PermissionChangeListener

This little library hooks into the PermissibleBase of all online players in order to detect permission changes and then broadcast them to all consumers using the PlayerPermissionsChangedEvent.

Usage

import me.blvckbytes.bbreflect.ReflectionHelper;
import me.blvckbytes.bbreflect.version.ServerVersion;
import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.plugin.java.JavaPlugin;

import java.util.List;

public class ExampleUsage extends JavaPlugin implements Listener {

  private PermissionChangeListener changeListener;

  @Override
  public void onEnable() {
    try {
      ReflectionHelper rh = new ReflectionHelper(ServerVersion.current());
      changeListener = new PermissionChangeListener(this, rh);

      getServer().getPluginManager().registerEvents(this, this);
    } catch (Exception e) {
      throw new RuntimeException(e);
    }
  }

  @Override
  public void onDisable() {
    if (changeListener != null)
      changeListener.cleanup();
  }

  @EventHandler
  public void onPermissionChange(PlayerPermissionsChangedEvent e) {
    List<String> added = e.getAdded(), removed = e.getRemoved(), active = e.getActive();
    Player player = e.getPlayer();

    // TODO: React to the event
  }
