I am pretty new to coding java and I have done a few tutorials, which have been great but i don't know why it isn't working in-game. I have tried everything such as changing it and looking at so many different forums. There are two classes for the events(Join and Leave Event) and the main class. I have made sure to check for importing them and errors none for me to see from where I have looked. If anyone can help it would be a blessing.
Code: - Main class:
package me.JimmyClown.FirstPlugin;
import org.bukkit.plugin.java.JavaPlugin;
public class MainClass extends JavaPlugin {
#Override
public void onEnable() {
System.out.println("It works!");
getServer().getPluginManager().registerEvents(new PlayerJoin(), this);
getServer().getPluginManager().registerEvents(new PlayerLeave(), this);
}
#Override
public void onDisable() {
}
}
**Code for the Join-Class:**
package me.JimmyClown.FirstPlugin;
import org.bukkit.ChatColor;
import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.player.PlayerJoinEvent;
public class PlayerJoin implements Listener{
#EventHandler
void onPlayerJoin(PlayerJoinEvent e) {
Player player = e.getPlayer();
e.setJoinMessage(ChatColor.BLUE + "Welcome back to the server!" + player.getDisplayName());
}
}
**Code for Leave Class:**
package me.JimmyClown.FirstPlugin;
import org.bukkit.ChatColor;
import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.player.PlayerQuitEvent;
public class PlayerLeave implements Listener {
#EventHandler
void onPlayerLeave(PlayerQuitEvent e) {
Player player = e.getPlayer();
e.setQuitMessage(ChatColor.DARK_BLUE + "Awwww, We hope we see you soon" + player.getDisplayName());
}
}
The plugin.yml:
name: FirstProject
version: 1.0
main: me.JimmyClown.FirstPlugin.MainClass
authors: JimmyTheClown
description: This is my first plugin.
Try to set the access modifier of the event methods to public.
public void onPlayerLeave(PlayerQuitEvent e) { }
public void onPlayerJoin(PlayerJoinEvent e) { }

So as the title says I need my config file to modify my servers motd, I feel like I've done everything the right way but obviously something is wrong, so let me show you what I'm working with
me.zavage.motd.Main
package me.zavage.motd;
import org.bukkit.plugin.java.JavaPlugin;
public class Main extends JavaPlugin {
#Override
public void onEnable() {
saveDefaultConfig();
}
}
me.zavage.motd.listeners.PingListener
package me.zavage.motd.listeners;
import java.io.File;
import org.bukkit.Bukkit;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.server.ServerListPingEvent;
import me.zavage.motd.Main;
import me.zavage.motd.utils.Utils;
public class PingListener implements Listener {
private Main plugin;
#EventHandler
public void onPing(ServerListPingEvent e) {
e.setMaxPlayers(plugin.getConfig().getInt("maxplayers"));
e.setMotd(Utils.chat(plugin.getConfig().getString("motd" + "\n" + (Utils.chat(plugin.getConfig().getString("motd_line_2"))))));
try {
e.setServerIcon(Bukkit.loadServerIcon(new File(plugin.getConfig().getString("server_icon_path"))));
} catch (Exception e1) {
e1.printStackTrace();
}
}
}
Then we have the config.yml
#can only be a NUMBER with NO DECIMALS!
maxplayers: ''
motd: ''
#next line on motd
motd_line_2:
#create a folder inside the first page of your server files, call it "icon" and drop you server icon in there
#server icon MUST be 64 x 64 pixels
# #NameOfIcon#
#path example "C:\Users\user\Desktop\minecraft test server\icon\icon.png
server_icon_path: ''
If the code that you show if everything that you are using, there is few issues.
You don't register the listener
package me.zavage.motd;
import org.bukkit.plugin.java.JavaPlugin;
public class Main extends JavaPlugin {
#Override
public void onEnable() {
saveDefaultConfig();
getServer().getPluginManager().registerEvents(new PingListener(this), this);
}
}
You don't set the plugin variable in the listener, and you don't have constructor
public class PingListener implements Listener {
private Main plugin;
public PingListener(Main plugin) {
this.plugin = plugin;
}
}
Finally, you are searching for the motd\n motd_line_2 message. You have to use this in your ServerListPingEvent listener :
e.setMaxPlayers(plugin.getConfig().getInt("maxplayers"));
e.setMotd(Utils.chat(plugin.getConfig().getString("motd") + "\n" + plugin.getConfig().getString("motd_line_2")));
try {
e.setServerIcon(Bukkit.loadServerIcon(new File(plugin.getConfig().getString("server_icon_path"))));
} catch (Exception exc) {
exc.printStackTrace();
}
I'm trying to see if someone joined a world and then print something to console but the event doesn't seem to fire. Can someone help me? Here is my code:
package pl00py_TR.pl00pyspvpmod;
import net.minecraft.entity.player.EntityPlayer;
import net.minecraft.init.Blocks;
import net.minecraftforge.common.MinecraftForge;
import net.minecraftforge.event.entity.living.LivingSpawnEvent;
import net.minecraftforge.fml.common.Mod;
import net.minecraftforge.fml.common.Mod.EventHandler;
import net.minecraftforge.fml.common.event.FMLInitializationEvent;
import net.minecraftforge.fml.common.event.FMLPostInitializationEvent;
import net.minecraftforge.fml.common.event.FMLPreInitializationEvent;
import net.minecraftforge.fml.common.eventhandler.SubscribeEvent;
#Mod(modid = Reference.MOD_ID, name = Reference.MOD_NAME, version = Reference.VERSION)
public class Pl00pysPVPMod {
#EventHandler
public void preInit(FMLPreInitializationEvent event) {
}
#EventHandler
public void init(FMLInitializationEvent event) {
}
#EventHandler
public void postInit(FMLPostInitializationEvent event) {
System.out.println("DIRT BLOCK >> " + Blocks.dirt.getUnlocalizedName());
}
public class EventTest {
#SubscribeEvent
public void OnEvent(LivingSpawnEvent event) {
System.out.println("Event Test");
if (event.entity instanceof EntityPlayer) {
System.out.println("Player Joined");
}
}
}
public void RegisterEvents() {
System.out.println("Registering Events...");
MinecraftForge.EVENT_BUS.register(EventTest.class);
}
}
The code is for 1.8.9 and I am trying to find out if someone joins a server/world. I am trying to get the players coords and print them to console but the event doesn't fire or initialize. Could someone explain why this is happening and give me an idea of how to fix this?
