Struct GpuParticle 

pub struct GpuParticle {
    pub position: [f32; 3],
    pub velocity: [f32; 3],
    pub life: f32,
    pub color: [f32; 4],
    pub size: f32,
}

A single GPU-style particle with position, velocity, life, color and size.

Fields

position: [f32; 3]

World-space position [x, y, z].

velocity: [f32; 3]

World-space velocity [vx, vy, vz].

life: f32

Remaining lifetime in seconds. <= 0 means dead.

color: [f32; 4]

RGBA color [r, g, b, a] each in [0, 1].

size: f32

Billboard size in world units.

Implementations

impl GpuParticle

pub fn new( position: [f32; 3], velocity: [f32; 3], life: f32, color: [f32; 4], size: f32, ) -> Self

Create a new particle with the given attributes.

pub fn is_alive(&self) -> bool

Returns true if this particle is still alive.

Trait Implementations

impl Clone for GpuParticle

fn clone(&self) -> GpuParticle

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for GpuParticle

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for GpuParticle

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for GpuParticle

fn eq(&self, other: &GpuParticle) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
