There is a question on this website on how to use an item in your off-hand. How to use an item in my off-hand?
Thanks for the explanation there.
My question however is how to NOT use this item. Running around in the dark with a lamp in my off-hand, sometimes the lamp is placed on right click, and I don't have a pickaxe or something to break it to retrieve it.
Is there a way to prevent off-hand items being placed when there is no right-click function or an empty right hand?
