There is a NullPointerException at line 34 in the IconMenu class.
Try to create the menu at the event.

 

remove the private before Icon menu.
you are creating a method not referring to the IconMenu class

 

IconMenu class:

Code:java

 
import java.util.Arrays;
import org.bukkit.Bukkit;
import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.EventPriority;
import org.bukkit.event.HandlerList;
import org.bukkit.event.Listener;
import org.bukkit.event.inventory.InventoryClickEvent;
import org.bukkit.inventory.Inventory;
import org.bukkit.inventory.ItemStack;
import org.bukkit.inventory.meta.ItemMeta;
import org.bukkit.plugin.Plugin;
 
public class IconMenu implements Listener {
 
private String name;
private int size;
private OptionClickEventHandler handler;

this.optionNames = new String[size];
this.optionIcons = new ItemStack[size];
plugin.getServer().getPluginManager().registerEvents(this, plugin);
}
 
 
public IconMenu setOption(int position, ItemStack icon, String name, String... info) {
optionNames[position] = name;
optionIcons[position] = setItemNameAndLore(icon, name, info);
return this;
}
 
public void open(Player player) {
Inventory inventory = Bukkit.createInventory(player, size, name);
for (int i = 0; i < optionIcons.length; i++) {
if (optionIcons != null) {
inventory.setItem(i, optionIcons);
}
}
player.openInventory(inventory);
}
 
public void destroy() {
HandlerList.unregisterAll(this);
handler = null;
plugin = null;
optionNames = null;
optionIcons = null;
}
 
@EventHandler(priority=EventPriority.MONITOR)
void onInventoryClick(InventoryClickEvent event) {
if (event.getInventory().getTitle().equals(name)) {
event.setCancelled(true);
int slot = event.getRawSlot();
if (slot >= 0 && slot < size && optionNames[slot] != null) {
Plugin plugin = this.plugin;
OptionClickEvent e = new OptionClickEvent((Player)event.getWhoClicked(), slot, optionNames[slot]);
handler.onOptionClick(e);
if (e.willClose()) {
final Player p = (Player)event.getWhoClicked();
Bukkit.getScheduler().scheduleSyncDelayedTask(plugin, new Runnable() {
public void run() {
p.closeInventory();
}
}, 1);
}
if (e.willDestroy()) {
destroy();
}
}
}
}
 
public interface OptionClickEventHandler {
public void onOptionClick(OptionClickEvent event);
}
 
public class OptionClickEvent {
private Player player;

}
 
public Player getPlayer() {
return player;
}
 
public int getPosition() {
return position;
}
 
public String getName() {
return name;
}
 
public boolean willClose() {
return close;
}
 
public boolean willDestroy() {
return destroy;
}
 
public void setWillClose(boolean close) {
this.close = close;
}
 
public void setWillDestroy(boolean destroy) {
this.destroy = destroy;
}
}
 
private ItemStack setItemNameAndLore(ItemStack item, String name, String[] lore) {

im.setDisplayName(name);
im.setLore(Arrays.asList(lore));

}
 
}
 

Main class:

Code:java

 
public class Novaclass extends JavaPlugin implements Listener{
public void onEnable() {
IconMenu testmenu =new IconMenu("Test", 9, new IconMenu.OptionClickEventHandler() {
@Override
publicvoid onOptionClick(IconMenu.OptionClickEvent event) {
event.getPlayer().sendMessage("Test: "+ event.getName());
event.setWillClose(true);
}
}, this)
setOption(3, new ItemStack(Material.PAPER, 1), "test", "test")
setOption(4, new ItemStack(Material.WRITTEN_BOOK, 1), "test", "test")
setOption(5, new ItemStack(Material.EMERALD, 1), "test", "test");
 
PluginManager pm = this.getServer().getPluginManager();
pm.registerEvents(this, this);
 
}
 
@Override
public boolean onCommand(CommandSender sender, Command cmd, String label, String[] args) {
if(cmd.getName().equalsIgnoreCase("test2")){
testmenu.open((Player)sender);
return true;
}
return false;
}
}
 

testmenu cannot be resolved(23line)

 

Because it is in a method so can't be accessed from other methods. Put it like this:

Code:java

//NOT in onEnable:
IconMenu testmenu;
 
//IN onEnable():
testmenu = new IconMenu(...); //replace with your parameters

 

Really helped, THANKS!!!!!
