PlayerBanEvent

While I realize that PlayerBanEvents aren't real, I would like to know how to program the equivalent of one. How can I tell when a player is banned or unbanned?

Well, we can code a work around

Here is what I came up with in 5 minutes

PHP:

public function onPlayerCommand(PlayerCommandPreprocessEvent $event){
        $player= $event->getPlayer();
        $message = $event->getMessage();
        $command = substr($message, 1);
        $args = explode(" ", $command);
        if($args[0] === "ban-ip" or $args[0] === "ban"){ //commands
            if (substr($message, 0, 1) === '/') { //Double check to make sure its a command.
                $event->getPlayer()->sendMessage("- xFlare stoped this command with magic.");
                $event->setCancelled(true);
                return true;

He wants to know how to to get if player is banned or not.

That works for the ban command, but I also want to catch when a plugin calls the Player::setBanned() method.

No, he had it right. You can check if a player is banned by calling the Player::isBanned() method.

Then why ask if u know -,-

When, not if. ;^) #MajorLeagueEnglish

PlayerKickEvent::getReason() or something like that.
