There are a few items that can be detected by right-clicking in the air. The `carrot_on_a_stick` and `warped_fungus_on_a_stick` both work. and then all trowable items such as: - ender pearl - eye of ender - lingering potions - Bottle o' Enchanting - splash potions - snowballs - etc. But only the two "on a stick" item can be detected without doing anything. During my testing I also found a few items what is impossible to test for such as: - air - arrow - any kind of dye (even if you dye something like a sheep it doesn't detect it) - bone - and probably some more
