Getting A region name from a sign using WorldGuard

Hi.

The title of what I am going to ask pretty much says it all.

How would you get a WorldGuard region name from the text on a sign?

Thx to Paul O'Reilly for helping me to get a region name from a users location.
Mabey you could help me again to get the name from a sign.

Any help from anyone else will still be greatly appreciated.

 

You can try look here:
http://wiki.sk89q.com/wiki/WorldGuard/Regions/API

...use getApplicableRegions for position (Vector) of sign

 

I know that I've looked at it before. But I Still cant seem to figure out how to get it to work.

This is my BlockListener class for the onSignChangeEvent

Code:

package me.drew1080.signprotect;
 
import org.bukkit.ChatColor;
import org.bukkit.Location;
import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.EventPriority;
import org.bukkit.event.Listener;
import org.bukkit.event.block.SignChangeEvent;
 
import com.sk89q.worldedit.Vector;
import com.sk89q.worldguard.LocalPlayer;
import com.sk89q.worldguard.bukkit.WorldGuardPlugin;
import com.sk89q.worldguard.protection.ApplicableRegionSet;
import com.sk89q.worldguard.protection.managers.RegionManager;
 
public class SignProtectBlockListener implements Listener{
   
      protected SignProtect plugin;
 
      SignProtectBlockListener(SignProtect plugin)
      {
        this.plugin = plugin;
      }
   
      @EventHandler(priority=EventPriority.MONITOR)
      public boolean onSignChange(SignChangeEvent event){
      if (event.getLine(0).equalsIgnoreCase("[PLOT]"));
        {
         
            Player player = event.getPlayer();
            Location loc = event.getBlock().getLocation();
            WorldGuardPlugin worldGuard = SignProtect.getWorldGuard();
            Vector pt = toVector(event.getLine(1)); // This also takes a location
            LocalPlayer localPlayer = worldGuard.wrapPlayer(player);
         
            RegionManager regionManager = worldGuard.getRegionManager(loc.getWorld());
            ApplicableRegionSet set = regionManager.getApplicableRegions(pt);
            return set.canBuild(localPlayer);
       
        }
      }
}

Heres my main class file:

Code:

package me.drew1080.signprotect;
 
 
import java.util.logging.Logger;
 
import org.bukkit.Server;
import org.bukkit.plugin.Plugin;
import org.bukkit.plugin.PluginManager;
import org.bukkit.plugin.java.JavaPlugin;
 
import com.sk89q.worldguard.bukkit.WorldGuardPlugin;
 
public class SignProtect extends JavaPlugin{
 
      private static Server server;
      Logger log = Logger.getLogger("Minecraft");
   
      public static WorldGuardPlugin getWorldGuard()
      {
        Plugin plugin = server.getPluginManager().getPlugin("WorldGuard");
 
        if ((plugin == null) || (!(plugin instanceof WorldGuardPlugin))) {
          return null;
        }
        return (WorldGuardPlugin)plugin;
      }
      public void onEnable(){
          registerEvents();
          getConfig();
          log.info("[SignProtect] SignProtect is enabled");
      }
        public void registerEvents() {
            PluginManager pm = getServer().getPluginManager();
            pm.registerEvents(new SignProtectBlockListener(this), this);
            }
      public void onDisable(){
          log.info("[SignProtect] SignProtect is disabled");
      }
}

and heres the error I get when I run it on the server:

Code:

I know that it returns a nullPointerException but even when I insert a null check it still return the same error.

 

You don't need player build flag...

Code:

ApplicableRegionSet set = regionManager.getApplicableRegions(pt);
return set.canBuild(localPlayer);

(Try read it if you copy it)

You need names of regions on player location...

Code:

//get set of all regions player are in
ApplicableRegionSet set = regionManager.getApplicableRegions(player.getLocation());
 
//test if player isn't only in global region
for (ProtectedRegion region : set) {
    if (region.getId() != "__global__") {
        // return name of region, or you can change line on sign...
        return region.getId();
    }
}

Sorry for bad english.​

Thx for that, I have never tried to implement anything from worldguard or worldedit before so this was all kinda new to me.

 

...yes, It been new to me too, but I working on Radiaiton plugin, and I use it here...
