• Player 1: arrows and right CTRL to fire
• Player 2: WSAD and left CTRL to fire
• Pause: ENTER

• Show targets of enemies: t

Each enemy may fire only one bullet in the same time. If bullet hits target, brick or stage border and explodes then enemy may fire next one. Enemies may have one of four different armour levels. Each level have a different colour. After bullet hit armour level decrease. If the armour level falls to zero, then enemy is destroyed.

If enemy blinks, each hit create new bonus item on a map.

• A:
  • target: closest player or eagle;
  • speed: normal:
  • behaviour: 80% to move towards the target, 20% to move in random direction,
  • constantly fires in movement direction
• B:
  • target: eagle;
  • speed: 1.3 * normal;
  • behaviour: 50% to move towards the target, 50% to move in random direction,
  • constantly fires in movement direction
• C:
  • target: eagle;
  • speed: normal;
  • behaviour: 50% to move towards the target, 50% to move in random direction,
  • constantly fires in movement direction
• D:
  • target: closest player or eagle;
  • speed: normal;
  • behaviour: 50% to move towards the target, 50% to move in random direction,

• make
• libsdl2-dev
• libsdl2-ttf-dev
• libsdl2-image-dev
• doxygen-gui - for docs generation (optional)
• doxygen - for docs generation (optional)

On Debian based systems you can run (apt can by replaced with apt-get or aptitude):

sudo apt install libsdl2-dev libsdl2-ttf-dev libsdl2-image-dev

• make
• sdl2
• sdl2_ttf
• sdl2_image

brew install sdl2 sdl2_ttf sdl2_image

In the project directory run:

make clean all

As a result build directory should be created. In build/bin there will be Tanks binary file with all necessary resources files.

The Tanks has to be run from bin directory otherwise you got black screen. Have fun.

cd build/bin && ./Tanks

In the project directory run:

make doc

• MinGW
• mingw32-base-bin
• mingw32-gcc-g++-bin
• MINGW_HOME environment variable pointing to MinGW directory (eg. C:\MinGW)
• MinGW bin directory added to Path environment variable (eg. C:\MinGW\bin)
• GitBash or any similar package providing cp and rm commands

In the project directory run GitBash and run:

mingw32-make.exe clean all

As a result build directory should be created. In build/bin there will be Tanks.exe binary file with all necessary resources files. Have fun.

cd build/bin && ./Tanks.exe
