Will generate a map with biomes based on a Whittaker diagram found here.
Run npm run example to generate a new map example . It will output the result to ./example-map.json and render it in the console as well.
You can update the ./index.js file to play a round a bit more with some settings.
Made as a small side project to learn a bit more about random map generation.
install npm install random-map-generator
import fs from 'fs';
import { Generator } from 'random-map-generator';
// any string; if null a random seed will be generated
const seed = null;
const height = 100;
const width = 100;
const worldMap = new Generator(width, height, seed);
// how many steppers to generate, which creates land mass
worldMap.setLandmassStepperCount(100);
// how many steps a stepper should take
worldMap.setLandmassStepperStep(150);
// how many rivers to generate (min, max)
worldMap.setRivers(1, 2);
// generate the map
await worldMap.generate();
// render the map to console.
mapGenerator.outputToConsole();
// output the map seed
console.log(chalk.green(`Seed: ${mapGenerator.seed}`));
// save the map to json
fs.writeFileSync('./map.json', JSON.stringify(mapGenerator.matrix));
The floodFil method will cause the maximum call stack to be exceeded if going much above 100x100 map.
I created a version which utilises a single while loop, but the map generator goes from about 0.5s generation time for a 100x100 map, to several seconds.
Suggestions welcome!
