How to draw the elements that are in a Texture2D list in XNA

Question

I have a Texture2D list called blockTexture that has 2 elements in it.

I use the following line to draw the first element.

foreach (Vector2 blockPosition in blockPositions)
for (int i = 0; i < blockPositions.Count; i++)
{
 spriteBatch.Draw(blockTexture[i], blockPositions[i], Color.White);
}

This allows me to draw the elements in different positions. However, while I run it after like 3-4 seconds it gives OutOfRangeArgument error.

I was wondering what am I doing wrong or is there another way to do this. I'm really sorry if my question sounds stupid but I'm a total beginner.

PS: this is a game where different type of objects fall from the top of the screen to the bottom, and the person at the bottom needs to avoid some of the objects and try to catch the others.

List<Vector2> blockPositions = new List<Vector2>();
List<Texture2D> blockTexture = new List<Texture2D>();

These are in the load content

blockTexture.Add(Content.Load<Texture2D>("Block"));
blockTexture.Add(Content.Load<Texture2D>("right"));

These are in the update section

for (int i = 0; i < blockPositions.Count; i++)
 {
  // Animate this block falling
  blockPositions[i] =
  new Vector2(blockPositions[i].X, blockPositions[i].Y + BlockFallSpeed);

  // Get the bounding rectangle of this block
  Rectangle sprite =
  new Rectangle((int)blockPositions[i].X, (int)blockPositions[i].Y,
                    blockTexture[0].Width, blockTexture[0].Height);


  // check collision with person
  if (personRectangle.Intersects(sprite))
   personHit = true;

  // Remove this block if it have fallen off the screen
   if ((blockPositions[i].Y > Window.ClientBounds.Height))
   {
    blockPositions.RemoveAt(i);
   // When removing a block, the next block will have the same index
   // as the current block. Decrement i to prevent skipping a block.
    i--;
    }
  }

  base.Update(gameTime);

}

Answer 1

I would do it so, so it can be safer and maybe easier to use :

Just use a class to hold the information of position and texture.

class yourClass
{
    Texture2D texture;
    Vector2 position;

    public yourClass()
    {

    }

    //your functions
    //...
}

And then you can use a List of this class, like:

List<yourClass> list = new List<yourClass>();

yourClass a = new yourClass();
a.texture = Content.Load<Texture2D>("blabla");
a.position = new Vector2(0, 0, 800, 800);
list.Add(a);
//...

Answer 2

This is a bit of a shot in the dark, since I'm just guessing at your intentions here. But I think you would want to change your drawing code to the following:

foreach (Vector2 blockPosition in blockPositions)
{
     for (int i = 0; i < blockTexture.Count; i++)
     {
           spriteBatch.Draw(blockTexture[i], blockPosition, Color.White);
     }
}
