Module particles 

Particle effects for egui.

Three effects: Snow, ported from egui-snow (MIT, Copyright (c) 2025 LaVashikk, v0.36.0); Light, soft radial glow motes and rising embers; and Lightning, a jagged bolt with a full-area flash. All keep their per-frame state in egui’s temporary data storage and paint on an egui layer, so they never disturb the host layout. Randomness uses an internal PRNG instead of rand, so the crate gains no dependency.

Each effect ships a settings struct (SnowSettings, LightSettings, LightningSettings) that collects the public knobs and draws a themed settings window through show_window, or just the controls through body_ui for a host-provided container; from_settings turns the knobs into a configured effect.

use egui::Ui;
use egui_elements::widgets::particles::{
   Light, LightSettings, Lightning, LightningSettings, Snow, SnowSettings,
};

fn particles(
   ui: &mut Ui,
   snow: &mut SnowSettings,
   light: &mut LightSettings,
   lightning: &mut LightningSettings,
) {
   snow.show_window(ui.ctx());
   light.show_window(ui.ctx());
   lightning.show_window(ui.ctx());
   if snow.active {
      Snow::from_settings("snow", snow).show(ui);
   }
   if light.active {
      Light::from_settings("light", light).show(ui);
   }
   if lightning.active {
      Lightning::from_settings(LightningSettings::STRIKE_ID, lightning).show(ui);
   }
}
