Struct tahga::pursuit::boids::Boids

pub struct Boids {
    pub boids: Vec<Boid>,
    pub visual_range: f32,
    pub max_speed: f32,
    /* private fields */
}

A struct holding a list of all boids

Fields

boids: Vec<Boid>

The list of boids

visual_range: f32

The range at which a boid can see other boids

max_speed: f32

The max speed of this boid

Implementations

impl Boids

pub fn new() -> Self

Create a new instance of Boids, populated with default values and an empty list

Examples

use nannou::prelude::*;
use tahga::pursuit::boids::Boids;
let b = Boids::new();
assert_eq!(b.visual_range, 75.);
assert_eq!(b.max_speed, 15.);

pub fn new_boid(&self, position: Vec2, velocity: Vec2) -> Boid

Create a new Boid

This is just a wrapper around Boid::new(). It also sets the options using the current stored values.

Arguments

position - The position of the new Boid

velocity - The velocity of the new Boid

Examples

use nannou::prelude::*;
use tahga::pursuit::boids::Boids;
let b = Boids::new();
let nb = b.new_boid(vec2(0., 0.), vec2(10.,10.));
assert_eq!(nb.visual_range, 75.);
assert_eq!(nb.max_speed, 15.);

pub fn add_boid(&mut self, boid: Boid)

Add a Boid to the list

Arguments

boid - A Boid to add

Examples

use nannou::prelude::*;
use tahga::pursuit::boids::Boids;
let mut b = Boids::new();
let nb = b.new_boid(vec2(0., 0.), vec2(10.,10.));
b.add_boid(nb);
assert_eq!(b.boids[0].visual_range, 75.);
assert_eq!(b.boids[0].max_speed, 15.);

pub fn update(&mut self, app: &App)

Update all the boids in the list

Arguments

app - The nannou app opject
