Either a table with the properties listed below or an array of tables with the below properties. Specifies a light source.

Mandatory properties

type

Type: Types/string

Default: "basic"

Either "basic" or "oriented". If the type is "oriented", the following properties are read additionally to the other properties:

• picture - Types/Sprite, mandatory
• rotation_shift - Types/RealOrientation, optional

intensity

Type: Types/float

Brightness of the light in the range [0, 1] where 0 is no light and 1 is the maximum light.

intensity = 0.5

size

Type: Types/float

The radius of the light in tiles. Note, that the light gets darker near the edges, so the effective size of the light seems to be smaller.

size = 15 -- big light source

Optional properties

source_orientation_offset

Type: Types/RealOrientation

Default: 0

add_perspective

Type: Types/bool

Default: false

shift

Type: Types/vector

color

Type: Types/Color

Default: Light has no color

Color of the light.

minimum_darkness

Type: Types/float

Default: 0

Example

The light of the orange state of the rail signal.

orange_light = {intensity = 0.2, size = 4, color={r=1, g=0.5}}

The front lights of the car:

light =
{
  {
    type = "oriented",
    minimum_darkness = 0.3,
    picture =
    {
      filename = "__core__/graphics/light-cone.png",
      priority = "extra-high",
      flags = { "light" },
      scale = 2,
      width = 200,
      height = 200
    },
    shift = {-0.6, -14},
    size = 2,
    intensity = 0.6,
    color = {r = 0.92, g = 0.77, b = 0.3}
  },
  {
    type = "oriented",
    minimum_darkness = 0.3,
    picture =
    {
      filename = "__core__/graphics/light-cone.png",
      priority = "extra-high",
      flags = { "light" },
      scale = 2,
      width = 200,
      height = 200
    },
    shift = {0.6, -14},
    size = 2,
    intensity = 0.6,
    color = {r = 0.92, g = 0.77, b = 0.3}
  }
}
