SDL2 Particles

Rust plug and play library for creating customizable particles with SDL2 context

Preview

Example

Add crate to Cargo.toml and import everything at the beginning of your program:

use sdl2_particles::*;

Create a mutable particle state object and set its size (maximum number of particles):

let mut particles_state = ParticlesState::init(250);

Declare and customize ParticleType:

let emitting_type = ParticleTypeBuilder::new(16, 16, Duration::from_secs(2))
    .with_color(random_color)
    .with_effect(ParticleEffect::LinearMovement{velocity_x: random_velocity_x,velocity_y: -200.0})
    .with_effect(ParticleEffect::LinearRotation{angular_velocity:60.0})
    .with_effect(ParticleEffect::FadeOut{delay: Duration::from_secs_f32(1.0)})
    .build();

Then initialize sdl2 window and context as you would do normally and create a game loop. Inside you must update and render and spawn your particles

loop {
    particles_state.emit(5, &emitting_type, 400.0, 600.0);
    particles_state.update(dt);
    particles_state.render(&mut sdl_canvas);
}
