About

A procgen experiment made during the 7DRL challenge 2023.

I spent way too much time on world and character generation and setting up the code architecture so there is no actual gameplay.

The idea was to make a roguelike combining classic roguelike concepts with colony sim gameplay (as in Rimworld, Norland) and grand strategy elements(Crusader Kings)

The player would control a royal family and has to manage a small kingdom.

World Slice Visualizer

Although the world appears to be 2D, it is actually a 3D terrain mesh rendered with an orthographic camera. It is regenerated whenever the viewport size or camera position changes.

The world slice visualizer samples a low-resolution dataset from the world data when zooming out very far. This allows for very large world sizes that can always be rendered without performance impact.

Menu System

I implemented an old school keyboard shortcut system for the ui elements.

Family Generator

During the jam I added a raw version of a family generator where the visual appearance and the stats of the parents would be inherited to younger generations.

The names for the generator were provided by chat-gpt.

World Generation & Biomes

The world is generated with multiple layers of Perlin Noise - for each cell humidity and temperature values are generated which then define the biome of the cell.

I experimented with several visual styles e.g. for the elevation lines.

Day/Night Cycle

To visualize the day/night cycle, I used a similar approach as in Rimworld, with shadow casting volumes for buildings

Wind Visualization

The wind direction for each cell visualized with arrows via a shader

Terraform Brush

With weird looking attempts on drawing smileys onto the terrain..

#7drl - day 3.5 - rewrote the rendering part - now supports all aspect ratios (was locked to 1:1 before) - did some stress testing on world sizes🤓

mapsize = 512 * 16 = 8.192 x 8.192 = 67.108.864 cells = 57 Seconds generation time pic.twitter.com/WkB0c3M9gj
