In this demo, we want to implement a basic day/night cycle. To do that, we will attach this script to the Direct Light object:
using UnityEngine;public class DayNightCycle : MonoBehaviour { public event System.EventHandler OnChanged; public float dayDuration = 10.0f; public bool isNight { get; private set; } private Color dayColor; private Light lightComponent; void Start() { lightComponent = GetComponent<Light>(); dayColor = lightComponent.color; } void Update() { Color nightColor = Color.white * 0.1f; float lightIntensity = 0.5f + Mathf.Sin(Time.time * 2.0f * Mathf.PI / dayDuration) / 2.0f; if (isNight != (lightIntensity < 0.3)) { isNight = !isNight; if (OnChanged != null) OnChanged(this, System.EventArgs.Empty); ...
