Serialize unity

Some of the built-in features of Unity automatically use serialization. These are outlined below.

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.

Serialization is the automatic process of transforming data structures or object states into a format that Unity can store and reconstruct later. See documentation on Built-in serialization use for background details on all of these. 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. Below is some guidance on serialization in Unity and how to optimize your project for it. Hot reloading is the process of creating or editing scripts while the Editor is open and applying the script behaviors immediately. You do not have to restart the game or Editor for changes to take effect. When you change and save a script, Unity hot reloads all the currently loaded script data. It first stores all serializable variables in all loaded scripts and, after loading the scripts, it restores them. All data that is not serializable is lost after a hot reload. Many of the features in the Unity Editor build on top of the core serialization system. Two things to be particularly aware of with serialization are the Inspector window , and hot reloading.

Thank you for helping us improve the quality of Unity Documentation. 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. To enable serialization, apply the [Serializable] attribute. For more information on serialization, see Script Serialization. This attribute is not required for classes that derive from serialized Unity classes, such as MonoBehaviour , ScriptableObject and ScriptedImporter.

This prevents Unity from creating multiple objects from object references. Version: Versions without this page:. In some cases, you specifically need to prevent private variables from being restored: For example, if you want a reference to be null after reloading from scripts. Only some parts of the Unity scripting API are exempt and you can call them from anywhere:. See the documentation on Script Serialization for further information. Object -derived class, such as public Camera myCamera , Unity serializes an actual reference to the camera UnityEngine. The reason for these limitations is that one of the core foundations of the serialization system is that the layout of the datastream for an object is known ahead of time; it depends on the types of the fields of the class, rather than what happens to be stored inside the fields. The prefab acts as a template from which you can create new object instances in the scene. The best approach is to implement the ISerializationCallbackReceiver interface in your class. Unity stores all serializable variables in all loaded scripts, then reloads those scripts and restores the serialized variables.

This is how Textures that were used by one scene are unloaded in the next. If you want to serialize these, you have two options: wrap the nested type in a class or struct, or use serialization callbacks ISerializationCallbackReceiver to perform custom serialization. Serialization is the automatic process of transforming data structures or object states into a format that Unity can store and reconstruct later. Unity User Manual This causes significant problems for backwards compatibility: It carries a high risk of error because it is too easy for data to get out of sync. Other Versions Cannot access other versions offline! Many of the features in the Unity Editor are built on top of the core serialization system. This means that: While the values of a field in the Inspector window represent script properties, changes to values in the Inspector window do not call any property getters and setters in your script. Object Unity serializes them inline by value, similar to the way it serializes structs. Publication
