Serialize unity

Serialization is the automatic process of transforming serialize unity structures or object states into a format that Unity can store and reconstruct later.

Some of the built-in features of Unity automatically use serialization. These are outlined below. See the documentation on Script Serialization for further information. If you use properties in your script, any of the property getters and setters are never called when you view or change values in the Inspector windows as Unity serializes the Inspector window fields directly. When you change and save a script, Unity reloads all the currently loaded script data. It first stores all serializable variables in all loaded scripts, and after loading the scripts restores them.

Serialization is the automatic process of transforming data structures or GameObject states into a format that Unity can store and reconstruct later. How you organize data in your Unity project affects how Unity serializes that data, which can have a significant impact on the performance of your project. This page outlines serialization in Unity and how to optimize your project for it. Serializers in Unity are specifically designed to operate efficiently at runtime. Because of this, serialization in Unity behaves differently to serialization in other programming environments. Serializers in Unity work directly on the fields of your C classes rather than their properties, so there are rules that your fields must conform to to be serialized. The following section outlines how to use field serialization in Unity. If you want to serialize these, you have two options:. When you assign an instance of a UnityEngine. Object -derived class to a field and Unity saves that field, Unity serializes the field as a reference to that instance. Object , Unity includes the state of the instance directly in the serialized data of the MonoBehaviour or ScriptableObject that references them. There are two ways that this can happen: inline and by [SerializeReference].

This causes significant problems for backwards compatibility: It carries serialize unity high risk of error because it is too easy for data to get out of sync.

Although we cannot accept all submissions, we do read each suggested change from our users and will make updates where applicable. For some reason your suggested change could not be submitted. And thank you for taking the time to help us improve the quality of Unity Documentation. When Unity serializes your scripts, it only serializes public fields. If you also want Unity to serialize your private fields you can add the SerializeField attribute to those fields. Unity serializes all your script components, reloads the new assemblies, and recreates your script components from the serialized versions.

To enable serialization, apply the [Serializable] attribute.

How you organise data in your Unity project affects how Unity serializes that data and can have a significant impact on the performance of your project. Hot reloading is the process of creating or editing scripts while the Editor is open and applying the script behaviors immediately. After reloading the scripts, Unity then restores them to their original, pre-serialization values. To ensure the fields of a custom class or struct are serialized, see How to ensure a field in a script is serialized , above. Many of the features in the Unity Editor are built on top of the core serialization system. The serializer does not support null. These are outlined below. All data that is not serializable is lost after the script is reloaded. Language: English. Outlined below are a number of tips on how to use serialization in Unity. Below is some guidance on serialization in Unity and how to optimize your project for it. Unity then creates a new GameObject and deserializes the data onto the new GameObject. If you store a reference to an instance of a custom class in several different fields, they become separate objects when serialized.

Then, when Unity deserializes the fields, they contain different distinct objects with identical data. With custom classes that are not derived from UnityEngine. Language: English. Object , Unity includes the state of the instance directly in the serialized data of the MonoBehaviour or ScriptableObject that references them. The restrictions above affect the majority of the Scripting API. Outlined below are a number of tips on how to use serialization in Unity. All data that is not serializable is lost after a hot reload. Everything that derives from UnityEngine. Object -derived class to a field and Unity saves that field, Unity serializes the field as a reference to that instance. Is public , or has a SerializeField attribute. Next, Unity runs the same serialization code in a different variant to report which other UnityEngine. However, Unity actually makes more than a thousand allocations. To fix this, edit your code so that it makes no Scripting API calls in any constructors for any serialized objects.
