Plugin na RTP wywala dziwne błędy

KaPeGie · 30 Marca 2019

Witam,

ostatnio zacząłem pisać pluginy i podjąłem się zadania zrobienia pluginu na RandomTP.

Niestety po napisaniu wywala mi błędy w konsoli i wyłącza mi się wtedy serwer.

Nie ma żadnych błędów w eclipse.

PLUGIN:

MAIN:

package com.gmail.kapegie26.KPGrtp;

import org.bukkit.plugin.java.JavaPlugin;

import com.gmail.kapegie26.KPGrtp.Commands.Commands;

public class Main extends JavaPlugin{

	@Override
	public void onEnable() {
		
		//Config
		getConfig().options().copyDefaults(true);
		saveConfig();
		
		//Commands
		getCommand("randomtp").setExecutor(new Commands());
		
	}
	
	@Override
	public void onDisable() {
		
	}
	
}

COMMANDS:

	    }

no blad to taki troche niepypowy i zwiazany z gsonem :l , ogolnie jest tak ze mowisz do gsona aby zrobil liste a tu czary mary jest String ...

kiedy wywala blad ?

nie wiem czego to wina :l ale 2 rzeczy ktore mozesz zrobic i ktore moga sypac .
- 1.8... czy t wymaga komentarza ? kurde ludzie mamy 2019 rok i wersje 1.13 !!! 1.13 to bedzie dobre 4 AKTUALIZACJE w stosunku do 1.8

- mozliwe ze cos skopane w pliku konfiguracyjnym , ale nie wiem , raczej bukkitowy yaml jest idioto odporny ale kto wie , jak to jest ten blad to sprobuj wygenerowac config kodem

- DEBUGUJ masz blad debugujesz i widzisz ktora linijka sypie i co sie poklei dzieje

teraz czepie sie kodu

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/command/CommandExecutor.html

if (cmd.getName().equalsIgnoreCase("randomtp")) {

cmd.getName() <- metoda zwraca NAZWE komendy a jako nazwe mam na mysli /nazwa cos cos cos
https://hub.spigotmc.org/javadocs/spigot/org/bukkit/command/Command.html

oczywiscie chodzi o nazwe faktyczna nie aliasy , alias jest obok jako stringus

boolean onCommand(@NotNull
                  CommandSender sender,
                  @NotNull
                  Command command,
                  @NotNull
                  String label,
                  @NotNull
                  String[] args)

Executes the given command, returning its success.
If false is returned, then the "usage" plugin.yml entry for this command (if defined) will be sent to the player.

Parameters:
    sender - Source of the command
    command - Command which was executed
    label - Alias of the command which was used
    args - Passed command arguments
Returns:
    true if a valid command, otherwise false

więc jesli rejestrujesz JEDEN OBIEKT dla JEDNEJ komendy sprawdzanie tego jest raczej zbedne bo tylko jedna komenda jest przypisana do "executora" wykonawcy ,

double x = Double.parseDouble(getConfig().getString("RandomTP.region"));

a co tu jest dziwne :? popaczmy w dokumentacje

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/configuration/file/FileConfiguration.html

a dokladniej o tutaj
https://hub.spigotmc.org/javadocs/spigot/org/bukkit/configuration/ConfigurationSection.html#getDouble-java.lang.String-double-

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/configuration/ConfigurationSection.html#getString-java.lang.String-

a wiec bez problemow mozna z Fileconfiguration wyciagnac typy proste jak i cale obiekty , a wiec mozna zrobic getDouble("PAHTH) , a stringa moze wcale nie odszukac (nie wiem jak to jest konkretnie zrobione a nigdy tego nie sprawdzalem ) bo i po co ladowac do pamieci dwa razy to samo jako string i jako liczbe , ogolnie jest tak ze jesli wpiszesz liczbe to zostanie to wczytane jako liczba a jak chcesz stringa to dajesz go w '' .

Dzięki, że odpisałeś. Jakieś 30 min temu dowiedziałem się, że ten błąd to wina serwera, a nie pluginu. W nim był tylko 1 błąd który naprawiłem,a plugin polepszyłem, by nie zapisywało się do pamięci coś 2 razy :)
