Serializable

Description

Indicates that a class or a struct can be serialized.

To enable serialization, apply the [Serializable] attribute. For more information on serialization, see Script Serialization.

Note: Only non-abstract, non-generic custom classes can be serialized.

In the following example we create a custom Player struct and give it the [Serializable] attribute to make it serializable. We then create a private field of the Player type and apply [SerializeField] attribute to it to make it show up in the Inspector.

using System;
using UnityEngine;

public class Player : MonoBehaviour
{
    //Create a custom struct and apply [Serializable] attribute to it
    [Serializable]
    public struct PlayerStats
    {
        public int movementSpeed;
        public int hitPoints;
        public bool hasHealthPotion;
    }

    //Make the private field of our PlayerStats struct visible in the Inspector
    //by applying [SerializeField] attribute to it
    [SerializeField]
    private PlayerStats stats;
}
