rgehan/2d-world-generator

This is a basic 2D world generator, implemented in TypeScript. I had the idea for this after playing MoonQuest.

A live demo is available here.

It features:

• Height map generation
• Cave generation
• Ores generation
• Trees generation
• Water particles simulation

Setup

git clone [e-mail]:rgehan/2d-world-generator.git

cd 2d-world-generator/

yarn

Running the generator

yarn dev

Configuration

Map Generation

It takes a few parameters, allowing to generate very different kind of maps:

• size, used to determine how wide the map is in term of blocks. The map is 2^size blocks wide.
• level, the base ground level, 0 is the lowest, while 1 is the highest
• roughness, how rough the map is. 0 will produce a flat map, while 1 would produce a very rocky map
• mapHeight, how high the map is in term of blocks. It's just used when sampling the heightmap function.

Ore Generation

It takes an array of "steps". A step has a few parameters:

• blockId, which kind of block is generated by that step
• size, the size of the ore veins (used to scale a Perlin noise function)
• amount, the amount of ore in a given vein (used as a threshold for the Perlin noise function)

Cave Generation

It takes a few parameters; they determine how many and how long the caves are:

• count, the initial number of caves
• forkCapacity, the number of times a given tunnel can split into two tunnels

Liquid Generation

Determine the quantity of liquids generated and how good it looks:

• amount, the quantity of water generated
• iterations, how long the simulations run until we consider all liquid particles to have settled.

Tree Generation

• proba, the probability a given grass tile will yield a tree.
