So. What is a level? Because it sure ain’t “plain” data as you seem to claim.
It’s an idea. Two implementation of Sokoban can have the same level despite not sharing and code or any data.
What the. What? You make no sense at all here.
Interpreting is not displaying it to a user or downloading. Interpreting is a synonym for executing code that is human readable. Usually seen in scripting languages. But a video game does just the same. It interprets your “plain data” as a puzzle level. Which makes that data anything but plain.
Wait, you mean “interpreting” in the “interpreted (computer) language” sense, and not in any more general layperson sense? Really?
A unicode text file is a series of intructions that tell you which character to render where on the screen. A potentially fairly complicated set of instructions, when you consider RTL languages, combining characters, context-dependent character form, and so on.
The Sokoban level I posted uses a very, very primitive subset of that language. Every character in the example represents exactly that character on the screen. The game runs in text mode, so the characters are stored directly in video memory. There is no data representation of the game state beyond what’s in video memory.
Maybe it helps if we consider not a puzzle level, but maybe a quest module in a game like Skyrim. Such a thing is basically a script.
I consider the actual scripting part of a Skyrim quest module to be code. Not the images. Not the text. Not the sound. And especially not map or the stats of the enemies or the general idea of the quest, although all of these things can be encoded in the script.
When someone says that they used assistance for coding I assume that they mean that they came with the game design and used assistance for turning it into code. When someone uses assistance for the game design or any of its subsets (level design, puzzle design, world design, narrative design, whatever) but writes the code themselves, I don’t expect them to say that they used assistance for coding. I do expect them to say that they used AI assistance in general.
Here is an interesting thought experiment for you. Imagine an animated movie where the director is an AI. The artists are all human, so the graphics are not AI-assisted. The script is written by a human, so the text is not AI-assisted. The sounds are all produced by humans, no AI there.
The humans don’t even need to be aware of the AI director, if that awareness taints their work in your opinion. The AI director can come along later and cut the movie together from previously created assets. The AI director makes the ultimate decision about what goes where, but creates nothing.
So, how would you handle AI disclosure for the movie? The AI director does all of the things that you ascribe to “code” in a game, but there is literally no code in a movie. Unless you count the codec used to encode the movie as a computer file.
