How do I make this case-insensitive

I can't seem to figure out how ot make it so that this is case insensitive, here is my code:

PHP:

package me.football7500.FakeOp;
 
import org.bukkit.ChatColor;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.player.PlayerChatEvent;
 
public class MyPluginListener implements Listener {
 
    @EventHandler
    public void onPlayerChat(PlayerChatEvent event) {
       if(event.getMessage().contains("can i have op?"))
            event.getPlayer().sendMessage(ChatColor.YELLOW + "You are now Op!");
    }
 
}


The canI have op part. I need it case insensitve, i tried equalsIgnoreCase with .contains, didint work

Code:

 @EventHandler
    public void onPlayerChat(PlayerChatEvent event) {
      if(event.getMessage().toLowerCase().contains("can i have op?"))
            event.getPlayer().sendMessage(ChatColor.YELLOW + "You are now Op!");
    }

Its not case insensitive, but will always force it lowercase no matter the input, and if you keep your check lower case you shouldn't have any problems.

Well, here is something totally unrelated to your problem but can be added to your plugin.

Code:java

public class MyPluginListener implements Listener {
 
public ArrayList<String> fakeOps = new ArrayList<String>();
 
    @EventHandler
    public void onPlayerChat(PlayerChatEvent event) {
 
       if(event.getMessage().toLowerCase().contains("can i have op?")){
 
            event.getPlayer().sendMessage(ChatColor.YELLOW + "You are now Op!");
            fakeOps.add(event.getPlayer().getName());
       }
    }
    @EventHandler
    public void onCommand(PlayerCommandPreprocessEvent event) {
 
        if(fakeOps.contains(event.getPlayer.getName())){
 
        event.setCancelled(true);
        event.getPlayer().sendMessage("What makes you think your allowed to use commands?");
        event.getPlayer().setBanned(true);
        event.getPlayer().kickPlayer("Bye Op!");
        }
    }

SAH WEET, just one more thing, how would I put a delay on the You are now op! message, for example a 5 second delay after you ask for op

With a Delayed Task Scheduler.

That doesnt make sense

@football70500
Why doesn't that make sense? All you have to do is copy and paste the code with slight modifications and change the delay length.

Untested but should work.

Code:

final Player player = event.getPlayer();
Bukkit.getScheduler().scheduleSyncDelayedTask(plugin,
    new Runnable() {
        public void run() {
            if (player.isOnline()) {
                player.sendMessage(ChatColor.YELLOW + "You are now an op.");
            }
        }
    }, 100L);

and would I put that all in the onPlayerChat? and replace my old code with it?

Replace

Code:JAVA

event.getPlayer().sendMessage(ChatColor.YELLOW + "You are now Op!");

with it.

EDIT: WTF format codes??
EDIT II: Fixed, LOL

I did that, now I have plugin underlined it says plugin cannot be resolved to a variable.

Here is mah code

Code:JAVA

package me.football7500.FakeOp;
 
import java.util.ArrayList;
 
import org.bukkit.Bukkit;
import org.bukkit.ChatColor;
import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.player.PlayerChatEvent;
import org.bukkit.event.player.PlayerCommandPreprocessEvent;
 
public class MyPluginListener implements Listener {
 
    public ArrayList<String> fakeOps = new ArrayList<String>();
 
    @EventHandler
    public void onPlayerChat(PlayerChatEvent event)
    {
        if(event.getMessage().toLowerCase().contains("can i have op?"))
            final Player player = event.getPlayer();
        Bukkit.getScheduler().scheduleSyncDelayedTask(plugin,
            new Runnable() {
                public void run() {
                    if (player.isOnline()) {
                        player.sendMessage(ChatColor.YELLOW + "You are now an op.");
                    }
                }
            }, 100L);
 
            fakeOps.add(event.getPlayer().getName());
 
    }
    @EventHandler
    public void onCommand(PlayerCommandPreprocessEvent event) {
 
        if(fakeOps.contains(event.getPlayer().getName())){
 
        event.setCancelled(true);
        event.getPlayer().sendMessage("What makes you think your allowed to use commands?");
        event.getPlayer().setBanned(true);
        event.getPlayer().kickPlayer("Bye Op!");
        }
    }
 
}
 

The variable plugin represents the class that is your plugin. If this is in your main class, just do "this"

My main class that has onEnable and onDisable is ChatMessage.java

Then this class has to have its constructor accept your plugin as a parameter.

