[Tutorial] Bukkit Plugin Programmieren - GL, Befehle und Listener

@Johannes_C25

Habe echt keine Ahnung, warum es in der Klasse nicht funktioniert. Im Listener funktioniert es doch auch <.<

[Johannes_C25]

@Panjab

Weil in deinem Listener wahrscheinlich etwas in dieser Art steht:

Main plugin;
public Listener (Main plugin) {
    this.plugin = plugin;
}

Aber genau das fehlt in der Command Klasse.

Und ich würde dir wirklich vorschlagen eine Klasse einmal zu erstellen, die du dann öfters benutzt. Weil momentan ist das (meiner Meinung nach) ziemlich Resourcen verschwenderisch...

[Panjab]

@Johannes_C25

Selbst wenn ich das einbaue, bringt es leider auch nix

[dainless]

Sollte man das

int seconds = Integer.parseInt(st);

bei Handyhackers Problem nicht in einen TryCatch-Block schreiben, weil wegen Fehler?

[Johannes_C25]

@dainless

Jup... sollte man.

@Panjab

Wie sieht die Klasse dann aus? Wie rufst du sie auf? Ist es dann vielleicht eine andere Fehlermeldung?

loadConfig() ist ne Methode

    public boolean loadConfig() {
        
        this.config = getConfig();
        
        this.config.options().copyDefaults(true);
        saveConfig();
        
        if (!new File(getDataFolder() + "src/config.yml").exists());
        saveDefaultConfig();
        
        return true;
    }

Listener:

    Main plugin;
    
    public ZoneListener(Main instance) {
        
        plugin = instance;
        
    }
    
    static int zone_ID;

    
    @Event Handler
    public void onPlayerInteract(PlayerInteractEvent event) {
        
        final Player player = event.getPlayer();
        
        if (ModSettings.createOn.contains(player) && ModSettings.step1.contains(player)) {
            
            if (event.getAction() == Action.LEFT_CLICK_BLOCK && player.getItemInHand().getType() == Material.STICK) {
                
                try {
                    
                    plugin.l1 = event.getClickedBlock().getLocation();
                    player.sendMessage("");
                    player.sendMessage(ChatColor.DARK_GREEN + "Position 1: " + Throws.showBlockCoords(plugin.l1));
                    
                    event.setCancelled(true);
                    int loc1_x = plugin.l1.getBlockX();

Und alle Exceptions sind NullPointerException's welche auftreten, sobald irgendwas mit der Datei gemacht wird.

@Panjab

public ZoneListener(Main instance) {
        
        plugin = instance;
        
    }

Das hast du im Listener, aber nicht im Command Klasse.

[Panjab]

@Johannes_C25 Wie gesagt, selbst wenn ich das nutze, funktioniert es nicht :/

[Johannes_C25]

@Panjab

Bau es ein und zeig mir dann mal deinen Code... und schau, ob es vielleicht eine andere Fehlermeldung gibt.

[Panjab]

@Johannes_C25

Mit dieser Methode wirft es eine NullPointerException für die Zeile if (args.length == 2) <.<

            if (args[0].equalsIgnoreCase("delzone")) {
                if (args.length == 2) {
