Solved Need some help, Itemstacks and arrays, and PlayerTeleportEvents

So, working on a plugin, have 2 issues. The first is that I am saving the players inventory like this:

Code:

    @EventHandler
    public void onPlayerTeleport(PlayerTeleportEvent event){
        String oldWorld = event.getFrom().getWorld().toString();
        String newWorld = event.getTo().getWorld().toString();
       
        // if they are teleporting but not switching worlds, screw it
        if (oldWorld == newWorld) return;
       
        Player player = event.getPlayer();
        String playerName = player.getName();
        FileConfiguration config = Main.plugin.getConfig();
        ItemStack[] playerOldInv = player.getInventory().getContents();
       
        /*
         * if the config does'nt have an instance of the player's, world's, inventory, add it.
         */
       
        if (!config.contains(playerName + ".Worlds." + oldWorld + ".Inventory" + playerOldInv)){
            config.addDefault(playerName + ".Worlds." + oldWorld + ".Inventory", playerOldInv);
            Main.plugin.saveConfig();
        }

And then I set their inventory like this:

Code:

        /*
         * if the config does not have a saved inventory for the world the player is entering,
         * then create a new one and save it. Otherwise set the players inventory to the saved one
         */
       
        if (!config.contains(playerName + ".Worlds." + newWorld + ".Inventory")){
            player.getInventory().clear();
            ItemStack[] playerNewInv = player.getInventory().getContents();
            config.addDefault(playerName + ".Worlds." + newWorld + ".Inventory", playerNewInv);
            Main.plugin.saveConfig();
        } else {
            // this is where it claims the error is
            player.getInventory().setContents((ItemStack[]) config.get(playerName + ".Worlds." + newWorld + ".Inventory"));
        }

Now, it was working 2 seconds ago, however i added 2 events, PlayerQuit, and PlayerJoin.

PlayerJoin:

Code:

    @EventHandler
    public void onPlayerJoin(PlayerJoinEvent event){
       
        Player player = event.getPlayer();
        String playerWorld = player.getLocation().getWorld().toString();
       
        if (Main.plugin.getConfig().contains(player.getName() + ".Worlds." + playerWorld + "Inventory")){
            player.getInventory().setContents((ItemStack[]) Main.plugin.getConfig().get(player.getName() + ".Worlds." + playerWorld + ".Inventory"));
        } else {
            Main.plugin.getConfig().addDefault(player.getName() + ".Worlds." + playerWorld + "Inventory", player.getInventory().getContents());
            Main.plugin.saveConfig();
        }
       
    }

PlayerQuit:

Code:

    @EventHandler
    public void onPlayerLeave(PlayerQuitEvent event){
       
        Player player = event.getPlayer();
        String playerWorld = player.getLocation().getWorld().toString();
       
        if (!Main.plugin.getConfig().contains(player.getName() + ".Worlds." + playerWorld + ".Inventory")){
            Main.plugin.getConfig().addDefault(player.getName() + ".Worlds." + playerWorld + ".Inventory", player.getInventory().getContents());
            Main.plugin.saveConfig();
        } else {
            Main.plugin.getConfig().set(player.getName() + ".Worlds." + playerWorld + ".Inventory", player.getInventory().getContents());
            Main.plugin.saveConfig();
        }
       
    }

Now, when i join the game, i get this:

PHP:

Caused by: java.lang.ClassCastException: java.util.ArrayList cannot be cast to [Lorg.bukkit.inventory.ItemStack;
        at worldinventories.events.PlayerSwitchWorld.onPlayerTeleport(PlayerSwitchWorld.java:48) ~[?:?]

I have showed you where the error is, please help.

Also, I have my events registered and everything, but whenever a player joins, it claims that it is a PlayerTeleportEvent:

Code:

[07:12:59 ERROR]: Could not pass event PlayerTeleportEvent to WorldInventories v1.0
org.bukkit.event.EventException

Im getting that when i join. But it should not be a teleport event when they join.

Thanks in advance

 

Umm, where am I casting it to an Array? XD I dont even have Arrays in my imports. Thx for the tip btw
I was using it so it would set instead of add everytime, but i had no idea that worked as well

@Lordloss
I see where it is, why will that not work?

 

Btw you are comparing Strings with ==, which will not work.

 

@timtower

But why? I saved it as an itemstack[]...

Code:

        Player player = event.getPlayer();
        String playerName = player.getName();
        FileConfiguration config = Main.plugin.getConfig();
        ItemStack[] playerOldInv = player.getInventory().getContents();
     
        /*
         * if the config does'nt have an instance of the player's, world's, inventory, add it.
         */
     
        if (!config.contains(playerName + ".Worlds." + oldWorld + ".Inventory" + playerOldInv)){
            config.addDefault(playerName + ".Worlds." + oldWorld + ".Inventory", playerOldInv);
            Main.plugin.saveConfig();
        }

And here:

Code:

if (!config.contains(playerName + ".Worlds." + newWorld + ".Inventory")){
player.getInventory().clear();
ItemStack[] playerNewInv = player.getInventory().getContents();
config.addDefault(playerName + ".Worlds." + newWorld + ".Inventory", playerNewInv);
Main.plugin.saveConfig();

 

@timtower
I saved it as ItemStack[], how does it turn into list?

 

@timtower
Can i make it store the type?

 

@timtower
well, is there any other way to save the inventory to the config then add it again later?

 

@timtower
Possible, im looking at this right now:
