    Is there any way to save and retrieve a player's inventory? I have googled this extensively and nothing is working. I have saved the inventory to config like this:

    Code:
            String oldWorld = event.getFrom().getWorld().getName();
        String newWorld = event.getTo().getWorld().getName();
       
        // If player is telporting within the world, forget it
        if (oldWorld == newWorld) return;
       
        Player player = event.getPlayer();
        String playerName = player.getName();
        FileConfiguration config = Main.plugin.getConfig();
        ItemStack[] playerInvOld = player.getInventory().getContents();
       
        // save the old inventory of the player
            config.addDefault(playerName + ".Worlds." + oldWorld + ".Inventory", playerInvOld);
            Main.plugin.saveConfig();
           
        // if player dosent have a saved inventory for the old world, make a new one.
        if (!config.contains(playerName + ".Worlds." + newWorld + ".Inventory")){
            player.getInventory().clear();
            config.addDefault(playerName + ".Worlds." + newWorld + ".Inventory", playerInvOld);
            Main.plugin.saveConfig();
    Then I have tried to set the inventory in a few ways:

    Code:
                ArrayList<?> playerInvNewList = (ArrayList<?>) Main.plugin.getConfig().get(playerName + ".Worlds." + newWorld + ".Inventory");
            ItemStack air = new ItemStack(Material.AIR, 1);
            player.getInventory().clear();
            for (Object item : playerInvNewList){
                if (item == null){
                    player.getInventory().addItem(air);
                }
                else {
                player.getInventory().addItem((ItemStack) item);
                }
    And i have tried just setting it to the saved inventory. I ALWAYS get the error of not being able to cast to ItemStack from ArrayList. Any ideas?

    I would suggest you to use <ItemStack> instead of <?> so you dont have to iterate over a list of objects. At which line it tells you youre casting from ArrayList? Btw, this doesnt seem to be your full code of loading inventories.

    Its most of it, i have others that do the same thing when a player joins, btw i tried that as well and the same thing showed up. Also, the error is here:
    Code:
                    else {
                player.getInventory().addItem((ItemStack) item);
                }

    I would check if item is instanceof ArrayList. If so, you have to figure out why. Please show us your config.

    The worlds are the same because it still saved the inventories, it just didnt switch them.
    Working on it instance of thing.
