Learn that post-processing applies effects to the frame.
What is post-processing?
Post-processing is the effect stage applied to the image after the frame of the game has been rendered. It only affects the final look without changing the objects in the scene. This way settings such as brightness, color and blur are done on the frame.
efektAdi = "Bloom";
efektGecerli = true;These effects artistically edit the final image the camera sees.
Working on the frame
Post-processing effects are applied in order on a single frame. Each effect takes the output of the previous one and produces a new result. This is why the order of effects changes the outcome.
islenmis = bloom(islenmis);
islenmis = vignette(islenmis);In the end, the processed frame is shown on the screen.
Practice Keep an effect record
In a class named EfektKaydi, define a string ad field with the value "Post-processing". In the Start method, print the text "Efekt: " joined with ad using Debug.Log.
Starter code
using UnityEngine;
public class EfektKaydi : MonoBehaviour
{
// string ad alanini "Post-processing" degeriyle tanimla
void Start()
{
// "Efekt: " metnini ad ile birlestirip yazdir
}
}Sample solution
using UnityEngine;
public class EfektKaydi : MonoBehaviour
{
string ad = "Post-processing";
void Start()
{
Debug.Log("Efekt: " + ad);
}
}Expected output
Efekt: Post-processing
