block right click crash and question

I have written an block which plays the anvil sound when it gets

right clicked with a certain item, however I crash out of the game when I right click with

an empty hand.

 

As long as I click it with a hammer it works as intended, but if I click

with nothing in my hand the client crashes with a nullpointer exception,

and I can't figure out why.

It's probably something simple that i've missed.

 

Block class is here:

The block in question is an anvil and the item is a hammer. The idea for the block is to act similar to a crafting table but with the

recipe only completing after you whack the anvil enough times.

 

So my other question aside from the crash problem is this:

If I hold right click it spams the onRightClick method, and plays the sound repeatedly.

 

How would I set up a delay so you can't hold right click on the block?