Could be wrong but try MinecraftForge.EVENT_BUS.register(new EventTest()); instead of MinecraftForge.EVENT_BUS.register(EventTest.class);
In the documentation for EventBus
void register(java.lang.Object target)
why isn't this working? I don't get any response if I've been killed! So as you can see I have tested multiple ways. But no one is working.
package net.gameforce.testing;
import org.bukkit.Bukkit;
import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.entity.PlayerDeathEvent;
import org.bukkit.event.player.PlayerInteractEvent;
import org.bukkit.plugin.java.JavaPlugin;
public class Main extends JavaPlugin implements Listener {
#Override
public void onEnable() {
getServer().getPluginManager().registerEvents(this,this);
getLogger().info("Testing Plugin Started");
}
public void onDisable() {}
#EventHandler
public void onPlayerInteract(PlayerInteractEvent event){
Bukkit.broadcastMessage("test");
event.getPlayer().setExp(100);
}
public void onPlayerDeath (PlayerDeathEvent event){
Bukkit.broadcastMessage("send");
event.getEntity().getPlayer().setExp(1000);
}
public boolean onDeath (PlayerDeathEvent event) {
Player Player = event.getEntity();
Bukkit.broadcastMessage(Player.getKiller().getDisplayName() + ", has killed you!");
if (Player.getKiller() != null) {
Bukkit.broadcastMessage("No Player");
}
else {
Bukkit.broadcastMessage("IDK");
}
return true;
}
}
Have I done something wrong?
Quotation from http://bukkit.gamepedia.com/Event_API_Reference#.40EventHandler
"Before this method can be invoked by Bukkit when the "Event" is fired, we need to annotate it. We do this with EventHandlers."
You've added this annotation to your onPlayerInteract method, but none of your others, such as your onDeath method. If your listener is setup correctly, adding the #EventHandler annotation to these methods will allow bukkit to correctly invoke them, like so:
#EventHandler
public void onPlayerDeath (PlayerDeathEvent event){
Bukkit.broadcastMessage("send");
event.getEntity().getPlayer().setExp(1000);
}
I'm creating a plugin for bukkit servers, an antiswear one, but i'm trying to not make it case sensitive, how can i do this? code:
package me.Lorenzo.AntiSwear;
import org.bukkit.Bukkit;
import org.bukkit.ChatColor;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.player.AsyncPlayerChatEvent;
import org.bukkit.plugin.java.JavaPlugin;
public class Main extends JavaPlugin implements Listener {
#EventHandler
public void onPlayerChat(AsyncPlayerChatEvent e) {
for(String word : e.getMessage().split(" ")){
if(getConfig().getStringList("bannedwords").contains(word)){
e.setCancelled(true);
e.getPlayer().sendMessage(ChatColor.DARK_RED + "Please don't use that sort of language!");
}
}
}
public void onEnable() {
getConfig().options().copyDefaults(true);
saveConfig();
Bukkit.getServer().getPluginManager().registerEvents(this, this);
}
}
In onEnable, make sure all bannedwords are lowercase.
In onPlayerChat, use e.getMessage().toLowerCase().split(" ") instead of e.getMessage().split(" ")
How about adding toLowerCase():
if(getConfig().getStringList("bannedwords").contains(word.toLowerCase())){
I am trying to create a job in java play2 using akka.
I always get the same error error: cannot find symbol
And it points to system.actorOf() Intellij and Eclipse don't give me an error msg.
But I can not find this method. I used the following imports
import play.libs.Akka;
import akka.actor.ActorSystem;
import akka.actor.ActorRef;
import akka.actor.UntypedActorFactory;
import akka.actor.UntypedActor;
import akka.actor.Props;
import akka.actor.ActorRefFactory;
Maybe the docs are outdated and they have removed the system.actorOf() ?
public class Global extends GlobalSettings {
ActorRef tickActor = system.actorOf(new Props().withCreator(new UntypedActorFactory() {
public UntypedActor create() {
return new UntypedActor() {
public void onReceive(Object message) {
if (message.equals("Log")) {
controllers.Application.log();
} else {
unhandled(message);
}
}
};
}
}));
#Override
public void onStart(Application app) {
Cancellable cancellable = system.scheduler().schedule(Duration.Zero(), Duration.create(10, TimeUnit.SECONDS),
tickActor, "Log");
}
}
EDIT:
.
oh... google redirected me to the outdated documentation. It's Akka.System() now..
Can anyone give me an example on how to create the tickActor with up2date code?
http://www.playframework.org/documentation/2.0.2/JavaAkka
I strongly suggest that you take a look at the Akka documentation about actors and schedulers.
You can also take a look at this question: Play Framework 2.0 schedules an Akka Actor at server launch
solved it.
Btw there are some typos in the documentation.
