Program line in the Draw method


Line in code: GraphicsDevice.Clear(Color.CornflowerBlue);

Should probably be: GraphicsDevice.Clear(Color.Black);

Chapter 3: Layer Depth

Aaron states that calling ?spriteBatch.Begin(SpriteSortMode.FrontToBack...);? will set your program to render sprites with smaller depth values on top of those with larger depth values. This is backwards. It renders those with larger depth values on top of those with smaller depth values. In order to get Aaron?s provided source code to work, programmers must call ?spriteBatch.Begin(SpriteSortMode.BackToFront...);?

Code at the end of the page

In the code example, the line 'Point skullSheetSize = new Point(6, 8);' should be 'Point skullSheetSize = new Point(5, 7);', because the related Sprite Sheet has 6 columns and 8 lines, but the 'Point CurrentFrame' always starts with the value (0, 0), so when the Sheet Size is being declared as 6, 8, it's actually being count as 7, 9, resulting in a quick and unexpected blink in each frame out of bounds.

Middle of page, after 2nd paragraph.

The instructions indicate that it is necessary to include the line:

GraphicsDevice.SetVertexBuffer(vertexBuffer);

...when in fact the triangle is drawn using a call to GraphicsDevice.DrawUserPrimitives, making the call to SetVertexBuffer superfluous. In fact, the vertex buffer is never used at all. It can be removed without affecting the drawing code whatsoever.

TriangleFan primitive was removed from XNA in version 4.0- now there are LineList and LineStrip instead.
