Struct ScreenLight 

pub struct ScreenLight {
    pub x: f32,
    pub y: f32,
    pub radius: f32,
    pub color: Vec3,
    pub intensity: f32,
    pub shadows: bool,
}

A light in screen space, for the light map.

Pixels within radius of it are lit in its colour, falling off with distance; with shadows on, matter between the light and a pixel takes the light away, so figures are lit on the side that faces it and cast their shape across the floor behind them.

Fields

x: f32

Centre, in screen pixels from the top left.

y: f32

radius: f32

How far it reaches, in pixels.

color: Vec3

Linear RGB.

intensity: f32

1.0 lights its surroundings fully at its centre; 0.3 is a candle.

shadows: bool

Whether matter shadows it.
