Save and share from Web Player

There are several ways you can do it. Either you can send the saved preferences as a Base 64 encoded string (suitable when you don't have too many bytes of info). Otherwise you could set up a server that stores preferences in a database and provides keys to look them up later.

Base64 encoding is just taking any binary blob of data and transforming it into a string containing safe and normal characters.

Example to encode/decode a color:

 using UnityEngine;
 using System.Collections;
 
 public class ColorBase64 : MonoBehaviour
 {    
     public Color color = Color.cyan;
     
     void Start () {        
         Debug.Log ("Color to store as Base64: " + color);
         string base64 = ColorToBase64 (color);
         Debug.Log ("Color stored as Base64 string: " + base64);
         Color color2 = Base64ToColor (base64);
         Debug.Log ("Color loaded from Base64: " + color2);
     }
 
     string ColorToBase64 (Color color) {
         return System.Convert.ToBase64String (ToBytes (color));
     }
 
     Color Base64ToColor (string base64) {
         return ToColor (System.Convert.FromBase64String (base64));
     }
 
     static byte[] ToBytes (Color color) {
         byte[] colorAsBytes = new byte[4];        
         colorAsBytes [0] = (byte)(color.a * 255);
         colorAsBytes [1] = (byte)(color.r * 255);
         colorAsBytes [2] = (byte)(color.g * 255);
         colorAsBytes [3] = (byte)(color.b * 255);
         return colorAsBytes;
     }
 
     static Color ToColor (byte[] bytes) {
         float a = bytes [0];
         float r = bytes [1];
         float g = bytes [2];
         float b = bytes [3];
         return new Color (r / 255.0f, g / 255.0f, b / 255.0f, a / 255.0f);
     }
 }

Example output:

 Color to store as Base64: RGBA(0.443, 0.761, 0.548, 1.000)
 Color stored as Base64 string: /3DCiw==
 Color loaded from Base64: RGBA(0.439, 0.761, 0.545, 1.000)
