Bukkit如何更改配置文件中的int，然后能够再次更改它而无需重新加载(自定义配置文件类.) [英] Bukkit How to change an int in the config file then be able to change it again without reloading (Custom config file class.))
问题描述
好的，所以我正在为OP-Prison服务器创建自定义功能，我需要做的一件事情就是从players.yml文件中获取一个整数，检查它是否> =一个，如果是删除一个，保存它，然后如果它仍然高于1，则他们可以重复该操作，直到它为0. 问题在于我必须重新启动服务器才能更改文件，即使我这样做，它一次也只会下降一个整数，而不必再次重新加载.
Okay so I am making a custom feature for my OP-Prison server, one of the things that I need to do is get an integer from the players.yml file, check if it is >= one, if it is take away one, save it and then if it is still above one then they can repeat the action untill it's 0. The issue comes with the fact that I have to restart the server for the file to change, and even when I do, it will only go down by one integer at a time, before having to reload it again.
GUI创建代码:
Main main = Main.getPlugin(Main.class);
@SuppressWarnings("unused")
private FileControl fc;
@SuppressWarnings("unused")
private FileControl playerfc;
public static String inventoryname = Utils.chat(Main.pl.getFileControl().getConfig().getString("Backpacks.White.InventoryName"));
public List<Player> WhiteOpened = new ArrayList<>();
public static Inventory whiteBackpack(Player player) {
Inventory whiteBackpack = Bukkit.createInventory(null, 27, (inventoryname));
UUID uuid = player.getUniqueId();
whiteBackpack.setItem(10,
new ItemCreator(Material.INK_SACK).setData(8)
.setDisplayname(Utils.chat("&fCommon Packages &8» &f&l" + Main.pl.getPlayerFile().getConfig().getInt("Users." + uuid + ".Packages.Common")))
.getItem());
return whiteBackpack;
}
单击Commonpackage时更新config +项目的代码:
Code for updating the config + item when the Commonpackage is clicked:
@EventHandler
public void whiteBackpackInteract(InventoryClickEvent event) {
Player player = (Player) event.getWhoClicked();
UUID uuid = player.getUniqueId();
ItemStack clicked = event.getCurrentItem();
String title = event.getInventory().getName();
if (title.equals(inventoryname)) {
// Making it so that the item cannot be moved
event.setCancelled(true);
if (clicked != null) {
if (event.getSlot() == 10) {
// Getting the user's common packages section in the config and checking if it is greater than or equal to 1.
if (Main.pl.getPlayerFile().getConfig().getInt("Users." + uuid + ".Packages.Common") >= 1) {
// Saving the user's common package section to 'currentCommon'
Integer currentCommon = Main.pl.getPlayerFile().getConfig().getInt("Users." + uuid + ".Packages.Common");
// Taking away one from 'currentCommon' and saving it to 'newCommon'
Integer newCommon = currentCommon - 1;
// Getting the 'players.yml' file
File file = new File(main.getDataFolder(), "players.yml");
FileConfiguration config = YamlConfiguration.loadConfiguration(file);
// Checking if the current common keys is greater than or equal to 1
if (currentCommon >= 1) {
try {
//Now, Here's where the error lies.
//Gets the player's common package count and sets it to the 'newCommon' count
config.set("Users." + uuid + ".Packages.Common", newCommon);
//Saves the players.yml file
config.save(file);
} catch (IOException e) {
e.printStackTrace();
}
// Updates the inventory they're currently in (Atleast it's meant to...)
player.updateInventory();
// Sends them a message (This is just for testing purposes, making sure it's working.)
player.sendMessage(Utils.chat("&8(&9Vexil&8) &fCommon Package"));
}
}
}
}
}
}
如果您需要任何其他代码，请问我会很乐意为您提供.
If there is any other code that you need, just ask I'll happily provide it for you.
推荐答案
您正在使用Main.getPlugin();
You are using Main.getPlugin();
现在，虽然这看起来似乎不是一件坏事，但是您得到了一个未分配的变量，我不知道它是如何工作的，但是您正在将Main分配给Main.实际获得主类有两种正确的方法.
Now while that doesn't seem like such a bad thing, your getting an unassigned variable, I have no idea how it is working but you're assigning Main to Main. There are 2 proper ways to actually get the main class.
第一种也是通常最好的方法是使用依赖项注入.
The first, and generally best way, is to use dependency injection.
所以基本上，
public class Main extends JavaPlugin {
@Override
public void onEnable() {
BackpackListener listener new Backpacklistener(this);
getServer().getPluginManager().registerEvents(listener, this);
}
}
public class BackpackListener implements Listener {
private Main instance;
private BackpackUtil util;
public BackpackListener(Main instance) {
this.instance = instance;
util = new BackpackUtil();
}
@EventHandler
public void onClick(InventoryClickEvent event) {
//code
util.whiteBackpack(instance);
}
public class BackpackUtil {
public Inventory whiteBackpack(Main instance) {
FileConfiguration config = instance.getConfig();
//Do things
instance.saveConfig();
}
}
您可以通过另一种方法来达到最佳效果，并对此表示反对，但仍然是一个更简单的选择.
The next way you can do it is less optimal, and frowned upon, but still an easier option.
public class Main() {
public static Main instance;
@Override
public void onEnable() {
instance = this;
}
}
public class ConfigHelper() {
Main instance = Main.instance;
FileConfiguration config = instance.getConfig();
//Do things
instance.saveConfig();
}
摆脱使用第二种方法(称为单例)的习惯是一件好事，因为通常主类会更改，或者具有多个实例，等等.但是在Spigot中，只能有一个主实例和一个线程.
It's good to get out of the habit of using the second method (It's called a singleton), because normally the main class will change, or have multiple instances, etc... but with Spigot there can only be one main instance and one thread.