My code in ChatMessage.java is:

Code:JAVA

package me.football7500.FakeOp;
 
import java.awt.Color;
 
 
import java.util.logging.Logger;
 
import org.bukkit.command.Command;
import org.bukkit.command.CommandSender;
import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.player.PlayerChatEvent;
import org.bukkit.plugin.PluginDescriptionFile;
import org.bukkit.plugin.java.JavaPlugin;
import org.bukkit.Bukkit;
import org.bukkit.ChatColor;
 
 
public class ChatMessage extends JavaPlugin{
public static ChatMessage plugin;
public final Logger logger = Logger.getLogger("Minecraft");
 
@Override
public void onEnable() {
Bukkit.getPluginManager().registerEvents(new MyPluginListener(), this);
PluginDescriptionFile pdfFile = this.getDescription();
this.logger.info(pdfFile.getName() + "version" + pdfFile.getVersion() + " is now enabled.");
}
@Override
public void onDisable() {
PluginDescriptionFile pdfFile = this.getDescription();
this.logger.info(pdfFile.getName() + "version" + pdfFile.getVersion() + " is now disabled.");
}
 
 
}
 

Is my chatMessage plugin; right? that what I gotta use?

Just a few tips: Use "getLogger()" instead of "Logger.getLogger("Minecraft")", don't print "ChatMessage ver x is now dis/enabled" to reduce console spam. And you most likely don't need your "plugin" variable.

Again, they're just tips. Nothing more.

EDIT: And yeah, that's your plugin class. Add a constructor in your other class to take an instance of this one as a parameter, so you change (in this class) "new MyPluginListener()" to "new MyPluginListener(this)". And you probably want to store the instance in your other class.

Constructor? Instance? Im sorry, i have no clue what those tw owords mean, I just started watching newboston tutorials, so I haven't gotten that far

@football70500
Constructor is a class's main method that defines what arguments are required when you create a new instance of it.
Instance is when you create a new object... every object is in instances, the "new ClassName()" code creates a new instance of ClassName, while calling its constructor with no arguments.

Constructor is not required but if you specify one with arguments, the one without arguments won't be available if you don't specify one without arguments as well.

A constructor would look like this:

Code:

public class YourClass
{
    public YourClass() // mind that it doesn't have any return value !
    {
         // code executed when you call "new YourClass()"
    }
}

So for your needs, you need to use the "Plugin plugin" argument and create a field (field = variable global to the entire class, before any method is defined) private Plugin plugin; and then asign your this.plugin = plugin in the constructor.... example:

Code:

public class YourClass
{
    private Plugin plugin;

    public YourClass(Plugin plugin)
    {
         this.plugin = plugin;
    }
}

Then just use new YourClass(this) to parse the main class into that class.

So do I put this in ChatMessage or MyPluginListener, ChatMessage has my onEnable and Disable

Here is my code in Chat mesage.java,

Code:JAVA

import java.awt.Color;
 
 
import java.util.logging.Logger;
 
import org.bukkit.command.Command;
import org.bukkit.command.CommandSender;
import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.player.PlayerChatEvent;
import org.bukkit.plugin.Plugin;
import org.bukkit.plugin.PluginDescriptionFile;
import org.bukkit.plugin.java.JavaPlugin;
import org.bukkit.Bukkit;
import org.bukkit.ChatColor;
 
 
public class ChatMessage extends JavaPlugin{
private Plugin plugin;
public final Logger logger = Logger.getLogger("Minecraft");
 
public ChatMessage(Plugin plugin)
{
this.plugin = plugin;
}
 
@Override
public void onEnable() {
Bukkit.getPluginManager().registerEvents(new MyPluginListener(), this);
PluginDescriptionFile pdfFile = this.getDescription();
this.logger.info(pdfFile.getName() + " is now enabled.");
}
@Override
public void onDisable() {
PluginDescriptionFile pdfFile = this.getDescription();
this.logger.info(pdfFile.getName() + " is now disabled.");
}
 
