Antihack for antiknockback?

Is it possible to create antihack for antiknockback?

 

getKnockBack in entitydamageevent does not help. Lots of hack clients knockback player fast and then teleport to the previsious position

 

Yes, but it is not too easy

 

I know xD

 

Nope.
as if you "can" do it, how about if a player lags? will you force knockback him?
That's the reason of how hard to block hacks.

 

What about this code?

PHP:

public function idk(PlayerMoveEvent $e)
    {
        $p = $e->getPlayer();
        $from = $e->getFrom();
        $to = $e->getTo();
        $knockdistance = $from->distance($to);
        if ($knockdistance > 2.5) {
            $this->teleport[$p->getName()] = $p->getName();
        } elseif ($knockdistance < 1.1) {
            if (isset($this->knockback[$p->getName()])) {
                if (isset($this->teleport[$p->getName()])) {
                    $p->kick("AntiKnockback:D", false);
                }
            }
        }
    }

    public
    function onDamage(EntityDamageEvent $e)
    {
        $p = $e->getEntity();
        if ($e instanceof EntityDamageByEntityEvent) {
            if ($e->getKnockBack() > 2.5) {
                if (isset($this->teleport[$p->getName()])) {
                    $this->knockback[$p->getName()] = $p->getName();
                }
            }

        }
    }
}

I do not have time to test now.. Can it be usable?

 

It would depend on what the rest of your code is.
