}

A single particle in the system

Fields

age: f32

Current age in seconds

lifespan: f32

Total lifespan in seconds

color: [f32; 4]

Current color (RGBA, 0.0-1.0)

scale: [f32; 2]

Current scale (width, height)

tex_coord_head: [f32; 2]

Texture coordinates for head cell

tex_coord_tail: [f32; 2]

Texture coordinates for tail cell (for ribbon particles)

position: [f32; 3]

World-space position

velocity: [f32; 3]

Velocity vector

Implementations

impl Particle

pub fn new(position: [f32; 3], velocity: [f32; 3], lifespan: f32) -> Self

Create a new particle with initial position, velocity, and lifespan

pub fn is_alive(&self) -> bool

Check if the particle is still alive

pub fn age_percent(&self) -> f32

Get the age as a percentage of lifespan (0.0 to 1.0)

pub fn update_physics(&mut self, dt: f32, force: [f32; 3], drag: f32)

Update particle physics

Arguments

• dt - Delta time in seconds
• force - Combined force vector (wind - gravity)
• drag - Drag coefficient (0.0 = no drag, 1.0 = full drag)
