Clone

Clone the repository with the recurse-submodules option to clone the libraries repositories as well:

git clone --recurse-submodules https://github.com/lilianmallardeau/Homemade-Pacman.git

Then move to the cloned folder.

Build and run

mkdir build
cd build
cmake ..
make
cd ..
./build/Homemade_Pacman levels/level0

To run, the current working directory MUST be the root folder of the repository, because the program has to load the shaders files in the src/shaders/ folder and the texture in the assets/ folder.

Changing the game options

Some game options can be changed in the src/parameters.h header file. Although their name is already kind of explicit, here is a brief description of each of them:

Parameter	Description
FULLSCREEN	1 to enable fullscreen, 0 otherwise
SCALE	Initial size of each map unit, in pixels. Ignored if FULSCREEN is set to 1.
PACMAN_SPEED	Pacman movement at each frame, as a float1
GHOSTS_SPEED	Ghosts movement at each frame, as a float1
GHOSTS_NUMBER	Number of ghosts
MIN_GHOST_INIT_DISTANCE	Minimum distance between Pacman and the generated ghosts
GHOSTS_ANIMATION_SPEED	Delay in sec. between each sprite change for the ghosts
PACMAN_ANIMATION_SPEED	Delay in sec. between each sprite change for Pacman
BACKGROUND_COLOR	RGB background color
WALLS_COLOR	RGB walls color
TUNNEL_COLOR	RGB tunnels color
PELLETS_COLOR	RGB pellets color

TODOs

• Make the texture and the shader for MovableEntities static to avoid creating one for each entity
• Use smart pointers
• Use delta time instead of render loop to update the movement of the entities, to make the speed of the game independent of the system

Footnotes

1. The size of each map square is 1, ie. a speed of 1 will make pacman or the ghosts move of 1 square at each frame update (which is pretty fast 😅) ↩ ↩²
