Reinforce the MonoBehaviour lifecycle with a summary task.
MonoBehaviour summary
In a class derived from MonoBehaviour, Unity calls three methods in order: Awake first, then Start, and then Update in every frame. Awake and Start run only once.
public class Oyuncu : MonoBehaviour
{
void Awake() { /* first */ }
void Start() { /* once */ }
void Update() { /* every frame */ }
}You can make your fields visible in the Inspector with public or [SerializeField].
Practice Lifecycle summary
In a class named Ozet, make a private int can field visible in the Inspector with [SerializeField]. In Awake, print "Oyun hazirlaniyor" and in Start, print "Can: 100" with Debug.Log, and in Update, increase the sayac variable by one every frame.
Starter code
using UnityEngine;
public class Ozet : MonoBehaviour
{
// 1) can adli private alani Inspector'da gorunur yap
// 2) Awake icinde "Oyun hazirlaniyor", Start icinde "Can: 100" yazdir
// 3) Update icinde sayaci her karede bir artsin
}Sample solution
using UnityEngine;
public class Ozet : MonoBehaviour
{
[SerializeField] private int can = 100;
int sayac;
void Awake()
{
Debug.Log("Oyun hazirlaniyor");
}
void Start()
{
Debug.Log("Can: 100");
}
void Update()
{
sayac++;
}
}Expected output
Oyun hazirlaniyor Can: 100
