Basics
Specifies the 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/float, 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
color
Type: Types/color
Default: Light has no color
Color of the light.
add_perspective
Type: Types/bool
Default: false
shift
Type: Types/vector
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}}
