Learn Directional, Point, Spot and Area light types.
Four light types
There are four light types in Unity scenes: Directional, Point, Spot and Area. A Spot light spreads in a cone like a flashlight; a Point light reaches in all directions from a single point like a candle. The light type is decided by the type property of the Light component.
isik.type = LightType.Spot;
isik.type = LightType.Point;In the examples below, the isik variable represents a Light component.
The character of each type
A Directional light is like the sun; its position does not matter, only its direction, and it sends parallel rays to every object. An Area light gives soft light from a rectangular surface. Choosing the right type for the need of the scene directly affects how it looks.
isik.type = LightType.Directional;
isik.type = LightType.Area;Each type exists for a different lighting purpose.
Practice Record the light type
In a class named IsikTanimi, define a string tur field with the value "Spot". In the Start method, print the text "Secilen tur: " joined with the tur variable using Debug.Log.
Starter code
using UnityEngine;
public class IsikTanimi : MonoBehaviour
{
// string tur alanini "Spot" degeriyle tanimla
void Start()
{
// "Secilen tur: " metnini tur degiskeniyle birlestirip yazdir
}
}Sample solution
using UnityEngine;
public class IsikTanimi : MonoBehaviour
{
string tur = "Spot";
void Start()
{
Debug.Log("Secilen tur: " + tur);
}
}Expected output
Secilen tur: Spot
