Problem with SetPixel in a sprite

Unity Engine
1

Hi All,

I am trying to change the texture of a sprite with SetPixel. It works, but the problem is that the changes are persistent. If I stop the game, the texture stays changed.

This is my code:

void Start()
{
       //create a copy of the original sprite and set it to the sprite
       Sprite temp_sprite = Instantiate(gameObject.GetComponent<SpriteRenderer> ().sprite) as Sprite;
       gameObject.GetComponent<SpriteRenderer> ().sprite = temp_sprite;

       //draw the pixels
        int y = 0;
        while (y < temp_sprite.texture.height)
        {
            int x = 0;
            while (x < 10) {
                Color color = Color.blue;
                temp_sprite.texture.SetPixel(x, y, color);
                ++x;
            }
            y++;
        }
        //apply the texture to the sprite
        temp_sprite.texture.Apply();
}

I have no idea why it does not work. Am I making a mistake in the copy somewhere?

shameless bump

Edit:

Never mind. Solved with Sprite.Create

Had this problem also, I too fixed it with Sprite.Create but would still like to know what’s wrong.
