Content seems good, but support files/code are insufficient, and the code seems illogical in places
Format: Paperback
This books starts out great and the content/approach seems solid. But I ran into several issues when the coding portions were introduced, notably when it came to collisions and destroying enemy game objects. There's scripting to set up a bullet behavior, but from the outset the behavior is buggy, and when the "explosion" behavior is introduced, there's no coding to actually destroy the object you're introducing the explosion behavior to. On top of that, the explosion behavior is tied to the playerObj's "onDeath" function, so ... I'm not sure how any of that ties into destroying an enemy game object. This is about 150 pages in. The go-to method in these cases is, of course, to reference the support files, but these files only include the code and the book images. What's really needed is the Unity project files to ensure the code is being implemented in the components of the game objects and seeing the core structure there. With only the scripts, you can only check your scripts against those, but you can't be sure you're utilizing them correctly and tying it all together in Unity. Granted, I'm still learning the platform, but things like where you're expected to fire a bullet that has no "destroy gameObject" function into an enemy gameObject that also has no such behavior ... and the behavior is tied to the player? There's definitely something amiss. All the while you're dealing with "soft locks" in the test gameplay that could have been immediately addressed, but aren't. And you can't really move forward with such core inconsistencies in place because you fear the problems would just compound from there.

Easy to follow
Format: Paperback
My children are able to follow along. Directions aren't too simplistic nor too complicated. Good for adults too. They are using the skills they learned and adding new ones. Happy with this purchase.
