Order of programs, important since later programs reuse code from previous ones:
draw_circle.py
keyboard_events.py
draw_surface.py
player.py
user_input.py
enemies.py
sprite_images.py
background_images.py
game_speed.py
sound_effects.py
All programs should be run from the project root.
Example: cd <this project> ; python3 src/<program name>.py
.
