Struct ParticleSystem 

pub struct ParticleSystem { /* private fields */ }

Particle system for visual effects.

Implementations

impl ParticleSystem

pub fn new(pool_size: usize) -> Self

Creates a new particle system with the given pool size.

pub fn spawn( &mut self, x: f32, y: f32, count: usize, speed: f32, lifetime: f32, size: f32, color: u32, )

Spawns particles at the given position.

Arguments

• x - X position
• y - Y position
• count - Number of particles to spawn
• speed - Base speed of particles
• lifetime - Base lifetime in seconds
• size - Base size (radius)
• color - Color as 0xRRGGBB