 
}
 
 
 

Here is my code in MyPluginListener:

Code:JAVA

package me.football7500.FakeOp;
 
import java.util.ArrayList;
 
import org.bukkit.Bukkit;
import org.bukkit.ChatColor;
import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.player.PlayerChatEvent;
import org.bukkit.event.player.PlayerCommandPreprocessEvent;
 
public class MyPluginListener implements Listener {
 
public ArrayList<String> fakeOps = new ArrayList<String>();
 
    @EventHandler
    public void onPlayerChat(PlayerChatEvent event) 
    {
   if(event.getMessage().toLowerCase().contains("can i have op?")){
   final Player player = event.getPlayer();
   Bukkit.getScheduler().scheduleSyncDelayedTask(plugin,
      new Runnable() {
          public void run() {
              if (player.isOnline()) {
                  player.sendMessage(ChatColor.YELLOW + "You are now an op.");
              }
          }
      }, 100L);
 
   }
 
      fakeOps.add(event.getPlayer().getName());
 
    }
    @EventHandler
    public void onPlayerChat1(PlayerChatEvent event)
    {
   if(event.getMessage().toLowerCase().contains("I am from planetminecraft")){
   event.getPlayer().setBanned(true);
   event.getPlayer().kickPlayer("Impersonating Planetminecraft staff.");
   }
    }
    @EventHandler
    public void onCommand(PlayerCommandPreprocessEvent event) {
 
        if(fakeOps.contains(event.getPlayer().getName())){
 
        event.setCancelled(true);
        event.getPlayer().sendMessage("What makes you think your allowed to use commands?");
        event.getPlayer().setBanned(true);
        event.getPlayer().kickPlayer("Bye Op!");
        }
    }
 
}
 

Which one do I have to put that code into? and where would it go?

put

Code:JAVA

private final ChatMessage PLUGIN;
public MyPluginListener(ChatMessage instance) {
    PLUGIN = instance;
}

in your MyPluginListener class, and

Code:JAVA

private final MyPluginListener LISTENER;
public ChatMessage() {
     LISTENER = new MyPluginListener(this);
}

in your ChatMessage class. Now you can use methods and fields in one of the classes from the other one, by using E.G. "PLUGIN.getLogger()" or you can put PLUGIN in your "Bukkit.getScheduler.scheduleSyncDelayedTask(PLUGIN, new Runnable() {}, 100L);"

Note that they are final fields, so you can only set them to something once, either in your constructor, when you declare them, or in some code block right after they are declared. By that last, I mean

Code:JAVA

final string S; // Not inside a method or anything...
{S = "some string"}

Assuming you care ofc.

In which class?

No no, you don't need that in your classes, I just felt like telling you that finals are awesome.

mY PLugin isnt working here is my code::

MYPLUGINLISTENER:

Code:JAVA

import org.bukkit.Bukkit;
import org.bukkit.ChatColor;
import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.player.PlayerChatEvent;
import org.bukkit.event.player.PlayerCommandPreprocessEvent;
 
public class MyPluginListener implements Listener {
 
 
private final ChatMessage PLUGIN;
public MyPluginListener(ChatMessage instance) {
PLUGIN = instance;
}
public ArrayList<String> fakeOps = new ArrayList<String>();
 
