This repo includes some of the work I did looking at Minecraft stronghold generation last weekend. I wanted to see if strongholds were evenly distributed along the first ring, or if they were most likely to be generated in certain locations.
First, I needed to obtain a large list of strongholds. This was relatively easy, but I made it a lot more complicated than it needed to be. I found a cool repository called cubiomes (https://github.com/Cubitect/cubiomes) that fit the job well.
However, I wanted to try doing data analysis in rust (sue me), so I tried making some bindings for it. I spent around 3 hours messing with bindgen before I finally gave up and wrote some code in C that exported a list of stronghold locations to a text file. Its a pretty big file, so I didn't include it here but you can generate it using lister.c.
Now that I had my data (I started with 1 millionish samples), it was time to mess around a bit. To make sure I didn't screw anything up, I made a 200x200 array for use as a kind of frequency map (yes, I got a stack overflow before I put it in a box, shut up). I outputted it into a file (and learned about > vs >> in bash) and came up with map.txt (https://github.com/Dworv/stronghold-analysis/blob/main/map.txt).
Next, I made a histogram for the frequency map using Plotters (https://github.com/plotters-rs/plotters). That went pretty smoothly, Plotters is very nice.
Finally, I wanted something out of the project that looked cool. I decided to make a map of the frequencies from above to visualize it. I need to hijack the SVGBackend from Plotters (they probably have an easy way to do this, but I'm too lazy to figure it out). Here it is.

Weirdly, there seems to be some kind of grid going on there. I wonder if that is a real feature of the generation, or simply an issue with cubiomes. Maybe I'll come back to this someday.
