import java.util.logging.Logger;
import org.bukkit.ChatColor;
import org.bukkit.Location;
import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.block.BlockBreakEvent;
import org.bukkit.event.block.SignChangeEvent;
import org.bukkit.event.player.PlayerInteractEvent;

import org.bukkit.plugin.java.JavaPlugin;

public class Signs extends JavaPlugin implements Listener {
public final Logger logger = Logger.getLogger("Minecraft");
public static Signs plugin;
public final HashMap<Location, String> signs = new HashMap<Location, String>();
private String prefix;

@Override
public void onEnable() {
PluginDescriptionFile pdfFile = this.getDescription();
this.logger.info(pdfFile.getName() + " Version " + pdfFile.getVersion() + " Has Been Enabled!");
{
this.prefix = (ChatColor.DARK_GRAY + "[" + ChatColor.GREEN + "BCKit" + ChatColor.DARK_GRAY + "] ");
getLogger().info("has been enabled");
}
}

@Override
public void onDisable() {
PluginDescriptionFile pdfFile = this.getDescription();
this.logger.info(pdfFile.getName() + " Has Been Disabled!");

}

@EventHandler
public void onSignChange(SignChangeEvent event) {
if(event.getPlayer().isOp()) {
if(event.getLine(0).equalsIgnoreCase("[BCKit]"))
if(event.getLine(1).equalsIgnoreCase("Regular"))
signs.put(event.getBlock().getLocation(), event.getPlayer().getName());
event.getPlayer().sendMessage(this.prefix + " Kit Sign created."); }

}

@EventHandler
public void onBlockBreak(BlockBreakEvent event) {
if (signs.containsKey(event.getBlock().getLocation())
&& !signs.containsValue(event.getPlayer().getName())) {
event.setCancelled(true);
} else {
signs.remove(event.getBlock().getLocation());
}
}

@EventHandler
public void onPlayerInteract(PlayerInteractEvent event) {
Player player = event.getPlayer();
