Solved command arguments

hey guys!
I'm new in developing a plugin, so i need your help!
I want to make a troll plugin, but i've got to know how to make that all the player's health is being set to 1/20 of it, but that you can also choose one player to 'hit'!
i already have this:

Code:

package me.pipo3090.PPC;

import java.util.logging.Logger;

import org.bukkit.ChatColor;
import org.bukkit.command.Command;
import org.bukkit.command.CommandSender;
import org.bukkit.entity.Player;
import org.bukkit.plugin.java.JavaPlugin;

public class PPC extends JavaPlugin {
    public static Logger logger = Logger.getLogger("Minecraft");
    public static PPC plugin;

  
    public boolean onCommand(CommandSender sender, Command cmd, String commandLabel, String[] args) {
        Player player = (Player) sender;
        if(commandLabel.equalsIgnoreCase("ppc")) {
            player.sendMessage(ChatColor.GREEN + "PRETPARKCRAFT IS AWESOME");
      
            if(commandLabel.equalsIgnoreCase("troll") || commandLabel.equalsIgnoreCase("trololo")){
                if(args.length == 0){
                    //heal = 0 args /heal pipo309 = 1 args
                    player.setHealth(1);
                }else if (args.lenght == 1){
                if  
                }
            }
        }
        return false;
    }
}

you can find other stuff in it, don't mind that
can you guys help me?

greetings,

Cast the second argument as a player like this:

Code:

Player target = Bukkit.getServer().getPlayer(args[0]);
//args[0] is the second argument of a command

now check if the target is an existing player and if the player is online:

Code:

if(target != null || target.isValid) {
   //the player exists
}

Code:

if(target.isOnline()) {
   //the player is online
}

What you want to do now is simply set the health to 1 of the target player:

Code:

target.setHealth(1);

Now you're done!

 

thanks, but i need 1 thing (1d style, i hate it!) more: all players!

 

@pipo3090 Bukkit#getOnlinePlayers() should work, yes?
