How can you test in Minecraft in a scoreboard if you right click with a carrot on stick WITH TAG?
In 1.14.4
Simply by checking whether the CarrotOnAStick has the day you want:
execute if entity @p [nbt = {SelectedItem: {id: "minecraft: carrot_on_a_stick", Count: 1b, tag: {tag: 1b}}}] run say abc
Very good answer
Thank you!
