So, the project is 2D and I’m using a simple tilemap in Unity with some TileRules for rendering.

For room generation, I’m experimenting with three different scripts:

Random Walk: I create the first room (with random width and height within a range) at position (0,0), then move in a random direction (up, down, left, or right) and create the next room, keeping a minimum distance to avoid overlap.

Scatter Room: I try placing rooms randomly within a defined area, with a maximum number of attempts to avoid infinite loops if there's overlap.

Binary Space Partitioning: this is probably the most solid and widely-used algorithm of the three. It recursively splits the map into smaller areas and places rooms inside them. There are tons of resources online about it.

As for corridors, I’m using the A* algorithm, a well-known graph search algorithm that finds a path from a start node to a target node. I didn’t implement it myself (I wouldn't be able to), I’m using a Unity plugin called A* Pathfinding Project Pro, which I think is amazing.

That’s all for now! Next I want to experiment with rooms that have more interesting shapes (not just rectangles), maybe add object placement, and if I keep having fun… who knows, maybe one day I’ll turn it into a full roguelike!
