Title says a lot of it. I'm looking for a way to get the itemstack of a block that is about to be placed with the BlockPlaceEvent#getItemInHand function. I believe getItemInHand will accomplish this, but I'm not sure how this works with the second hand implemented with 1.10. Does that change to the itemstack in the placing hand, or always the primary? I tried it myself but I couldn't really get an answer. EDIT: It appears after testing it more I am right, but I still cant find any documentation on it.
