Save iDictionary

[morrigan]

Hello everybody, I am trying to complete the saving system of my project. This is the last part I guess!
I have a Text.Ui with a script that implements iDictionary to replace letters. Can I use the LoadDictionary method to save it? I've tried to save it, but the only error I get is about the variable I'm trying to access, which is non-static, so I don't know if it does work. This is the code with the Easy Save methods.

Code: Select all

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text.RegularExpressions;
using UnityEngine;
using UnityEngine.UI;


public class ColorText: MonoBehaviour
{
	static ColorText instance;
	static	Text myText;
	string baseString;
	IDictionary<string,string> characterMap = new Dictionary<string,string> ();


	void Awake()
	{
		instance = this;
		myText = GetComponent<Text>();
		ChangeText(myText.text);
	}


	public static void AddColor(string letterAlphabet, Color textColor)
	{
		if(instance==null)
		{
			return;
		}

		letterAlphabet = Regex.Escape(letterAlphabet);
		instance.characterMap[letterAlphabet] = "<color=#"+ColorToHex(textColor)+">"+letterAlphabet+"</color>";
		instance.Format();
	}

	public static void RemoveColor(string letterAlphabet)
	{
		if(instance==null)
		{
			return;
		}

		letterAlphabet = Regex.Escape(letterAlphabet);
		if(instance.characterMap.ContainsKey(letterAlphabet))
		{
			instance.characterMap.Remove(letterAlphabet);
		}

		instance.Format();
	}

	public static void ChangeText(string newString)
	{
		if(instance==null)
		{
			return;
		}
		instance.baseString = newString;
		instance.Format();
	}

	static	string ColorToHex (Color textColor)
	{
		string hex  = ((int)(textColor.r * 255)).ToString("X2")
			+ ((int)(textColor.g * 255)).ToString("X2")
			+ ((int)(textColor.b * 255)).ToString("X2")
			+ ((int)(textColor.a * 255)).ToString("X2");

		return hex;
	}

	void Format()
	{
		if(characterMap.Count==0)
		{
			myText.text = baseString;
			return;
		}

		Regex regex = new Regex (String.Join ("|", characterMap.Keys.ToArray()));
		myText.text = regex.Replace (baseString, m => characterMap [m.Value]);
		if (ES2.Exists ("sleepsavefile.txt?tag=Text Saved")) 
		{
			instance.characterMap = ES2.LoadDictionary<string, string> ("sleepsavefile.txt?tag=Text Saved");
		}
	}

	public static void  saveText()
	{
		ES2.Save(characterMap, "sleepsavefile.txt?tag=Text Saved");
	}

}

Hi there,

Because IDictionary is an interface, it's not possible to serialise it because you cannot instantiate interfaces.

The easiest way to fix this is to change your characterMap variable from an IDictionary to a Dictionary. i.e.

Change this:

IDictionary<string,string> characterMap = new Dictionary<string,string> ();

To this:

Dictionary<string,string> characterMap = new Dictionary<string,string> ();

All the best,
Joel

Okay, I had to fix a couple of errors in my code, but now everything works perfectly. Thank you very much Joel!

Hello, I´m going to release it to iOS and Android.
That works on both systems??

Thanks!

[Joel]

I see no reason why it shouldn't. Dictionary is supported on both platforms.

In your docs says it´s not compatible:

Thanks!

I believe this is a limitation in earlier versions of Unity, but not not since Unity 4.

I'll remove the comment as this is no longer an issue.
