About

Rust boids simulation using Reynolds model running with Bevy engine.

The following parameters can be updated while the simulation is running:

• turn factor: boids ability to turn fast
• visual range: radius (in px) of the circle in which boids can see
• protected range: radius (in px) of the circle in which boids wants to be alone
• centering factor (cohesion rule) : boids move toward the center of mass of their neighbors
• avoid factor (separation rule): boids move away from other boids that are in protected range
• matching factor (alignment rule): boids try to match the average velocity of boids located in its visual range
• Maximum boids velocity
• Minimum boids velocity
• bias: some boids are searching for food, and are not exactly following the flock

While all the parameters can be updated live, you can also press 'P' to pause/resume the simulation. Press 'Q' to leave.

How to launch

Using cargo (recommended)

Install bevy dependencies and then just launch:

cargo install boids_rs_bevy
boids_rs_bevy

Build manually

Firstly, install bevy dependencies

Then clone this repository and launch :

cargo run --release

Note: if you want to launch as dev, make sure to add the following feature to decrease compilation time :

cargo run --features bevy/dynamic_linking
