How do I cancel out particles?

Code:

Code:

package me.SergeantBud;

import org.bukkit.Bukkit;
import org.bukkit.ChatColor;
import org.bukkit.command.Command;
import org.bukkit.command.CommandSender;
import org.bukkit.entity.Entity;
import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.player.PlayerJoinEvent;
import org.bukkit.permissions.Permission;
import org.bukkit.plugin.java.JavaPlugin;

public class Particles extends JavaPlugin implements Listener {
    public Permission playerPermission = new Permission("Particles.heart");
  
    public void onEnable() {
        this.getLogger().info("[Particles] Particle Effect Being Enabled...");
       }
  
    public void onDisable() {
        this.getLogger().info("[Particles] Particle Effect Being Disabled...");
    }

  
  
  
      public boolean onCommand(final CommandSender sender, Command cmd, String label, String[] args) {
           if (cmd.getName().equalsIgnoreCase("heart") && sender instanceof Player) {
             if (!sender.hasPermission("Particles.heart")) {
                 sender.sendMessage(ChatColor.RED + "[Particles]" + ChatColor.GRAY + " You Do Not Have Access To Use This Plugin!");
             }
             if (sender.hasPermission("Particles.heart")) {
                  Bukkit.getServer().getScheduler().scheduleSyncRepeatingTask(this, new Runnable() {
                    public void run() {
                        ParticleEffect.HEART.display(((Entity) sender).getLocation().add(0, 2, 0), 15, 0, 0, 0, 10, 10);
                        }
                    }
                , 0, 15);
                     sender.sendMessage(ChatColor.RED + "[Particles]" + ChatColor.GRAY + " Heart Particles Enabled!");
                 }
         }  
      
      
    return true;
              
       }
}

plugin.yml:

Code:

name: Particles
main: me.SergeantBud.Particles
version: 1.0
commands:
   heart:
      description: Particlesss
      usage: /<command>


permissions:
    Particles.heart:
        description: Allow Use Of All Particles
        default: op

Problem: I don't know how to stop the particles .-.
Anything else: Can anyone link me to a good forum/site where I can learn more about particles and how to create them? Thanks

 

Thanks, I'll look into packets!
