Just another tower defense game which is badly designed, implemented and by all means is a waste of time, except that it is made for fun, learning and trying out new (to me) technologies, concepts and tricks.

The game is built on top of a custom C engine and all the logic and the actual game code is written in Python.

Try it out, fork it, hack it, and if you enjoy any part of it, let me know! :)

The C engine has to be compiled, and there is a number of tools and libraries needed:

• Python 3 (version 3.6.5✔)
• C compiler with C99 standard support
• tup build tool
• pkg-config (for Linux/OSX library discover)
• SDL2 development library (version 2.0.8✔)

Python3 venv module is used to create a bottled virtual environment to avoid messing the global one with project-specific packages.

python3 -m venv .env

By "activating" it, a number of shell variables will be overridden such a way that the local Python interpreter will be used and not the system one.

On Linux/OSX if using Bash:

source .env/bin/activate

On Windows in CMD/PowerShell

.env\Scripts\activate

Install the build-environment packages:

pip install -r requirements.txt

NOTE: these packages are required by build scripts.

Install the game runtime packages into engine's directory:

pip install -t core/beer/python/site-packages requirements.txt

NOTE: these packages are available to game's Python runtime for import, add there anything you'd need.

First, run the configure.py script which will attempt to find the compiler, libraries and whatever is needed and generate build rules:

On Linux/OSX:

python configure.py

On Windows you have to specify explicitly the paths to development headers and libraries using command-line options, for example:

python configure.py --sdl-incpath=C:\SDKs\SDL2-2.0.8\include --sdl-libpath=C:\SDKs\SDL2-2.0.8\lib\x64 --python-incpath=C:\Python36\include --python-libpath=C:\Python36\libs

For additional options and their meanings, check

python configure.py --help

The build command is the simplest one, assuming you have tup in system PATH:

tup

On successful build, you will have the game executable placed in core/, however, it may be necessary to specify also the library paths before runnning it, otherwise the loader won't be able to resolve missing DLLs:

Linux/OSX example:

LD_LIBRARY_PATH=core/beer core/defense-x86_64

Windows example:

set PATH=%PATH%;core/beer;C:\SDKs\SDL2-2.0.8\lib\x64;C:\Python36
core/defense-amd64.exe

NOTE: On Windows you can also copy-paste the required DLLs right into the directory where the executable is located.
