Rust plug and play library for creating customizable particles with SDL2 context
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); }More code and previews in examples/ folder
