How to fix permissions?

Hello, I am making a plugin which does not contain a command; this is a plugin which fires a firework in the air when a player logs in; but I am attempting to create a permission node. I have created the node in the yaml; it's bang.* but I require assistance in adding it into my code. I know what to do; but I do not know where... if(player.hasPermission("bang.*"){
}
Which I think is right... Someone help on where to put this :3 Thanks. Here is my code:

Code:java

package me.Schnel.EnterWithABang;
 
 
 
import org.bukkit.Bukkit;
 
import org.bukkit.Color;
 
import org.bukkit.FireworkEffect;
 
import org.bukkit.FireworkEffect.Type;
 
import org.bukkit.entity.Firework;
 
import org.bukkit.event.Listener;
 
import org.bukkit.plugin.java.JavaPlugin;
 
import org.bukkit.event.EventHandler;
 
import org.bukkit.event.player.PlayerJoinEvent;
 
import org.bukkit.inventory.meta.FireworkMeta;
 
 
 
public class Main extends JavaPlugin implements Listener {
 
 
 
    public void onEnable(){
 
        Bukkit.getServer().getPluginManager().registerEvents(this, this);
 
        getLogger().info("Plugin Enabled");
 
    }
 
 
 
    public void onDisable(){
 
        getLogger().info("Plugin Disabled");
 
    }
 
 
 
    @EventHandler
 
    public void onPlayerJoin (final PlayerJoinEvent pje) {
 
            Bukkit.getServer().getScheduler().scheduleSyncDelayedTask(this, new Runnable(){
 
                public void run(){
 
 
 
                    Firework f = (Firework) pje.getPlayer().getWorld().spawn(pje.getPlayer().getLocation(), Firework.class);
 
 
 
                    FireworkMeta fm = f.getFireworkMeta();
 
                    fm.addEffect(FireworkEffect.builder()
 
                            .flicker(true)
 
                            .trail(true)
 
                            .with(Type.BALL)
 
                            .with(Type.BALL_LARGE)
 
                            .with(Type.STAR)
 
                            .with(Type.BURST)
 
                            .withColor(Color.OLIVE)
 
                            .withColor(Color.FUCHSIA)
 
                            .withFade(Color.LIME)
 
                            .withFade(Color.ORANGE)
 
                            .build());
 
                    fm.setPower(1);
 
                    f.setFireworkMeta(fm);
 
                }
 
            }, 10);
 
 
 
    }
 
 
 
}
 
 

So in summary, I would like it so that it only fires the firework if the player has the permission node 'bang.*'

 

You should really have it as a specific node (bang.login-firework, etc), and then make that node a child node of bang.* in your plugin.yml

As for checking, it's just Player#hasPermission("string");
