Story

I am creating a chatbot using commands in Minecraft. A grid of buttons representing letters and numbers is on a wall. The player can press these buttons to "type" letters into their query to the chatbot. Each letter is typed by adding a string with that letter to the end of an NBT array. For example, when the ‘L’ button is pressed, this command is run:

data modify storage chatbot:main CurrentEntry append value "L"

For example, a completed query array for the query "Life is a bowl of cherries" might look like this:

{CurrentEntry:["L","i","f","e"," ","i","s"," ","a"," ","b","o","w","l"," ","o","f"," ","c","h","e","r","r","i","e","s"]}

Once the user is finished entering a query into the machine, they press the Submit button, which starts the analyzing process and allows the chatbot to give an answer.

Problem

I’m in the phase where I’m developing easter eggs, where a specific phrase can be typed into the chatbot to produce a unique response. To do this, I am going to need to concatenate each value in the query array in order to produce a single string with the full query, and then compare that with a template string to see if it matches an easter egg phrase.

Concatenating strings in Minecraft will probably be quite of a hassle. The approach I’ve chosen to take is to concatenate the first two strings, then concatenate the result with the next string, and so on until I’ve reached a final string of the entire query.

Core question

How do you concatenate two or more strings from NBT data?

Given two strings in NBT:

{String1:"Life is a ",String2:"bowl of cherries"}

can you concatenate them to produce:

{ResultString:"Life is a bowl of cherries"}

Past trials

1. I had the idea of using /data modify to append to strings, but it is only for adding to lists, not adding to strings.
