Solved setType and drop

Hey. I have a problem. With setType and using the BED, it disappears, leaving the second part of the drop. How can I destroy an entire bed without a drop? I understand that you need to check the next bed, but you can suffer a bed near, which is not involved in this.

 

There is a face and direction to get there, but I need to go through the bed ... How?

 

Is there a way to get a face on which one to point out? Is there also isHeadofBed, but check every block? This is a trouble. Yes, and how do I do under the bed? A conventional unit does not have this capability.

I mean, what do I need to create a separate BED block?

 

Can I get these BED functions on another block?

 

Throw?

So, what is next?
After all, it will be stupid to check each BlockFace block, the more it will be possible to hurt the other ...

 

I did not understand. And what should I do with the location and face of the block?
