This is a Boids Simulation, written in Python with Pygame.

Overview

PyNBoids

A Python Boids Simulation

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! ;)

Update (5/20/21):

New pynboids_sp.py version, implements a spatial partitioning grid to improve efficiency of detecting other boids. Most efficient version so far!

Update (5/16/21):

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.

Update (5/14/21):

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.

Special Thanks: (Let me know if I forgot anyone.)

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.

How would I make them follow the mouse?

Hi :)

I would love to borrow your code to use in my program that I write for learning purposes only. There, stuff is following the mouse cursor on screen.
You implementation of boids looks very nice and seems also very performant. Now, your code isn't the easiest to read. Much math. Very complex. Variables have names like: "tAvejAng". What's that? Time-average-junction-angle? xD Edit: Well I know have "targetAverage_j_Angle" and that basically represents my understanding of your code.

I like the new stuff I learn from your code: self.boidSize = 22 if isFish else 17 and if (neighborCount := len(neighborBoids)) > 1: I didn't know about that.. :)

I generally know how to get and use the mousecursor postion and speed. The only issue is that it seems like the movement is all random, that there is no destination I could hijack. The destination is some ephemeral "where the most boids are", I guess. Maybe... it's so hard to read xD

Can you give me a hint where to start?

I hope you'll see this in due time. But if not, thenn I have to figure it out. Maybe I start by changing variable names. Thank you

Improved Boid class to be much more importable. Several values need to be passed to class, a few are optional. The example_scene.py file demos importing Boids as Fish, spawning separate groups in tinted layers for fake depth effect. This release was re-published, to put my delta-time implementation back to the correct method, and to update example.

r1(Apr 4, 2021)

Code works pretty good now. Marking a release to save current state. This first release is basically like a rough screensaver, at least when in fullscreen mode. Just a simulation to watch. Although Boids should be able to be imported and used in other projects, not all boid-settings are passable to the class/functions yet, like color or speed. I'll add more in a future update.
