This is a Boids simulation, written in Python3, with Pygame2 and NumPy.
To use: Save the pynboids_sp.py file (and nboids.png if you want the
icon, not required) and run via python. (Example: python3 pynboids.py)
Esc key to quit.
I've included several customizable settings near the top of the code.
You can adjust window size, fullscreen, fps, and how many boids to spawn,
as well as whether they avoid the screen edges or wrap to the other side,
change the background color, or turn the boids into fish! ;)
Minor updates to several files. New nboids_ss.py version is a linux-only
pseudo-screensaver that requires xprintidle be installed. BUT, due
to a possible memory leak, the screensaver must be started using run_ss.py.
New pynboids_sp.py version, implements a spatial partitioning grid to
improve efficiency of detecting other boids. Most efficient version so far!
Added pynboids2.py version, an update to the original pynboids, with numpy
array methods from pixelboids.py to improve efficiency. 2x more boids then b4.
Added pixelboids.py version, draws boids as pixels in surfarray that fades
as they move. Distance sorting & for-loop math replaced with numpy array math.
Uses a fading surfArray to create tails, pixelation makes them look animated.
I couldn't have gotten this far without the Pygame Discord channel:
CozyFractal, for help with the spatial partition grid & improving efficiency.
Mega_JC, Ghast, and bydariogamer, for answering various questions I had.
