Cannot resolve method 'getTitle' in 'Inventory' when click event
(1 answer)
Closed 6 days ago.
Im trying to make a minecraft anti cheat with bukkit. my server version is 1.18.
but i seem to get this error;
java: cannot find symbol symbol: method getTitle() location: variable inventory of type org.bukkit.inventory.Inventory
here is the segment of code that error is referring about;
if (inventory.getTitle().equals("Flagged Players")) {
full segment of code (Not entire file of code):
package anticheat.anticheat;
import java.util.HashMap;

public class Anticheat implements Listener {
private Map<Player, Boolean> flaggedPlayers = new HashMap<>();
private Map<Player, Inventory> flaggedPlayersInventory = new HashMap<>();

public void onPlayerMove(PlayerMoveEvent event) {
Player player = event.getPlayer();
if (isUsingFlyHack(player)) {
// Flag the player and kick them from the server
flagPlayer(player);
player.kickPlayer("Using fly hacks is not allowed on this server");
}
}
#EventHandler
public void onInventoryClick(InventoryClickEvent event) {
Player player = (Player) event.getWhoClicked();
Inventory inventory = event.getInventory();
if (inventory.getType() == InventoryType.CHEST) {
if (inventory.getTitle().equals("Flagged Players")) {
ItemStack item = event.getCurrentItem();
SkullMeta meta = (SkullMeta) item.getItemMeta();
Player flaggedPlayer = Bukkit.getPlayer(meta.getOwningPlayer().getName());
// Check if the clicked item is a player head
if (item.getType() == Material.PLAYER_HEAD && flaggedPlayers.get(flaggedPlayer) != null) {
}
event.setCancelled(true);
}
}
}
I have tried to replace .getTitle with .getName using the code bellow
if (inventory.getTitle().equals("Flagged Players")) {
But that didn't fix it and gave me the same error.
**I have also tried **
if (inventory.getType() == InventoryType.CHEST && inventory.getTitle().equals("Flagged Players")) {
But also gave me the same output.
The method getTitle was removed from Inventory.
You can access that value in your code using:
event.getView().getTitle()

I am currently learning how to program minecraft mods using fabric. I want to create an Item, which, when used on a creeper, let the player explode, which will also be shown in the deathmessage, that the player was the cause of the death(like when you kill yourself with TNT).
package net.lurchfresser.tutorialmod.item.custom;
import net.minecraft.entity.Entity;
import net.minecraft.entity.LivingEntity;
import net.minecraft.entity.damage.DamageSource;
import net.minecraft.entity.effect.StatusEffect;
import net.minecraft.entity.effect.StatusEffectInstance;
import net.minecraft.entity.mob.CreeperEntity;
import net.minecraft.entity.mob.ZombieEntity;
import net.minecraft.entity.player.PlayerEntity;
import net.minecraft.item.Item;
import net.minecraft.item.ItemStack;
import net.minecraft.potion.Potion;
import net.minecraft.util.ActionResult;
import net.minecraft.util.Hand;
import net.minecraft.world.World;
import org.w3c.dom.Text;
public class ConsumerItem extends Item {
public ConsumerItem(Settings settings){
super(settings);
}
#Override
public ActionResult useOnEntity(ItemStack stack, PlayerEntity user, LivingEntity entity, Hand hand) {
double x = user.getX();
double y = user.getY();
double z = user.getZ();
if(!user.world.isClient) {
if (entity instanceof ZombieEntity) {
entity.kill();
user.addStatusEffect(new StatusEffectInstance(StatusEffect.byRawId(19), 100));
} else if (entity instanceof CreeperEntity) {
entity.kill();
user.world.createExplosion(user, null,null, x + 0.5D, y + 0.5d, z + 0.5d,3F,false,World.ExplosionSourceType.MOB);
}
}
return super.useOnEntity(stack, user, entity, hand);
}
}
If I put the creeper in the first param of the createExplosion method. The Creeper will be the cause of the death. Also trying pass user.getName.toString in the second param(damageSource) didn't work out.
I am trying to make a plugin where when a certain block in the GUI is clicked, a command is run. The problem is, I have to transfer a string from one method to another. I don't have very much java knowledge, so if someone could teach me how to do this, I would very much appreciate it.
P.S. The string I am trying to use is called custompermscommand.
Code:
package me.eliminiquated.yugengrant;
import org.bukkit.Bukkit;
import org.bukkit.ChatColor;
import org.bukkit.Material;
import org.bukkit.command.Command;
import org.bukkit.command.CommandExecutor;
import org.bukkit.command.CommandSender;
import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
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 java.util.ArrayList;
public class Grant implements CommandExecutor, Listener {
#Override
public boolean onCommand(CommandSender sender, Command command, String label, String[] args) {
if (command.getName().equals("grant")){
if (sender instanceof Player){
Player player = (Player) sender;
if (player.hasPermission("yugen.grant")){
if (args.length == 1){
player.sendMessage("Incorrect Usage! </grant (username)>");
}else if (args.length == 2){
Inventory gui = Bukkit.createInventory(player, 27, ChatColor.DARK_GREEN+"Grant Menu");
ItemStack custom = new ItemStack(Material.ORANGE_GLAZED_TERRACOTTA);
ItemStack playerranks = new ItemStack(Material.LAPIS_BLOCK);
ItemStack staffpositions = new ItemStack(Material.REDSTONE_BLOCK);
ItemMeta custommeta = custom.getItemMeta();
ItemMeta playerranksmeta = playerranks.getItemMeta();
ItemMeta staffpositionsmeta = staffpositions.getItemMeta();
custommeta.setDisplayName(ChatColor.GOLD+"Custom");
ArrayList<String> custom_lore = new ArrayList<>();
custom_lore.add(ChatColor.GRAY+""+ChatColor.ITALIC+"Coming soon");
custommeta.setLore(custom_lore);
custom.setItemMeta(custommeta);
playerranksmeta.setDisplayName(ChatColor.AQUA+"Player Ranks");
playerranks.setItemMeta(playerranksmeta);
staffpositionsmeta.setDisplayName(ChatColor.RED+"Staff Positions");
staffpositions.setItemMeta(staffpositionsmeta);
gui.setItem(10, custom);
gui.setItem(12, playerranks);
gui.setItem(14, staffpositions);
player.openInventory(gui);
String custompermscommand = "grantcustomperms "+args[0]+"";
}else{
player.sendMessage("Incorrect Usage! </grant (username)>");
}
}else{
player.sendMessage(ChatColor.RED+"You do not have permission to execute this command!");
}
}
}else{
System.out.println("You must be a player to execute this command");
}
return false;
}
#EventHandler
public void onInventoryClick(InventoryClickEvent event){
Player player = (Player) event.getWhoClicked();
if (event.getClickedInventory().getTitle().equalsIgnoreCase(ChatColor.DARK_GREEN+"Grant Menu")){
if (event.getCurrentItem().getType() == Material.ORANGE_GLAZED_TERRACOTTA){
Bukkit.dispatchCommand(player, custompermscommand);
}
}
}
}
For anyone that wants to do this themselves, this is the answer:
First, declare the variable as public outside of the methods:
Example:
public String command;
Next, edit the string inside of the method that you want to grab the string from:
Example:
command = args[0];
Finally, you are able to call this string in whatever method you want:
Example:
Bukkit.dispatchCommand(player, command);
So Basically I have been searching the internet for a way to add potion effects while an item is being held. I have found many results but none really seem to be working. My main issue is that when I get to the adding potion effect it throws errors because I am trying to use a non-static to access an abstract. I tried the #Overide several times but it never seems to work. I still need to register in forge as that is how it updates but adding PlayerEntity does not work when I use #SubscribeEvent

