Solved CommandException

Hello Bukkit,

So I'm making a Watch plugin where if people with a permission can watch another player but when the player unwatchs the player I want to teleport them back to the spawn location anyway of doing this so they run the command?

 

You can always

Code:

  player.teleport(player.getWorld().getSpawnLocation());

 

TrollTaylor Thanks

Update to this post:

When I do this

Code:java

        Player target = Bukkit.getServer().getPlayer(args[0]);

For some reason it throws me this when I try to put a player's name in

badboysteee98 Is this on line 24? That is where the error is.

Code:

 Player target = Bukkit.getServer().getPlayer(args[0]);

You did not input any arguments, you must check the argument length, and make sure it is enough to run your command properly, if not, send them a message saying they're using the incorrect syntax.

 

TrollTaylor Yep

Bump

Not enough arguments when you run the command, check if the "args" length is long enough
example

Code:java

if (args.length > 1)
{
    ...
}

 

tryy3 already do that, that is not the problem this is

Code:java

 Player target = p.getServer().getPlayer(args[0]);

Full Code

Code:java

package com.ste.Watch;
 
import org.bukkit.Bukkit;
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 Watch extends JavaPlugin {
 
    public void onEnable() {
        Bukkit.getServer().getLogger().info("[Watched] Enabled!");
    }
 
    public boolean onCommand(CommandSender sender, Command cmd, String label, String[] args) {
 
        if (!(sender instanceof Player)) {
            sender.sendMessage(ChatColor.RED + "You must be a player to do that command");
            return true;
        }
 
        Player p = (Player) sender;
        Player target = p.getServer().getPlayer(args[0]);
 
        if(p.hasPermission("watch.player")) {
            if(args.length < 1) {
                if(cmd.getName().equalsIgnoreCase("watch")) {
                    p.sendMessage(ChatColor.YELLOW + "/watch <player>");
                    return true;
                }
            }
 
            if(target == null) {
                p.sendMessage(ChatColor.RED + "Could not find player " + ChatColor.YELLOW + target);
                return true;
            }
            else {
                if(args.length == 1) {
                p.teleport(target.getLocation());
                p.hidePlayer(p);
                return true;
                }
            }
        }
 
        if(p.hasPermission("unwatch.player")) {
            if(cmd.getName().equalsIgnoreCase("unwatch")) {
                p.showPlayer(p);
                p.teleport(p.getWorld().getSpawnLocation());
                return true;
            }
        }
        return true;
 
    }
 
}
 

 

its giving you an error because args[0] doesn't exists, put the if(args.length < 1) before you make the variable

Code:java

Player target = p.getServer().getPlayer(args[0]);

 

tryy3 Where would I put this? Example if you don't mind? Sorry for asking

 

Code:

if(args.length > 1)
{
    Player target = p.getServer().getPlayer(args[0]);
    ...
}
else
{
    ...
}

 

tryy3 Thank you it works
