Don't know the right code for this.

Code:java

public class Main extends JavaPlugin {
public boolean onCommand(CommandSender sender, Command cmd, String label, String[] args) {
Bukkit.getServer().broadcastMessage(ChatColor.GREEN + "The player" + getServer().getPlayer(label) + "says hello!");
return true;
}
}

What do I do right here?
(ChatColor.GREEN + "The player" + getServer().getPlayer(label) + "says hello!");
I want it to say the person that sent the command? Also, what do I do if I want to have mulitple commands. Where do I say the command name?
also problem in my plugin.yml

Code:

name: ShoutCraft
version: 1.2 Beta
main: com.endlesswar.ShoutCraft
commands:
  Hello:
    description: Will make you say Hello!

I get this in the console:

You need to build a plugin, with plugin.yml, onEnable, onDisable and various stuff.
Just search for tutorials how to create bukkit plugins.
(If thats all of your code)

 

It seems there's something up with your plugin.yml. The correct format for the plugin.yml can be found here.
Now, as for the rest of your plugin, G4meM0ment was correct, you need at least an onEnable() inside your Main class. Here's a corrected version;

Code:java

public class Main extends JavaPlugin implements CommandExecutor {
public void onEnable()
{
this.getCommand("hello").setExecutor(this);
}
 
public boolean onCommand(CommandSender sender, Command cmd, String label, String[] args) {
Bukkit.getServer().broadcastMessage(ChatColor.GREEN + "The player" + sender.getName() + "says hello!");
return true;
}
}

Code:

name: "ShoutCraft"
version: "1.2b"
main: "com.endlesswar.ShoutCraft"
commands:
  hello:
    description: Will make you say Hello!

 

jackwilsdon No? You don't need to override the onEnable(). It can be left without being overriden and the plugin would work just as good, assuming you don't need something initialized or done when the plugin is enabled. Which is not necessary here, as the main class is by default set as the default executor for all the plugin's commands.

This class also does not need to implement CommandExecutor, by the way, because JavaPlugin does that already.

 

Ah, I did not know this, I apologise. Well, it had something to do with the YML anyway, so I hope my version works

 

evantheis You can get the name of the CommandSender by doing sender.getName()
Line number 4, column 10 in the plugin.yml.....are you sure there is no space behind command: ?

 

first of all, you didn't give your command a name, to do this, let your command look like this : (see the part after if (cmd.getName))

Code:java

public class Main extends JavaPlugin {
public boolean onCommand(CommandSender sender, Command cmd, String label, String[] args) {
if (cmd.getName().equalsIgnoreCase("hello")
Bukkit.getServer().broadcastMessage(ChatColor.GREEN + "The player" + getServer().getPlayer(label) + "says hello!");
return true;

second, you forgot to put in onEnable() and onDisable(), do it like this:

Code:java

public class Main extends JavaPlugin {
@Override
public void onEnable() {
getLogger().info("Some text to say when plugin enables")
}
@Override
public void onDisable() {
getLogger.info("Some text to say when plugin disables")
}
public boolean onCommand(CommandSender sender, Command cmd, String label, String[] args) {
if (cmd.getName().equalsIgnoreCase("hello")
Bukkit.getServer().broadcastMessage(ChatColor.GREEN + "The player" + getServer().getPlayer(label) + "says hello!");
return true;

third, you also have to import all of the methods that aren't defined, and you forgot to define the package: you have to import org.bukkit.ChatColor; ,
import org.bukkit.plugin.java.JavaPlugin;, import org.bukkit.command.Command;, import org.bukkit.command.CommandSender;, org.bukkit.Bukkit;, like this:

Code:java

 
package [FONT=Consolas]com.endlesswar.ShoutCraft.("MainClassName")[/FONT]
 
import org.bukkit.ChatColor;
import org.bukkit.Bukkit;
import org.bukkit.plugin.java.JavaPlugin;
import org.bukkit.command.Command;
import org.bukkit.command.CommandSender;
 
public class Main extends JavaPlugin {
@Override
public void onEnable() {
getLogger().info("Some text to say when plugin enables");
}
@Override
public void onDisable() {
getLogger.info("Some text to say when plugin disables");
}
public boolean onCommand(CommandSender sender, Command cmd, String label, String[] args) {
if (cmd.getName().equalsIgnoreCase("hello"){
Bukkit.getServer().broadcastMessage(ChatColor.GREEN + "The player" + getServer().getPlayer(label) + "says hello!");
return true;
}
return false;
}

and last, to get the playername, you have to add this: sender.getName(), (and you forgot to add spaces, you do it like this: + " ") so this is the final code you should want:

Code:java

 
package [FONT=Consolas]com.endlesswar.ShoutCraft[/FONT]
 
 
import org.bukkit.Bukkit;
import org.bukkit.ChatColor;
import org.bukkit.plugin.java.JavaPlugin;
import org.bukkit.command.Command;
import org.bukkit.command.CommandSender;
 
public class Shout extends JavaPlugin {
@Override
public void onEnable() {
getLogger().info("Some text to say when plugin enables");
}
@Override
public void onDisable() {
getLogger().info("Some text to say when plugin disables");
}
public boolean onCommand(CommandSender sender, Command cmd, String label, String[] args) {
if (cmd.getName().equalsIgnoreCase("hello"));{
Bukkit.getServer().broadcastMessage(ChatColor.GREEN + "The player" + " " + sender.getName() + " " + "says hello!");
return true;
}
}
}
}

and you want the plugin.yml to look like this:

Code:

name: (name you want for the plugin)
main: com.endlesswar.ShoutCraft.main
version: (version you want)
commands:
    hello:
        description: says hello to the server
        usage: /<command>
        permission: (text).(text)

To add more commands to your plugin.yml do this:

Code:

name: (name you want for the plugin)
main: com.endlesswar.ShoutCraft.main
version: (version you want)
commands:
    hello:
        description: says hello to the server
        usage: /<command>
        permission: (text).(text)
  (other command name):
        description: (description)
        usage: /<command> (alternative args)
        permission: (other permission.
and so on................

to add other commands in your class, do it like this (I only used the public boolean part so it was a bit easier to understand):

Code:java

 
public boolean onCommand(CommandSender sender, Command cmd, String label, String[] args) {
if (cmd.getName().equalsIgnoreCase("hello"));{
//do stuff
return true;
}
if (cmd.getName().equalsIgnoreCase(othercommandname){
//do other stuff
return true;
}
return false;
}
 

Hope it helps, say so if you don't understand a part.

 

the @Override thing doesn't matter, since it (in this case) only is used to print a message to your console when it enables/disables the plugin. but did the rest help you?\
no I guess

 

You are the biggest help! Thank you so much!

 

You are welcome!

 

I am actually having a problem. Do you have skype?

 

yup, but I have to go to school, and in the weekend and monady I am away, so tuesday around 3 o clock?

 

Yes what's your username? Also, go to school right now?

 

my username is jcdra1, and my school has finished now, so I have time

 

So did the problem get fixed, because his plugin.yml was missing the 'description' part, so that's what the YAMLParse errors were.

 

Yes, thank you.

 

evantheis I don't have time today, I'm sorry, but you could just post your class and errors and what it should do that it doesn't do, so I can help you right away.
(If you read this before 10:00, you can skype me.)
