Ananas aus Caracas: a sample game built using rot.js

Welcome to this tutorial! We are going to create a very simple roguelike game, playable in any modern browser. To achieve this, our language of choice would be JavaScript; to simplify our work, we are going to use the rot.js toolkit.

Requirements

  • Basic JavaScript knowledge
  • Modern web browser (Firefox, Chrome, Opera, Safari, IE9+)

Game setting

The tutorial consists of three chapters, which gradually add more and more functionality. The game itself is pretty simple: motivated by video, a player needs to find an ananas hidden within several boxes in an underground dungeon. It is necessary to find the ananas before Pedro (the ananas owner) finds and punishes you for sneaking into his warehouse.
