Solved Per player custom GUI

Hello everyone! I need some help with a plugin that I am making... It is a virtual /chest plugin but I don't know how to make the /chest private because when I open it and put something in it it saves it BUT when someone else opens it it shows him my chest... For example if I opened my chest and put something in it and closed it, and another person wanted to see his chest and he wrote /chest he would see my chest because I think I programmed it that way.... I don't want it to work like that... This is my code.... I just started making an arraylist of inventories because I think it might be the first thing to start with....

Code:

public class Main extends JavaPlugin implements Listener {

    public final Logger logger = Bukkit.getServer().getLogger();
    private static Inventory inv;
    public static List<Inventory> invList = new ArrayList<Inventory>();
   
    @Override
    public void onEnable() {
        this.getServer().getPluginManager().registerEvents(this, this);

    }

    @Override
    public void onDisable() {

    }
   
    @EventHandler
    public static void onPlayerJoin(PlayerJoinEvent e){
        invList.add(0, Bukkit.getServer().createInventory(e.getPlayer(), 54, "Private Chest"));
    }

    @Override
    public boolean onCommand(CommandSender sender, Command cmd, String t,
            String[] args) {
        if (!(sender instanceof Player))
            return true;
        Player p = (Player) sender;

        if (cmd.getName().equalsIgnoreCase("chest")
                && p.hasPermission("chest.use.one")) {

            File playerSave = new File("plugins/APChests/" + p.getName() + ".invsave");
            inv = Bukkit.getServer().createInventory(p, 54, "Private Chest");
            if (new File("plugins/APChests/" + p.getName() + ".invsave")
                    .exists()) {
                inv = getInventoryFromFile(playerSave, inv, p);
                p.sendMessage("The /chest file for you exists, opening it!");
            } else {
                saveInventoryToFile(inv, new File("plugins/APChests/"),
                        p.getName());
                p.sendMessage("The /chest file for you doesn't exist, creating it!");
            }

            p.openInventory(inv);

        }
       

        return false;
    }

    public static Inventory getInventoryFromFile(File file, Inventory inv, Player p) {
        if (file == null)
            return null;
        if (!file.exists() || file.isDirectory()
                || !file.getAbsolutePath().endsWith(".invsave")) {
            saveInventoryToFile(inv, new File("plugins/APChests/"), p.getName());
            p.sendMessage("Tried opening inv but it does not exist! Creating one for you!");
        }
        ;
        try {
            FileConfiguration invConfig = YamlConfiguration
                    .loadConfiguration(file);
            Inventory inventory = null;
            String invTitle = invConfig.getString("Title", "Private Chest");
            int invSize = invConfig.getInt("Size", 54);
            int invMaxStackSize = invConfig.getInt("Max stack size", 64);
            InventoryHolder invHolder = null;
            if (invConfig.contains("Holder"))
                invHolder = Bukkit.getPlayer(invConfig.getString("Holder"));
            inventory = Bukkit.getServer().createInventory(invHolder, invSize,
                    ChatColor.translateAlternateColorCodes('&', invTitle));
            inventory.setMaxStackSize(invMaxStackSize);
            try {
                ItemStack[] invContents = new ItemStack[invSize];
                for (int i = 0; i < invSize; i++) {
                    if (invConfig.contains("Slot " + i))
                        invContents[i] = invConfig.getItemStack("Slot " + i);
                    else
                        invContents[i] = new ItemStack(Material.AIR);
                }
                inventory.setContents(invContents);
            } catch (Exception ex) {
            }
            return inventory;
        } catch (Exception ex) {
            return null;
        }
    }

