i know about event, but how i do this, i forget the name to cancel the event

Code:java

    @EventHandler
    public void b (BlockBreakEvent e){
        final Player p = e.getPlayer();
        if (p.hasPermission("break.cant.break")){
            // what i do here?
        }
    }
}

 

e.setCancelled(true);

Also makes more sense if you check: if(!p.hasPermission("permission") {
