Flocking-Behavior-Simulation

Boids Algorithm Flocking simulation on Unreal Engine 4

Setup

• Right click on 'boidsAlgorithm.uproject' and generate VS project files
• Open project in UE4 and accept build requests
• Launch project

Simulation

Settings to simulate flocking behavior:

• AreaExtent (4000 * 4000 * 400): Size of simulation volume
• Boids (600) - Number of boid instances to use
• Max Velocity (2000) - Maximum velocity for boids
• Cohesion Distance (1300) - Min separation for cohesion. Smaller value will result in smaller flocks.
• Separation Distance (200) - Min separation for boids to avoid others.
• Alignment Distance (300) - Min separation for boids to align with others
• Cohesion Factor (500) - Weight factor for cohesion
• Separation Factor (110) - Weight factor for separation.
• Alignment Factor (80) - Weight factor for alignment
• Avoidance Factor (1000)
• Avoidance Distance (400)

Settings can be modified in BP_Director. '2' to speed up sim
