Struct ScreenFlash 

Source 
pub struct ScreenFlash {
    pub color: Color,
    pub intensity: f32,
    pub decay: f32,
}
Expand description

draws a fullscreen colored overlay each frame.

use for damage flashes, screen transitions, fades. set decay > 0.0 and the engine automatically reduces intensity over time via decay_screen_flash_system.

insert this as a resource; remove it when intensity reaches 0 if you don’t want it to linger.

§example

ⓘ
commands.insert_resource(ScreenFlash {
    color: Color::RED,
    intensity: 0.5,
    decay: 3.0,  // fades out in ~0.17 seconds
});

Fields§

§color: Color§intensity: f32

opacity: 0.0 = invisible, 1.0 = fully opaque.

§decay: f32

intensity units lost per second. 0.0 = persistent.
