In Unity, [SerializeField] attribute is used to make the private variables accessible within the Unity editor without making them public. It helps maintain encapsulation A way to restrict the direct access to some components of the objects. Given below is a detailed explanation on using [SerializeField]. Line 1: It uses the [SerializeField] attribute before declaring a private variable.

In this article, I will explain everything you need to know about the SerializeField attribute in Unity. You will understand what types of fields are serializable. You will feel comfortable deciding when and where to use it in your code. You will also learn about [[System. If you understand what Serialization means, understanding SerializeField is easy. Unity wants to draw all the fields in the class in the Inspector. When you serialize the field, Unity has a copy on the disk that it can use to draw the field in the Inspector. When you change the value in the Inspector, you are changing the serialized object. Therefore, you must use SerializeField to enable Unity to draw an editable field in the Inspector. I will explain how Serialization impacts your project. Then, I will give an example of a serialized field, an implicitly serialized field, and a non-serialized field to illustrate how they work differently…. Other tutorials skip this topic.

As you work with Unity Editor, you use the Inspector window pretty frequently. But I believe most of us spend most of our time with Inspector window to tweak our GameObject s and their values. For programmers, in Unity lessons, we learned that a public attribute would show up in the Inspector window. However, making an attribute public is not always healthy for your code…. So first off, let me explain why public attributes are one of the potential risks for your project. They can be accessed from nearly anywhere outside your class, so they encourage two bad things: coupling code and complexity. This means, in short, that you will have to look at more than one place to find the source of an error, and as a result, the development process of the game is slowed down. But I cannot deny that editing a value in the Inspector window rather is easier, more designer-friendly and less time-consuming than in a code file. I asked this matter when I was an intern student, and one of my seniors told me to use [SerializeField] , and hurray, my private variables show up nicely in the Inspector windows. In later stage of my career, I figured out that this magical tag is not anything magical at all.
