Cannot get this thing to work!

I need to serialize a player's inventory. So I want to save an inventory, and load it back when called upon to do so. My code:

Code:java

if (cmd.getName().equalsIgnoreCase("duty")) {
            Player player = (Player) sender;
            if (!sender.hasPermission("fcGuardPlugin.on")) {
                sender.sendMessage("You do not have permission");
            }
            if (sender.hasPermission("fcGuardPlugin.on")) {
                if (args.length == 1 && args[0].equalsIgnoreCase("on")) {
                    if (sender instanceof Player) {
                        File fcGuardPlugin = new File("plugins"
                                + File.separator + "fcGuardPlugin"
                                + File.separator + "Data");
                        File GuardInv = new File(fcGuardPlugin,
                                player.getName() + ".yml");
                        YamlConfiguration Guardconfig = YamlConfiguration
                                .loadConfiguration(GuardInv);
                        PlayerInventory inv = player.getInventory();
                        String invAsString = InventoryToString(inv);
 
                        if (!GuardInv.exists()) {
                            try {
                                GuardInv.createNewFile();
                            } catch (IOException e) {
                                e.printStackTrace();

                                            .replace("&", "§"));
 
                            Guardconfig.set(player.getName() + " Inventory",
                                    invAsString);

I am completely out of ideas and just frustrated; been dealing with this issue for about a week now.

 

HeadGam3z

I am gonna go out on a limb and say that invInfo is incorrectly assigned. What should it be?

 

mrkirby153
What do you mean what should it be?

 

HeadGam3z

A number. Not a string. Print out the value of invInfo and chances are, it is not what you expect.

 

mrkirby153
I tried to print it out by using System.out.print(invInfo); and nothing happened when it got called - other than the error I've been getting.

 

HeadGam3z You've made like 10 posts, with the exact same problem. When you are trying to turn the String into an Inventory, you just keep passing in "<PlayerName> Inventory", the method expects that you pass in a String that is a serialized inventory, which "<PlayerName> Inventory" clearly isn't. You pass in the invalid String, it tries to turn that into an Inventory, and errors are thrown because its not an Inventory that was serialized.
Solution: Pass in the serialized inventory

 

xTigerRebornx
The serialized inventory is right after "<PlayerName> Inventory" (i.e HeadGam3z Inventory: 32#432;324234yadayda) The problem for me is, I don't know how to pass it to the serialized inventory, because I do not know how to get to it.

 

Bump.
