Gui Help.

I would really like help in knowing how to make a GUI. This has always been of interest to me but I have no clue how to do it. Any help would be appreciated. Thanks

 

Do you mean an Inventory GUI?

 

bangman
Yeah. Where it looks sort of like a chest or inventory but it shows custom items and you cant edit the placement of them.

 

Ah, well the basics are:
You can grab an instance of Inventory with Bukkit.createInventory(null, <InventorySlots>, "Inventory Title");
The amount of slots must a be a multiple of 9, so can be: 9, 18, 27 ect.....

To edit what is in the inventory you can simply setContents(); of the inventory with an ItemStack array and modify the appearance of these items by editing their ItemMeta.

To finish, you can openInventory(your inventory instance) on any player to display your fancy GUI!

Edit: This tutorial also looks fairly helpful

Also, you should create an ArrayList with players that have the inventory open and listen for InventoryClickEvent to catch when they click on something and cancel the event

Um? Why an ArrayList? On inventory click event check what inventory they have open.

He means that when they open the gui it adds them to an array list so they cant edit the gui. Then when they close it they are removed from the array list.

 

Code:

public void onInvClick(InventoryClickEvent event) {
Player bukkitPlayer = (Player) event.getWhoClicked();
 
if (bukkitPlayer.getInventory().getName().equals(myInv.getName()) {
event.setCancelled(true);
}
}

Like I said, check what inventory is open and if it's one you don't want players to edit things in gui, cancel it.

 

Konkz
Oh. I see what you are saying. Thanks . I will try that

Konkz and bangman
How would I display a certain players head in one of the inventory slots. I know id have to edit like the itemmeta or something but idk how. Thanks

If nobody helps yiu by tomorrow then I will as I'm too lazy and tired to write it up on my phone.

 

Konkz
Ok. Thanks a lot

 

Here

PHP:

            ItemStack is = new ItemStack(Material.SKULL_ITEM, 1, (short) 3);
            SkullMeta im = (SkullMeta) is.getItemMeta();
            im.setOwner(bukkitPlayer.getName());
            im.setDisplayName(bukkitPlayer.getName());
            is.setItemMeta(im);

Thanks a ton

 

Here's some code from my project :

Inventory Class

Code:

public static Inventory getCompassInv() {
Inventory inv = Bukkit.createInventory(null, 9, "Game Menu - Pick a game!");
 
{
ItemStack item = new ItemStack(Material.BOW, 1);
ItemMeta meta = item.getItemMeta();
meta.setDisplayName("§6Survival Games");
List<String> lore = new ArrayList<String>();
lore.add("§7Hunger games, but in minecraft");
meta.setLore(lore);
item.setItemMeta(meta);
inv.setItem(1, item);
}
 
return inv;
}

ClickedItem Class :

Code:

@EventHandler
public void onClick(InventoryClickEvent event)
{
if(event.getInventory().getTitle().equalsIgnoreCase("Game Menu - Pick a game!"))
{
if(event.getCurrentItem() != null && event.getCurrentItem().getType() != null)
{
event.setCancelled(true);
Player p = (Player) event.getWhoClicked();
if(event.getCurrentItem().hasItemMeta() && event.getCurrentItem().getItemMeta().hasDisplayName())
{
 
event.setCancelled(true);
 
ItemStack clicked = event.getCurrentItem();
if (clicked!=null){
if (event.getCurrentItem().getItemMeta().getDisplayName().contains("§6Survival Games")){
p.sendMessage("Survival Games is closed.");
}
}
}
}
}
}

 

So I've coded a gui, yet it does not seem to work. Can anyone help me with finding the problem.
(Note: I'm not 100% sure that the problem is where I create the inventory. It could be somewhere else)
Main Class:

Code:java

package me.zakarls.GUI;
 
import java.util.logging.Logger;
 
 
import org.bukkit.command.Command;
import org.bukkit.command.CommandSender;
import org.bukkit.entity.Player;
import org.bukkit.plugin.PluginDescriptionFile;
import org.bukkit.plugin.PluginManager;
import org.bukkit.plugin.java.JavaPlugin;
 
public class GUI extends JavaPlugin {
    public final Logger logger = Logger.getLogger("Minecraft");
 
    @Override
    public void onDisable() {
        PluginDescriptionFile pdfFile = this.getDescription();
        this.logger.info(pdfFile.getName() + " Has Been Disabled!");
    }
 
    @Override
    public void onEnable() {
        PluginDescriptionFile pdfFile = this.getDescription();
        this.logger.info(pdfFile.getName() + " Version " + pdfFile.getVersion()
                + " Has Been Enabled!");
        PluginManager pm = getServer().getPluginManager();
        pm.registerEvents(this.ml, this);
    }
    public final MyListener ml = new MyListener(this);
 
 
    public boolean onCommand(CommandSender sender, Command cmd,
            String commandLabel, String[] args) {
        Player player = (Player) sender;
        if(commandLabel.equalsIgnoreCase("staff")){
            ml.show(player);
        }
 
 
 
 
        return false;
    }
}

        ItemStack is = new ItemStack(material, 1);
        ItemMeta im = i.getItemMeta();

Thanks for any help on this issue.
