How to do it?

Can you (or someone else ) write or give link for an example about use this event?

 

PS: My mod will no support servers

Ok, I have used ConnectionHandler, but I have error with:

 

public void playerLoggedIn(Player player, NetHandler netHandler, INetworkManager manager)
{
	player.triggerAchievment(achievements.Adwenture, 1);
}

Ok, I done

 

	public void playerLoggedIn(Player player, NetHandler netHandler, INetworkManager manager)
{
	netHandler.getPlayer().addStat(achievements.Adwenture, 1);
}
