[Tutorial] Create a Inventory Menu!

Heres a small snipit of the code im messing with. Is there a way to make it when the player clicks and item and has it following the cursor, to set that to null, so essentially they can't move the items? The only solution so far is to include the player.closeInventory() but i was hoping for a way to keep it open so players can check out multiple stats. Also quick side note great tutorial.

Code:

                    else if(clicked.getType() ==Material.BOW)
                    {
                            event.setResult(Result.DENY);
                            event.setCancelled(true);
                            player.setItemOnCursor(null);
                            player.updateInventory();
                            //player.closeInventory();
                            int playerarchery;
                            PlayerData pd = new PlayerData(player.getName());
                            playerarchery = pd.getData().getInt("Archery");
                            player.sendMessage("Your archery is: " + playerarchery);
           
                    }    

 

valon750: Take a look at Ultimate_n00b's class.. If you use it you can set multiple lines of lore using the addButton function.

Code:java

public IconMenu addButton(Row row, int position, ItemStack item, String name, String... lore)

Lone

 

Mine only works when I do this:

Code:java

 public static org.bukkit.inventory.Inventory myInventory = Bukkit.createInventory(null, 9, "Inventory");

Even if i do import it, it says its an unused import

EDIT: NEVERMIND I know what I did wrong, the name of my class is Inventory oops

 

What would I have to do if I wanted a skeleton spawn egg instead of a block in the inventory?

 

JPG2000 in your first code line you have Bxukkit xD

 

How to check if the clicked item is custom?

Code:java

 if (event.getInventory() != shopinventory){
player.sendMessage("This is not the shop you're looking for");
return;
}
if (event.getCurrentItem() == getAbilities(ShopItems.Abilities)){
player.sendMessage("Works");
event.setCancelled(true);
}

Code:java

 public enum ShopItems {
Abilities;
}
 
@SuppressWarnings("incomplete-switch")
public ItemStack getAbilities(ShopItems item) {
Potion potion = new Potion (PotionType.REGEN, 1);
ItemStack potionstack = potion.toItemStack(1);
ItemMeta meta = potionstack.getItemMeta();
ArrayList<String> lore;
switch (item) {
case Abilities:
meta.setDisplayName(ChatColor.ITALIC + "Abilities");
lore = new ArrayList<String>();
lore.add(ChatColor.BLUE + "Find your abilities here!");
meta.setLore(lore);
potionstack.setItemMeta(meta);
}
return potionstack;
}

Doesn't work for me though.

 

Uuhm i need help :S i making a wand plugin but i wanna set a magic wand on a air material in slot 9 can someone help me? please

 

I would really like to use this, everything works except for the keeping it in the inventory part :3

EDIT: Nvm I figured it out a different way

 

OMG Thx man I love your "Tutorials" you helped me a lot <3
#No Homo :3

Awsome Tutorial man :3 but I have a questions how do I make that there Heads from Players in the Menu?

 

Make a normal player head like this tutorial linked below, and add it to the menu as an itemstack: https://bukkit.org/threads/trying-to-make-a-skull-head-the-players-head.180623/

 

Hey how do i set the Slot for the Item Stack / Meta it doesnt show the way I do it

Code:

   public static void createDisplay(Material material, Inventory inv, int Slot, String name, String lore) {
           ItemStack Bedwars = new ItemStack(Material.BED);
           ItemMeta BedwarsMeta = Bedwars.getItemMeta();
           BedwarsMeta.setDisplayName(ChatColor.BLUE + "Bedwars");
           ArrayList<String> Lore = new ArrayList<String>();
           Lore.add( ChatColor.GREEN + "Teleportiert dich zu" + ChatColor.BLUE + "Bedwars" + ChatColor.GREEN + "!");
           Bedwars.setItemMeta(BedwarsMeta);
           inv.setItem(11, Bedwars);
           
           }
      
      
       

 

it says "The method setItem(int, org.bukkit.inventory.ItemStack) in the type Inventory is not applicable for the arguments (int, net.minecraft.server.v1_8_R3.ItemStack)" What to do about that?

 

@timtower Yay! It works! Thanks so much!

it says the "The constructor ItemStack(Material, int) is undefined" how do I define it? there's no import option.

EDIT by Timtower: merged posts
???????

And also, how do I name the items inside the inventory?

<Edited by bwfcwalshy: Merged posts, please use the edit button rather than double posting.>

 

How can I add items to the GUI shop with commands?
E.g. /shop additem
Then, it will get the item in my hand and save it to the config file so when I type /shop, it shows all the item from the config file. Can someone help me?

 

Thanks!

Bxukkit should be Bukkit

 

Nice tutorial, but if I click on a empty slot (so in my own inventory or on a empty slot in the GUI) it gives an NullPointerException in my console,

how can I fix this?

First, why are you replying to a tread that is over a year old? That's necro-posting, and not needed.

Secondly, check if it's null when getting it? Do you know Java?

 

first, this is the only good tutorial I can find on the web, so i did asked it here,

and yes i do know java, and I did checked that with this line:
if (e.getCurrentItem().getItemMeta() == null) return;

Code:

if (e.getCurrentItem().getItemMeta() == null) return;

but that did not worked

 

Returning it will do nothing. Just check if the item is not null before executing your code.

 

Can you please give an example of this in use? i cant seem to get it to work. Also how would you set the amount of the material?

 

What if I want to have the same items but with different names??

 

And, how to save the inventory? Because i have another class, in this, i add items for the inventory, but, when i reload the server, all items remove.

 

@FiesteroCraft When you reload the server, the plugin instance is literally tossed aside by Bukkit/Spigot and a new instance is created, so you need to use either a database or the configuration files.

Creating a simple configuration file for inventory persistence shouldn't be too hard to do on your own.

 

Hey guy, author of the theme, i'm really grateful to you for this guide, you really helped me. THANK YOU A LOT!

 

how to close the inventory for everyone who is using the menu?
