use bevy::prelude::*;
use bevy_particle_systems::ParticleSystemPlugin;
fn main() {

.add_systems(Startup, spawn_particle_system)
.run();
}
fn spawn_particle_system() { /* ... */ }
- Spawn a particle system whenever necessary.
use bevy::prelude::*;
use bevy_particle_systems::*;
fn spawn_particle_system(mut commands: Commands, asset_server: Res<AssetServer>) {
commands
// Add the bundle specifying the particle system itself.
.spawn(ParticleSystemBundle {
particle_system: ParticleSystem {
max_particles: 10_000,
texture: ParticleTexture::Sprite(asset_server.load("my_particle.png")),
spawn_rate_per_second: 25.0.into(),
initial_speed: JitteredValue::jittered(3.0, -1.0..1.0),
lifetime: JitteredValue::jittered(8.0, -2.0..2.0),

ColorPoint::new(Color::WHITE, 0.0),
ColorPoint::new(Color::srgba(0.0, 0.0, 1.0, 0.0), 1.0),
])),
looping: true,
system_duration_seconds: 10.0,
..ParticleSystem::default()
},
