Solved Torch`s values to a Stick.

Hi guys! I really can`t find an answer. So please help me!
I need to make so that if Player clicked on the block there would place a torch. It is simple. But if the block, which were clicked, was something as leaves or grass? The torch would drop as an item...
That`s my problem(

 

Search for a blockupdate event and try canceling that.

PlayerInteractEvent()
rclick air || rclick block
if clicked block = blah
place torch/dont place

Ummm.. I don`t get. What`s mean "if clicked block = blah"??? And how can I do it?

 

He gave you psuedocode, and I presume that 'blah' can mean any block that you want.

 

Ok.. I thought there are any other variants of this problem..