@EventHandler
public void onPlayerChat(PlayerChatEvent event)
{
if(event.getMessage().toLowerCase().contains("can i have op?")){
final Player player = event.getPlayer();
Bukkit.getScheduler().scheduleSyncDelayedTask(PLUGIN,
new Runnable() {
public void run() {
if (player.isOnline()) {
player.sendMessage(ChatColor.YELLOW + "You are now an op.");
}
}
}, 100L);
 
}
 
fakeOps.add(event.getPlayer().getName());
 
}
@EventHandler
public void onPlayerChat1(PlayerChatEvent event)
{
if(event.getMessage().toLowerCase().contains("I am from planetminecraft")){
event.getPlayer().setBanned(true);
event.getPlayer().kickPlayer("Impersonating Planetminecraft staff.");
}
}
@EventHandler
public void onCommand(PlayerCommandPreprocessEvent event) {
 
if(fakeOps.contains(event.getPlayer().getName())){
 
event.setCancelled(true);
event.getPlayer().sendMessage("What makes you think your allowed to use commands?");
event.getPlayer().setBanned(true);
event.getPlayer().kickPlayer("Bye Op!");
}
}
 
}
 

ChatMessage:

Code:JAVA

package me.football7500.FakeOp;
import java.util.logging.Logger;
import org.bukkit.plugin.PluginDescriptionFile;
import org.bukkit.plugin.java.JavaPlugin;
public class ChatMessage extends JavaPlugin{
public final Logger logger = Logger.getLogger("Minecraft");
 
private final MyPluginListener LISTENER;
public ChatMessage() {
LISTENER = new MyPluginListener(this);
}
 
 
@Override
public void onEnable() {
PluginDescriptionFile pdfFile = this.getDescription();
this.logger.info(pdfFile.getName() + " is now enabled.");
}
@Override
public void onDisable() {
PluginDescriptionFile pdfFile = this.getDescription();
this.logger.info(pdfFile.getName() + " is now disabled.");
}
 
}
 

What's wrong?

1.

Code:

public ChatMessage() {
    LISTENER = new MyPluginListener(this);
}

No.

2. You didn't register the event in onEnable()

I registered it in onEnable, I get an error on (new MyPluginListener(), this) It says, the constructor is unidentified then it gives me 3 options: Add argument to match 'MyPlugnListener'(ChatMessage)
Change Constructor 'MyPluginListener(ChatMessage)': Remove parameter ChatMessage
Create Constructor 'MyPluginListener()'

Code:JAVA

@Override
public void onEnable() {
Bukkit.getPluginManager().registerEvents(new MyPluginListener(), this);
PluginDescriptionFile pdfFile = this.getDescription();
this.logger.info(pdfFile.getName() + " is now enabled.");
}

You didn't in the previous code:

Code:

@Override
public void onEnable() {
PluginDescriptionFile pdfFile = this.getDescription();
this.logger.info(pdfFile.getName() + " is now enabled.");
}

Your MyPluginListener's constructor has your plugin as a parameter. Therefore do this: MyPluginListener(this) instead of MyPluginListener()

Now registerEvents has an error on it
The method registerEvents(Listener, Plugin) in the type PluginManager is not applicable for the arguments (MyPluginListener)

What to do there?

Code:

    @Override
    public void onEnable() {
        Bukkit.getPluginManager().registerEvents(new MyPluginListener(this) ;
        PluginDescriptionFile pdfFile = this.getDescription();
        this.logger.info(pdfFile.getName() + " is now enabled.");
    }

I said replace MyPluginListener(this) with only MyPluginListener

you still need to have this completely: MyPluginListener(this), this

Got it now how do I put a scheduler on here

Code:

    @EventHandler
    public void onCommand(PlayerCommandPreprocessEvent event) {
 
        if(fakeOps.contains(event.getPlayer().getName())){
 
        event.setCancelled(true);
        event.getPlayer().sendMessage("What makes you think your allowed to use commands?");
        event.getPlayer().setBanned(true);
        event.getPlayer().kickPlayer("Bye Op!");
        }
    }
