Solved Sign not changeing line on right click

Code:java

package me.duuckky.events;
 
import org.bukkit.ChatColor;
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.Action;
import org.bukkit.event.player.PlayerInteractEvent;
 
public class SignInteract implements Listener {
 
    @EventHandler
    public void onPlayerInteract(PlayerInteractEvent e) {
        Player player = e.getPlayer();
        Block b = e.getClickedBlock();
        Action action = e.getAction();
 
        // Null Check to Prevent Null Pointer Exception
        if (e.getClickedBlock() == null) {
            return;
        }
 
        // If they click a sign
        if (action == Action.RIGHT_CLICK_BLOCK
                && b != null
                && (b.getType() == Material.SIGN_POST || b.getType() == Material.WALL_SIGN)) {
            Sign sign = (Sign) b.getState();
            // If the sign has these lines
            if (sign.getLine(0).equals("Test")
                    && sign.getLine(1).equals(ChatColor.GREEN + "Test2")) {
                // Tell the player it works
                player.sendMessage(ChatColor.RED + "Sign!");
                sign.setLine(0, "§c>" + String.valueOf(sign.getLine(0)) + "§c<");
            }
        }
    }
}
 

This is the code when i right click the sign, it displays "Sign!" But doesn't add ">" or "<" around the line

 

Any exceptions or anything?

Also you can remove && b !=null

You already did the null check.

 

Bukkit can be weird about signs sometimes. Try sticking the sign.setLine() call in a scheduler with Bukkit.getScheduler().runTask().

 

ShadyPotato Since he is modifying the state itself, shouldn't he just call update() on it?

 

Yeah, that would do it. Totally forgot about that little method. I was thinking of updating the sign during a SignChangeEvent when I suggested using a scheduler.

 

Thanks!
