Question

Can anyone else make and compile this program(Click here) up until the first “quick build”..? (right up to the point where they say “This would be a great time to do a quick build”)

For some reason i keep getting this exception!

I’ve checked everything mentioned in this Stackoverflow solution: Click Here but none of it has solved my issue 🙁

my image is placed in the Content area. It is not located in a folder.

Please help!

here is what my code looks like:

namespace myGame
{

    public class Game1 : Microsoft.Xna.Framework.Game
    {
        GraphicsDeviceManager graphics;
        SpriteBatch spriteBatch;

        SpriteBatch mBatch;
        Texture2D mHealthBar;

        public Game1()
        {
            graphics = new GraphicsDeviceManager(this);
            Content.RootDirectory = "Content";
        }





        protected override void Initialize()
        {
            // TODO: Add your initialization logic here

            base.Initialize();
        }





        protected override void LoadContent()
        {

            spriteBatch = new SpriteBatch(GraphicsDevice);

            // TODO: use this.Content to load your game content here
            mBatch = new SpriteBatch(this.graphics.GraphicsDevice);
            ContentManager aLoader = new ContentManager(this.Services);

            **//ERROR occurs here!**
            mHealthBar = aLoader.Load<Texture2D>("HealthBar") as Texture2D;
        }




        protected override void UnloadContent()
        {
            // TODO: Unload any non ContentManager content here
        }




        protected override void Update(GameTime gameTime)
        {
            // Allows the game to exit
            if (GamePad.GetState(PlayerIndex.One).Buttons.Back == ButtonState.Pressed)
                this.Exit();

            // TODO: Add your update logic here

            base.Update(gameTime);
        }





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

            // TODO: Add your drawing code here
            mBatch.Begin();
            mBatch.Draw(mHealthBar, new Rectangle(this.Window.ClientBounds.Width / 2 - mHealthBar.Width / 2,

                 30, mHealthBar.Width, 44), new Rectangle(0, 45, mHealthBar.Width, 44), Color.Red);


            //Draw the box around the health bar
            mBatch.Draw(mHealthBar, new Rectangle(this.Window.ClientBounds.Width / 2 - mHealthBar.Width / 2,
                  30, mHealthBar.Width, 44), new Rectangle(0, 0, mHealthBar.Width, 44), Color.White);
            mBatch.End(); 
            base.Draw(gameTime);
        }
    }
}

If you followed the tutorial precisely, you have added the image to the game project instead of the content project. This is a result of following a vastly outdated tutorial (1.0 vs the current 4.0)

Right click on the Content Project, add existing file and add the image.

As a side note, I HIGHLY suggest you File>New and do the tutorials at http://www.riemers.net/
There are too many code breaking changes from 1.0 to 4.0 to even attempt to do a 1.0 tutorial.
