How to save color

Questions & Answers

Hello, how would I save color on an object? Tried using Playerprefs but didn’t get it to work correctly. I have done some research, I found that you need to use playerprefsX but I have no idea how it works. Help would be appreciated.

Hi @unity_G2yrNlWYdpJKuw . Try this.

 void SaveColor(Color color)
    {
    PlayerPrefs.SetString("SavedColor", ColorToHex(color));
    }
    void GetSavedColor()
    {
          Color GetedColor=  HexToColor(PlayerPrefs.GetString("SavedColor"));
    }
    // Note that Color32 and Color implictly convert to each other. You may pass a Color object to this method without first casting it.
    string ColorToHex(Color32 color)
    {
    	string hex = color.r.ToString("X2") + color.g.ToString("X2") + color.b.ToString("X2");
    	return hex;
    }
     
    Color HexToColor(string hex)
    {
    	byte r = byte.Parse(hex.Substring(0,2), System.Globalization.NumberStyles.HexNumber);
    	byte g = byte.Parse(hex.Substring(2,2), System.Globalization.NumberStyles.HexNumber);
    	byte b = byte.Parse(hex.Substring(4,2), System.Globalization.NumberStyles.HexNumber);
    	return new Color32(r,g,b, 255);
    }

hey @unity_G2yrNlWYdpJKuw . use this code. for save and get save color just you need to call. SaveColor() and GetSaveColor().
u can also set and get Collor Array at a time.

public class MyPlayerPrefs : MonoBehaviour
{

public static Color GetSaveColor (string key)
{
	string col = PlayerPrefs.GetString (key);

	Debug.Log (col);

	if (col == "")
	{
		return Color.black;
	}

	string[] strings = col.Split (',');

	Color output = new Color ();

	for (int i = 0; i < 4; i++)
	{
		output  _= System.Single.Parse (strings *);*_

* }*
* return output;*
* }*
* public static bool CheckColor (string key)*
* {*
* if (PlayerPrefs.HasKey (key))*
* return true;*
* else*
* return false;*
* }*
* public static void SaveColor (Color color, string key)*
* {*
* string col = color.ToString ();*
* col = col.Replace (“RGBA(”, “”);*
* col = col.Replace (“)”, “”);*
* PlayerPrefs.SetString (key, col); *
* }*
* public static void SaveColorArray (Color[] col, string key)*
* {*
* int i = 0; *
* PlayerPrefs.SetInt (key, col.Length);*
* foreach (Color c in col)*
* {*
* SaveColor (c, key + i++);*
* }*
* }*
* public static Color[] GetSaveColorArray (string key)*
* {*
* if (!PlayerPrefs.HasKey (key))*
* return null;*
* int len = PlayerPrefs.GetInt (key);*
* Color[] tem = new Color[len];*
* for (int i = 0; i < len; i++)*
* {*
_ tem = GetSaveColor (key + i);
* }
 return tem;
 }
}*_

Instead of writing your own methods, you could use unity’s ColorUtility class:

// Store single color
Color color;
PlayerPrefs.SetString("ColorKey", ColorUtility.ToHtmlStringRGB(color)); // without alpha
PlayerPrefs.SetString("ColorKey", ColorUtility.ToHtmlStringRGBA(color)); // with alpha

// Load single color
Color color;
ColorUtility.TryParseHtmlString("#" + PlayerPrefs.GetString("ColorKey"), out color);

// store color array
Color[] colors; 
//// fill array with your colors ////
int numberOfColors = colors.Length;
for (int i = 0; i < numberOfColors; i++){
  Color color = colors*;*

PlayerPrefs.SetString(“ColorKey” + i, ColorUtility.ToHtmlStringRGBA(color)); // with alpha
}

// load color array
Color[] colors = new Color[numberOfColors];
for (int i = 0; i < numberOfColors; i++){
ColorUtility.TryParseHtmlString(“#” + PlayerPrefs.GetString(“ColorKey” + i), out colors*);*
}
Edit: Adding “#” in front of colorHtmlString is required (see: Unity - Scripting API: ColorUtility.TryParseHtmlString)
