Terrain Procedural General Experiments

This is a repository of experimental projects to procedurally generate terrain.

/Terrain

This is the most involved one, featuring voronoi and hexagonal heightmaps, wind and precipitation, river flux generation, and biomes based on the Holdridge model.

More detail in /terrain

/Water

A sprite-based erosion mechanism based heavily on a C++ example series and modified heavily. Not fast enough (and may still have bugs).

/voronoi-example

An initial project working with Voronoi grids and trying to build a definition file for TypeScript.

Uses the Javascript-Voronoi library and Phaser 3 polygons:

• A handwritten Typescript definition file, the hardest part: see it here
• Turns out it's super important to setOrigin(0,0) when you're drawing polygons

Running the Project

This project has a number of things built-in:

• eslint: a mix of recommended and reasonable rules, autofix is on by default in vscode via settings
• typescript: 3.8.3+
• editorconfig because vscode will autofix to standard stuff if you have the extension
• wallaby (Ctrl+R, R) for realtime test runner
• jest for tests
• phaser as the base engine

Top Level Commands

There are only two top-level commands at the moment:

• npm test - (only /terrain tests are active right now for wallaby)
• npm run lint

Example Projects

The commands are the same in each project folder:

1. cd voronoi-example
2. npm install
3. npm run start
