💡 Light
Une entité Light représente une source d'éclairage.
info
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 😉.
Utilisation
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?
)

Profils de Lumière
Les profils lumineux sont des fichiers de textures qui décrivent la distribution d'une lumière à partir d'une source lumineuse en utilisant des données mesurées dans le monde réel.
tip
Veuillez consulter la documentation Unreal Engine Light Profile pour plus d'informations sur les profils de lumière!
Nanos World fournit 50 profils de lumière inclus dans le jeu de base que vous pouvez utiliser pour améliorer vos entités Light. Vous pouvez les définir en utilisant :SetTextureLightProfile() avec l'enum LightProfile.
