Steering behaviours

There are three total sketches:

• Flocking behaviour
• Wandering, pursuing and evading behaviour
• Path following behaviour

How to run locally

• Clone the repository
• Open the index.html files of flocking behaviour, wanderer, pursuer and follower, and path following in Mozilla Firefox.

Flocking behaviour

The flocking behaviour is a combination of three behaviours:

• Alignment: Boids try to align their velocity with the average velocity of their neighbours
• Cohesion: Boids try to move towards the average position of their neighbours
• Separation: Boids try to avoid colliding with their neighbours

Wandering, pursuing and evading behaviour

• The follower will move towards the mouse and evade the pursuer
• The wanderer will wander and evade the follower
• The pursuer will pursue the wanderer

Path following behaviour

The boid will target a sequence of points and move towards them. When it reaches a point, it will move towards the next point in the sequence. Thus, path following is acheived.

Boids

Boids are the triangular creatures moving around the screen. They can do certain behaviours like:

• Wander around the screen
• Pursue another boid (predict where the target boid will be and move towards that point)
• Evade another boid (predict where the target boid will be and move away from that point)
• Flock with other boids (align, cohesion and separation)
• Seek a target (move towards a point)
• Arrive at a target (move towards a point and slow down as it gets closer)
• Follow a path
