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 MyClass : MonoBehaviour
{
    public string myValue;
}

And you would like to create a property to encapsulate myValue without losing any data already assigned to instances of MyClass. You can achieve that by using this attribute:

using UnityEngine;
using UnityEngine.Serialization;

public class MyClass : MonoBehaviour
{
    [FormerlySerializedAs("myValue")]
    string m_MyValue;
    public string myValue
    {
        get { return m_MyValue; }
        set { m_MyValue = value; }
    }
}
