How to send a message to a player (Not player who ran command)

I need to send a message to a different player than sent the command. Lets see the command is /w <player> . How can I send a message to the <player> that was specified?

 

This is really easy...
Just check that the first argument isn't null then run Server::getPlayer on it, which returns a Player object(if it doesnt fail).

 

Code for what @applqpak said

PHP:

$player = $this->getServer()->getPlayer($args);
if($player->isConnected()){
$player->sendMessage("Hello!");
}else{
$sender->sendMessage("Player isn't online!");
// "$sender" is the command sender
}


 

Thanks!

 

As far as I know Server::getPlayer() returns null if no player was found, which also means $player->isConnected() won't work in that case.
That's how I would solve it:

PHP:

 if($player instanceof Player){} 

or

PHP:

 if($player !== null){} 

Besides that +1
