Anvils

Hey, so I'm trying to open an anvil and have a player be able to input text and have that text be stored in a config. I have the anvil opening and I am able to rename the item. However when I go to press the item. It cancels it like it should but instead of saving what the player typed, it saves the display name of the previous item I clicked on to get into the anvil gui. Here are some images to better explain the issue.


I had the display name print out at the bottom in chat

Made rename now say renamed

When I go to click on it, it cancels and pops up like nothing happened

And in the config,


My anvil opening class

Part of other class that opens the anvil

Code:

                    } else if(meta.getDisplayName().equals(ChatColor.GREEN + "" + ChatColor.BOLD + "Custom Prefix 1")) {
                        e.setCancelled(true);
                        Anvil1.createInv(player);

Any help is much appreciated.
Thanks,

Don't load the config each and every time you click any inventory. Check if the inventory is an anvil first, and if the anvil inventory is equal to your custom inventory, and that the player actaully clicked one of the buttons before loading the config.

The event will never be null. If it ever was, a ton of things would break (including bukkit, where the whole server would crash). There is not need for this null check.

Not only that, but you are doing it wrong. Use == for nulls, since .equals references the null object, meaning you are dereferencing a null pointer.

Null check before you get the item. If the player clicks anywhere that is not a slot, or if the slot is empty, this will return a null value.

Main thing: What does this print out? Is it equal to "Renamed"?

 

player.sendMessage(meta.getDisplayName()); prints out Custom Prefix 1, which isn't what I want. I need it to print out whatever the player inputted in the input section of the anvil.

 

@plisov
How is that possible? If the first item is "Renamed", and the result is "Renamed", then how does it get Custom Prefix 1?

[Edit] You're not checking if the inventory is the anvil. What is happening is this gets applied to all inventories on the entire server. Even if you open your inventory and click the third item in the hotbar, this will be triggered. To fix this, check if the inventory is an anvil and if the title of the anvil is equal to some custom name (choose the custom name you can the inventory)

 

I thought that was the case. I was trying to figure out how to check if the inventory type is an anvil however I couldn't find how to do it.

 

@plisov
Inventory#getType()

 

When I do if(Inventory.getType() == InventoryType.ANVIL) {

} It says that Inventory cannot be resolved to a variable

 

@plisov
That is because you have to replace "Inventory" with your inventory instance. The # signifies that the Inventory is just the class-type, and needs to be replaced with an instance.

 

So you mean I need to replace Inventory with inv since I'm doing

Code:

        Inventory inv = Bukkit.getServer().createInventory(player, InventoryType.ANVIL);

If so, it doesn't seem to work since I'm initiating it in a method and trying to call it in another method.

 

@plisov
Then you will need to create a new HashMap field. The keys will be the player's UUID, and the value will be the Inventory instance. Do this so we know which inventory the player has open.

Then, inside your other method, check if the inventory instance from the event is equal to the inventory from the hashmap. If so, you know that inv is that custom inventory.

 

This is what I have currently

}

However I don't know how to get the inventory instance from the event

 

@plisov

Code:

map.get(e.getWhoClicked().getUniqueID())

 

Code:

        if(e.getWhoClicked().getUniqueId() == map.get(e.getWhoClicked().getUniqueId()))

Is red. It's saying Incompatible operand types UUID and Inventory. How do I check if the inventory instance from the event is equal to the inventory from the hashmap? I'm certain that's not how I should be doing it.

 

@plisov
Replace the UUID (The "e.getWhoClicked().getUniqueId()" ) with the inventory instance (inv)

 

It doesn't know what inv is because it's in another method. I'm not initializing it in the event

Could I do this instead without having to do the hashmap thing?

Code:

            if(e.getInventory().getType() == InventoryType.ANVIL)

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

 

@plisov
My mistake, I meant

if(e.getInventory ==map.get(e.getWhoClicked().getUniqueID()))

 

Ah. Ok so I've done as you said but it's still not working. What it's doing is it's saving the config as I'm telling it to do however nothing is being saved.

@plisov
Isn't that how you should be getting to that inventory? What other way are you getting to that inventory?

 

@plisov
You are checking if the inventory is equal to the other inventory, but if he changes something in it, it isnt equal is it?

Looks the same as I had it

 

@plisov
It is. But its nicer to read on the website.


-Redacted- Said something wrong.

 

Ooh. That makes a lot of sense. How would I check it then to make sure it's an anvil?

 

You would still need to know if this anvil you are in is one of your unique anvils.

Which you can do the way @Zombie_Striker described.

Or you can set the anvil title to an unique id. Like Bukkit.createInventory(InventoryHolder, Size, Title)
You could generate a random uuid like UUID.randomUUID().toString()

And then add it to a List<String> on inventoryclickevent just check if List contains the title. I would recommend listen to the inventory close event too and remove the uuid from the List so it wont make memory leaks.

 

I tried setting a title to the anvil however I'm pretty sure you can't do that.

 

It's possible but not visible xD.

Bukkit.createInventory(InventoryHolder, InventoryType, Title)
You could prob just use the player uuid and not use any list.

Like

Bukkit.createInventory(InventoryHolder, InventoryType, playerUUID.tostring)

and then just checking in the event if the InventoryTitle is equal to the Players UUID. You might as well add something like Anvil: PlayerUUID.
Remeber to check still if it is a anvil.

 

@JanTuck @plisov
If you want to make the UUID invisible, add ChatColor.GRAY before the UUID. After that, you will have to use the .contains() method instead of .equals when checking the title.

 

Ah. So something like this?

If so, it doesn't seem to work.

 

@plisov

This seems odd? What slot is it printing out?
player.sendMessage(e.getSlot() + "")

@Zombie_Striker
Ik, i just thought of a alternative way to your suggestion, but it still does not seem to work.

 

I had to change that to

player.sendMessage(e.getSlot() + ""); and even then it prints out nothing. Even those messages that I set earlier don't print out unless I click on slot 0 (the one all the way to the left)
