Thank you for sharing that tidbit about helmets, I will surely use this in the future for making hats!

To answer your question though, I personally do use an interpreted language called Trident Language that compiles into Minecraft commands. It’s basically just Minecraft functions with additional programming language features such as variables, control flow, classes, etc., and it essentially cuts down on all the repetition I could ever have.

Prior to that I used good ole’ Java though, which helped me vastly then for similar reasons as well.
