What? I'm back on Tuesday...

I'm back on thursday :P 

Wanna know what sucks?

This sucks:

// Background(s) code

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using Microsoft.Xna.Framework;
using Microsoft.Xna.Framework.Content;
using Microsoft.Xna.Framework.Graphics;

namespace Shooter
{
    class ParallaxingBackground
    {
        // The imag representing the parallaxing background
        Texture2D texture;

        // An array of positions of the parallaxing background
        Vector2[] positions;

        // The speed which the background is moving at
        int speed;
       
        public void Initialize(ContentManager content, String texturePath, int screenWidth, int speed)
        {
            // Load the background texture we will be using
            texture = content.Load(texturePath);

            // Set the speed of the background
            this.speed = speed;

            // If we divide the screen with the texture width then we can determin the number o tiles we need
            // We add 1 to it so that we won't have a gap in the tiling
            positions = new Vector2[screenWidth / texture.Width + 1];

            // Set the initial positions of the parallaxing background
            for (int i = 0; i < positions.Length; i++)
            {
                // We need the tiles to be side by side to create a tiling effect
                positions = new Vector2(i * texture.Width, 0);
            }
        }

        public void Update()
        {
            // Update the positions of the background
            for (int i = 0; i < positions.Length; i++)
            {
                // Update the position of the screen by adding the speed
                positions.X += speed;

                // If the speed has the background moving to the left
                if (speed <= 0)
                {
                    // Check the texture is out of view then put that texture at the end of the screen
                    if (positions.X <= texture.Width)
                    {
                        positions.X = texture.Width * (positions.Length - 1);
                    }

                    // If the speed has the background moving to the right
                    else
                    {
                        // Check if the texture is out of view then position to the start of the screen
                        if (positions.X >= texture.Width * (positions.Length - 1))
                        {
                            positions.X = texture.Width;
                        }
                    }
                }
            }
        }

        public void Draw(SpriteBatch spriteBatch)
        {
            spriteBatch.Draw(texture, positions, Color.White);
        }
    }
}
