Inventory

Does anyone have a tutorial/code to save a player's inventory, and then load it again? I found something like this, but it was very out of date and didn't work. I need it for a plugin of mine, like: I want to be able to use a command and it saves the sender's inventory, then clears it. Upon using a different command, it loads the previously saved inventory back to the sender. I know what to do, it's just how to save then load the inventory again that I do not know how to do.

Any help would be great!

Perhaps put the inventory into a HashMap, then save/load the HashMap?

See:

(Saving/Loading a HashMap)

I looked at that earlier, and I could not get it to load back the saved inventory for the life of me.

I actually did try this, and it went well. But, once when the server restarted, it went bye-bye. So I do not think a hashmap would be useful here.

using the class from the link i sent you do this:

Code:java

 
Inventory i = StringToInventory(string);
player.getInventory().setContents(i.getContents());

I added what you said, and got the following error:

The off command:

Code:java

                if (args.length == 1 && args[0].equalsIgnoreCase("off")) {
                    Msg("1"); // in-game debug (did show)
                    File fcGuardPlugin = new File("plugins" + File.separator
                            + "fcGuardPlugin" + File.separator + "Data");
                    File GuardInv = new File(fcGuardPlugin, player.getName()
                            + ".yml");
                    YamlConfiguration Guardconfig = YamlConfiguration
                            .loadConfiguration(GuardInv);
                    if (Guardconfig.getBoolean(player.getName() + " OnGuard")) {
                        Msg(getConfig().getString("Duty_Off_Message")
                                .replace("%p", player.getName())
                                .replace("&", "§"));
                        player.getInventory().clear();
                        player.getInventory().setArmorContents(null);
                        getLogger().info("Message1"); // console debug (did show)
                        Inventory i = StringToInventory(player.getName()
                                + " Inventory");
                        player.getInventory().setContents(i.getContents());
                        getLogger().info("Message2"); // console debug (didn't show)
                        Guardconfig.set(player.getName() + " OnGuard",
                                Boolean.valueOf(false));
                        getLogger().info("Message3"); // console debug (didn't show)
                        try {
                            Guardconfig.save(GuardInv);
                        } catch (IOException e) {
                            e.printStackTrace();
                        }
                        return true;
                    }
 
                }

Now, when I use the on command, it saves the sender's inventory into a file, and gives them a kit. It saved as "HeadGam3z Inventory: 36;"
When I tried to use the off command to get my inventory back, I got the error above.

Anyone?

 

well if you want to save its contents only you may want to look to my post here

I need to save everything, really. :/

 

HeadGam3z
What I would do is probably the same method as what ive sent earlier but then seperated like:

con.set("armor", p.getInventory().getArmorContents());
con.set("items", p.getInventory().getContents());

ive made in my own plugin this to switch game modes:
https://github.com/xEssentials/xEss...ntials/instances/xEssentialsPlayer.java#L2302

 

xize
Good idea. Items will still be saved even on restart?

 

HeadGam3z
yep this saves it as a yaml file, I recommend to save it like player_creative.yml or player_survival.yml or per world base?

 

xize
Hmm, I looked at your post with the link, and I don't see how that would work now. Considering I just looked at something with 2000+ lines... lol

loading:

Code:

    /**
    * @author xize
    * @param loads the inventory of the player
    */
    @SuppressWarnings("unchecked")
    public void loadInventory() {
        ItemStack[] contents = ((List<ItemStack>)con.get("orginalinv.items")).toArray(new ItemStack[0]);
        ItemStack[] armor = ((List<ItemStack>)con.get("orginalinv.armor")).toArray(new ItemStack[0]);
        player.getInventory().setContents(contents);
        player.getInventory().setArmorContents(armor);
        con.set("orginalinv", null);
        try {
            con.save(f);
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        update();
    }

saving:

Code:

    /**
    * @author xize
    * @param saves the inventory of the player
    */
    public void saveInventory() {
        con.set("orginalinv.items", player.getInventory().getContents());
        con.set("orginalinv.armor", player.getInventory().getArmorContents());
        try {
            con.save(f);
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        update();
    }

this will save and load the armor and normal contents of a inventory, however if you want a title you can save it as a seperated String, this also saves lores and ItemMeta without the chance its removed

-edit-

note that the update(); method is just a con.load(f); (a loading file mechanism).
