This library is completely re-coded.

https://www.spigotmc.org/resources/userinterfacelib2.25351/

this plugin must be used with ProtocolLib

i'm not sure if the same thing happens in spigot server, cancelling the inventoryclickevent in craftbukkit server has a bug: if a player shift+click the GUI icon fast enough and close the GUI 'before' the item actually going back to its original place, the item remains at player's inventory. I'm using ProtocolLib to control this glitch

usage:

there are two classes you have to aware of: GUIInterface and GUIObject

GUIInterface represents the GUI itself and GUIObject is what you can add in your GUI. GUIObject is flextible since you can set your own handler.

examples)

1. check if the UserInterfaceLib is enabled

if(pm.getPlugin("UserInterfaceLib").isEnabled()){
this.userInterfaceLibEnabled = true;
this.userInterfaceLib = (UserInterfaceLib) pm.getPlugin("UserInterfaceLib");
}

something like this

2. create your GUIInterface

GUIInterface gui = UserInterfaceLibAPI.createNewGUI("RPGStatManagement", 9);

first argument is the name of interface, and second argument is the size of the inventory. size must be multiple of 9

3. as you already noticed, you can add InterfaceOpenCloseHandler if you want.

gui.setOpencloseHandler(new InterfaceOpenCloseHandler(){
@Override
public void onOpen(Player player) {
player.sendMessage("you opened a GUI

");
}
@Override
public void onClose(Player player) {
player.sendMessage("you closed the GUI :/");
}
});

or just don't set anything if you don't want to handle open close events

4. and now you can make GUIObject
GUIObject btn = UserInterfaceLibAPI.createNewGUIObject(new ItemStack(Material.ENCHANTED_BOOK), gui);

the first argument is the itemstack that will be used as the GUI's object, and the second argument is the GUIInterface where you gonna add your object.

and don't forget to add object into interface!

gui.addGUIObject(row, col, btn);

5. you added your object in you interface, now you have to add handlers for your object.

there are three types of handlers: ClickEventHandler, DropEventHandler, and KeyPressEventHandler.

btn.setClickEventHandler();
btn.setDropEventHandler();
btn.setKeyPressEventHandler();

are the method you have to use to set handlers

the coding part is exactly same as openclose handler of GUIInterface so i will skip the example part

6. now you are all set! but how to open this GUIInterface to users?

very easy

use the method of GUIInterface called toBukkitInv() removed
use the method of GUIInterface called showGUIto(Player)

for example) gui.showGUIto(player);

and this is the part of onCommand where I show GUI to users

Code (Text):

RPGSurvival.getUserInterfaceManager().createGUIStatManager(user).showGUIto(player);
}else{
statExplaination(player);
