💡 Light

A Light represents a Lighting source.

💂Authority
This class can be spawned on both 🟧 Client and 🟦 Server (if you spawn it on client, it won't be synchronized with other players).
👪Inheritance
This class shares methods and events from Base Entity Base Actor .

🎒 Examples

local my_light = Light(
Vector(-152, 245, 115),
Rotator(0, 90, 90), -- Pertinent uniquement pour les types d'éclairage Rect et Spot
Color(1, 0, 0), -- Teinte rouge
LightType.Point, -- Type de lumière "Point"
100, -- Intensité
250, -- Rayon d'atténuation
44, -- Angle du cône (ne concerne que le type de lumière Spot)
0, -- Angle du cône intérieur en pourcentage (ne concerne que le type de lumière Spot)
5000, -- Distance maximale d'affichage (bon pour la performance - 0 pour une distance infinie)
true, -- Utilisation ou non de l'affaiblissement de la distance au carré inverse basé sur la physique, où le rayon d'atténuation limite uniquement la contribution de la lumière. (Spot and Point types only)
true, -- Projeter des ombres ?
true -- Activé?
)

🛠 Constructors

Default Constructor

boolean cast_shadowstrue
boolean visibletrue
tip

Nanos World met à disposition 3 types de lumières : Spot, Point et Rect. Toutes les entités Light sont dynamiques, et donc très coûteuses! Gardez cela à l'esprit avant de faire apparaître 1000 lumières 😉.

💡 Light Profiles

Light Profiles are texture files which describes a light's distribution from a light source using real world measured data.

tip

Please check Unreal Engine Light Profile documentation for more information about Light Profiles!

nanos world provides 50 Light Profiles included in the base game which you can use to enhance your Lights. You can set them using :SetTextureLightProfile() with the enum LightProfile.
