Procedural Generation of 2D Tile Maps in Games

Introduction

Procedural content generation allows game developers to create diverse, replayable environments without manually designing each level. In this tutorial, we’ll cover a step-by-step method for generating a cave-like 2D map using cellular automata and show how to integrate the result into your engine of choice.

We’ll touch on:

  • Representing your map in code
  • Seeding and smoothing with CA
  • Ensuring connectivity
  • Rendering
