    pub life_state: LifeState,
    pub time_elapsed: Duration,
    pub config: ParticleConfig,
}

The struct representing a single particle

Fields

pos: Vec2

vel: Vec2

trail: VecDeque<Vec2>

Records a trail_length of previous positions of the Particle

life_state: LifeState

time_elapsed: Duration

Duration since initialization of this Particle

config: ParticleConfig

Implementations

impl Particle

pub fn new( pos: Vec2, vel: Vec2, trail_length: usize, life_time: Duration, color: (u8, u8, u8), ) -> Self

Create a new Particle

pub fn is_dead(&self) -> bool

Return true if Particle’s LifeState is Dead

pub fn reset(&mut self)

Reset Particle to its initial state

pub fn update(&mut self, duration: Duration, config: &FireworkConfig)

Update the Particle based on delta time

Arguments

• • duration - Duration since last update
