Oops!

Writing a textbook is a lot of work and there are a lot of people involved - editors, copy editors, proof readers, reviewers, and of course an author. Even with all of those people reading and re-reading everything, typos, errors, and omissions happen. On this page you'll find a list of all of the issues that have been reported so far. If you find a problem that isn't listed on this page, please reach out to me at welcomebraveadventurer@gmail.com to let me know about it!

• Front matter: Joshua Roberson should say Joshua Robertson. Sorry Josh.
• Page 91 - Figures 9.1 and 9.2 are missing a ? in the Code Quest prompt. It should look like this: What is your character's damage per turn?:
• Page 120 - For instruction e, the word appropriate would make things a bit clearer. It should read: Use the appropriate built-in Math library function here.
• Page 135 - Instruction 6 should read: Finally, show the hero’s final health value. Don't worry if your hero's health is 0 or a negative number. It just means they are having a really bad day.
• Page 185 - there is a typo at the bottom of Code Reward 8. + " health, " + specialSkillsPoint should be + " health, " + specialSkillPoints

• Page 132 (Thanks Brianna for finding this one): The last paragraph before Mouse Buttons should read:

Before we move on to exploring mouse buttons, if you left the keyboard statements intact and wrote the mouse statements below, you'll probably find that you can't use the keyboard (WASD) any more. It's not that the program isn't checking for the key presses, it's that the _heroX and _heroY are being set to the mouse coordinates and the WASD input is being overridden during each Update(). To get your WASD keyboard movement back, simply comment out the two last lines like this:

//_heroX = currentMouseState.X;

//_heroY = currentMouseState.Y;

We'll look at mouse button clicking and drag-and-drop - both of which are more effective than simply following the mouse position - in the next two sections.

• Page 144: This logic is very similar to the rotation logic that is assigned to the z and x keys in the CQ7Start (not CodeQuest7Start) project.
• Page 215: Both the space hero (not here) and the chest have GetBounds() methods. 
• Page 236: In Game1, find the loop (word missing) in Update() where we remove the star objects from their list after left‑clicking on them.
