Testing out Unity's serialization system

GameData.cs

using System;
using UnityEngine;
using System.Collections.Generic;

public class GameData : MonoBehaviour
{
    //
    // Serialization rule for fields
    //

    public int playerHealth;

    [NonSerialized]
    public float playerReloadTime;

    [HideInInspector]
    public float playerJumpTime;

    private int maxLife;

    [SerializeField]
    private int maxAmmoCount;

    // Can't serialize auto-generated property fields
    public float EnemyCount { get; set; }

    // So serialize like this (blame Unity)
    [SerializeField]
    private float timeLeft;
    public float TimeLeft
    {
        get { return timeLeft; }
        set { timeLeft = value; }
    }

    //
    // Serialization rule for references
    //

    // UnityEngine.Object references can be serialized
    public Sprite playerHitSprite;
    public Camera camera;

    // System.Object references need [Serializeable] attribute
    [System.Serializable]
    public class Song
    {
        public string name;
        public int bpm;
        public AudioClip clip;
    }

    // Both arrays and lists are supported...
    public Song[] songArray;
    public List<Song> songList;

    // but Dictionaries are not
    public Dictionary<string, Song> songPerLevelDict;
}
