Struct ParticleSystem

pub struct ParticleSystem {
    pub transform: Transform2D,
    pub alive: bool,
    /* private fields */
}

A ParticleSystem deals with the emission, and creation of Particles.

Fields

transform: Transform2D

The Transform2D of the ParticleSystem.

alive: bool

A ParticleSystem needs to be alive to emit and update Particles.

Implementations

impl ParticleSystem

pub fn new_from_emission(emission: ParticleProps) -> Self

Create a new ParticleSystem using a ParticleProps for the emission.

pub fn new_from_emission_and_position( emission: ParticleProps, pos_x: f32, pos_y: f32, ) -> Self

Create a new ParticleSystem using a ParticleProps for the emission, and X and Y components for its position.

pub fn toggle_alive(&mut self)

Toggle the alive field of the ParticleSystem.

pub fn emit(&mut self)

Emit a single Particle, according to the defined ParticleProps for emission.

pub fn emit_many(&mut self, count: u32)

Emit multiple Particles, according to the defined ParticleProps for emission.
