Ruby Blocks: modify the yield statement to send the monster instance to a block...

I hope I am not the only one who is completely confused by the last code challenge in the Ruby blocks section. I thought I understood what I had to do but nothing seems to work.

Here's what Treehouse asks us to do: "In the scream method, modify the yield statement to send the monster instance to a block if a block is sent in to the scream method."

I've added 'monster' and even 'Monster.new("Fluffy") after the 'yield' keyword. One would think this is what's meant by "the monster instance."

Any suggestions?

Thanks.

You're sorta on the right track.

if you were to add Monster.new after yield, you'd be sending a brand new, untouched, unnamed (probably wouldn't work) to the block.

Instead, you're asked to send the current Monster instance to a block if a block is sent to the scream method. In this case you'd use the self keyword along with the block_given? method that Jason shows in the previous video.

yield self if block_given?

Thanks Ricardo. I appreciate the help. I'll have to rewatch that portion of the video.

No problem. I just finished that course earlier today, and it certainly was not easy.
