What worldGen is

worldGen is a free, open-source procedural map generator that builds 2D worlds from an integer seed. It can generate continents, oceans, rivers, forests, swamps, beaches, cliffs, settlements, and roads. Terrain begins with multifractal noise and is shaped through simulated raindrop erosion; its climate model accounts for rain shadows across mountain ranges. Elevation, moisture, and temperature produce thirteen biomes, and reusing a seed yields the same world. An interactive viewer supports panning, zooming, tile details, step-by-step visualization of generation, and screenshot export. The program can also export a world blob as a .bin file. Display and generation parameters can be adjusted in config.toml, with additional settings in world/config.go. worldGen is a Go desktop application using Ebiten and requires Go 1.21 or later and a desktop with OpenGL support. It runs on Linux, macOS, and Windows, and the repository specifies the MIT license. Its roadmap lists detailed urban layouts, more plant and biome variety, waterfalls, cliffs, and artificial life as future work.

Who it suits

worldGen suits people who want repeatable, seed-based 2D world generation and an interactive way to inspect maps. It requires Go 1.21 or later and desktop OpenGL support.

What it does well

Same integer seed produces the same world.
Generates thirteen biomes from environmental factors.
Viewer offers tile details and step-by-step generation.
Exports screenshots and .bin world blobs.
Free and open source under MIT.

What to know first

Requires Go 1.21 or later.
Requires desktop OpenGL support.
Detailed urban layouts remain roadmap work.
Additional plant and biome variety remains roadmap work.

Getting started

Open the project at https://github.com/paraglider0815/worldGen.
Use a desktop running Linux, macOS, or Windows with OpenGL support.
Install Go 1.21 or later.
Adjust display and generation parameters in config.toml or world/config.go.
Run the application, choose an integer seed, and inspect or export the generated world.

Verdict

worldGen offers reproducible map generation, a viewer for inspecting the process, and both screenshot and .bin exports. Its requirements include Go 1.21 or later and a desktop with OpenGL support.
