[NewAPI] Ban items

Hello, i get a very big problem with ban items on my server. Griefers can use bucket's on server.
I use a many events, but all dont work.

Code:

public function PlayerItemConsumeEvent(PlayerItemConsumeEvent $event){
    $event->setCancelled(true);
}

Code:

public function PlayerItemHeldEvent(PlayerItemHeldEvent $event){
    $event->setCancelled(true);
}

Code:

public function PlayerInteractEvent(PlayerInteractEvent $event){
    $event->setCancelled(true);
}

And in all variants i can place and give bucket(lava, water) in my inventory.
Server in creative mode.

You cancelled all block places?

Yes.

Then you shouldn't be able to place anything.

And it is bucket not Bukkit.

Water and lava are not placed like regular blocks. In the old API, to prevent water and lava from being placed, you had to cancel a player.block.touch event.

He isn't using the place event.

I think that using BlockPlace and BlockDestroy is better.

And how i can ban the bucket?

I don't know. But you can prevent player to get it.

Check if item ID equals bucket. If true cancel event.

I think is possible

LDX just reminded, bucket usages do not trigger the block place event and the block destroy event.

What about PlayerBucketEmptyEvent?
I think that PocketMine Events are same as Bukkit Events

Read the documentation yourself. It is not necessary.

In test, i cancelled all events, without all check's.

I can assume that the whole problem is to intercept onActivate function in /pocketmine/item/Bucket.php

And where is the onActivate function called from? It is from the Level class, right after event PlayerInteractEvent is triggered in the function useItemOn().
