How to store a sprite in a global variable using c# script after touch event in unity for a 2D game?

Question

I am new to unity and want to store a sprite in a global variable to access in other scene after touch event occurs. Any idea in this regard will be appreciated.

Answer 1

I would like to propose an approach to solve this case.

Define a sprite manager class "MySpriteManager" as follows:

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

public class MySpriteManager {
    private static Dictionary<string, Sprite> spriteMap = new Dictionary<string, Sprite>();

    public static void AddSprite(string key, Sprite value) {
        spriteMap.add(key, value);
    }

    public static Sprite GetSprite(string key) {
        return spriteMap[key];
    }
}

Whenever you want to save a sprite instance for future uses,

MySpriteManager.AddSprite("my_sprite_key", my_sprite_instance);

To retrieve a previously saved sprite instance,

Sprite savedSprite = MySpriteManager.GetSprite("my_sprite_key");

Hopefully the idea is illustrated clearly enough.
