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 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.

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].

Serializers in Unity run in a serialize unity game environment. After reloading the scripts, Unity then restores them to their original, pre-serialization values. Scripting restrictions.

.

This includes data saved in your own script objects such as MonoBehaviour components and ScriptableObjects. Additionally, many of the features in the Unity Editor build on top of the core serialization system. To give you an understanding of how serialization works in Unity, the following sections provide a list of the built-in features of Unity that use serialization. Data saved in script objects in the form of MonoBehaviour components and ScriptableObjects are saved and loaded using serialization. This happen at runtime when running your game, but also at many other points in time, as is detailed below. It asks the object to serialize itself, and then displays this serialized data. Internally, a Prefab is the serialized data stream of one or more GameObjects and components. A Prefab instance is a list of modifications that should be made on the serialized data for this instance.

Implemented in: UnityEngine. 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. 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.

The following section outlines how to use field serialization in Unity. Version: Many of the features in the Unity Editor are built on top of the core serialization system. See documentation on Built-in serialization use for background details on all of these. Legacy Documentation: Version 5. Is public , or has a SerializeField attribute. Publication Note : Unity does not support serialization of multilevel types multidimensional arrays, jagged arrays, and nested container types. A Prefab An asset type that allows you to store a GameObject complete with components and properties. The serializer does not support null. You do not have to restart the game or Editor for changes to take effect. A Prefab instance contains a reference to both the Prefab source and a list of modifications to it. There are two ways that this can happen: inline and by [SerializeReference]. When you call Instantiate on anything that exists in a scene, such as a Prefab or a GameObject:. When reloading scripts, Unity serializes and stores all variables in all loaded scripts.

Implemented in: UnityEngine.

Start instead of in the constructor. To ensure the fields of a custom class or struct are serialized, see How to ensure a field in a script is serialized , above. Language: English. 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. 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. Custom non-abstract, non-generic classes with the Serializable attribute See How to ensure a custom class can be serialized , below. Object -derived class to a field and Unity saves that field, Unity serializes the field as a reference to that instance. When you change and save a script, Unity hot reloads all the currently loaded script data. Objects to see if they are part of the data being instantiated. This has a significant impact on performance. Objects are being referenced.
