Plugin saying I'm not looking at sign but I am

So I made a newer version of my personal plugin where you can change the line of a sign. I added color support and spacing, but now it doesn't find the sign I'm looking at. I can't figure out why it's not finding it and that's why I'm here. If you can help, please.

Code:java

package com.conectedpvp.signchanger;
 
import org.bukkit.ChatColor;
import org.bukkit.Material;
import org.bukkit.block.Block;
import org.bukkit.block.BlockState;
import org.bukkit.command.Command;
import org.bukkit.command.CommandSender;
import org.bukkit.entity.Player;
import org.bukkit.block.Sign;
import org.bukkit.plugin.java.JavaPlugin;
 
public class SignChanger extends JavaPlugin {
    public void sendMessage(String text,CommandSender player) {
        player.sendMessage(ChatColor.GREEN + "[SignChanger] " + ChatColor.GOLD + text);
    }
 
    public boolean onCommand(CommandSender sender, Command cmd, String label, String[] args){
        if (cmd.getName().equalsIgnoreCase("changeline") && args.length >= 2) {
            if (sender instanceof Player) {
                Player player = (Player) sender;
                if (player.hasPermission("SignChanger.changeline")) {
                    @SuppressWarnings("deprecation")
                    Block block = player.getTargetBlock(null, 200);
                    if (block.equals(Material.WALL_SIGN) || block.equals(Material.SIGN_POST)) {
                        StringBuilder buffer = new StringBuilder();
                        for (int i = 1; i < args.length; i++) {
                            buffer.append(' ').append(args[i]);
                        }
                        String newb = buffer.toString().replaceAll("(&([a-f0-9]))", "\u00A7$2");
                        if (newb.length() <= 15) {
                            int num = Integer.parseInt(args[0])+1;
                            if (num <= 5 || num > 0){
                                BlockState state = block.getState();
                                Sign sign = (Sign)state;
                                sign.setLine(num, newb);
                                sign.update(true);
                            } else sendMessage("There are only 4 lines on one sign!",sender);
                        } else sendMessage("There are only 15 character spots one line!",sender);
                    } else sendMessage("Please look at a sign to run this command!",sender);
                } else return false;
            } else sendMessage("You must be a player to run this command!",sender);
        }
 
        return true;
    }
}
[/i]

 

Code:java

if (block.equals(Material.WALL_SIGN) || block.equals(Material.SIGN_POST)) {

this needs to be:

Code:java

if (block.getType(Material.WALL_SIGN) || block.getType(Material.SIGN_POST)) {

 

That doesn't have any arguments, but I did this, would it work?

Code:java

block.getType().equals(Material.WALL_SIGN)

 

That's right, sorry, I'm used to block.getType() == Material.WALL_SIGN, so I forgot you need to input the equals() if you omit the"=".
