spatial_hash.py
Full Source
The complete implementation covers:
›`SpatialHash` class with bucket resolution tuning
›`Boid` class with vectorized NumPy rules
›Pygame render loop at 60fps
›Keyboard controls for live weight adjustment
See the `Swarm_tutorial/Swarm_Simulation/` folder in the Swarmsara repo for the full source.
Running It
python main.py
Controls:
›`S` / `A` / `C` — increase separation / alignment / cohesion weight
›`R` — reset to defaults
›`+` / `-` — add / remove boids
