This is a simple C# script example for a C# class Player.
The class Player come with this content into Player.cs C# script:
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 |
using UnityEngine; using System.Collections; public class Player : MonoBehaviour { public int level = 1; public int energy = 100; public int health = 100; public int attack = 5; public int defense = 2; //make Save and Load public void Save() { SaveLoadManager.SavePlayer(this); } public void Load() { int[] loadStat = SaveLoadManager.LoadPlayer(); level = loadStat[0]; energy = loadStat[1]; health = loadStat[2]; attack = loadStat[3]; defense = loadStat[4]; } // Use this for initialization void Start () { } // Update is called once per frame void Update () { } } |
To make this C# script for saving the Player into one file I used this C# script named SaveLoadManager.cs:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 |
using UnityEngine; using System; using System.Collections; using System.Runtime.Serialization.Formatters.Binary; using System.IO; public static class SaveLoadManager { public static void SavePlayer(Player player) { //create binary file BinaryFormatter bf = new BinaryFormatter(); FileStream stream = new FileStream(Application.persistentDataPath+"/player.sav",FileMode.Create); //this will use the class PlayerData PlayerData data = new PlayerData(player); //use Serialize - bf.Serialize(stream, data); //close file stream stream.Close(); } //load the file public static int[] LoadPlayer() { //check the file exist if (File.Exists(Application.persistentDataPath + "/player.sav")) { //open binary file BinaryFormatter bf = new BinaryFormatter(); FileStream stream = new FileStream(Application.persistentDataPath + "/player.sav", FileMode.Open); PlayerData data = bf.Deserialize(stream) as PlayerData; //close file stream stream.Close(); //return data from file return data.stats; } else { Debug.LogError("File don't exist!"); return new int[5]; } } } // need to use using System; to use Serializable area. [Serializable] public class PlayerData { // more convenient for us to store data public int[] stats; public PlayerData(Player player) { stats = new int[5]; stats[0] = player.level; stats[1] = player.energy; stats[2] = player.health; stats[3] = player.attack; stats[4] = player.defense; } } |
The script come with two parts for save and load files.
I used Serializable property to save binary file named player.sav.
This script used also the Application.persistentDataPath to take the path of application.
I used a Debug log output but if you want to used into real application then is no need to use.
You can deal with any player settings and make new like: player.magic or player.status.
Take a look at the comments in the script and that script highlights design issues.
