Falling-block object-oriented Fortran game, resizable playfield

BlockTran

Text/console falling-block tetromino game written in object-oriented Fortran 2008.

• user-configurable playfield size
• Logs pieces played to blocktran.log so you can recreate memorable games.
• uniform random game piece generation.
• clean, object-oriented Fortran 2008 syntax
• Curses (Ncurses, PDcurses) used for display, called directly from Fortran code.

Build

BlockTran works on Mac, Linux, native Windows, Cygwin, Windows Subsystem for Linux. Requires a Fortran compiler and CMake. Known to work with GCC Gfortran and Intel oneAPI (Classic or LLVM).

cmake -B build
cmake --build build

or using Fortran FPM:

fpm build
fpm run

The main executable file is build/blocktran. You can copy this file to your Desktop or wherever you like.

Linux / macOS

Ncurses is required. Alternatively, PDCurses + X11 development libraries are required for building on Linux.

Install X11 on Linux:

dnf install libX11-devel libXt-devel libXaw-devel ncurses-devel
# or
apt install libmxu-dev libxpm-dev libxt-dev libxaw7-dev libx11-dev

on macOS:

brew install libxt libxaw libx11

Play

difficulty level

adjust cadence of falling blocks with -d option, including decimal point:

blocktran -d 1.2

Higher number increase difficulty. Must include decimal point.

Playfield size

specify width and height of the playfield with -s option:

blocktran -s 20 15

play against computer

The computer player is rudimentary.

blocktran -p 2

debug mode

Debug logging is enabled by:

blocktran --debug

Controls

Other "secret" cheat keys exist! You can also use arrow keys.

Key	Effect
W	Rotate piece
A/D	Left and right respectively
S	Move down faster
Q or Esc	Exit the game

Notes

Block distribution is uniformly random as confirmed by:

./blockrand

blocktran's Issues

add topics

I suggest adding the topics game, games so that the repo will appear if someone searches language:fortran topic:game

auto-PDCurses CI debug

In "develop" branch, system NCurses worked on laptop for Windows and Linux for GCC, but fails on CI when using system NCurses.
Perhaps try on local Mac. Add logging to CI to diagnose failure.

Consider putting PDCurses autobuild in CI.
