SerializeField and public

Learn to use SerializeField and public for Inspector-visible fields.

Public fields

Fields declared as public appear in the Inspector window and can be edited there. This way you can change the value without touching the code.

public class Dusman : MonoBehaviour
{
    public int can = 100;
    public float hiz = 5f;
}

These fields are reachable both from code and from the Inspector.

[SerializeField]

private fields are not visible in the Inspector by default. When you add the [SerializeField] attribute, the field stays private but becomes visible in the Inspector.

public class Dusman : MonoBehaviour
{
    [SerializeField] private float hiz = 5f;
}

This way the value can be set from the Inspector while the field stays hidden in code.

Exercise Inspector fields

In a class named Dusman, declare a public int can = 100; field. Then make a private float hiz field visible in the Inspector with [SerializeField], and in Start print "Hazir" with Debug.Log.

Show example solution

using UnityEngine;

public class Dusman : MonoBehaviour
{
    public int can = 100;
    [SerializeField] private float hiz = 5f;

    void Start()
    {
        Debug.Log("Hazir");
    }
}

Test yourself

What happens to a field declared as public in a class?
- It appears in the Inspector and its value can be edited there
- It causes a compile error
- It automatically becomes static
- It is reachable only from code and does not appear in the Inspector
