Solved Needing help with creating a GUI

Hi, I am needing help with my plugin, This what I want to do,

I am trying to create a GUI that is like HYPIXEL Vanity Shop,
It has a all pets in 1 GUI then at the bottom it says Back and then right next to that it
says Page 2 then when you click on Page 2 it opens the 2ND GUI but at the bottom it says Page 1 and then right next to that it says Page 3 I am wanting to create something like that but make it like so I can allow it in to my API so others can use to create there own GUI, How would I go about doing this,

And How would I create a GUI that allowes me to create something like on HYPIXEL GameMenu it has Animation I got Anamtions but I don't know how to make it so it updates the Lore with the next Animation! I know this is a lot to ask but I am still learning about JAVA I am good at coding small plugins but This one is my very first huge plugin that is made for Lobbys or Hubs!

If you like to help me with this project just PM

 

Does anyone else feel like they are listening to a child on high amounts of caffiene/sugar when they read that? Lol.
xxmobkiller, this is a fairly complicated system that is not for the unexperienced with java or the minecraft api. I am actually doing this in a later version of a plugin I am developing right now. In my circumstance, I have to deal with multiple windows based on the amount of entries of a user in the config. It gets complicated fast. Also, there are several libs and resources that do this already (which I do not plan on using, I like the challenge)

 

Tecno_Wizard Couldn't have said it better myself.
xxmobkiller There are plenty of tutorials on how to make GUIs and as for pets you will have to look into NMS and packets

 

I got some help from a friend for animation Lores But This what I got for more then 1 page GUI

It works but if more then 1 player opens it and if the other player clicks on something it want give it to that player but he must have to click it 2 times for it to give him the item,

The GadgetsMenuActions is what calls GadgetsGUI and then LobbyEssentials is what calls GadgetsMenuActions

Code:java

 
 
GadgetGUI gadgets = new GadgetGUI(StringUtils.join(Arrays.asList("Gadgets"), ""), getMenuItems(), new GadgetsMenuAction());
 

Code:java

I use that to call when I want to open a menu.

Code:java

Code:java

import com.excitedgamerdud.gui.Gadgets;

public class GadgetsMenuAction implements GadgetGUI.MenuAction{
 
public void onInventoryClick(Player player, ItemStack item, int slot, GadgetGUI menu, GadgetGUI.MenuPage page) {
if ((item != null) && (item.getType() != Material.AIR)) {
if (item.getType() == Material.ARROW) {
menu.open(player, slot == 41 ? page.getId() + 1 : page.getId() - 1);
} else {
if (item.getType() == Material.GLASS) {
player.getInventory().setItem(3, null);
player.playSound(player.getLocation(), Sound.NOTE_PLING, 2.0F, 4.0F);
} else {

xxmobkiller, I have to ask, is English your first language, because I am finding your writing to be very hard to understand.
Besides that, I am assuming (without looking at the code too much, it's just a lot to look over), that both players are probably viewing the same inventory. Make sure that each player is getting a custom instance of the inventory and the object is not being shared.

EDIT: okay, they are separate inventories, but otherwise I'm not sure what your problem is. Commenting out things as you write the code is usually the best debugging tool you will ever use, because it allows others to understand what is happening. Try commenting what each line of your code does and you might find the problem.

 

I only know how to speak English
And thank you but this was not coded by me it was coded from a friend of my that quit helping me on this project because it was taking to much time to code!

 

You are doing WAYYYY more than you need to, to code a simple pet GUI.

Start with this :

Code:

Inventory //your inventory name// = Bukkit.createInventory(null, 54, "Pet Shop");

Then when a player right clicks a certain block or something, put this :

Code:

p.openInventory(//your inventory name//);

When you want to add items just do :

Code:

ItemStack //name// = new ItemStack(Material.WHATEVER); inv.addItem(//Item name//);

Always make sure to clear your inventory as soon as the play opens it so it doesn't double all the items :

Code:

inv.clear();

Hope this helped!
