Re: [Caml-list] ANN: Boulder Dash in OCaml

[Andreas Rossberg <rossberg@mpi-sws.org>]

Couldn’t let it rest, so I’m (already) announcing version 2 of it — now a much improved, practically feature-complete reimplementation of both Boulder Dash 1 & 2.

Version 2 was an excuse for me to mess around with the OCaml bindings to popular graphics engines, and as a result, it now comes with 3 backends to choose from:

1. the homely bare OCaml Graphics library (https://github.com/ocaml/graphics),
2. the TSDL binding to the SDL2 API (https://github.com/dbuenzli/tsdl),
3. the binding to the Raylib engine (https://github.com/tjammer/raylib-ocaml).

The list is in order of increasingly better user experience, for the price of a potentially harder build experience. In theory, all versions should run on Windows, Mac, and Linux, though I was too lazy to test all combinations, and I (or my opam) had trouble installing some of the dependencies on some of the systems.

Features:

* Faithful original physics, graphics, animations, sound, and music
* Authentic scrolling mechanics combined with dynamic resizing
* All 40 levels and 5 difficulties of Boulder Dash 1 & 2
* Pause-and-go mode for relaxed playing

Relative to the previous release, version 2 adds the following niceties:

* Support for SDL and Raylib engines, which allow all of the following
* Original sound effects and music
* Original level color schemes
* Full screen mode
* Faster graphics
* Dynamic graphics scaling adjustment
* Gamepad/joystick support as well as more precise keyboard controls
* Boulder Dash 2 levels and decoder

Almost looks like a real game now. One from the 80s anyways. :)

Enjoy,
/Andreas
