Building a roguelike game with Rot.js
Blog post from LogRocket
Roguelike games, known for their turn-based gameplay, randomly generated levels, and character permadeath, have a rich tradition in gaming, with Dungeons & Dragons being a notable example. Rot.js, a JavaScript library, simplifies the development of these games in a browser by offering tools for random number generation, pathfinding, field-of-view computation, and key binding. Inspired by "libtcod," Rot.js provides a user-friendly API for creating canvas-based displays and map generation, allowing developers to craft intricate game worlds with ease. It includes three map generators—Maze, Cellular, and Dungeon—each offering unique customization options. Additionally, Rot.js supports asynchronous game engines and pathfinding via Dijkstra's Algorithm, enhancing game interactivity and AI. The library's key mapping capabilities facilitate intuitive player controls, and its utility functions aid in number and string manipulation. A practical example of using Rot.js is a game called "Log the Rocket," where players navigate a randomly generated map to reach an exit, showcasing Rot.js's capabilities in creating dynamic and engaging roguelike experiences.
