Solved Custom Signs problems!

This is my current code.
Why isn't it working??

Code:java

 
@EventHandler
    public void onSignChange(SignChangeEvent e){
        Sign s = (Sign) e.getBlock();
        if(s.getLine(0).equalsIgnoreCase("arenapvp")){
            s.setLine(0, "[Arena PVP]");
            s.update();
            e.getPlayer().sendMessage("Yay!");
        }
    }
    @EventHandler
    public void onInteract(PlayerInteractEvent Event) {
        Player player = Event.getPlayer();
        Block block = Event.getClickedBlock();
        if (block.getType() == Material.WALL_SIGN || block.getType() == Material.SIGN_POST) {
            Sign sign = (Sign) block.getState();
            if(sign.getLine(0).equalsIgnoreCase("[Arena PVP]")){
                player.sendMessage("HellO!");
                //more code
            }
        }
    }
 

 

did you register the events?

Here is my SignListener.class

Code:java

 
package main;
 
import org.bukkit.Material;
import org.bukkit.block.Block;
import org.bukkit.block.Sign;
import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.block.SignChangeEvent;
import org.bukkit.event.player.PlayerInteractEvent;
 
public class SignListener implements Listener {
    @EventHandler
    public void onSignChange(SignChangeEvent e){
        Sign s = (Sign) e.getBlock();
        if(s.getLine(0).equalsIgnoreCase("arenapvp")){
            s.setLine(0, "[Arena PVP]");
            s.update();
            e.getPlayer().sendMessage("Yay!");
        }
    }
    @EventHandler
    public void onInteract(PlayerInteractEvent Event) {
        Player player = Event.getPlayer();
        Block block = Event.getClickedBlock();
        if (block.getType() == Material.WALL_SIGN || block.getType() == Material.SIGN_POST) {
            Sign sign = (Sign) block.getState();
            if(sign.getLine(0).equalsIgnoreCase("[Arena PVP]")){
                player.sendMessage("HellO!");
                //more code
            }
        }
    }
}
 

And here is my onEnable in main class

Code:java

 
    @Override
    public void onEnable(){
        if(!getDataFolder().exists())
            getDataFolder().mkdir();
 
        if(getConfig() == null)
            saveDefaultConfig();
 
        new ArenaManager(this);
        ArenaManager.getManager().loadGames();
 
        getServer().getPluginManager().registerEvents(new GameListener(this), this);
        getServer().getPluginManager().registerEvents(new SignListener(), this);
    }

Do it like this:

Code:java

if(e.getLine(0).equalsIgnoreCase("arenapvp")){
            e.setLine(0, "[Arena PVP]");
            e.getPlayer().sendMessage("Yay!");
        }

No need to call the block, or update the sign.

 

Try this:

Code:java

Sign s = (Sign) e.getBlock().getState();
// In order for the sign to get the block, it needs to get the state that it's in in order to procede.

This isn't working either.

Code:java

public class SignListener implements Listener {
@EventHandler
public void onSignChange(SignChangeEvent e){
Sign s = (Sign) e.getBlock().getState();
if(s.getLine(0).equalsIgnoreCase("arenapvp")){
s.setLine(0, "[Arena PVP]");
s.update();
e.getPlayer().sendMessage("Yay!");
}
}
@EventHandler
public void onInteract(PlayerInteractEvent Event) {
Player p = Event.getPlayer();
Sign s = (Sign) Event.getClickedBlock().getState();
if (s.getType() == Material.WALL_SIGN || s.getType() == Material.SIGN_POST) {
if(s.getLine(0).equalsIgnoreCase("[Arena PVP]")){
p.sendMessage("HellO!");
//more code
}
 
}
}
}

I get this error
