FormerlySerializedAsAttribute

Description

Use this attribute to rename a field without losing its serialized value.

Suppose you have a class like this:

using UnityEngine;

public class MyMonster : MonoBehaviour
{
    public int hitpoints;
}

And you would now like to rename this field. You can achieve that by using this attribute:

using UnityEngine;
using UnityEngine.Serialization;

public class MyMonster : MonoBehaviour
{
    [FormerlySerializedAs("hitpoints")]
    public int health;
}

Unity serializes public variables by default. To serialize private variables, use the SerializeField attribute. For more information, see the Script Serialization documentation.
