Have you ever seen an entire machine appear in your Minecraft world out of nothing but a single command block? Well, you could do that too! This is a basic tutorial on how to create one of my One Command Machines!
I hope this video gives you an idea of how I create my commands and helped you a bit as well! As I said in the video already, I prefer to write all my commands by hand. It gives me a free hand for... everything! Nevertheless, using the tools / generators listed down below is also a good alternative! =)
