Solved Setting a players location

I'm trying to make a plugin with basic troll commands. One of the commands is /void which is supposed to teleport a player to the void right under their location. For some reason I'm getting an error when I try to execute the command. Here's the onCommand:

Code:java

public boolean onCommand(CommandSender sender, Command cmd, String label, String[] args){
            if (cmd.getName().equalsIgnoreCase("void")){
 
            Player target = (Bukkit.getServer().getPlayer(args[0]));
                if (target == null) {//Checks to see if the target is online
                    //If the target is not online
                  sender.sendMessage(args[0] + " is not online!");
                  return false;
                }
                else {//If the target is online
                    double x = target.getLocation().getX();
                    double z = target.getLocation().getZ();
                    Location voidUnderPlayer = null;
                    voidUnderPlayer.setX(x);
                    voidUnderPlayer.setZ(z);
                    voidUnderPlayer.setY(0);
                    target.teleport(voidUnderPlayer);
 
                }
            }
                return false;
        }

 

Code:java

Location voidUnderPlayer = null;
voidUnderPlayer.setX(x);
voidUnderPlayer.setZ(z);
voidUnderPlayer.setY(0);

Are you serious? ...
If you don't know what null means you should realy start on some basic Java Tutorials...

 

Like Noxyro said, if you don't know how to use null then you should probably check out some basic Java tutorials before trying to learn the Bukkit API.

Change:

Code:java

Location voidUnderPlayer = null;
voidUnderPlayer.setX(x);
voidUnderPlayer.setZ(z);
voidUnderPlayer.setY(0);

to:

Code:java

Location voidUnderPlayer = new Location(target.getWorld(), x, 0, z);

or even:

Code:java

Location voidUnderPlayer = target.getLocation();
voidUnderPlayer.setY(0);
