Texture2D Rotate180(Texture2D tex)
{
    int width = tex.width;
    int height = tex.height;
    Texture2D newTexture = new Texture2D(width, height);
    for (int i = 0; i < width; i++)
    {
        for (int j = 0; j < height; j++)
        {
            Color color = tex.GetPixel(i, j);
            newTexture.SetPixel(width - i, height - j, color);
        }
    }
    newTexture.Apply();
    return newTexture;
