Util AnvilGUI - Use the Anvil GUI to retrieve Strings!

Hey guys,

I was playing around with various NMS-related things and long story short, I ended up coming up with this. It basically allows you to get user-inputted text by using the anvil GUI. Here is the class:

View the gist here: https://gist.github.com/chasechocolate/a9eff3d0cd577e6c098ae59286da3961

NOTE: This requires the use of CraftBukkit, but I may come up with a reflection version later.

If you guys come up with any cool usage ideas for this, then post them here! I'm interested in what you come up with. Dippoakabob was talking about storing passwords, but I'm sure there are many other usages!

Enjoy!

You have done it again. You have amazed everyone with your creation. No wonder you are a BukkitDev staff.

 

Such amaze!
Thanks for your awesome work Chase!

 

Nice idea, could this also be done with the command block GUI then?

 

There is already a command block GUI thread out

Thanks, i just had a quick look with search something like 'command block GUI' but didn't find that

 

Looks nice

 

I don't understand coding but I love the colors!

 

This is very cool! I love how it's self-contained (versus InputLib).

I've been wanting a text-entry GUI for a while, here are a few ideas I had (since you asked!)

- Send message to targeted player
- Edit target command block (.. I'd love to be able to do this without creative mode ..)
- I dunno... other stuff? I just love the idea of players not having to use server commands for gamey things...

The 2nd one I may try out soon. Admittedly, I'd much rather pop up a command block GUI for that (er, obviously?) but I don't want protocollib so I think I'll try your anvilgui first

Thanks for another great nugget of code and wisdom, chasechocolate!

How can I get what the player types in the typing slot? Or is that what your example is doing because I don't really understand what is happening in it.

 

PieMan456 I suppose you could just pull the ItemMeta from the item in the result slot, but the way I made it calls that method when the player clicks on the item in the result slot.

 

PieMan456 Its what he is doing, i think i have an example somewhere, let me find it.

//Edit: Here, found it:

Code:java

renamePet(event.getPlayer(), anvilClickEvent.getName());

Pretty easy to get the String inputed as long as he clicks the output item.

 

chasechocolate I have a problem, i use everything like you did in the resource, here's my code:

Code:java

public void openAnvil(final Player p, final int amount) {
AnvilGUI gui = new AnvilGUI(p, new AnvilGUI.AnvilClickEventHandler() {
@Override
public void onAnvilClick(final AnvilGUI.AnvilClickEvent event) {
if (event.getSlot() == AnvilGUI.AnvilSlot.OUTPUT) {
event.setWillClose(true);
event.setWillDestroy(true);
ItemStack skull = new ItemStack(Material.SKULL_ITEM,
amount, (short) 3);
SkullMeta im = (SkullMeta) skull.getItemMeta();
im.setOwner(event.getName());
skull.setItemMeta(im);
p.getInventory().addItem(skull);
takeHeadCoins(p, amount);
p.sendMessage("§2[JacintoCabeças] §6Compraste §r"
+ amount
+ " §6cabeças de §b"
+ event.getName()
+ "§6. §c(Isto não pode ser devolvido)");
}else{
event.setWillClose(true);
event.setWillDestroy(true);
}
}
});
ItemStack tag = new ItemStack(Material.NAME_TAG);
ItemMeta im = tag.getItemMeta();
im.setDisplayName("Escolhe o nome");
tag.setItemMeta(im);
gui.setSlot(AnvilGUI.AnvilSlot.INPUT_LEFT, tag);
 
gui.open();
}

But when i click the name tag to close the inventory this bug prints out:

Code:

[18:34:10] [Server thread/INFO]: [WorldEdit] Using inbuilt NmsBlock for this version.

The line 161 of AnvilGUI is:

Code:java

@EventHandler
public void onInventoryClose(InventoryCloseEvent event) {
if (event.getPlayer() instanceof Player) {
Player player = (Player) event.getPlayer();
Inventory inv = event.getInventory();
 
if (inv.equals(AnvilGUI.this.inv)) {
//this one is the line 161(inv.clear();)
inv.clear();
destroy();
}
}
}

Could someone help me fixing this? chasechocolate

 

Just tried this little-lib and I get same error Pik0 has, but it looks like we're not able to fix it?. Wondering if I can just put it into try-catch to remove this awful stacktrace. Won't there be any side-effects?
#Edit
Another problem is when I try to set output by myself - I get same exception. It looks like Anvil inventory has only 2 slots, like if there is no output for server... F**k logic!

 

Chlorek I just put a catch in the method and it worked

 

chasechocolate First off, this looks amazing! Second, does it work for 1.7.9 R.02? And lastly, if it does, how exactly would I open the anvil for someone and get the text inputted? Sorry, but I'm still rather nooby with Java, and I don't see an open method to open the anvil for a player, other than the open() one, which doesn't take a player. How would I go about this?

1. Yes, it should still work, however you may need to fix the NMS imports to take your version of CraftBukkit.
2. In the constructor of the class, it takes a Player parameter, and when you call open() it will open the GUI for the player that was passed in the constructor.

 

chasechocolate Ah, didn't see that. Thanks so much! Just one more thing: where am I supposed to get the player from? Wow, I'm stupid. Please ignore this whole post.

 

chasechocolate I've done exactly what you've said to do. Everything works good but how do you open the gui?

 

Another awesome work from chasechocolate !

 

This is really cool! Nice job @chasechocolate

 

chasechocolate, it doesn't seem to be working for me... It'll open for a split second and immediately close again ;/

EDIT: Hmm... It seems that it only does this when I open with my click gui...

EDIT #2: Sigh, I was closing the players current inventory after they opened the inventory instead of before xD

 

So has anyone got around to creating a version of this class using Reflections? I would but I have no clue how to use reflection when i need to extend something, or even if reflection can do that...

 

Nothing works

 

OK this whole post of me was just stupid, I have forgotten, what I was doing is already possible by getting the name of the output item since it is the same as the text written in the anvil...

 

Is there a version for 1.8 available?

 

Seems to be broken for 1.8, is there a fix?

 

There is any way to get more characters? When i click on item, the string is cut by 30 characters.

 

Using this on 1.8.3. Got some errors.
How would i fix undefined errors?
