Standalone version of xkcd 1608 "Hoverboard" game.

Screenshot

Why

I'm a big fan of xkcd by Randall Munroe, and now he has released an exploration game to celebrate his new book. The game is great as all his comics, however it unfortunately is only available on web, which implies:

  • You can't play offline
  • It's a pain to play with poor or intermittent connection
  • Inefficient web technologies waste your battery life and may produce noticeable lags
  • You are limited with fixed 740x700 visible area, which may take only a small part of available screen space, or, vice versa, not fit into the screen
  • You can't see the source
  • You can't improve it, for example implementing save/load or a minimap

So there's plenty of reasons to have a proper native application, and, given that Randall makes the art available under CC-by-NC license, I want to accomplish that.

Features

I consider this a feature-complete reimplementation - it provides the complete experience of the original hame and only lacks some hidden features like Gandalf mode. The project is now focused on optimization and extra features (such as game state saving).

Extra features compared to original:

  • Persistent state - when you leave the game, you location and picked coins are saved, so when you run the game again, you may continue your journey from the same point
  • Saved locations - you may save up to 10 locations and return to them with a single key press
  • Map - shows explored parts of the world and known coin locations

Controls

  • Arrow keys or WASD or HJKL - move character
  • Esc or Q - leave the game
  • Ctrl+0, Ctrl+1 ... Ctrl+9 - save player location
  • 0, 1 ... 9 - jump to corresponding saved location
  • Tab - toggle map

Building

Dependencies:

To install these on apt-using system sych as Debian or Ubuntu, run:

apt-get install cmake libsdl2-dev libsdl2-image-dev libsdl2-ttf-dev

The project also uses libSDL2pp, C++11 bindings library for SDL2. It's included into git repository as a submodule, so if you've obtained source through git, don't forget to run git submodule init && git submodule update.

To build and run the game without installation:

cmake .
make
./hoverboard

To install systemwide:

cmake -DCMAKE_INSTALL_PREFIX=/usr/local -DSYSTEMWIDE=ON
make
make install

To create self-contained directory for standalone package:

cmake -DCMAKE_INSTALL_PREFIX=./package -DSTANDALONE=ON
make
make install