    @EventHandler
    public static void onInventoryClose(InventoryCloseEvent e) {
        if (inv != null) {
            saveInventoryToFile(inv, new File("plugins/APChests/"), e.getPlayer().getName());
        }
    }

    public static boolean saveInventoryToFile(Inventory inventory, File path,
            String fileName) {
        if (inventory == null || path == null || fileName == null)
            return false;
        try {
            File invFile = new File(path, fileName + ".invsave");
            if (invFile.exists())
                invFile.delete();
            FileConfiguration invConfig = YamlConfiguration
                    .loadConfiguration(invFile);

            invConfig.set("Title", inventory.getTitle());
            invConfig.set("Size", inventory.getSize());
            invConfig.set("Max stack size", inventory.getMaxStackSize());
            if (inventory.getHolder() instanceof Player)
                invConfig.set("Holder",
                        ((Player) inventory.getHolder()).getName());

            ItemStack[] invContents = inventory.getContents();
            for (int i = 0; i < invContents.length; i++) {
                ItemStack itemInInv = invContents[i];
                if (itemInInv != null)
                    if (itemInInv.getType() != Material.AIR)
                        invConfig.set("Slot " + i, itemInInv);
            }

            invConfig.save(invFile);
            return true;
        } catch (Exception ex) {
            return false;
        }
    }

}

So yeah... Any help would be great! Thank you!

 

Try a HashMap using UUID and Inventory

 

@BrickBoy55 Hey, someone told me that once but I don't know how to really use HashMaps since I never needed them before.... Can you please explain it to me how I could implement it into my own code? Thanks! EDIT: I tried implementing them into my code and this is what I have come up with:

Code:

public class Main extends JavaPlugin implements Listener {

    public final Logger logger = Bukkit.getServer().getLogger();
    private static Inventory inv;
    public static HashMap<UUID, Inventory> invList = new HashMap<UUID,Inventory>();
    @Override
    public void onEnable() {
        this.getServer().getPluginManager().registerEvents(this, this);

    }

    @Override
    public void onDisable() {

    }
   
    @EventHandler
    public static void onPlayerJoin(PlayerJoinEvent e){
        invList.put(e.getPlayer().getUniqueId(), Bukkit.getServer().createInventory(e.getPlayer(), 54, "Private Chest"));
    }

    @Override
    public boolean onCommand(CommandSender sender, Command cmd, String t,
            String[] args) {
        if (!(sender instanceof Player))
            return true;
        Player p = (Player) sender;

        if (cmd.getName().equalsIgnoreCase("chest")
                && p.hasPermission("chest.use.one")) {

            File playerSave = new File("plugins/APChests/" + p.getName() + ".invsave");
            inv = Bukkit.getServer().createInventory(p, 54, "Private Chest");
            if (new File("plugins/APChests/" + p.getName() + ".invsave")
                    .exists()) {
                inv = getInventoryFromFile(playerSave, invList.get(p.getUniqueId()), p);
                p.sendMessage("The /chest file for you exists, opening it!");
            } else {
                saveInventoryToFile(invList.get(p.getUniqueId()), new File("plugins/APChests/"),
                        p.getName());
                p.sendMessage("The /chest file for you doesn't exist, creating it!");
            }

            p.openInventory(invList.get(p.getUniqueId()));

        }
       

        return false;
    }

    public static Inventory getInventoryFromFile(File file, Inventory inv, Player p) {
        if (file == null)
            return null;
        if (!file.exists() || file.isDirectory()
                || !file.getAbsolutePath().endsWith(".invsave")) {
            saveInventoryToFile(inv, new File("plugins/APChests/"), p.getName());
            p.sendMessage("Tried opening inv but it does not exist! Creating one for you!");
        }
        ;
        try {
            FileConfiguration invConfig = YamlConfiguration
                    .loadConfiguration(file);
            Inventory inventory = null;
            String invTitle = invConfig.getString("Title", "Private Chest");

}

I am about to test it out hopefully it will work

@BrickBoy55 Hey, just wanted to say that it works now thanks

EDIT by Moderator: merged posts, please use the edit button instead of double posting.

 

No problem! I used to not know how to use HashMaps also and got yelled at for not knowing java.

 

@mateo226 I see you learned from my post from the last thread hehe xD
