Set kick message?

How do you change the default kick message? Is overidding the only way? If yes, can someone give me an example?

$player->kick("message", false); you can use this in events which kicking players

Did you try PlayerKickEvent's setQuitMessage?

do you think message which show to client only or messages like "player left the game"?

I did. It did not work...

which messages do you mean? message which display to player "kicked by admin Reason: ddfff" or Join and Quit messages?

It works but the problem is that I use "PlayerKickEvent", so I can not just use kick();

A trick to avoid that:
Let $main be the instance of your main class.
For kicking code:

PHP:

$main->_WeAreKicking = true;
$player->kick($message, false);
$main->_WeAreKicking = false;


For handler code:

PHP:

public function onKick(PlayerKickEvent $ev){
  if($main->_WeAreKicking) return;
  // normal code for handling kicking
}


Since most of the things in PocketMine are single-threaded, this method can be used.

"Normal code for handling kicking"
What do you mean by that?