That is my code for basically my whole mod, can anyone give me any pointers? (Sorry for any mistakes this is my first post)
I have made a plugin that is supposed to track the amount of diamonds you have mined in Minecraft and save it to a config.yml file. But my code doesn't seem to be working and I cant figure out why?
I've already tried +1 in the setConfig args and now I've switched over to this and it still doesn't seem to be working. I also have diamonds predefined in my config.yml file.
package com.raidoxe.BlockPlugin;
import org.bukkit.ChatColor;
import org.bukkit.command.Command;
import org.bukkit.command.CommandSender;
import org.bukkit.entity.Player;
import org.bukkit.plugin.PluginManager;
import org.bukkit.plugin.java.JavaPlugin;
public class Main extends JavaPlugin {
#Override
public void onEnable() {
getLogger().info("Sartu has been enabled :)");
PluginManager pm = getServer().getPluginManager();
SartuListener listener = new SartuListener(this);
pm.registerEvents(listener, this);
this.getConfig().options().copyDefaults(true);
this.saveConfig();
}
public boolean onCommand(CommandSender sender, Command cmd, String label, String[] args) {
Player player = (Player) sender;
if (sender instanceof Player) {
String lowerCmd = cmd.getName().toLowerCase();
switch (lowerCmd) {
case "mydiamonds":
int a = this.getConfig().getInt("diamonds."+player.getUniqueId());
player.sendMessage(ChatColor.DARK_PURPLE+"You have mined "+ChatColor.RED+a+ChatColor.AQUA+" Diamonds");
return true;
}
}
return true;
}

public void blockBreak(BlockBreakEvent event) {
Player player = (Player) event.getPlayer();
Block block = event.getBlock();
Material blockMaterial = block.getType();
if(blockMaterial.equals(Material.DIAMOND_ORE)) {
Bukkit.broadcastMessage(ChatColor.WHITE+player.getDisplayName()+" found a "+ ChatColor.AQUA + ChatColor.BOLD+"Diamond!!!");
int a = plugin.getConfig().getInt("diamonds."+player.getUniqueId());
plugin.getConfig().set("diamonds."+player.getUniqueId(), a++);
plugin.saveConfig();
}
}
when the player does the command /mydiamonds it should print out, "you have mined (a) diamonds". But it always prints out zero, no matter how many diamonds you have mined.
Your code seems to be looking fine except one minor mistake. You say that you've tried +1 in the setConfig, so if this solution does not work for you it's probably a version thing
If a config getInt() returns 0 it can mean two things:
value does not exist (default is returned)
value is actually 0 in the config
Upon testing the value does exist in the config (due to saveConfig(), but is set to 0. So this lead me to the setting method.
The issue is the adding part. You do a++ inside the method, this will increment the number after the method, we want before, switch to ++a. See this post.
if(blockMaterial.equals(Material.DIAMOND_ORE)) {
Bukkit.broadcastMessage(ChatColor.WHITE+player.getDisplayName()+" found a "+ ChatColor.AQUA + ChatColor.BOLD+"Diamond!!!");
int a = plugin.getConfig().getInt("diamonds."+player.getUniqueId());
plugin.getConfig().set("diamonds."+player.getUniqueId(), ++a);
plugin.saveConfig();
}

As far as the NullPointerException you provided goes, this is the line that causes the error:
String action = HiddenStringUtils.extractHiddenString(lore.get(0));
You should be able to check why it results in a NullPointerException.
I guess the event-error you get will be resolved as soon as you fix your code.
Also the first link you provided does not work without being logged in.
