Невозможно загрузить контент, если он не в основном игровом классе

public class Dirt : Tile

    public Dirt(Game game, Vector2 Position)

        type = "dirt";
        textureName = "Textures/Dirt";

        position = Position;
    }

    public override void Initialize()

        base.Initialize();
    }

    protected override void LoadContent()
    {
        texture = Salvage.contentManager.Load<Texture2D>("Textures/Dirt"); // This doesnt work

        base.LoadContent();
    }

    public override void Update(GameTime gameTime)
    {
        if (InputHandler.KeyDown(Keys.W))

        {
            position.Y += 1;
        }

        if (InputHandler.KeyDown(Keys.D))
        {
            position.X += 1;
        }
        else if (InputHandler.KeyDown(Keys.A))
        {
            position.X -= 1;
        }

        Camera.DesiredPosition = position;

        base.Update(gameTime);
    }

    public override void Draw(GameTime gameTime)
    {
        Salvage.spriteBatch.Begin(SpriteSortMode.BackToFront, BlendState.AlphaBlend, null, null, null, null, Camera.Transformation);
        Salvage.spriteBatch.Draw(texture, position, Color.White);
        Salvage.spriteBatch.End();


        base.Draw(gameTime);
    }
}

Загрузка работает нормально, если я загружаю ее в класс Salvage (класс основной игры).

Редактировать:

Ошибка, которую я получаю:

Salvage.spriteBatch.Draw(texture, position, Color.White); Этот метод не принимает null для этого параметра. Имя параметра: текстура

Вот код класса Salvage:

public class Salvage : Microsoft.Xna.Framework.Game
{

    public static GraphicsDeviceManager graphics;
    public static SpriteBatch spriteBatch;
    public static ContentManager contentManager;
    public static SpriteFont spriteFont;
    public GameStateManager stateManager;
    public Rectangle ScreenRectangle = new Rectangle(0, 0, 1024, 768);

    public Salvage()
    {
        graphics = new GraphicsDeviceManager(this);
        graphics.PreferredBackBufferHeight = ScreenRectangle.Height;
        graphics.PreferredBackBufferWidth = ScreenRectangle.Width;

        Content.RootDirectory = "Content";
        contentManager = Content;

    }

    protected override void Initialize()
    {

        base.Initialize();
    }

    protected override void LoadContent()
    {
        spriteBatch = new SpriteBatch(GraphicsDevice);
        spriteFont = Content.Load<SpriteFont>("Fonts/DefaultSpriteFont"); // This works fine

        stateManager = new GameStateManager(this);
        GameplayState gameplayState = new GameplayState(this, stateManager);

        Components.Add(new InputHandler(this));
        Components.Add(new Camera(this, ScreenRectangle));
        Components.Add(stateManager);

        stateManager.ChangeState(gameplayState);

    }


    protected override void UnloadContent()
    {

    }

    protected override void Update(GameTime gameTime)
    {
        if (GamePad.GetState(PlayerIndex.One).Buttons.Back == ButtonState.Pressed || InputHandler.KeyReleased(Keys.Escape))
            this.Exit();

        base.Update(gameTime);
    }

    protected override void Draw(GameTime gameTime)
    {
        GraphicsDevice.Clear(Color.CornflowerBlue);

        base.Draw(gameTime);
    }
}

И код для плитки

public abstract class Tile : Microsoft.Xna.Framework.DrawableGameComponent
{
    public string textureName;
    public string type;

    public Tile(Game game)
        : base(game)
    {

    }

    public override void Initialize()
    {

        base.Initialize();
    }

    protected override void LoadContent()
    {

        base.LoadContent();
    }

    public override void Update(GameTime gameTime)
    {

        base.Update(gameTime);
    }

    public override void Draw(GameTime gameTime)
    {

        base.Draw(gameTime);
    }
}

Редактировать:

Вот класс GamePlayState

public class GameplayState : GameState
{

    public GameplayState(Game game, GameStateManager manager)
        : base(game, manager)
    {
        childGameComponents.Add(new Dirt(game, new Vector2(0, 0)));
    }

    public override void Initialize()
    {

        base.Initialize();
    }

    protected override void LoadContent()
    {
        base.LoadContent();
    }

    public override void Update(GameTime gameTime)
    {

        base.Update(gameTime);
    }

    public override void Draw(GameTime gameTime)
    {

        base.Draw(gameTime);
    }
}
