This seems to be exactly what I'm looking for.

I'm having strange issues with this; it's giving me weird squiggly brace syntax errors. Here's how the whole class looks:

Code:java

package com.gmail.eyedjellyfish.test;
import org.bukkit.entity.Player;
import org.bukkit.Bukkit;
import org.bukkit.plugin.java.JavaPlugin;
 
public class test extends JavaPlugin{
 
public void onEnable() {
getLogger().info("Hi.");
}
 
public void onDisable() {
getLogger().info("Bai");
//error on the following brace
}
 
Bukkit.getScheduler().scheduleSyncRepeatingTask(this, new Runnable() {
public void run() {
for (Player player : Bukkit.getOnlinePlayers()) {
if (!player.isDead()) {
player.setHealth(0);
}
}
}
}, 0, 40);
 
//error on the following brace
}

You need to put the scheduler inside a method...
Move it inside your onEnable()

 

Oh wow... epic fail by me. Thanks.
