A simple visualization of flocking behavior with boids.
Three rules govern how each boid moves.
- Separation: each boid will try to move away from other boids if they get too close.
- Alignment: each boid will try to steer in the average direction of neighboring boids.
- Cohesion: each boid will try to move towards the average location of neighboring boids.
TICK: Update frequency
TURN_INCREMENT: How many radians a boid can turn in one tick
NUM_BOIDS: Number of boids
BOID_RADIUS: Radius where boid can detect other boids
SEPARATION_BOID_RADIUS: Radius where boid will try to move away from other boids (personal space!)
W_COHESION: Cohesion weight
W_SEPARATION: Separation weight
W_ALIGNMENT: Alignment weight
DRAW_RADIUS: Whether to draw BOID_RADIUS and SEPARATION_BOID_RADIUS
DRAW_VECTOR: Whether to draw the vectors for the three rules
Requires SDL2 for graphics. I included all the necessary files along with the .exe to avoid the hassle of installing SDL.
