Problem with PlayerChatEvent

This is in Bukkit Documentation:
class PlayerChatEvent
Holds information for player chat and commands. More...

But when I run this:

Code:

@EventHandler (priority = EventPriority.LOWEST)
public void onPlayerChat(PlayerChatEvent event) {
        event.getPlayer().sendMessage("Napisales cos na czacie...");
}

it does not work with commands.
Someone has an idea why?

 

Did you remember to register the listener?

 

Use PlayerCommandPreprocess, which is a subclass of PlayerChatEvent. It seems as if chat events are not called for command, even though usually subclasses of an event also call the superclass(es) (e.g. PlayerDeathEvent and EntityDeathEvent both get called when a player dies)

 

Yes, it works with normal message...

It works! Thanks a lot
